Arduino Test Code

Simple tests to help debug and check your arduino and cartesian robot.

pRINToPTO - doesn't move any motors, only prints the status of the opto switches to the arduino IDE terminal.
hOMING - brings back all the axes one by one to the home position using only the opto switches as feedback (no sanity checks).
rECTANGULARsPIRAL - prints the above rectangular spiral from the current position (no homing). width height and margins are easily modifiable.
