It actually isn't too bad, but the Creator Pro has a more solid Z axis and platform. Really, that so far is my only concern, but it is a big one because of how flexible the guide rods are. It is silly how easy it is to move the build plate from side to side especially when the platform is in the middle of the travel. I'm not too fond of the metal side plates, but I suppose they will be ok.
Note also that flashforge extruders and thermocouple will not fit the Qidi. The Qidi uses a slightly bigger diameter thermal barrier, and the thermocouple has 5mm threads instead of the 4mm threads on the Flashforge.

Thanks, yes, the bed is the biggest problem I see, too. I'm playing around with that this weekend. I doubt I'll find an easy solution but maybe there's something to be done there. Despite its flimsiness it seems to hold level for a very long time and the ringing on direction changes isn't bad and can be dialed down with software. Hoping to try some hardware solutions.

Yes, I have parts ordered, Enough to make 4 kits for now to test. The platform is 5mm solid carbon fiber plate. I have moved the adjusters to the corners of the plate to remove the teetering, It uses 10mm bearings. I might switch to 12mm rods and bearings, but 10 should be good. I will have it in two flavors. One where the buyer prints their own top and bottom mount and one where I will supply it. At least that is the plan for now.

I have a Qidi bought around Nov. 1, 2015 and it has 4mm thermocouples. They went to the larger thermocouples last december in there latest update. They seem to roll in improvements to the machine several times a year.
I don't really think the thermocouples being a different size makes much difference unless you have multiple machines with the smaller size.
Also check Qidi ebay store there parts can be bought at ridiculously low prices that Flashforge will never match.

Part of the problem with the Z axis is how weak the rods are intstalled in the bottom mounts. The Flashforge plastic mounts are stiffer and more material around the rods, even back when they used 8mm rods...
On the Qidi, it might be possible to use a solid resin based epoxy and fill in the cups a the bottom of the z rods. This will help stabilize them. Right now they are like a fence post in a hole that hasn't been filled in.

I tried a less permanent version (see photo - there is a mirror version on the other side). It makes some improvement in ringing on a box test structure, so I think further improvements with either a better printed part than my sketch, epoxy or a redesign will help.
