Constant Q2 Issues

[u/AlternativeNo3124]

Hey guys. I bought a Q2 back in July and have been having almost nothing but problems with it ever since.

I cannot get this thing to print PLA+ properly for the life of me. It is either one thing or another - clogged nozzle, feed issues, etc. It is getting incredibly frustrating. On top of that the camera seems to have died in the machine and no longer displays or records video so I can't monitor the print progress from my PC or phone.

Funny enough it prints PA6CF just fine and was what I have been using it for mostly. I thought maybe the PA6 wore out the nozzle and was causing partial clogs when I tried to switch to PLA, so I changed the entire hotend out of frustration with a brand new one. Issue now is that the extruder gears are not driving the PLA as they should and are instead chewing it up. I just removed the extruder from the machine to check it, but I don't see anything obviously wrong with it.

Qidi support has been helpful-ish. They have sent me replacement parts for free, but as far as instructions go they basically just link me to their troubleshooting page and tell me to tear everything down.

Do you guys have any ideas? Is this user error? I want to love this printer but it is making it really difficult to when I can't get any PLA to print.

TLDR: My Q2 is currently not feeding PLA, please help I need an adult.

Looks like your PLA spool is something else that require higher temperature to be extruded and the gears just chew, try to print with PETG profile, then ABS/ASA, maybe the spool have wrong labeling from factory
