Constant X and Y resonance frequency errors

Bambu Lab X Series Troubleshooting
1

Since unboxing I’ve been unable to get rid of constant errors regarding the x and y resonance frequencies being too low. The errors suggest tensioning the belts through the automatic tensioners by loosening then tightening the screws on the back. I’ve done this multiple times with no signs of improvement. I’ve also followed the guide that asks to loosen the screws, move the toolhead around then all the way to the back, then tighten the screws again. This didn’t help either.

Every print, I get errors saying that the resonance frequencies are too far from the last calibration and that I need to clean the rods. I’ve done this multiple times with IPA as well. I’ve submitted a ticket to support in the app and have only received a message saying they’d “review the log” and haven’t replied back since that message 2 days ago.

What more can be done to try to remedy this outside of just waiting an indefinite amount of time for support to reply? I’m getting extreme ringing on my prints and poor quality.

Update: support reached out and said that there’s signal lag on the toolhead PCB so they’ll be sending a replacement TH board. I’ll have to update again once that arrives and I get it installed.

There are a lot of problems , most of the time something is too loose in the system . Maybe at the ToolHead or at the X/Y Joints , a screw or something else .
The other problem is a problem with the sensor . It is possible that the adxl sensor Ist broken or not ok .
You have a feeling for the belt tension ? If you had a feeling you can check it . It is needs to sounds like a deep guitar side on a way of 150 mm . Rough Orientation .

Otherwise is that ok , check the screws or feel if maybe something loose .

I think Bambu had a lot of work this time . That is normal with a new printer . Give them some time , they will answer :wink:

The belts are tight.

I similarly think it may be due to the sensor itself. I’ve popped off the toolhead cover and checked for loose wiring and haven’t found anything of note.

Hopefully they get back to me soon as I’d like to get this figured out before the return period otherwise this printer might have to go back.

I will cross my fingers . I have no more ideas in this case .
Hopefully it will go fast for you :wink:
