General Mach Discussion / Lathe speed control
« on: January 13, 2008, 05:05:26 PM »
I have a viceroy lathe that I have converted for Mach and it works very well but spindle speed is still manual.
The speed control is by a variable speed pully that is driven by a motor with an up and down button that changes the ivariable pully drive.
The question is if I put 2 relays driven by 2 output port bits across the up/down button is there a way to get mach to adjust the speed
to the speed given in the S command and monitor the spindle feed back to make it match the required speed ?
Thanks
