ich hatte neuliche einen etwas “größeren” Druck als üblich abgeschlossen.
Das Druckbett ist im Anschluss fast ganz nach unten gefahren, zwischen Druckbett und Boden des Drucker waren vlt. noch ca. 1cm Platz.
Als ich den Drucker dann wenige Stunden später erneut in Betrieb genommen hatte, hat er bei seinem üblichen Selbsttest vor dem drucken das Druckbett gegen den Boden gefahren, das Ganze hat sich sehr ungesund angehört, zumindest für den Drucker.
Ist euch schon mal ähnliches passiert?
Ich bin eigentlich der Meinung, dass sowas unter keinen umständen passieren sollte.
English version:
Hello all,
I recently completed a somewhat “larger” print than usual.
The print bed moved almost all the way down, there was about 1cm of space between the print bed and the bottom of the printer.
When I started the printer again a few hours later, it drove the print bed against the floor during its usual self-test before printing, the whole thing sounded very unhealthy, at least for the printer.
Has anything similar ever happened to you guys?
I am actually of the opinion that something like this should not happen under any circumstances.
Mine does this also. I don’t believe there is an encoder on any axis so it can lose it’s position if the power is cycled and the bed seems to lose it’s position at the drop of a hat if it’s near either extreme. I don’t think it’s doing damage, although I’m not sure if the noise is the belt skipping or the motor missing steps. I do wish it didn’t do it.
Yup, mine does that too … first time I ran over thinking it was going to explode or something… Very Loud, I am surprised it works that way. Bambu Labs must be aware that it’s happening.
Side note, my prusa Mk3s slams in to the side and back during homing making several hard clunks, I think its the same thing with the P1P using the current peaks to distinguish end stops.
I have the same issue, printing many large items and it sounds terrible and I think it is not healthy for the belt or motor on the long term. It even happens if i start a new print directly after the last one and I am wondering why this intelligent machine can’t remember its last position after printing. Should be easy to fix that in the firmware…
