Re: Mach1 Unable to Find Home Position Suddenly

Can you screenshot the AP ASCOM driver window with it fully-expanded, right after SGP launches it and it connects to the mount, and post it here?

Also make a screenshot of the Telescope tab in SGP's Equipment Manager.

Can you please tell what exactly you did, how you commanded the mount to move without a planetarium program?

• Power on
• Start SG Pro
• In SG Pro connect mount
• This brings up the AP V2
• in AP V2 unpark, from last selected (as this was from the last night, the mount was correctly parked with alignment lines nicely matching)
• Slew the mount using the AP V2's driver to a random NW or NE direction until the Ra axes was almost parallel
• Asked AP V2 to park the mount, park #3
• Watched the mount miss the Ra line by about 1/4"
• Loose the clutches (sometimes didn't do that) and manually moved the Ra axes so that the alignment lines match
• Unconnected the mount in SG Pro
• Unhooked the power cord from Mach1
• Hooked the power back on to Mach1
• In SG Pro reconnect the mount again
• Started from #4 again with the same result every time, the mount misses the mark by about 1/4" (missed side depending on which way the slew was as said in the previous post)
