calibration IR probe RRF3
-
First of all, I want to say that I have absolutely nothing against this forum and the people who make it live ... I blame myself and especially not the community for doing its best.
You should also know that I do not speak English and it is very difficult to make yourself understood or to understand you in your answers.
My issue is the following :
I am using a Duet 2 under RRF3.1.1. I absolutely cannot get my Double Z (Z and U) to work independently to level my bed. One of the Z motors is connected to Drive 2 and the other to Drive 4.
When I do a G32, I see the axes (M671) which restore my possible inclination, it works without any problem. On the other hand, for the future with the M557 which runs my two motors, but symmetrically so they do not correct anything since they move equally. I think my whole configuration is corrupted now by dint of modification.

M574 Z1 S2 P"io2.in"
You do not need this. io2.in does not exist on your duet 2. and you don't need to define a z axis endstop if you're using the probe.
@Rudy2A said in calibration IR probe RRF3:
Double Z (Z and U)
You do not need a U axis at all to do leveling using G32/bed.g as you have now.

Remove the U4 and all references to the U axis in M92, M350, M566, M203, M201, M906, M208. Remove the P3 as well. You don't need it.
M671 X-58: 317 Y132: 132 S10Remove the space after :Once you have done all of that, G28 should home all axis, and then G32 should perform tilt correction.

Apparently, it seems to be out of order (to watch out for) ...
I still have a slight problem calibrating my probe (mini IR).
When it raises its value.=>>
"Nozzle in the center of the bed (usual temperature)
Put the nozzle in contact with the tray (or the sheet of paper)
G92 Z0 (Z = 0)
Lift the 5mm nozzle (G92 Z5)
G30 S-1
Read the z value
G31 Z xxx"I get a height of 2.74 and if I indicate this value G31 Z2.72 my first layer is too crushed ... On the other hand if I go down to 2.62 in manual G31 Z2.62, it is good. Is such a Delta normal?
I am in doubt about my order for the probe, does this seem correct to you?

yes, the first step is just to get a close value.
fine adjustment should always be made afterwards. -
Thank's @Veti
A small clarification on my values.
If I adjust my leveling on 2 points, my first coat is impeccable. (probe at the four corners of the bed) M557 X11: 250 Y11: 252 P2
If I adjust my leveling on 3 points, my first layer is much too high (probe at the four corners and in the center) M557 X11: 250 Y11: 252 P3
Please note that this is the same part that I am printing and no changes have been made.

It depends if you bed is perfectly flat.
If true, g32 is enought
if false, g32 + g29 is needed. -
In both cases I do a G 32 + G29, all in a bed.g file

i dont think that the bed.g should contain a G29. or a M557 .
if you cant G32 + G29 you should create a macro
-
You may want to add a single G30 at the center of the bed after the G30 P0 G30 P1 lines so that any change in height caused by the tilt correction is captured before the heightmap is created.

I did not understand everything ... Like that?

@Phaedrux Thank you, I'm testing ...
