This is the arduino code for a joystick controlled CNC plotter with infinite Y-axis. A video making-of is visible here: https://www.youtube.com/watch?v=JPHRC_p_l5g
Hardware and parts used in the project:
*Arduino Uno R3
*CNC shield v3 by protoneer: https://blog.protoneer.co.nz/arduino-cnc-shield/
*4 pololu a4988 drivers
*2 Nema 17 steppers
*1 12V solenoid
*Arduino analog joystick
*Resistors: 1k Ω
*various mechanical parts from ebay
