Hello, I need your help before I throw my x1c out the window. My problem is that my bambu is constantly scratching over the object. When I got the printer everything was fine.
The following things I have tried so far( must have been more^^):
Bed manually re-leveled (several times)
Belt tension adjusted (several times)
X/Y Rods cleaned (several times)
Flow properly calibrated
Speed down to 50mm/s
Tested different plates (PEI/Engeneer/Cold/G10). Run the calibration each time
Back to the last and penultimate update. Of course the following always run through the calibration again.
Tried different filaments(PETG/ABS/Pla+)
Increased temperatures
Printed different models. And sliced with Orca and Bambu Studio.
Always used Gyroid as infill.
Currently I am quite perplexed. I somehow have the feeling that the zoffset just does not fit.
Can you elaborate on this? Is the nozzle hitting the print and losing steps which cause a layer shift? Is the nozzle just leaving marks on the top surface? Pictures/video really of the problem would also really help.
X1C is a good printer , it has it quirks as every other 3D printer
Not sure in your case if that would help, but try this. a lot of people complained with issues after the last firmware update , for me after each FW update some issues
Factory reset, machine calibration
If that does not help, probably worth opening support ticket. They are not too quick but they do respond and try to be helpful
You’re right about that. I’ll try to post a video today or tomorrow.
A layer shift is not visible. For example, when printing the Calibration Cube from Orca Slicer or Bambu Studio, the walls look pretty good. Also when measuring the cube the values are quite accurate (deviations of ±0.06 mm).
Thank you for answering.
now finally a video about it. The sound is a lot louder when you stand in front of it because the fans drown out a lot. I printed a 7x7 cm test piece with 15% gyroid infill. Strangely enough, I still had a layer shift (see photo). For example, if I This didn’t happen when I printed a test cube from the Orca Slicer or Bambu Slicer.
Small update.
I have now used Rectilinear as an infill. Because of the less movement, things went a lot better. I also didn’t have any layer shift in the print. The walls looked neat.
When I printed again the cube i took a close look at the printer when printing. I watched everything for a long time with a flashlight. I noticed that the noise also comes from the scratching at the connection point of the X-Axis Carbon Rods Assembly. The plate at the end of the X-Axis Carbon Rods Assembly scratches the right Panel and slightly scratches the left Panel when the printer prints infill. On the right side you can clearly see scratches on the right panel. There are also light scratches on the left panel. I therefore removed the right panel. There are no foreign bodies or anything like that between the panel and the plate of the X-Axis Carbon Rods Assembly. Therefore, this could cause vibration or movement that negatively affects the hotend. I also noticed that with the silver pulleys the belts run straight when moving forwards and backwards. Except for the silber pulley at the top left. There the belt strangely moves up and down as it moves forward and backwards. I have attached another picture. Because of the light it is not as visible as it is in reality. The question is whether the silber pulley has anything to do with it?!
Tomorrow i will run a Test without the right Panel.
I have a 1/4" of clearance from both outside panels to the x-axis carriage. The outer edge assembly is not even close to the outside panels. If we are talking about the same items. And i see no scratches on the panels.
i will check when i run my next print, but it seems to be similar to mine and normal for X1C
Prusa does not have such a sounds
EDIT:
Tried it can’t here difference with mine one
the rattling is the gyroid in infill really annoying and but i have 17KG stone base and now prepared 50KG stone where my two printers sit, as the gyroid affects a litlle the second printer when both working
It seems normal, i.e. similar to mine, but we can miss the issue because it is recorded.
In case the nozzle is scratching the print, there should be visible marks in the print.
If you comparing to another printer, and with some infill patter, you should also consider the printing acceleration and speed.
Hello small update.
I have now replaced the entire carbon X-axis at my own expense. The Bambu support always answers after a day, but the answer didn’t help me in any way. It’s a difference like night and day. Everyone who said it was as normal as it sounded to me…definitely not ;).
