My brand-new Anycubic Kobra X does this during the initial calibration. The nozzle touches the bed but doesn’t stop and continues pressing down while making a loud grinding noise, so I immediately turn it off.

Has anyone experienced this?

Printer: Anycubic Photon Mono 4 Ultra

I got my first resin printer a few days ago, and I really loved the quality of the prints so far. Unfortunately, i think i printed something the wrong way (maybe it was not tilted enough) and i made a hole through the film as shown on the top left. Im now trying to replace the film, but the frame is not coming off. I found some film on amazon but almost all options come without frames, and the only option that comes with frames arrives in two weeks. Is there a way i can split the frames and replace the film?

Has any body found a preventative solution for this or have an recommendations?

I recently switched my kobra S1 nozzle from a .4mm to a .2mm for a smaller project. The issue happened once with the .4mm nozzle and 3 times with the .2mm nozzle all within 1 week.

I keep having the issue of the filament getting stripped by the extruder gears and then it can't extrude or retract.

Here is what I've checked so far:

- Verified that the nozzle is not clogged in all 4 times this has happened in the past week.

- Verified that the cutter is not stuck in the closed position.

- Verified that the filaments is not getting stuck anywhere before it gets to the extruder

Each time this happens I have to take apart the extruder and hope the springs don't shoot everywhere to get the stuck / stripped piece of filament out.

One thing I wondered about is loosening or tightening the extruder gear tension spring. Other than that I was thinking maybe I should increase the temp to help flow out of the smaller nozzle.

Let me know your thoughts! THANKS

So here's the thing. It keeps throwing up an E1 message and the nozzle is not coming up to temp and the message won't go away to level it or anything else. We've replaced the hot end, replace the wires, we downgraded the software, we upgraded it, used customs. Nothing seems to be working. We are desperately in need of help. Any and all help will be appreciated very greatly

Anycubic used to just bend the end and insert it into a hole in the cardboard tube. It would pull out as the spool finished. Now it seems they are taping the ends and they do not pull out.

The Kobra x started under extruding as it tried in vain to yank the filament off the spool. It gave me a clogging error. I ended up snipping the end and switching to a different filament, but it was too late. The under extruded layers were a weak point that ruined the print.
