Do you cut a lot of threads with this configuration?
I was under the impression that the chain and the gears that interconnect the spindle to the feed screw.
It seems to me that if you gut the drive train you would need to rig a sensor on your spindle and allow the computer to control the spindle speed through your VSD. Mach3 would then be able to cut threads under CNC control.
Are you doing this?
How well does it work?
Have you used it for both fine (~40 tpi) and coarse (~4 tpi) threads?
Do you miss the manual threading capability?
