I already did it, many times, it doesn't help.

Extruder and bed temperature is very unstable. Even if extruder and bed are cold the temperature is changing +-2.5 degree. It is not normal.

I use PTEG and did a lot of calibrations but still have oozing. Did removing little disks from the hotend will solve that problem?

I think #define DEFAULT_AXIS_STEPS_PER_UNIT need to be hardcoded, one can put additional E1 steps per unit after coma.

Don't want to start a separate topic because it is the same problem.
There is no separate Esteps/mm for left and right motor. If i move extruder 300mm, i 've got 297mm on the left and 300mm on the right side. How to solve this problem?

I found the issue. It is this part, and it is bent where the bolt of the bottom roller goes through.

I did some research and I think that the rollers are not set correctly, they need to be adjusted. But I don't know how? If i rotate an bold on the bottom roller nothing happens.

If i move the extruder up by hand, it moves a little bit. It's not really tight on the rail. Is it correct so? Or the rollers can be adjusted that the extruder is not moving up and down?
Please have a look, this is the video how extruder is wiggling

And how it moves on ...

Hello All,
I’ve got a new A10M yesterday per Post, and assemble everything today. I’ve notice that the movement along X causes the different distance from the nozzle to the bed in the middle and on the left and the right side. The problem is the Belt, that probably supposed to be inside the metal ...
