General Mach Discussion / Re: Mach3 turn threading problem with Z feedrate
« on: February 13, 2020, 07:51:18 AM »
Christian,
- Are you using current reduction on the drives?
1. I would suggest that you make sure that the current setting is correct for the steppers that you are using.
2. Set drive SW4 to ON.
3. Test axis motion with steps per resolution seting of 2000 .(ie; need to set SW5,6,7,8)
Mach configuration:
1. Tune the the steppers for velocity and acceleration and make sure the steps per unit are correct.
2. Notice you are using Backlash for the Z axis. That SUCKS for threading! Test the axis motion with it
off. ( .15 mm = .006" backlash )
You have no backlash in the x axis?
3. Can you set your set the spindle speed manualy?
Mach3 and spindle control may be "fighting each other" for control of the feedrate during thread
cycle.
