This of course means I run out of steps and it has to nudge south 4 or 5 times. Occasionally it tells me I have backlash issues but not always.
When I start guiding everything goes well, corrections are made, after a while and then the mount drifts south because the north corrections are not doing anything at the mount. PHD is sending corrections but the mount seems to do nothing, sometimes it works again for a while other times it just bugs out.
I have tried the mount on battery and power, the issue does not change. I am using a Dell laptop to control the mount.
Latest syn scan app is installed.
Latest PHD2 installed.
With no guiding I can get up to 2 minute subs with round stars.
I feel no backlash in the DEC or RA
I have attached a few images, any help would be great as I am very confused.
Thanks for reading

I had the GTi - briefly - and experienced some issues similar to what you describe. When I initially contacted the retailer to talk about a possible return of the mount, I was told that the reason I was having these issues was because I wasn't guiding the mount. My argument that with this level of mount guiding shouldn't be necessary was howled down. Like you, I upgraded firmware as much as I could and checked connections, etc., but still experienced similar issues, even when I tried guiding it.
I can't offer you much in the way of advice other than you aren't alone in the issues you're experiencing. I'm aware that some people have purchased the GTi and it's worked perfectly straight out of the box; others have had endless issues, similar to what you describe, and have returned it.
I think at the bottom of it all there are some quality control issues. It sounds like you've done much the same as many others in your attempts to solve the problem though. Good Luck with it!
