I think I read somewhere that I should use relative extrusion. is it right? Then I should include in the start g-code

RE: Z offset resets on every print or Homing and start gcode askingposted in Duet Hardware and wiring
Now I set my Z Trigger height in G31 according to this:
https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_heightAfter that my print start has began on the right Z height.. Thanks for the advices. As I see now, that was my problem..
My other question is, what do you think, what should I include in my start or maybe end g-code on an idex.
Is there something special for RRF that I should include in these?

This is very convenient, thank you for the tip.
I had a few succesful print since I made the Z-offset correctly.

About 3mm Between the tip of the nozzle and the tip of the BLtouch. Thats what you define in G31, isn't it? Thats why it is off with X-29.75 and Y-14.5. Z-probe position from the nozzle's point of view. -

The Z offset between the nozzle and BLTouch is at about 3mmI don't know if it means this, but it is not near to hit the bed when it retracts

I have tried so many ways now. In the beginning it was Z0.0 in G31.
I have to babystep down, usually it grips in -2.1.
But I will have a try again.. -

It doesn't show value but I guess if after a G30 probing it stays well above the bed then the Z0 has changed.
That's what I am doing in the Z-Offset macro yes. Babystepping down. Then it saves the Z0 until re-home or print start.

The Z-Offset between the nozzle and the bed which I would like to set with a BLtouch@peter247
Sorry for the misunderstanding.
Yes I have, and I can set it. Then I re-home, or start a print and the Z-offset changes back to some other value. Like it got a new Z0, thats why I cant babystep down more I think. So when I start a new print it only prints in the air well above the bed and in DWC it says its on Z0.3 on first layer. -
Z offset resets on every print or Homing and start gcode askingposted in Duet Hardware and wiring
Hello all,
I am familiar with marlin but I chose DUET and RRF for my newly built IDEX.
I have a strange problem where I use a macro to set the Z offset. I set it easily and then the Z0 position is fine until I start a print or home my axes. No matter what it changes back to old Z0 and can't even babystep down to the proper position.; General preferences G90 ; send absolute coordinates...

I also would like to ask for some specific things that what should I include in my starting G-code? Now its only consist of homing and some small movements, nothing special.
Could someone help a newbie there?
Thanks in advance.
