Hey all,
I just installed the VistaCNC iMach 3 Spindle Tach (info here) and I'm having an odd problem. When the spindle tach is plugged in, there is no readout in the RPM DRO and the spindle speed override fluctuates by itself, causing the spindle speed to increase and decrease wildly. When the tach USB is unplugged, everything behaves normally.
Anyone else ever encountered this problem? Any advice? I need to (a) make the tach stop controlling the spindle speed - it should only observe the actual speed, and (b) make the true speed appear in the RPM DRO.
I'm using Mach3 with the standard 1024 screenset and a Novakon NM-145 mill if that helps.
Thanks!
