Arnie,
You mentioned that you are able to thread using the existing D&M speed pickup. My unit had a single pulse-per-rev pickup on the spindle itself and a multiple pulse per rev encoder on the motor, which unit are you using for speed input to Mach3? How low of an RPM can you control the spindle speed down to, and what speed do you use to thread? I burnt up the original spindle motor controller and replaced it with another unit. I'm using the single Pulse-per-rev pickup and am having trouble controlling the spindle speed to below ~200 RPM.
Thanks,
Adam |
