I took the bottom off and secured the wiring better which did the trick.

I haven't installed the glass build plate yet as I'm seeing how long this stock setup lasts. I have noticed after time the prints come out with a finish that definitely needs sanding but will probably be fixed with the glass build plate setup. I wasn't very happy with the way the wiring & filament guide was hitting the acrylic cover so I made something to take care of it but prior I had used "shims" to keep it at the level I wanted.

I've designed a couple upgrades for the QIDI which I will be sharing on thingiverse. I'm sure they will fit the other printers as well, flashforge etc. If anyone is looking to add an arduino temperature/humidity sensor with LCD setup to their QIDI, I would be willing to share the plans when I finalize them as the project is almost complete. It adds a light switch to the printer as well since I found that the software didn't have that functionality. It looks like it should work according to the UI but when I pressed it, but the lights did not go off. I still have to figure out a mount for the bare DHT sensor, but that should be pretty simple.

I do have the issue of the rear Y-Axis rod being bent and I fear it is causing issues as the machine has developed a creaking when printing but it hasn't affected print quality too much from what I can tell. I greased all the rods/bearings properly with Super Lube and clean them if they accumulate too much grime but the creaking seems to be happening in the rear right corner of my machine. I will most likely contact QIDI support shortly as I just received the machine and I am willing to disassemble and correct the issue if there is a faulty bearing, etc. Video has been captured of the sound + movement in Y-Axis rod but hasn't been uploaded yet.

Overall I am really happy with the printer as I expected minor issues that could be resolved in a couple hours which has all been true so far. I fear if the Y-Axis rod bearing seizes or breaks a plastic part I will be in some more serious trouble but everything else seems stable and I am quite pleased with the out of the box printing in 3 hours experience. A lot of research was done prior and that helped me choose upgrades wisely and know what to expect from the machine for both output and maintenance. Simplify 3D has definitely worked out well for me and importing custom models and generating supports was a breeze. I found some solid settings to start with and haven't really tweaked them much since my first couple prints. I'm hoping I can improve my print quality and figure out the smoothing of ABS printed items but that is all in due time.

I have this EXACT same issue on mine. It actually got really really loud on prints that ran multiple hours. They sent me some steps to try of loosening the grub screws on the back left and right pulleys, and then moving the carriage back and forth quickly a few minutes and then tighten them down again.

It has been pretty quite since then
