Its all good, I'll run it in the printer and have a printer-watch party 😂 I printed another model by the way, the owl calibration model. It failed in the same way (print head goes nuts). So definitely a printer problem, not a gcode/slicing issue Also I opened up the X stepper motor. This fell out. Not sure what it is (a washer?)but whatever it is, it looks bent which im guessing isnt good.

There arent fans in the mainboard compartment, but there are two in the print head. Sorry if this is a dumb question, but what is the purpose of the gcode that you sent? If you cant see any filament being extruded how will you know if the print fails?

Thanks for that thoughtful response! Anycubic sent me updated firmware so i'll try that first and if the problem persists i'll figure out out to swap the stepper motors. Thanks Greg and yes please keep me posted on that print 🙂

Sounds pretty similar to my situation🙂 but in yours the prints starting failing when you replaced the mainboard, so you knew pretty much what part was causing the issue. It could literally be anything on my printer that's causing these prints to fail. Are you suggesting that I replace the mainboard?

Hello, @GregValiant! Quick update: The print failed 10 hours in, even with the new SD card. It failed for the same reason: It starts printing the model at a much larger scale. The only thing left that I can think of that is wrong is what you said: Something is wrong with the printer. My printer (Anycubic Kobra Max) is still under its 30 day return so I figure I'll just return it and get a new one and save myself time trying to diagnose whats wrong with the printer. I'll exchange it for a new Kobra Max and hopefully that one will print just fine. If it doesn't, then... yikes. Anyways, I'll keep this thread and you updated, thank you for your continued support!

Literally as I read your message I was pulling my hair out because I got a 64 gb card and the printer wasnt reading it. Once again I appreciate your reponse and help so much. I'll go to Walmart real quick and get a one with a smaller size now Update: Got a new SD card. The smallest size they had was 32gb so I went with that. The printer read it successfully and now its printing. More updates to come, fingers crossed.

@GregValiant Thanks so much again for that incredible response. Its good to know that everything is good in the Gcode. Its just so strange because everything else prints really nicely on this printer, its only this model. I'll look into how to troubleshoot the stepper driver/motor, I dont even know where to begin on that. I'll also try a new SD card. I'll keep you posted, can't thank you enough for your help 🙂

@GregValiant is this supposed to happen? The model size in Cura is: x:179 mm y:229 mm Z:154 mm Within the gcode, the model size is: X:198.04mm Y:248.41mm Z:154.95mm This makes sense, since the raft adhesion plate adds some size . What doesn't make sense is why the Max numbers are so big (circled in red on the right). Shouldn't the max numbers be around the same as the model size? Is this whats causing the printer to all of a sudden print the helmet at a really big scale? I've looked through the gcode of some of my previous prints and those max numbers are around the same as the model size. I've attached an updated gcode file if you'd like to take a look. Any help would be greatly appreciated, thanks in advance 🙂 1052065580_DareDevilHelmet_HorizontalOrientation.gcode

Wow, thanks so much for that explanation and the time you spent looking into this, I am really grateful. I'll try reformatting the card or just using a different one, thank you 🙂 If this doesnt work, do you what parts on the printer could be the culprit?

Hello! I’ve been having trouble with my 3d printer (Anycubic Kobra Max) and I’m at a loss for what the problem is. I’m trying to print a daredevil mask and whenever I try to print, one of two things happen: 1. The print head strays away from the print area as seen in the video for whatever reason. 2. The print makes some progress and then starts printing the helmet at an extremely wide scale, as shown in the attached image. I thought this was just a major case of layer shifting or something but I’m not so sure anymore. None of the belts are too loose or too tight, the printing speed isn’t too high and the nozzle or print head isn’t colliding with any of parts. Everything looks good in the slicer (Cura). Maybe the gcode is faulty? Any help or suggestions would be immensely appreciated. If you’d like me to send any files or anything please let me know and I’ll send them. The gcode is attached too idk if that helps or not. Thanks in advance! 1793070283_DareDevilHelmet_HorizontalOrientation.gcode
