Hello, new here so bear with me.
Ive had my P1S for about a year with no issues. Two days ago i started getting bed leevling errors, which ive experienced before because of the build plate but after checking that and the few things i knew I was still getting failures to auto level. I thought it might be time for a firmware update so I updated that and studio as well. Leveling issue persisted. So i followed the wiki and checked the bearings, heatbed connection, theres nothing obstructing the z axis. I checked the rear bearings and rail as well. While I had it off the desk to do all this I figured i would send a print from my phone just for convenience and it printed. Took the printer back to the office and the next day tried to start my print with the same general errors.
Im able to print from my phone, and manually level the bed from the screen. Ive rebooted, rolled back firmware, and its still the same… my phone will print, studio won’t across multiple models.
I get a different error message every single time I try, which is part of what’s got me lost. None of these errors occur when printing from bambu handy, I havent tried the SD card yet. Even when the print plate error is the only code i get and i remove the print plate the next time itll throw a force sensor. After the print fails i can go back and rehome the z axis manually without any errors, with and without the print plate
The errors im getting:
External disturbance on force sensor 1/2/3
Force sensor 1/2/3 too sensitive
Print plate not properly placed
Try to Fully uninstall Bambu Studio (delete config/cache folders too).
Reinstall the latest version from the official site. You also could try to send it via g-code on a sd card if this works it might mean packets are getting lost communication between your printer and your pc meaning it’s a networking error. Im not familiar with this problem so if this does not work you could make a ticket with bambulabs support @Coreyjenkins24
I attempted this, and trammed the bed, also loosened/retightened the screws on the bed and still the same behavior. Itll print from sd card and app, no studio
After your suggestion i trammed the bed, i wouldnt say elevated heat level, its the first time ive tried to print with petg but i get the same behavior with pla
I tried to make it clear I wasn’t suggesting to tram it but I guess I should have been more explicit.
But the loosening the bed leveling screws was definitely what I was going to suggest next if you had trammed it and you were operating at an elevated bed temperature. So that is a good datapoint.
At the point I’m wondering if you are having the problem where the z-axis movement jiggles the sensor connector on the main board. I don’t have the link handy, but it’s a known fault and an easy fix, you just dress that cable so it doesn’t wiggle.
That interesting i would suggest making a ticket with bambu labs support
Just to warn you i would watch out on unscrewing some of the screw on the bed i could mess up your printer but it is ok to screw and unscrew the levelling screws underneath the bed that have nubs on them
Ah, I read that correctly now. It needed it honestly, they were pretty far off from where they shouldve been. I will say tramming and loosening/tightening got rid of the force sensor codes, but im still getting print plate not properly placed even without a print plate in the damn thing. I havent found anything about the z axis wiggle and cable but i will say ive moved the cable around and connectors, thinking something may have had bad contact
Yeah ive got a ticket open but its not going so swimmingly. Im like ive done x and y and theyre like well did you do y? Like uh yeah I said that already
Have you changed anything on where your printer is located? I had the same issue the first day I received my P1S, I made my first calibration on a less than robust desk and it failed. I then moved the printer to its final location, a sturdier desk and everything has been fine since.
Nah, its been in the same place since i bought it. It sits on a ridiculously heavy MDF bar height table. Its sturdy enough I can solder while it prints. The only thing thats changed is ive bought an AMS in the last month but ive printed a lot since then
OK. The wiki advises to check the buffers screws to make sure they’re not overtigthened. The way I understand the wiki is that they may protube and hit the bed. I don’t know how this could be possible but worth checking as you installed it recently.
Step 7: Check AMS hub/ Filament buffer’s screws
If you have installed the AMS-HUB or AMS-BUFFER, if the screw is over tightened, that may also stick the z-axis when the bed is near the nozzle, so try loose these two screws for 1~2 rounds :
