The circle is not standard
V-core3.1After the assembly is completed, the round hole printed after the belt calibration is non-standard and a bit elliptical. I need help,

Check if belt tension is equal, not too low, and that the pulleys are not slipping on the motor shafts.. that's the usual causes for non-round circles

Is there any standard for belt tightness, such as how much hz is the best for testing
other-emerald•3y ago
No, we usually hook an accelerometer to it and run the belt tightness macro. You can then get the files off your machine and test. You're looking for about matching peak height no matter what their actual height is, and more or less in the same area. Err on the side of too loose because too tight will 100% make your motors stall.
If that doesnt work, you'll need to re square your machine which is a whole deal.
Failing all that there is an out of square calibration procedure you can use but you should try exhausting hardware fixes first.

belt tightbedd maxro,Where can I find it,Have you used the tutorial
other-emerald•3y ago
If you dont see the belt tightness macro you need to enable it in settings. And I don't know any tutorial for it unfortunately

Ok
Solved the problem. The reason is that the x belt pulley is installed reversely
Thank you

It's a little better than before, but it hasn't been completely solved

What does your tightness graph look like?

I have not installed adxl345, not ratos I can also measure using klipper?
Here comes the adxl345 I bought. After setting the resonance value
other-emerald•3y ago
You can measure with klipper but I'm not sure the procedure. Please do that and post the belt tightness graphs. It's more of an art than a science so we'll try to work on it together.

The belt calibration method recommended by another brother has been completely solved. Thank you very much https://www.printables.com/model/151815-belt-tensioner-meter-9-mm-petg-prusament

How does it works?

Similar to this, adjust the two belts to the same position in the section
united-yellow•3y ago
Do have I to adjusts the belt positioning them in the middle between min and max?

Among the suggestions, the worst is not very good
Try the effect first. I hope it can help you
