Hello all,

I put together an autofocuser from a stepper motor, timing belt and pulley, and a bracket to mount it on top of my refractor. I'm using the Waveshare Motor HAT on my Pi 4 running StellarMate OS (1.5.1, I think).

The trouble is that the system has about 100 steps' worth of backlash when it reverses, so the accounting can get all screwed up in the Focus Module. There is a Backlash text-entry box in the Mechanics tab of the Focus Module but it's disabled.

I'm using Kevin Ross's indi_wmh_focuser module, building from source so I can modify that if I need to set something in the driver itself. Just wondered if there was an easy fix before I dive into the code.

TIA!
