Hackley a Repstrap Huxley

I should start by saying I built this many months ago and I'm just trying to document it now as I've had good success with it.
 
I decided to build what had to be one of the first Repstrap Huxleys in the world and this is what I came up with.

This is my hackley called the Geometric Object Deposition Tool

Teacup and skeinforge 39, where to start.

Outdated. 


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.

Electronics.

Arduino 1280
R.A.M.P.S.

Skeinforge 39 Settings

When I refer to default skeinforge settings I mean the settings that make the boxes return to a grey background, not yellow or teal.

Section	Necessity	Current settings in my profiles
Bottom	required	Default skeinforge settings.
Carve	n/a	Infill in direction of bridge enabled and all settings to default.
Chamber	not required	Not enabled because I don't have a heated bed.
Clip	required	Clip over perimater width (ratio) set to 0.35 Others set to default.
Comb	required	Enabled because it makes for cleaner builds.
Cool	not required	Not enabled because my extruder oozes to much during cooling (needed for printing small stuff).
Dimension	required	Enabled and set to "relative extrusion distance" experiment with the setting to work with your extruder.
Export	required	Activate Export checked Do not change output File extension = gcode Rest are blank.
Fill	n/a	Default skeinforge values Activate for filled Deactivate for shell only Set Infill solidity ratio to zero for hollow
Fillet	not required	Enabled Set to Bevel Corner feed ratio of 1.5 Fillet radius of 0.7 Used to deal with blobby corners but they could be dealt with in other ways.
Home	not required	I don't use homing.
Hop	not required	Not enabled because it makes the builds take a long time due to lots of Z movements.
Inset	not required	No check boxes enabled Bridge width 1.0 Loop order ascending area Overlap removal width 0.5
Jitter	not required	Enabled and set to 2.0
Lash	not required	Not enabled
Limit	not required	Not enabled and both set to 0
Multiply	not required	Not enabled
Oozbane	not required	Not enabled (use teacups E_startstop_steps)
Outline	not required	Not enabled (I have a start.gcode that includes an outline purge which is not included so this may be a good idea).
Preface	not required	Enabled but the start and end gcode files are empty. All check boxes are unchecked except "set to mm".
Raft	required	Enabled because it is required by  temperature (DO NOT TURN THIS OFF) I have it set to produce no raft but it must still be enabled.
Reversal	not required	Not enabled
Scale	not required	Not enabled
Speed	required	Enabled both speed and flow rate. Bridge feed rate 1.2 Bridge flow rate 1.0 Duty cycle both set to 0 Feed rate 65 Flow rate 67.5 Orbital feed rate 0.5 Perimeter feed rate 0.7 Perimeter flow rate 0.8 Travel feed rate 200.0.
Splodge	not required	Not enabled
Stretch	not required	Enabled Loop stretch over perimeter width ratio 0.1 All other settings set to default
Temperature	required	Enabled and possibly set a little to high for PLA due to the thermistor location on my hotend.
Tower	not required	Not enabled
Unpause	not required	Not enabled
Widen	not required	Not enabled
Wipe	not required	Not enabled

First Prints

Finally got my printer up and running and starting printing using ReplicatorG and Teacup on an Arduino 1280 with Ramps. 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.
