Eric so sorry to hear. I dont think is a Voyager problem, because if you tried to do VCurve 10 time and 1 work i think is question of setting or focuser. Usually for 99% of times setting is ok for all user …
I think the problem is in the focuser. I write in italian how to calculate backlash:
Try to translate from italian with google translate.
Now i look inside log and i tell you i found something.
Start to put 100 step of baclash in IN, remove backlash or other compensation in focuser driver.
Not reverse nothing, just check if go lower in step the focuser go in , and if you go higher in step the focuser go out
WHen you do the first light please try to contact me, we can do togheter in remote teamviewer if you can.
All the best
Leo
