Hello guys. I have a question about my Baader SteelDrive and SteelTrack NT. When I extend the focuser to its maximum position using the software, instead of coming out 40.020mm it only comes out around 35mm. Does that mean the step size is wrong and I need to make some measurements and change the step size?
