I am having an issue with the ZWO EAF v1 and its range of focus (number of steps).
The EAF can only travel from 0 to 60000 (steps), but the Celestron focuser range is way beyond that. So if you have different image train configurations the EAF will stop before you can get to that focus point.
In steps the Celestron's range is 0 - 180000 steps.
ZWOs response to that when you get to the end of the EAF range then you need to set the EAF step count to 0 and continue on.
The issue with Ekos / INDI is there is no way that I can find to set the step count to 0 using the INDI controls or config.
I don't have an EAF focuser, but I believe the Sync button can reset the count back to 0 (if moving inward, or sync to 60000 if moving outward) so you can continue onward.
