How did you get the calibration going through Ekos. If I get all equipment connected then the sct focuser gives min max values of 0 and the calibration does not work.

I guess I'm a bit late, sorry ...
Anyway, as others have pointed out, I use the celestron_sct drivers, which means connecting a usb cable from the focuser directly to the PC, not through the handcontroller. When doing that, I get this INDI configuration window (in any INDI client program, like ccdciel, indistarter, ekos, etc...)
There's a button "calibrate" to activate the whole process. The button is still there in the latest INDI version (1.8.4), although I have't clicked it recently, since my focuser is still calibrated. But back when I did, I remember it solved my min-max limits being 0.
