Thank you all for your quick and efficient help.
I found the error, it was here:
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
It was Z0.6, after an earlier setup and I skipped over it several times. In my case, zero is a good solution.

Hi,

@deckingman It is possible to print out the G code while printing like on CNC?
@deckingman Thanks, I'll try and give feedback.
@rjenkinsgb Yes, but you can find here again:
@rjenkinsgb When I built it, I measured the backlash using the method you wrote. I have measured it several times since then and get the same value. This is unlikely to be where the problem comes from. Mainly because the bed goes higher (endstop) to the first layer and then comes lower, 0.2mm.
@rjenkinsgb Sure, I don't take personal
If there was a backlash, the motor shaft would move, but the bed would not. However, the motor shaft does not move at the second layer.
I measured the backlash and about 0.01mm (the bed moves on a ball screw)
@eduard
This is what the table leveling process I follow looks like:
The duet is set above 3 points on the bed:
M558 P0; No Z probe
G30 P0 X90 Y0 Z-99999; probe near an adjusting screw
G30 P1 X150 Y185 Z-99999; probe near an adjusting screw
G30 P2 X30 Y185 Z-99999; probe near an adjusting screw and report adjustments needed
At each point, I adjust the duet to Z0 and adjust the head bed distance to 0.2mm with the bed adjustment screw. Then OK and restart the process to check back.
The thickness of the first layer in the slider is set to 0.25mm.
@rjenkinsgb Thank you for your reply.
The nozzle distance from bed was set with a precision 0.2mm metal gauge. The movement of the bed was calibrated with a 0,001mm precison indicator (+-0.015mm)
Mechanical failure is completely ruled out.
All already layers except the second are executed and perfect. When I use raft, the print is perfect and in all directions.
@phaedrux Unfortunately, I no longer remember exactly what was and what wasn’t, but now I’m sending a new one that doesn’t have raft. During yesterday's test, I printed this and the second layer went to the first one here, too, without raft.
@eduard unfortunately this was not the problem. At the second layer, the bed still does not move. The third is fine and so on.
@phaedrux OK, I set it now to Z0.2 and I give it a try.
@eduard I have to set G92 Z0.2 ?
@phaedrux The Z is set to 0.2mm from bed.
@phaedrux Thanks for your reply.
The printer works good except this weird second layer problem. To avoid this problem I using raft. At printing the raft two layers print on each other without moving the Z axis, but the third and beyond is good.
I can move the Z axis by command, or by baby steps and it is very accurate. While I print with raft, the calibartion cube in Z axis is under +-0.03mm deviation.
I checked everything what I can imagine. I do not have a Z probe, leveling manually.
Here is the config file:config.g
Bests,

Hello Folks,
I have configured a fully working duet3 and testing the printer. I solved evrything but can not find the problem on second layer over extrusion. The printer prints perfetly the first layer, but on the second the bed does not descend (0.25mm is the layer height) On the third and everything after that it does.
Where can I search after the problem?
I do not have automated bed leveling.
@Phaedrux Firt of all, thanks for the help!
I did not want to try instable version, just under the beta was not indicated it is an instable version. In most cases, the beta is just a fixed version.
After I realized, there is a stable release, I stick to that.
The documentation is very fragmented, and unprioritized. In point of setup unnecessary things come first, and important one are follows. A guideline is missing, even if I made the setup several times, after a year or so, is hard to to pick up the thread. Duet can act like an idustrial equipment setup guide to prioritising the setup process with one entry point.
The drawings has to be on one place for all the boards: schematics, connection diagrams, topology, and firmwares. The fw files has to have the version numbers in their names!
Just check the macros, they are very important and are hidden somewhere in the tree. And they are also not settled.
these are just thoughts...
Anyway, thanks for the hard work, it is a good hw sw.
Thanks for the help, it is working now.
@jay_s_uk Tested with M122, gives a bunch of errors. I'll check with 3.1 DWC.
@jay_s_uk Thanks for the fast reply. Then I stick to 3.1.1.
The RepRap Config not created valid config file, and all the tools, motor and setup are gone. Some advice, how to re-create the config?
