If you find anything that does not make sense or you feel there should be a specific picture please let me know. Knowing the machine as well as I do I have a hard time knowing which parts need better explaining. I will be adding more videos and tutorials in the coming weeks. <a href="http://www.tantillus.org/Build_0.html" target="_blank">Tantillus.org Build Guide</a><br />
<br />
A few notes to supporters of the Indiegogo campaign.<br />
<br />
1) All the hardware and complete kits include two Bowden tubes. One is 1/4" x 1/8" which has an inside diameter of 3.06mm. The other is 1/4" x 3/16" which has an inside diameter of 4.7mm. Although the 3.06mm i.d. tubing is the proper tubing for the machine it can be too small for Chinese made filament which is 3mm +/- 0.1mm. If you plan on using high end filament that measures 2.8 or 2.9 +/- 0.1mm you should use the 3.06mm i.d. tubing as it allows you to change filament on the fly by inserting one piece after another. If you are using cheaper filament that has the possibility to go over 3mm use the 4.7mm i.d. tubing and be aware that you can not change filament on the fly because they try and pass each other in the tube and cause a jam.<br />
<br />
2) I've included extra of the smaller size nuts as I know how easy it is to lose them. <br />
<br />
3) I some how forgot to include two size Allen keys required to assemble the deluxe complete kits, 7/64" and 3/32" . I am more than willing to send these to everyone that ordered but I am not sure any of you will want to wait. Please let me know what you would like me to do. The 7/64" is for the carriage assembly which can be tightened via the nuts and the extruder idler which can also be tightened via the nuts and only needs to be hand tight. The 3/32" is for the LCD, Arduino and Z-coupler and is requied to tighten the Z-coupler.<br />
<br />
4) If you have not been contacted about shipping or pick up or you are waiting for a response that just never seems to come please contact me. There are a couple of you that I have tried contacting on multiple occasions and have not gotten a response. This is most likely due to a spam filter. For guaranteed contact you can use the RepRap forums mail system as it is does not filter the content. <br />
<br />
5) If you ordered a Hardware kit for the fully printed case you will find that it is missing the bolts that hold the corners together. They are also missing the washers used to adjust the force of the upper stiffeners. It is 8 nuts and bolts and 16 washers that are missing. If you are willing to wait I am more than willing to send them to you. If you are in a hurry to assemble your machine it will most likely be easier to get them locally. Please let me know what you would like me to do.<br />
<br />
I would like to thank everyone that contributed to the Indiegogo campaign for their patience and understanding. This has been a real learning experience and far more work than I could have ever anticipated. After filling almost 2000 bags and 150 boxes with parts and soldering almost 700 connections I have finally reached the end and all of you get to enjoy your new printer. I will be away from the 16th until the 22nd and will have limited internet access to give support. Please bare with me during this time and I will do my best to help everyone as quickly as possible.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com3tag:blogger.com,1999:blog-3585609270014344483.post-28962458604630592992012-07-14T02:15:00.000-07:002012-07-14T02:15:49.478-07:00Tantillus parts are starting to arriveParts have been arriving all week to fill the Indiegogo Tantillus campaign(s).<br />

</div><div class="separator" style="clear: both; text-align: left;">There have been a few delays getting some of the components due to back orders of supposedly in-stock items like the powers supplies. I have been assured that they are being shipped priority express at the beginning of next week. The few metric parts in the kit (M3 x 10 and 8mm drill rods) have also proven hard to get here in Canada in the quantities required and are the last of the hardware components to arrive. We should still be on schedule to have all of the orders from the first Indiegogo campaign shipped by the end of the month. The ones from the Maker Faire extension should only be a short time later.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">I will be contacting everyone in the next week to arrange shipping now that I can properly weigh and measure the kits. If you have purchased a hardware only kit and not informed me of which kit you would like (laser cut or printed case) please contact me as soon as possible so we can be sure to get you the correct length smooth rods and the bolts for the printed case.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">I will be trying to give you more updates over the next two weeks now that things are here and we are in the final stages of production.</div><div class="separator" style="clear: both; text-align: left;"><br />

This means setting up reasonable speeds to allow almost any geometry to print successfully without the intervention of the user to tweak settings based on the model. This includes sane retract lengths and speeds to allow small parts to print without lumps or ooze which was not always easy with a bowden cable type machine. This issue is far less of an issue today as it was 1 year ago due to the developments in hotend design and software (firmware and slicing). The J-head hotend used on Tantillus requires a lot of pressure to extrude which allows us to use retract to simply lower the pressure enough that it is below the pressure required to print but still high enough that we do not have lag when we begin to print again after retraction. The first few profiles are almost complete and will be posted soon but I thought I would share with you some of the results.<br />

</div>Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com0tag:blogger.com,1999:blog-3585609270014344483.post-29320969512628971902012-05-24T02:11:00.003-07:002012-05-25T00:02:49.492-07:00Cable driveI just wanted to quickly let you know a little more about the cable drive. I know some people are unsure of its abilities so let me put those worries to rest.<br />
<br />
The reason I went this route was to create a system that does not require special belts that are unavailable in the retail world for the most part. I also wanted to eliminate the problems found with belt driven systems like backlash from the rubber compressing or bumps from the teeth going over the idler pulley. This lead me to a cable drive system like found on a plotter or scanner. Growing up in the marine world I was familiar with roll-on roll-off winches and hoists so I knew the system could apply a lot of force and would not slip.<br />
<br />
A lot of people have asked how it works and I have tried to explain in the instructions on Tantillus.org but it will only be clear once I make the videos during the assembly of the machines from the Indiegogo campaign. I will try and explain it here as well.<br />
<br />
The two rods with the drive gears on them have holes drilled at each end to allow the cable to pass through them. The cable is then wrapped 5 times on either side of the hole in opposite directions to allow it to roll-on and roll-off but only up until the fixed point where the hole is drilled. This fixed point is what makes the system solid and prevents any slippage. We are only actually un-wrapping the cable 2 wraps in either direction and the other three on each side are to further give traction to the cable and creates an offset in the two lines that allow the cable to pass by the X/Y end. We then need to wrap the cable around the rod on the opposite side (idler side) 7-10 times to get the offset on that side as well so it lines up correctly. Then one of the cables goes through the X/Y end and through a loop in the other end of the cable and back through the X/Y end. This allows you to simply pull the end of the cable and it cinches tight. You only have to tighten the one bolt in the X/Y end to secure it. This makes it easy to align the bars as you just undo the one bolt and move the X/Y end which has the cable running through it and then re-tighten the bolt when square.<br />
<br />
The cable I have chosen to supply with the kits on Idiegogo is a braided high test fishing line from "Power Pro" and is made of 100% spectra fibre. I did some testing with wire rope and it should work but I have not done enough testing to make any solid conclusions as it may fatigue over time. But for those of you wishing to try it is usually called stainless leader line and is sold in some fishing stores.<br />
<br />
The spectra fibre is incredibly strong, but why should you believe me. This is what the manufacture Honeywell says about the fibre.<br />
<br />
<span style="font-size: small;"><i>"Pound-for-pound, it is 15 times stronger than steel, more durable than polyester and has a specific strength that is 40 percent greater than aramid fiber. Polyethylene is a remarkably durable plastic, and scientists at Honeywell have captured the tremendous natural strength in the molecular backbone of this everyday plastic to create one of the world's strongest and lightest fibers. <br />
<br />
It also exhibits high resistance to chemicals, water, and ultraviolet light. It has excellent vibration damping, flex fatigue and internal fiber-friction characteristics, and Spectra fiber's low dielectric constant makes it virtually transparent to radar.</i> <i><br />
<br />
Spectra fiber is used in numerous high-performance applications, including police and military ballistic-resistant vests, helmets and armored vehicles, as well as sailcloth, fishing lines, marine cordage, lifting slings, and cut-resistant gloves and apparel. Honeywell also converts Spectra fiber into the Spectra Shield family of specialty composites for armor and other applications."</i></span> <br />
<br />
These properties have lead to Tantillus having no detectable backlash and very accurate steps per mm. Giving Tantillus amazing layer alignment as seen here.<br />

I was planning on being at this point a long time ago. But as with most projects there have been hurdles to overcome.<br />
<br />
To be able to spend the amount of time I would like in the development of RepRap related designs and stuff to be printed I have decided to open a store to sell Tantillus parts, kits and machines. To kick things off I've decided to go with an <a href="http://www.indiegogo.com/tantillus" target="_blank">Indiegogo flexible funding campaign</a> with perks from $15 to $2000.<br />
<br />
On to the update......<br />
<br />
Introducing the Laser cut acrylic edition of Tantillus. It uses the exact same axis parts and electronics as the fully printed version. The hardware requirements are less than that of the Printed version as the Laser cut case does not require any bolts to assemble. It measures 10mm wider and deeper than the printed version while standing the same height. It has additional cutouts for a 16 x 2 LCD, rotary encoder and barrel connector for the power. It has mounting holes for Arduino mega based electronics (RAMPS) as well as Sanguinololu.<br />

This is the version available through the Indiegogo campaign and being released to the community.<br />

In addition to designing, building and testing I have also been busy building a dedicated website for Tantillus with what is (will be) the best documented instructions in the RepRap community. I have also created a <a href="https://github.com/Intrinsically-Sublime/Marlin" target="_blank">custom branch of Marlin</a> just for Tantillus with many special features like: Automatic fan control, LCD backlight control, Better support for 16 x 2 LCD, "Easy load" for loading and unloading the filament on bowden cable machines from the LCD as well as many other features.<br />
<br />
I have decided to release the files under the GPLv3 in the true spirit of opensource and the RepRap project. To do so I have created a <a href="https://github.com/Intrinsically-Sublime/Tantillus" target="_blank">Github repo for Tantillus</a> and uploaded the printable case files for those of you who would like to get a head start on printing the case. The rest of the files will be released (including source files) the day the Indiegogo campaign ends.<br />
<br />

Thanks to the kindness of fellow RepRapper <a href="http://johnbiehler.com/">John Biehler</a> who loaned me an Arduino mega 2560 I am back at development and tuning. <br />
<br />
<div style="text-align: left;">After connecting Johns Arduino I proceeded to try printing the large Yoda I had fail time and time again using my 1280 and Marlin. To my surprise it made it far past the point at which it had been failing when I realized I did not have enough filament to finish. Expecting to have a communication error and not wanting to waste new filament I started inserting short lengths of various PLA I had lying around into the extruder one after another. The result was a large rainbow yoda.</div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgGdpUwUbi6IPIJsL-toqkW0ysopGREhnWCBZTHG4ZvqPwmAB2XvbNZ6TiXuoSZLEXE0VEIqef7B6w2DiGx9_Ss68UNvPcD3mwxszGBzHeE6sJ-dMlGby326qGIv9QAyeHAJghWajkIQPk/s1600/CIMG0992.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgGdpUwUbi6IPIJsL-toqkW0ysopGREhnWCBZTHG4ZvqPwmAB2XvbNZ6TiXuoSZLEXE0VEIqef7B6w2DiGx9_Ss68UNvPcD3mwxszGBzHeE6sJ-dMlGby326qGIv9QAyeHAJghWajkIQPk/s320/CIMG0992.JPG" width="320" /></a></div>I then proceeded to load more filament into the machine and started the print over.<br />

As usual I started with Teacup and every print finished but the machine was noisy at the speeds I want to print at. The results were not exactly what I wanted either, but none the less still good.<br />

The next two and Yoda were printed with the new hotend and Teacup. I then decide to make the switch to Marlin which resulted in excellent quality prints and the machine sounded much better. But as you can see I could not complete a single build because of the communication errors. I posted a thread on the <a href="http://forums.reprap.org/read.php?146,119842">RepRap forum</a> about it but no one has responded yet. While waiting to find a solution to the serial error I decided to try hooking up my DIY sd card reader (<a href="http://uanr.com/sdfloppy/">card slot</a> and <a href="http://www.embedds.com/wp-content/uploads/2008/07/schematicuo7.jpg">schematic</a>) which went terribly wrong. The first symptom appeared when the temp would read 266 so I swapped the hotend and bed thermistors in the firmware and was getting good readings again. But the Y axis and Z axis only moved at about 10% of the speed requested and only move half the distance. I have removed the SDreader and checked all the connection points and there are no shorts or loose connections so it looks like my arduino mega is done. This is going to set the project back until I can sell another set of Prusa parts to raise the money to continue.<br />
<br />
Here's a video of the fourth print it ever did. First with the new hotend.<br />

The motors arrived today and I spent the evening wiring Tantillus up with the R.A.M.P.S. 1.2 from my RepStrap Huxley. The gears on the X and Y are a little noisy because of the textured surface of the prints but I believe they will quite down as soon as they wear in a little more. The video is of test routine I wrote to break in the gears a little and is running at 150mm/s. I ran it for about 10 minutes before I got bored and tired. The only issue I found while trying to print was the fact I printed the carriage in PLA and have no cooling on the hotend. I will be redesigning it and print it out of ABS. Stay tuned for more details.<br />

I should have the motors by the end of this week / beginning of next and will upload a proper video (in focus and lit). And hopefully the first videos of it printing.<br />

Just a quick update as some of you may have already seen via <a href="http://johnbiehler.com/2012/02/07/reprappers-of-the-world-unite/">John Biehlers Blog</a> I have been working on a mini Ultimaker style printer with the goal of making a truly portable printer. This came about after taking my Prusa on holidays and finding it too big to travel with and not required for most things you would print on the go. <br />

<br />
A few notes on its design and construction.<br />
<br />
Outer dimensions:<br />
200mm x 200mm x 300mm (225mm x 225mm x 300mm with reinforcements brackets installed, see picture)<br />
<br />
Build Area:<br />
102mm x 102mm x 120mm (100mm x 100mm x 110 usable)<br />
<br />
Features:<br />
LM8uu linear bearings on all axis (currently using Triffid Hunters printable LM8uu's for testing with excellent results).<br />
Fully printed case (12 main sections, 12 connectors, 14 axis parts, 5 optional reinforcements, 3 piece custom extruder).<br />
It can print all of its own parts.<br />
Designed to use J-head hotend (eventually).<br />
Internally mounted extruder with bowden cable.<br />
External power supply to allow for battery operated use.<br />
Uses low cost wire rope (fishing wire) or High test Braided fishing line instead of costly belts (It wraps 5 times around the rod and then goes through a hole and wraps an additional 5 times resulting in no slip). This is a roll on roll off system with a fixed anchor in the middle.<br />
<br />
Planned additions: <br />
Extension panels to allow it to expand itself by 100mm in any or all directions (incomplete as of yet). <br />
The ability to daisy chain two machines together to mass produce parts while only using one set of electronics (both machines would produce the same parts at the same time).<br />
<br />
Vitamin list:<br />
11- 608 bearings<br />
10 - LM8uu's or 8 - LM8uu's & 4 - LM8Suu's<br />
2m - 8mm smooth rod<br />
250mm - 6mm threaded rod (1/4" threaded rod) and two nuts<br />
60 - Socket head screws (Allen head)<br />
4 - Nema 17's ( Nema 11's / Nema 14's should also work as it takes very little torque)<br />
Your favorite electronics.<br />
<br />
Thanks go to John for his beautiful picture.<br />
<br />
Update:<br />
It now has a name "Tantillus"<br />

<br>
<br>
I've seen more and more people starting to use teacup and they really have no where to start. I had been successfully using SF39 with teacup for a few weeks until one of my Pololu drivers decided to release the magic smoke. I was planning on writing this up after more calibration, but that may be a while.<br>

ReplicatorG crashes mid way through a lot of builds still, just need to find the culprit for the lock ups and we will have a good working tool chain. I will post soon with a complete profile and instructions to get repG and teacup communicating.<br>

I started with a stainless steel wine glass, a stainless steel chutney dish, high pressure duel stage computer fan, and a few small pieces of tubing.<br />

</tbody></table>When I purchased the S/S wine glasses (2) I had no idea what I would build. But soon after I came up with a plan. A jet engine, well a fan jet at least. I began by designing a flame tube. This is the most critical part of the build, it needs to create a cone shaped flame inside of the combustion chamber.<br />

<tr><td class="tr-caption" style="text-align: center;">Flame tube mock-up.</td></tr>
</tbody></table>After lots of research this is the design I came up with.<br />
36 - 0.09375 holes = 0.24837890625 = 32%<br />
12 - 0.125 holes =0.151875 = 19%<br />
10 - 0.21875 holes = 0.3756347665625 = 48%<br />
The total is 99% of the flame tubes flow.<br />
I then proceeded to make the flame tube out of 0.875 S/S tube and capping the end. Once finished I cut the stem end off the wine glass leaving a 0.875 hole for the flame tube to be installed. And then welded the flame tube into the opening and drilled a 0.25" hole for the fuel tube in the capped end. I then began work on the fan side. Taking a S/S chutney dish from the dollar store I removed the bottom and welded the dish over the open end of the wine glass. To create a thermal break I used High Temp Copper Silicone to attach the fan mount tube inside of the chutney dish.<br />

</tbody></table>As you can see I cut and narrowed the output nozzle slightly. You can also see how the fuel tube entering the engine. What you don't see is how the tube bends 90degrees and enter the flame tube.<br />
<br />
I have run the engine on butane and 5-12v dc and it produces enough thrust to move itself . I then made a smaller nozzle out of a vinegar dispenser lid and it increased the thrust a little. I did at that point start to make a thrust augmenter but never finished it. Maybe some day I will build something with the engine.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com0tag:blogger.com,1999:blog-3585609270014344483.post-64346446026493166742010-11-08T22:02:00.000-08:002010-11-08T22:11:56.838-08:00Pencil Gun Video<div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: left;">Thingiverse user Parkolay has printed two pencil guns and has sent me a video for all to see.

From their experiences it is clear the choice of elastics is very important. The outer two elastics can not be to strong or they will over come the trigger friction and inner elastic. You may be able to use as strong of elastic as you want but the inner elastic will have to be very strong and may make the trigger hard to pull.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com0tag:blogger.com,1999:blog-3585609270014344483.post-89146171695449898192010-11-05T11:50:00.000-07:002010-11-05T15:09:02.836-07:00Pencil Gun Trigger Detail<div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dz8RN4fPhousKq2wiUPT6EzqlruUBUCu7b8QGJnrMYOf95DSlQSQsHyVdCBBitkH0gR5KIqZLmo08-97HFydg' class='b-hbp-video b-uploaded' frameborder='0'></iframe></div>Close up view of my pencil guns trigger mechanism.

I designed this with the little pencils you get from Ikea and golfing in mind as the ammo. The barrel has a minimum diameter of 11mm and most pencils are 7mm's giving it lots of clearance.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com0tag:blogger.com,1999:blog-3585609270014344483.post-80494334524998212202010-10-26T13:30:00.000-07:002010-10-26T17:38:12.589-07:003D view of modular printable airplane<div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dy7NhINeb6cMNSRQ-0Vpl_vsDAvwp3YVSwP3gU3dVV4DTbaXw3Nie6CUeHxtJ5zSiirzR1Nnvu0ae9-tODw5Q' class='b-hbp-video b-uploaded' frameborder='0'></iframe></div>I have spent the best part of the last month learning Blender and 3D modelling. And I feel as if I have reached the point where I can move on to the next aspect of 3D printing.On the software side of it, I still have to learn the slicing software and decide which one of the three (RepSnapper, RepRaps Software, or Skeinforge) I will use. I've installed all three on my laptop and run all of them, Repsnapper seems the cleanest and easiest but does not seem to slice as well as the RepRap software. Skeinforge on the other hand sounds to be what everyone is using but after opening it 10 times I still have no idea how to use it. It almost seems alien in its layout and wording. If anyone can point me in the right direction on which one to use and how to use it (maybe a link to a tutorial) , I would be grateful.<br />
<br />
On the hardware side of it I am still waiting for parts.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com3tag:blogger.com,1999:blog-3585609270014344483.post-85921921428223602772010-10-25T00:36:00.000-07:002010-10-25T00:36:14.603-07:00Micro printable crossbow animation<div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dwAj4bycl7pEUe1mYsIhU8QavvkMKwSBNjAa1onmqwBN36gcntvcLsKLryZNznlsyvdKNqVH062rsInABaP' class='b-hbp-video b-uploaded' frameborder='0'></iframe></div><br />

I decided to enter <a href="http://www.thingiverse.com/thing:4527">Thingiverse</a>'s rubber band contest today so I designed this crossbow. It has lots of overhangs, nothing under 45 degrees so they should all print.<br />
<br />
I have now been learning Blender and 3D modelling for 30 days and have created five projects so far.All are posted on <a href="http://www.thingiverse.com/Sublime/things">Thingiverse</a> after doing 2 tutorials from Blendercookie.com and 1 from rab3d.com and a bit of reading. My impressions of Blender are positive but it is not all that intuitive, I do have the advantage of not being trained in any other 3D programs and do not have to relearn what seem like odd short cuts. I have had a lot oh no moments, when I've pressed a key while the mouse was over a different panel making it a different function and not knowing what I had done, but all and all as long as you save after doing anything right you can model anything. The hardest part right now with Blender 2.54 is the face normals being inside out, then the recalculate doesn't correct them properly, so I have to correct them manually.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com0tag:blogger.com,1999:blog-3585609270014344483.post-53763564771241212642010-10-23T16:07:00.000-07:002010-10-23T16:31:05.659-07:00Mini printable lathe animation<div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dxbLGqlAKWQZrizW8PU2mL-pATWToDR7AMa1exeA2gH-vxILqUzeyGhngswd04_Wric6MJbQNz2L12MA5oMBg' class='b-hbp-video b-uploaded' frameborder='0'></iframe></div>A video rendering of my <a href="http://www.thingiverse.com/thing:4322">mini printable lathe</a>.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com0tag:blogger.com,1999:blog-3585609270014344483.post-83544946787020629872010-10-22T21:32:00.000-07:002010-10-22T21:32:06.242-07:00In the beginning there was nothing and man said let there be stuff.<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgw9Asc1BQv8VFWp2Yz3MBbZZHAl1g_vIUbRcYjSVbuv7tcHc67vF-V5UzvTahF67rheNtAKt16Zf-yejczxpDqCe40rLPGCD2YgeJI0ABCgBH4_vJvfdNlOlGNKJoYbxCF3wKR8PpBSig/s1600/DSC00012.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgw9Asc1BQv8VFWp2Yz3MBbZZHAl1g_vIUbRcYjSVbuv7tcHc67vF-V5UzvTahF67rheNtAKt16Zf-yejczxpDqCe40rLPGCD2YgeJI0ABCgBH4_vJvfdNlOlGNKJoYbxCF3wKR8PpBSig/s320/DSC00012.JPG" width="320" /></a></div><br />
I've started this blog to cover the progress of my Rep-Strap Huxley/Mendel. I will also be covering my 3D modelling experiences with blender and other inventions and fun stuff. My Huxley is built from wood and polyester resin using the mini Mendel/Huxley design but only 20% smaller then a Mendel. I've utilised three nema 17 1.8 degree stepper motors salvaged from dot matrix printers as well as the chrome plated guides and bushings. At the time of this posting it is in need of a thermistor, end stops, and testing.Sublimehttp://www.blogger.com/profile/17981768588609934835noreply@blogger.com2
