Anyone elses toolhead slamming against front left wall after print?

Ever since the firmware update and software update, I’ve not had 2 prints where the toolhead slams against the front left after printing. I’ve maybe printed 5 things. Seems like larger things doing it.

The print is at 99%, toolhead comes to front, slams against left side, slams against left side again, front cover falls off, it goes to purge area with error.

I dont have your problem but usually i do a full calibration after a firmware update.

I guess I did just update today, I’ll try that, tyvm!

Are you printing with AMS?

Slamming against the front left of the printer is how it cuts off filament before retracting it. You see it all the time when unloading filament as well.

Sorry but this action is not normal.
Unless he has lost some magnets on the front cover of the Hotend/Extruder.

Right, no magnets have moved. Checked that right away. I think a calibration has fixed it.

Spoke too soon, just got done with another higher Z print, got the error about the front falling off lol…
This time it just banged enough to trigger the sensor but the front cover didn’t actually fall off.

Happened again a little bit ago. Perhaps it’s not knocking it off every time and triggering the sensor. I’ve had it not fall off though AND trigger the sensor.
Already done one calibration so unless it’s losing XYZ coords between power off and power on? Is there a way to check the allowed XY on it? or Force of movement for the filament cut? I think that’s what it is doing…
Maybe it’s a worn cutter…

I’m suddenly having this same issue. I heard it from one room away. Knocked the cover off. Maybe the honeymoon is over lol. The only thing I’ve done differently is that I turned it off for a couple days waiting for filament to come in. Did it forget its homing? I ran a self test twice. One it failed and second attempt passed so I re started the print only to have it smash into left front wall again aaarrgg!

I had something similar happen today. Haven’t used the printer in a few months - upgraded from 1.0.5 to latest, and now a print that I’ve printed dozens of times before makes these screech noise for a moment (happens around the front right corner) about 5% in, which causes it to loose its position, causing it to slam into the right wall.

I uninstalled and reinstalled Bambu software and also did a factory reset on the machine…so far so good.

Saw an update to this, didn’t happen again after I upgraded firmware and reran calibration, so perhaps it was a user error in that I forgot to calibrate or such unless it really was the firmware but I kinda doubt it since it wasn’t every print.

Don’t know if this helps but I had this issue with my p1p after a software update and accidently found a solution when using the wrong slicing software and noticed that using the p1s slicer on the p1p printer solves the issue and still prints perfectly.
