General Mach Discussion / Mach Turn Spindle direction issue
« on: March 21, 2015, 07:42:45 AM »
Hi,
I’ve just finished my custom CNC lathe build and I have an issue with the spindle direction.
Everything is working ok as far as the spindle running in both directions (and variable speed control is working). But I would like to machine with a default CCW spindle direction.
Using it manually when I press the spindle start/stop button it runs CW. I can use the M4 command to change direction but I have to use it every time I press the spindle button which is a pain.
Is there a way to change the start/stop spindle screen button to an M4 CCW default setting? As my CAM software outputs an M4 CCW G-code.
Cheers
