Hi, during my usual calibration routine i printed a califlower from vector3d and found that my printer prints very skewed. Usually i would add a skew correction to the printer.cfg, but as this is not intended (as the files are protected). What is the official way to deal with it? I already perform…

See Advanced Mode in the printer menu.

Also strange. I got zero degrees on my first crack at the Califlower while trying out ASA. [image] Experimenting with ASA material shrinkage on the U1 U1 Toolchanger The pre-production unit and all software used for this post was sent to me for (unpaid) pre-re…

Hi @Wombley I don’t want to activate this option because it could result in warranty limitations according to the dialog. It’s an out-of-the-box problem, so I expect an out-of-the-box solution.

It seems you know about inaccuracies and the possible causes of wrong scew correction settings. In this case I would simply use the advanced mode because the machine will not break because of this correction. Anyway, you could open a ticket and get sure it’s ok. https://snapmaker.formcrafts.com/…

OK, I’ll keep an eye on it—I’ll check on Monday.

Is there any information available on what the belt tension should be and how it can be checked? I don’t mean how it is adjusted, but how you can check whether it is actually correct.The wiki only mentioning it should be checked monthly but not how.

Great suggestion—I’ve already passed it on to the WIKI tech team. They’ll work on making the page description more detailed. I’ve double-checked with the tech team: belt adjustment boils down to these steps: Use a 2.0 hex key to loosen the two screws shown in the picture.（Do not unscrew the scre…

This Guide only shows how belt tension should be adjusted. But still the question is how to check if the belt tension is applied correctly. e.g. by moving the printhead to a certain position and strum the belts and compare a frequence in Hz like Prusa did it. For example i performed the belt tension…

If you want to test it yourself, you need tool： 1.Belt Tension Gauge（As shown in the image below） 2.A reference fixed position [image] —————————————————————————————— Here is a more detailed process from production for testing whether the belt tension is reasonable： Loosen screws No. 1 and 2…

If you’ve confirmed it’s not a belt issue, the tool-head coordinates may be inaccurate; try adjusting them by referring to this WIKI article. U1 How to adjust the pick & park coordinates | Snapmaker Wiki
