As the title says, when printing My P1P makes a weird noise when it’s retracing maybe? (I don’t know as that was where the sound gets the loudest). I tried contacting support but they said it sounds normal when printing. The printer is only 3 weeks old (I figure it happens outside my return window) and I’m getting frustrated. I’ve checked for clogs and I don’t want to take apart the hotend as I don’t want to mess anything else up or make the problem )if there is any) worse.
I don’t think I would be worried. I can’t hear any unusual noises. It sounds to me just like the extruder stepper doing a lot of retractions while it’s printing the hex section of your model.
Do you hear it while it is printing full top or bottom layers (with no retractions)?
I haven’t had a chance to sit down and swap the assembly, but if you still have the clicking noise I’m worried that this may be on a bigger scale for Bambu. Ill try to do one this weekend.
It sounds like the noise mine makes when I load in TPU and the extruder gears slip initially before I change my settings to TPU as it’s trying to feed to fast, it’s the only time I get this noise.
How tight is your tensioner screw on the extruder gear? It may not be tight enough causing the gear to slip a step. From Bambu new mine was in as tight as it could go, it was a bugger to undo but I did put it back like this when I upgraded to all metal gears.
It may stop by tightening the tension screw on the extruder if it is the extruder feed slipping is causing the noise. If you are unsure the tensioner screw is the one with the spring that pushes the small roller with the grey arm into the roller with the yellow gear,
P1S which I just took out of box about 5 days ago.
I filed a ticket with Bambu Lab last night for a “Toolhead front cover has fallen off”, which it has not. I used Clanking sound on ticket. I was initially able to print a few small items but now I get that sound when it does its initial print start routine so printer is dead in the water. They are sending me a new:
I do have a short video (13 seconds) where you can hear the clanking sound. Visually it looks like the toolhead does a very brief purge and wipe sequence, moves to the back left corner (X, Y both back left corner), the Y-Axis makes a short but abrupt move forward, the abruptly returns to corner I get clank and Toolhead has fallen fault. I took some tape temporarily between front cover and toolhead body on both sides thinking maybe the front cover was getting jarred down in the millisecond timespan and then reseating but it did not resolve. So I’ll wait on the parts I guess.
I’ve been around machinery my whole adult life (45 yrs) and clanking noises are generally not good. I would think they would do some sort of deceleration over what seems to be a stop by hitting a physical limit as that Y-Axis elapsed time can’t be more than about 1 second for the full forward and reverse cycle fault.
Yeah, it does sound almost normal but I do hear unusual “sudden hit” gear teeth nashing “click” at each end of the retract/un-retract movement that isn’t quite right. I suspect there is a defect with one of the gear pinions or the like. Whatever it is, it does sound like am unfortunate mechanical issue.
The haste with which tech support responded to my problem makes me wonder if there is more to this issue than just MY Bambu P1S.
I sent my help ticket to support about midnight US Eastern Daylight Time Tuesday and when I checked my email at noon on Wednesday there was already a response from Bambu Lab asking me for a QR code off machine but in that same message they said they were sending the hardware to hopefully repair it.
That is good. I’m certainly not complaining. I wish all my electronics/computer tech support responses were like Bambu’s support.
I hope they send a packet of extra screws because those are some tiny screws inside that toolhead assembly.
