Belt tuning
Hello,
I noticed some waviness on my prints recently, and belt status showed 280 for each belt, so I proceeded to tighten them.
Now, my belts seem a lot tighter, but the X belt makes some noises while the extruder is moving on it (See video: )
1) How do I get an updated belt status reading from the printer? I recalibrated XYZ, but the belt status in the support menu still shows the old values)
2) Are these belts too tight? The prints it makes now seem good, but I do hear the noise from the linked video while it's printing.
Thanks for the help as always!
Re: Belt tuning
I'm still building my MK3 so I haven't seen this yet, where does the belt tightening value show up and how can it tell?
Re: Belt tuning
From the support menu, there's a "Belt Status" option. Wouldn't be useful until you've fully assembled it.
Re: Belt tuning
i think you need to do a full intial setup calibration for those values to update.
My belts both read 276, which is within what the manual says is acceptable, but I am tempted to tighten mine too.
Re: Belt tuning
Ah, perhaps so. Will check, thanks! Does anyone have any advice on the noise from the belt in the video? Is the x belt too tight?
Re: Belt tuning
I think a self-test is sufficient to reset the belt status.. Your belts do look a little too tight (much tighter than I set mine). It also looks like you have the "R1" version of the x-axis parts. This version has alignment problems with the x-axis belt. I'd suggest you print the "R2" parts and upgrade since the new pulley is arrangement is much better.
Re: Belt tuning
I had perfect 250 250 belt tension, then had a crash, and now self-test reports x-190 belt status even when one has loosened off the tensioning screw completely on the x-axis. What is the process for further loosening? Is it to demount the print head and adjust the belt length? Why would a crash cause belt tensioning anyway? Could belt tension be a red-herring?
Re: Belt tuning
I believe the "belt status" is an aggregate load measured on the stepper motors during the self test. A failed bearing, or something else restricting the motor could lead to a low numeric reading.
Re: Belt tuning
In regards to the video in the first post, have you confirmed that your x idler bearing is still moving freely? If it is not a toothed idler that sound might be the belt slipping on a jammed bearing.
Re: Belt tuning
I have two MK3's.
I have to MK3s
Printer 1 X=276 Y=292
Printer 2 X=247 Y=275
Do i need to tighten any of these?

The recommended setting is between 200 and 280, so I would tighten the Y-belt of printer 1. (Maybe X1 and Y2 too)
