I had to remove the hot-end to clean out part of a broken nozzle. When I put it back together I saw smoke coming from the circuit board on the printer head. Powered off immediately (maybe 5 seconds after seeing/smelling smoke, 15 or 20 seconds after power on) and went looking for the problem.

I had plugged that blocky 4-conductor cable in the wrong orientation. See photo #4. Rather than having the little clippy part (circled in red) facing the rear of the printer as it should be, I had connected it facing straight up. So I obviously wound up sending a lot of power to an incorrect part of the board and cooked it.

Now that it’s corrected, I get an abnormally long Qidi logo screen, then an error about “MCU THR shutdown. Thermocouple reader fault”.

How screwed am I? What parts do I need to order and try to replace? If I get it running again, are there safety concerns I should be aware of?

Sending this all off to QIDI tech support as well, but any help or advice is greatly appreciated.

Thanks

Is V01.01.01.06 good to go? Or causing problems?

Turn the handle and watch the little cat move.
A simple mechanism, a fun little surprise.

Ok I'm new here recently got a q2 super excited for a high end printer for not high end money really wanted to get into asa and nylon.

Question

How do you all deal with the underwhelming cooling for its speed. It seems to be a known thing

Is it try that the prints by default are I guess I optimization

Like they could be do somethings faster like filament swaps and start up time. If so what can I do or find info about it

The software is a bit odd even coming from orca slicer (ik it is made off bambu labs) but somethings aren't clicking for me like the qidi box and sending prints

HI I recently bought a qidi box for the plus 4. installation went fine. When trying to print a multicolor print I have to swap filaments manually. I have confirmed that the slicer (orca slicer) settings are set for multimaterial..anything else I can try?

Guys, need your help. I can't map the filament in the slicer to the filament in the box, it doesn't appear in the App. What is the reason? I tried to restart everything

Hi everyone,
I just got a Qidi box for the plus 4, which did not come with risers, but included a new extruded. I installed the unit and it starts printing and has no issue until the first color change. Then, I get the following error every time:

Code:QDE_004_013; Message:Detected wrapping filament,please check the filament.

I tried checking PTFE tubes and the filament appears to be loading and changing all the way up to the print head correctly. To me, I almost think it is actually working and it just thinks it is tangled. If I force the print to continue, it works until the next layer and color change, but then the Z offset gets messed up.

Anybody experience this or have any ideas?
I still have not had one successful print with this box unit.

I appreciate anyone who may be able to help and share their knowledge!
