I've upgraded my board to SKR1.4 turbo with RepRap firmware. Heated bed and heated nozzle work, but motors do not move. OctoPrint reports them as 'no-driver-detected'.
Send: M122 ... Recv: Driver 0: position 67347, no-driver-detected Recv: Driver 1: position 67347, no-driver-detected Recv: Driver 2: position 67347, no-driver-detected Recv: Driver 3: position 0, no-driver-detected ...
I tried to figure out what is wrong, but did not find good documentation for this combination of hardware.
This is how I setup the drivers.
- I removed all four jumpers from the board below each driver (MS0, MS1, MS2, RST).
- Plugged each driver to the board making sure that the corresponding pins match (GND to GND etc.)
- Checked voltage between ground pin of the board and VREF pin of the driver. The voltage was 1.365 V (same for each driver). This is a bit higher than some guides suggest, but the drivers worked perfectly with the old board.
Some guides suggest modifying driver timings if the motors do not move, but I was unable to find the right timings for my drivers. What could be wrong in my setup?
