@JoergS5 you are right with the U-Axis, because this was the main firmware of my idex machine... but I think this would not cause an layershift at X, or?

@Veti

Yes you are right, for the Y-Axis with the NEMA 23 I had no problems at the moment...but I can also change this...

I attached the datasheet of the NanoTec Motor here:

NanoTec_NEMA17_SCA5618X2804-A.pdf

I changed the motor current a few times... now it is a little bit higher...

I am not sure, if you have tool changes somewhere and U is undefined. I just want to exclude possible reasons.

@CR3D said in Layer Shifts with Duet3:

Board EXP3HC firmware 3.2beta (2020-09-14b1)

can you update to the latest beta? just to rule out a problem with the beta firmware.

CR3D

Now I updatet the firmware of the main and expansion board to 3.2 beta 3.2

And get this error message:

Board 1 does not have input handle 1100

@dc42 do you know this issue?

dc42

@CR3D said in Layer Shifts with Duet3:

Board 1 does not have input handle 1100

@dc42 do you know this issue?

That can happen after you update tool or expansion board firmware if you do not reset the main board afterwards, so that config.g is run and sets up whatever heaters etc. you have configured on the expansion boards.

I've just released firmware 3.2beta4 at https://github.com/Duet3D/RepRapFirmware/releases/tag/3.2beta4 so please use that instead of 3.2beta3.2.

CR3D

@dc42

Ok you are right! Thank you!

Now I installed 3.2 beta 4 ...

Do you have any ideas about the layer shifts?

dc42

Do you still get the layer shifts with 3.2beta4?

Is the axis showing the layer shift controlled by a motor attached to the main board, or to the expansion board?

CR3D

The testprint with FW 3.2 Beta 4 is running now...till now it looks good...

But did you changes in this way?

The axis with problems was connected to the expansion board...

CR3D

So the test print runs without problems!

@dc42 did you made any changes in this direction?
I did not read something about a topic like this in the changelog...
Please let me know, because there are machines outside from us with the old firmware...
