Hi, perfect you find the problem.
Your solution solves it.

Thank for your help !
Have a nice day

Hi Phaedrux,

Here is my firmware :
Board: Duet WiFi 1.02 or later (duetwifi102)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05 (2019-12-13b1)

And i did the update for DWC :
Duet Web Control 2.1.4

Still have the same issue.

Here is a gcode for exemple.
Cadre ventilo.gcode

Hello all,

Hope you're doing well in this special period.

My DWC, is showing the same height for all my objects. I tried slicing with simplify 3d & Prusaslicer, result is the same.

Do you have the same issue ?

Have a nice day.

Ok, does that mean that even DWC is showing the "default" file, it really the loaded file with G29 S1 P who is activated ?

Hi, i saved 3 differents grid matrix file at 3 different temperatures. Files have 3 differents names.
When i try to load a file with G29 S1 P"heightmap (60).csv" it weems to work (non error message), but when i go to the "height map" section, the graph and values don't change.

Then i tried to delete my "heightmap.csv" file and reboot. In "height map" section, graph is empty, that's OK. Then i try to load a file with G29 S1 P"heightmap (60).csv" or M375 P"heightmap (60).csv", nothing change. Map is still empty "file not found".

Thank for your knowledge.

I'll try to fine tune geometry of the structure, but it's not easy as we're talking of 0.5 to 0.1mm...
Isn't it possible to apply in the config a "dynamic correction" on Z trigger height ?

After a lot of small adjustments (on Y axes), i have something better but still not consistant :
Trigger height :

Rear left 0.47
Rear right 0.46
Middle left 0.48
Middle 0.40
Middle right 0.48
Front left 0.52
Front right 0.59

With my laser, i aligned the two Y bars. But i still have a trigger height of 0.92 at left, 0.64 at middle, 0.48 at right side.
I don't know how to manage that.

Here's the head :

Hi, I built a DIY hypercube and i experience some trigger height variations on my BL touch.
When probing on left side of bed, Z height is 0.96 and on right side 0.46.
Seems that head has a little tilt when traveling from left to right. I tried to mecanically fix that but it's really hard for me to do.

Is it possible to compensate Z trigger height ?
Thanks you.
