INDI focuser driver for Waveshare Stepper Motor HAT for Raspberry Pi #54647

Great! Congratulations. Glad it works out well for you now.

I guess there is some truth to the saying that having a screw loose is not a good thing after all.... :-)

Best wishes,

INDI focuser driver for Waveshare Stepper Motor HAT for Raspberry Pi #54902
Everything has been working well over a few nights of imaging with one exception. I had an (apparently) unrelated issue where I had Kstars crash on me a couple of times. Once that happens while the focuser is not at zero, I have to manually move focus back to the zero position before starting indi / Ekos again. If I don't, the focuser is at the previous focus position (say 78) but the driver now thinks its at zero and there's no way to move past the zero point. Does anybody know of any way around this? I'm not sure there is a good solution. The best I can see would be to always save the focus position and assume it hasn't moved (while also moving to zero on a clean shutdown). Support for going below zero would also help manually get out of this situation if there was then a "set as zero" option to go with it.

I was hoping the stepper driver hardware might have support for stall detection so we could use something like 3d printers use for senseless homing, but it doesn't look like it does. I suppose another option would be an actual end stop / zero switch, but that would be a good bit of extra work / hardware.

Sorry, I just now saw your post.

I use the "sync" feature for that. I just type in a large enough number (usually 5000) and hit "sync" in the focuser INDI control panel. It now things the focuser is at position 5000.
