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.

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 |
Teacup Configuration
----------------------------------------------------------------------------------------------------------------------/// used for G0 rapid moves and as a cap for all other feedrates
#define MAXIMUM_FEEDRATE_X 9900 // 165mm/s
#define MAXIMUM_FEEDRATE_Y 9900
#define MAXIMUM_FEEDRATE_Z 300 // 5mm/s
#define MAXIMUM_FEEDRATE_E 2000 // 33.3mm/s this is set low due to the limitation of my extruder
/// used when searching endstops and as default feedrate
#define SEARCH_FEEDRATE_X 4800 // 80mm/s
#define SEARCH_FEEDRATE_Y 4800
#define SEARCH_FEEDRATE_Z 300
// no SEARCH_FEEDRATE_E, as E can't be searched
/// this is how many steps to suck back the filament by when we stop. set to zero to disable
#define E_STARTSTOP_STEPS 10
#define ACCELERATION_STEEPNESS 250000
#define TEMP_HYSTERESIS 5
/**
Soft axis limits, in mm

*/
#define X_MIN -100.0 // 0 at center of 200
#define X_MAX 100.0
#define Y_MIN -100.0 // 0 at center of 200
#define Y_MAX 100.0
#define Z_MIN 0.0 // 0 at platform
#define Z_MAX 140.0
I printed this Prusa Mendel using these settings.
(Modified to use only one motor for the Z stage)
