Thought why not turn so screws are on front so swapped heads which of course does not work because of offset, but now can't swap back because they are now frozen in place. Tried pulling, prying, and taping for a couple of hours scratching everything pretty good and no movement, so thinking I'm screwed. Last resort before ordering new parts tried spray lube and managed to wiggle them out. Had I carefully read the whole thread it would have saved me a lot of grief.

Got everything back together and it was the same still off just a little so had to take apart and redo with calipers handy. So now I have ordered the part jfkansas designed, looks like it will make things a lot easier.
Thanks, just saw the notification pop up. I hope to have a video up on installation/use of it later this week but was busy printing misc stuff this weekend. I too had the same issue of getting the thermal barrier tubes out after the set screw leaves its mark. The set screws really gall things up. On my original flashforge parts I ended up drilling out the mounting hole a little, but this doesn't do anything for heat transfer at all since only a sliver of metal to metal contact is left after the set screw pushes the tube forward in the hole.

One of the most important things to do when putting this new system on is getting the thermal tubes nice and smooth again. This will help insure that the tubes slide up and down easily when the clamps are loosened. I have been using the system for a couple of months now with no issues. Periodically check the clamp bolt to make sure it is tight.
