|
Thanks for the nice libs ACCELSTEPPER and SERIALCOMMAND, which made this project much easier.
|
|
Thanks to the Eggbot-Team for such a funny and enjoable concept!
|
|
Thanks to my wife and my daughter for their patience. :-)

// EBB-Command-Reference, I sourced from: http://www.schmalzhaus.com/EBB/EBBCommands.html

// no homing sequence, switch-on position of pen will be taken as reference point.
|
|
// No collision-detection!!
|
|
// Supported Servos: I do not know, I use Arduino Servo Lib with TG9e- standard servo.
|
|
// Note: Maximum-Speed in Inkscape is 1000 Steps/s. You could enter more, but then Pythonscript sends nonsense.
|
|
// EBB-Coordinates are coming in for 16th-Microstepmode. The Coordinate-Transforms are done in weired integer-math. Be careful, when you diecide to modify settings.

/* TODOs:
|
|
1 collision control via penMin/penMax
|
|
2 implement homing sequence via microswitch or optical device
