I have reverted to version 1.9.0.70 of Bambu Studio from April 10, which is definitely the version I used for a period of time when I successfully printed with ABS. I uninstalled the previously installed software and also deleted all the cached data on the computer as suggested, but the print failed again.
Now my doubt remains about the firmware version, because it is true that I went back one version, but in reality, it is impossible for me to know which firmware version was installed when the printer was delivered to me.
Do we have any news from the ticket sent to support? This is becoming very annoying, I need to print in ABS for work purposes and I donāt want to disassemble the whole printer like I used to with the Creality printers. I chose this printer because it is presented as the best in terms of quality and maintenance.
There is no way to check the chamber temp from the app/studio manually for the p1s right? I know I can set fan speeds w conditions on the chamber temp on the slicer but I couldnāt find anywhere to monitor it. My handy app glitches sometimes and show my p1s as an x1 and I get flow calibration and chamber temp gauges on the app (both useless, just a glitch) momentarily but other than that, no luck. I have put a outdoor weather monitor unit inside mine to monitor the temps/humidity from outside
Are we hoping that is that the problem? I think we are far awayā¦ Iām pointing to fast smoothness travel, next test for me is to remove the belt and check how fluid all the movement are without involving belt and steppers.
That is correct, Iāve had the same glitch with spegetti detection on our P1Pās.
But as far as I know if you have the AUX fan and the chamber temp sensor within the enclosure, youād be able to do what I do as well.
Iāve also made it so no matter what every completed print will turn on Aux 100% then wait for bed temp to drop below 39c and then itāll notify that print is complete. Kinda weird though because it states a [soft alarm] āBed temp exceeds normal temperaturesā
Ive been desperate for a solution to a very similar problem. I cannot print any filament that requires an enclosed chamber without getting layer skips and eventual print failure after some horrible noises. The problem only happens if the door is closed and the chamber temperature exceeds 43c.
I strongly believe this problem is related to heat, despite the X1C supposedly being rated for 60c. However, changing the MC board fan to a larger one that directly cools the heatsink did not solve the issue either.
I measured my chamber temp manually my successful print, it was 57c in the top corner by the hinge and 37c by the bottom hinge. Think printer stated 48c
If you want to test one more print you could manually turn on the aux fan to a low setting to even out the temperature in the chamber, and specifically lower the temp by the steppers.
Thank you @JonRaymond. So the part fan is the one that cools down the extruded filament from the nozzle. I suppose then that the hot end fan is not adjustable because it must keep the passing filament cool.
Based on my years of printing experience (not with this printer, obviously), the chamber fan MUST always be active to expel exhausted air, and when printing ABS, for example, to filter out toxic exhalations.
The good point now is that the auxiliary fan is the one that should be used to control the chamber temperature, in my opinion.
The chamber fan vents through a carbon filter to atmosphere, running it will/can reduce chamber temp. The aux fan circulates the chamber air, and will only even out the temps, not reduce them- atleast the way I see it.
This is true butā¦ It depends from what temp you have in room where the printer is located, iām trying now a print with chamber fan at 60% speed, iām lucky because the printer is in a cool room, what happens if the printer is located in a room with 45Ā°? (most of the cities temp during summer).
BTW i think the best is that Bambulab solve and automatize settings, many people buy this printer because is acclaimed as āready to useā, if i must spend hours or use orca slicer tuning profiles, for sure i donāt need to buy this printer i guess.
UPDATE:
with Cham fan at 60% print fail again, after previous point but fail, the cham temp is 41Ā° i try now with aux fan at 70% like PLA profile, but here we are leading versus a ridiculous fix in my opinion.
Yes, certainly not a fix. Just to rule out temperature.
I completed another ABS print on mine with standard settings. BTW
Also got a reply on the ticket but 99% sure itās made by an AI only analysing the attached images not considering data log and videos of the failā¦ So standard suggestions like moisture and clogged nozzle
Itās not good to see this response. More than 50% of a productās value is related to the quality of customer support. I am sure that sooner or later we users will be able to solve the problem on our own, but I donāt know if it is fair to do so. As I have already said, I invested in this product because it was advertised as āready to useā; otherwise, I could have chosen another product that is equally fast but cheaper, like the FLSUN.
Another thing I am curious about is whether there are official technical support staff reading the threads on this forum, or if it is a platform created solely to provide a space for users.
Iām in contact with a support guy; however, he seems too stumped by this problem and is trying to throw standard solutions at me and is hoping one will stick.
(like did you check for clogged and or bent nozzle, is the extruder clean etc. etc)
Told him Iām using BL ABS, with standard settings, nothing special
