|
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 2.1.0
|
|
// EBB-Command-Referenc, 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.
|
|
|
|
/* TODOs:
|
|
1 collision control via penMin/penMax
|
|
2 implement homing sequence via microswitch or optical device
|
|
3 implement hardware-button , EGGBOT-Guys call it "PRG-Button"
|
|
4 Replace Stepper Control ACCELSTEPPER --> DDS, interruptbased control to improve step-precision and smoothness.
