I can not calibrate and guide with my ASIAir/ AM5. This only started happening yesterday.The only equipment that was changed was the 'main' scope.
Equipment= 30 mm SVbony/ ASI120MM connected to an ASIAir Mini on an AM5 mount.
Dec duration = 1900, max RA/ DEC pulse is 150.
When I initiate calibration, it goes fine in the initial (west) direction and reaches 25 and 20 steps. When it reverses, the amount moved back with each step decreases and then reverses so that east step 0, instead of being 0, is back to 25. Roughly the same happens North / South. Attached is a screen shot of my PhD2 tracking window. As you can see, RA and Dec are not at 90 degrees to each other and I can never correct enough to guide. Has anyone seen anything like this before?
