Never thought I would get myself into such a knot
Issue is that with UCCNC, UC300ETH into UB1 board, one drive connected as a test (on bench), I can't get it to move?
I'm pretty sure they should work with UCCNC as the feedback for position is handled by the controller, all UCCNC supplies is STEP / Direction.
Setup as Y axis with Step (Pin 4) and Dir (Pin 5) on port 2. Using differential connection as recommended in the UB1 manual.
Maybe it's my poor understanding of the config. UCCNC manual under Steps per unit has me a little baffled:
"Steps per Units: Which is a numeric value and means the output pulses per one Unit of mechanical
travel on the machine axis. The correct value depends on the resolution of the motor and motor
drive in case a stepper motor and drive is used or on the encoder resolution if a servo motor and
drive is used to drive the axis."
Do I treat the drive just like a regular stepper (first part above), then it would be 200 steps per (1.8 degrees), Ballscrew will be 5mm pitch. Have selected 2000 Steps/Rev per label on Drive. Therefore 2000 / 5 = 400 steps / unit. If the latter, stepper has a 1000 unit encoder.
One thing that can get some 'erratic' movement from drive is to select a lower Kernel frequency and restart UCCNC. 25 / 50 and 100 get some activity and it certainly is NOT correct. But at 400kHz - ziltch.
I'm using version 1.2047 of UCCNC.
