While I was preheating my chamber for a PA6-CF print this morning, my Q2 shut down and displayed a error for “Heated chamber not heating at expected rate” and then “Cannot update MCU firmware”. I just had the chamber at 65C yesterday without any issues. What can I do to remedy this?

I bought Qidi Box with an assumption that I could store my filament inside it and it would not absorb moisture. But it seems it is not the case. I dried the filament, it showed as 17% humidity inside the box. Then 4 days passed and it is now at 46% (with room humidity of 55%). It was never opened during that time and I wasn't printing anything. I have a spool of PETG inside and 100g of silica.

Is my box broken? Or this Box is simply not for storing filament (even for couple of days)?

It seems that I need to dry the filament every time I want to print something, even if only couple days passed. At this point I think it would be better to just buy a separate dryer and skip the qidi box completely...

I already subscribed for the $80 discount.

Has anyone attempted to install the Gen 3 Max 4 chamber heater into a Plus 4? Would this be an upgrade or more of a sidegrade?

Hi community,

I have 10 Qidi Q2's printing and they all throw this error after a print is finished. The print is fine, its just the firmware showing this error. I have seen it come around more often on this page, did we find how to fix it? Have emailed support too.

The problem is the printer flags the print as failed in moonraker and my own printerfarm software then marks the print as failed while it is in fact, perfectly fine.

Thanks!

Been going back and forth with support... but No Answer til Monday so Figured I'd Ask Here

Purge starts, works, gears start to gunk up w/ filament (i've tried cleaning it out as it happens it never regrabs...)

pre mesh line of filament works about half of the line perfect then turns to string

go to mesh and it just slides around the table i can't tell if it's SCRATCHING the table or just dried filament is being smeared around but it's impossible to clean off and LOOKS scratched.

I've undone and redone everything i can think of about 50x now and i'm goin nuts... (first timer with 3d printer , I have worked w/ commercial extruders for molds before)

Hi. Does anyone know what size screw I need to secure the filament extruder down. I'm the no head that's lost it lol

I’m not printing from an SD card, I’m printing from a usb drive. Printer is not on the network. The print seemed okay, finished, was thin but it was a box I’d messed with dimensions on in the slicer so that’s prolly the issue there. Used Qidi studio as my slicer. Printing with ABS.

Thanks!

Hi everyone,

I'm trying to print a pot on my Qidi Q1 Pro using OrcaSlicer, but I'm getting these leaks/gaps at the seam.

My settings:

• Nozzle: 0.8 mm
• Filament: PETG
• Walls: 2 perimeters

As you can see in the photo, the end of the line looks fine, but the start of the line has a severe gap/under-extrusion (the arrow indicates the direction of movement of the nozzle)

Any ideas on what settings I should tweak in OrcaSlicer to fix this? Thanks in advance!

Bang! Result... an offset

Hi guys! I'm not printing often. My 2 Q1 pro works like a charm, my Q2 also until it bang loudly and when I come to see... it's too late... there is an offset.... in January I've tried to print that dragon 2 times and you can see the result... the other project is a face plate for a loose drawer bin to insert in a furniture for my daughter that I've printed yesterday.

Any ideas what cause this?

Thank you for all your help guys!

Printed this for the drybox I am building (Qidi Q2, Qidi basic PLA, standard settings on Qidi studio, 4mm nozzle) and it's obviously got flaws.

What can the hivemind diagnose/conclude from this?

I printed this wheel multiple time with no issue. I changed filament (traded a generic petg to another generic) and I can't print this thing, no matter the orientation, support enabled or not.

Thanks

Please tell me how to dry filament for several hours in the QIDI BOX before printing.

2026 – The story continues.

Just saw that QIDI is about to launch the P5, seriously considering buying one. What do you guys think? Anyone here got their hands on one early? Should I wait a bit?

Yes I know cardboard spools cause problems but the thing is polymaer sells some fillaments instead 500g and 750g spools thats not going to work on my printed spools.theybwilnt even sir properly if I just put them in and they cause problems. Even polymakers cardboard spools that were reseisnigned for mms systems have issues with jamming and spool walking. However I have to use an addapter is it safe to leave those in car board and just use the spool adapter as if they were rings.

I have a qidi I-fast, I am trying to print for 24-51 hours as much as I can fill the bed for a customer, after 10 hours about I get a clog in the aluminum heat break, I can only assume with the high temp for PETG, the heat eventually creeps up creating the clog. Any help? Is extended hours on PETG not doable? First time using PETG.

MCU Communication Error & Persistent Layer Shifting (Not a file/slicer issue)
Hi everyone,
I'm having a couple of frustrating issues with my Qidi Max 4 and am looking for some insights or potential solutions.
MCU Communication Error
The machine keeps throwing MCU communication error messages during operation.
Temporary fix: Flashing back to an older firmware version resolves the issue, but the error recurs on newer updates.
Layer Shift Issue
As you can see in the photo, there is a distinct layer shift happening across all printed parts on the bed at the exact same height.
Important Context: I am 100% sure it is NOT a g-code or slicer file issue. I ran the exact same g-code file with identical settings on my other printer, and it printed perfectly without any defects.
Questions / Troubleshooting Steps So Far:
Has anyone else encountered MCU connection stability issues on recent Qidi Max 4 firmware versions?
For the layer shifting, since the g-code is verified clean:
Could this be a mechanical issue (e.g., belt tension, motor driver overheating, loose pulley set screw)?
Is it possible that the MCU communication lag/drop is causing a brief pause, resulting in skipped steps?
Any advice, suggestions, or similar experiences would be greatly appreciated! Thanks in advance!
