FYI, I'm using a KFlop board and Mach3.
I noticed as I'm fine tuning my mill that some of the features that I was looking forward to using in Mach3 don't work with dual motors on a gantry.
The two that I've stumbled across so far are:
1) Goto Zero - Only drives the X-axis, not the A-axis which is where my X-axis slave is.
2) The Axis Calibration on the Settings page. Again, only drives the X-axis.
Without encoders for position feedback, you can literally rip you machine in half if not careful. Thank goodness for E-stops! Encoders will be coming very soon.
I'm not sure if there's anything I can change to make these work or if that's just the way it goes.
Any input is appreciated.
Thanks,
Dennis
