OK Rant here:
I bought the UC100 years ago, couldn't get the backlash comp working good enough for MACH3, switched back to parallel port.
Finally put together a WIN10 PC for Mill, put MACH3 back on it with UC100, the servo spindle is not getting full RPM that's set in MACH3, suspect it's not running at 100mhz like advertised. Added more reduction to the servo driver (less pulses per rev) RPM now accurate. Still have the wonky backlash comp, lets try UCCNC software. What a fucking mistake!!!!
So now I have the UCCNC software running, after spending hours getting everything working as it was with MACH3, Y axis only moves to +, dead -. Now this is after screwing around for hours with machine without that problem (other wonky problems). Check wiring, check the motor. Swapped pins in setting from the X axis to the Y axis, Y works fine now, problem moves to the X axis. OK must be the BOB. Switched out the BOB, WTF same problem. So now I switch back to MACH3 with the UC100, everything works fine. Reloaded UCCNC, same shit. OK DONE with this CRAP!!!!
Besides the learning curve from MACH3 to UCCNC and just the wonky ways they do things, what a FUCKING WASTE OF MONEY!!!! Also false advertising that the UC100 runs at 100mhz, it doesn't with MACH3, it seems to with UCCNC. Wonky like the backlash comp, jitters all over the place no matter what the backlash acceleration is set for. I read somewhere you have to slow the speed down for jog when in step mode? Another bug that hasn't been fixed.
I never thought I would find a less stable platform than MACH3, I have, UCCNC, what junk...
