Having recently purchased Prism I am very happy with most of its capabilities so far (especially the excellent autofocus routine). However, I am having difficulty getting the guiding function to calibrate. I have tried many times with no luck. Each attempt has resulted in a series of vectors that do not remotely resemble a parallelogram. The failure messages that accompany each try have suggested that I increase the guide speed and/or the wait times. I have done both, with wait times ranging from two seconds to sixty seconds. I have adjusted the gear mesh of the mount and seem to have somewhat less backlash now, though I think due to the design of the mount there will always be considerable backlash remaining.
I am obviously doing something wrong. Any suggestions would be welcome.
Mount: Losmandy GM8/Gemini 2
OTA: Explore Scientific ED-127
Guide Scope: Orion 50mm 162fl
Guide Camera: ASI 1600MM
Process Controller: laptop/w Windows 10. Cnx to mount via hardwired ethernet

please provide some screenshots of your guider settings and the calibration output image showing the parallelogram. Thanks

from the looks of it, one of these axes is reversed. I say this because you are supposed to come back to the original location. Let me investigate a little further.

I had some errors this weekend that looked alot like this, any followups @Hamza Touhami ?
edit: I tore down my cem60 and tightened up the gear meshing adjustments per a document the manufacturer gave to some folks, today's crumby polar alignment and guiding calibration was pretty much a trapezoid - so it looks like ra play was big and I just never really noticed it's significance.
