@mario Dear my friend,

I got the new board then I realized that the TC2209 board had malfunction as well so I changed it as well.

Now everything is much better.

I set the 3200 as well so now it is pretty good but still I have problem with my scan.

520

This is the object I try to scan

521

This is the scanned one...

Why is it like this with hollow and much empty spaces?

How can I solve it?

Thank you a lot

If you purchased your HAT at Watterott electronics, then just contact them via E-Mail. And tell them that you already have purchased a couple of HATs before. I just called them and they will pre-solder and check the HAT for you before shipping.

@mario I tried to solder the jumpers on HAT but unfortunately the C3 got fucked up. As I press turning table in UI it just jams. I ordered another HAT (The 3rd one...)

I will keep you updated...

Thanks a lot man

Your video shows the behaviour. The scan is doubled. That means that one scan process turns the table two times. Check the motor you are using. Find out if it is a 200 or 400 step motor. If it is a 400 step motor set steps in the config to 3600. If you are using a 200 step motor, set the steps to 3200.

Also check the motor driver you are using. If you are using a TMC2208 or TMC2209 you should solder some bridges to the HAT (depending on the used driver). Have a look to this post:

Hi friends,

I calibrated well, everything is working fine. As suggested by documentation the Motor value changed to 3200 but this is the scan of a simple USB charger of samsung mobile (available around and everyone knows hoe does it look like).

All the helps, suggestions and advices are very appreciated.
