Hallo,
vielen Dank für die Hinweise. Da das mein erster Post ist, weiß ich natürlich noch nicht was ihr zur Hilfe benötigt.
Es klingt in der Tat so, dass der Arduino unkontrolliert Y Schritte ausgibt. Und das dauerhaft. Selbst nach 15 min hörte dieser nicht auf.
Hier der Sketch für den Arduino:
/* Eggduino-Firmware by Joachim Cerny, 2014
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.

// implemented Eggbot-Protocol-Version v13
// EBB-Command-Reference, I sourced from: EBB (EiBotBoard) - Commands
// 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
*/
//==================================================================================
// C-EGG is almost 100% EggDuino
// But since some of the Commands of the Egg-Bot Extension for Inkscape did not work
// I had to use some fixed values in the code instead.
// E.g. for the Servo Command
//
// But almost all credits go to Joachim Cerny and the Egg-Bot Team

Habe den Sketch noch mal hochgeladen. Nun scheint es zu laufen. Leider kann ich aber nicht den Pin finden, auf dem der Servo (Pen) angesteuert wird. Kann mir jemand sagen, an welchem Pin der Befehl liegt?
