Hi,
I have the top left board and when trying to get the tool sensor to work the Y Axis turns magenta.
It’s setup on the right pin but how do I map it in cnc usb controller program?
Regards,
Jasper

Hi, Is your Y axis connected to the Y axis output?…if your Y axis turns magenta, what is the tool sensor doing? – where is it plugged into?……which USB CNC controller program are you using!…..

Hi,
The Y axis is connected to the Y axis on the board, It mills fine.
When i tap the alligator clip to the block nothing happens with the Y axis or the Z axis.
They just keep going and don’t set to 0
