@stephen6309 I've just discovered the problem.
In Simplify 3D I have in Gcode z offset in -1, so the Web panel starts in 0 but for gcode is really in -1, so first layer was 105% layer height of 0.6mm, thats 0,63mm, and second layer 0,6 more, thats 1,23mm, minus 1 because of the negative offset is the 0,23 that webpanel was showing me...
@dc42 the problem is solved... the issue was that my friend didn't put the wires in the right position after some changes and that was making all the malfunctions, sorry for all the mess created about that 
. Now they're working fine finally. Thanks for the help.
Hello!
Last part was printed ok, so I put another one this morning and hope nothing fails again...
It's very strange because I really don't know what is or was the real problem...
Because of the updates I notice that the Tool 0 is not activated on power up and I have to press the "toolzero" in browser...
My last config.g is on my previous post... the line to activate the T0 is
M568 P0 R0 S0 ; set initial tool #0 active and standby temperatures to 0C
I also tried with the old line on my previous config.g
G10 P0 R0 S0 ; set initial tool #0 active and standby temperatures to 0C
But problem is the same... any ideas?
@droftarts Hello!
My paneldue was in 3.4.0, just updated to latest firmware.
I updated also Orca Slicer and I'm doing again the gcode files.
Also I recheck all wires and try to avoid any interferences between data and power...
So let's try again.
Thank you!
Hello,
I still have the problem, after update, change SD... no idea what's the problem... still going to the right and extruder moving so fast while it goes and return to print...
@dc42 thank you, I located my mistake... the speed in M558 was T100 by default and I didn't change it... I put 10000 and now it's doing the mesh leveling.
After that I will try to print again my old files and see if the problem I was creating this thread about it's still existing or not.
Thank you!
Hello again,
I updated to 3.5.4, it seems to be all working but I'm trying to make the mesh for the bed with the tool and when I hit the option to start the mesh with G29 
The printer moves really slow... like 0,5mm/sec, and I can't find where is the problem, because normal moves are ok, homing is ok and when I use G30 is also ok...

@Phaedrux Tottaly right, thank you! I think I my partner did that for the heatbed mesh calibration and didn't told me.
Hello,
this is my config and M122 results.
Anyway, I'm going to update now and test

Sorry for the missing information.
I haven't change anything, even slicer software is the same and old files are working wrong also.
Firmware version is 3.4.0. in a Duet 3 Mainboard 6HC with Toolboard 1LC with the hotend, extruder and 3D-Touch probe connected.
It's a cartesian printer.
Tomorrow I'll go to the place I have the printer and will upload config.cfg and M122 report.
The strange thing for me is that I was printing a lot of huge parts for a couple weeks... I change filament and put an old file again to print and starts failing suddenly.
I think tomorrow I will update firmware, what do you recommend? go for latest stable 3.5.4 or the last 3.6 RC3?
Hello again,
I have a Duet 3 6HC first version and I'm using all steppers drivers included on it... 4 for the Z axis (I have 4 steppers) and the other 2 for X and Y.
When Z is homming the temperature of hotend and heatbed starts going low until it stops... I alredy put a new power supply with a lot of more amperes but problem persists... so I really don't know if it's something that board can't manage or other thing.
Thank you for your help
Hello!
I was working good but suddenly my printer starts doing strange things... I have a Duet 3 Mainboard 6HC with a Toolboard and usually (the printer is big, 1x1x1 meters) I'm not in front of it and don't have a camera recording, only one to see if something goes wrong...
I've been having problems last week and today, I saw that while it was printing the X axis goes suddenly to the top right while extruder is doing a lot of noise like retracting fully... then it goes back to where it was printing and continue... but this is repetidly doing sometimes until the hotend is blocked because of it....
I cleaned all the board, I put a new SD card..., but problem persists... I really don't know what is the problem... it was printing really good and with no changes it's doing it now...
Any help?
Thank you
