So I have just about had it with my EQ6-R Pro... This is my 3rd one, because I had to return the other two due to tracking issues (for example, when I would try to park the mount, the RA would freeze). I had better luck with my AVX Mount.
With my new EQ6-R Pro, I am directly connected to my PC (no hand controller), with an ASI1600mm Pro (w/ filter wheel) and a ES ED80 Triplet APO Refractor attached. I use a side-by-side set up with my ZWO 60mm guide scope. It should be well below the weight limit.
My issues started happening when I was getting unbearable backlash during dithering, where it would take almost 2 minutes to recover. I never solved that issue before I moved to a new home, and put everything away for the last few months. I noticed then that the axes have more resistance than I would expect for a $1600 mount, but I couldn't confirm that was the problem, and I am not very handy and somewhat new to this stuff.
I got it out again, and the first night it worked absolutely incredible, no issues. Everything ran as smooth as possible.
However, last night, while I was trying to plate solve, the mount would not move closer to the object once it got so close. I moved over to PHD2 to look at the live view from my guide camera, and noticed that the mount stopped tracking. I tried again, same thing, and I tried to guide and found it was the RA axis that was not tracking (from the huge dip in guiding). There were no errors on EQMod. It worked randomly throughout the night, and it happened every time I tried to do a plate solve (but I can't be certain that is the only time it does it).
I tried to fix it by disconnecting the mount and restarting, and noticed that when I parked the mount to the home position, the home position would be off by a couple of degrees, sometimes even more.
I thought maybe it was a periodic error issue or something, but it started working again like 2 hours after fiddling with it and trying different USB ports, different power sources, etc. When it finally did work, I did only one plate solve, and just hit guide, and it worked fine for the rest of the night. Tonight, I tried again and it was doing the same thing, and I noticed it mostly does it when I try to do a second plate solve.
I have been looking everywhere for a solution... Could it be a software issue? In my research, I found you are supposed to have the bits per second rate in the port settings set to 9600, but mine only works at 115200. Could that be causing the issue? Should I reinstall everything?
It really sucks that I invest so much money to have a better mount and less headaches, but I have more... I am going on a camping trip next week, so I am hoping to fix it before then... Any ideas, and I will be forever grateful.
