@droftarts I am not using that comand, it was there from a configuration file example.

Okay that’s what I will do, move to the Z probe pin.

Here is all the info, I did not know about M98, it seems very handy.

Hello, I connected the DC42 IR sensor to my board using the Z0 endstop connector, and I can see that electronically the power (3V3) and connection is good (in standby the status led of the sensor is on, when I put something nearby the sensor the led goes off, also, the led on the motherboard has the inverted state of the led on the probe).

The issue remains with the config file, in which I have the following lines:

; Endstops
M574 X1 S1 P"xstop"                                ; configure active-high endstop for low end on X via pin xstop

; Z-Probe

M558 P1 C"zstop" H5 F120 T3000  ; Z probe connected to Z endstop input
G31 P500 X0 Y0 Z2.5

And I can't seem to figure it out. On the first page under sensors I don't even have a "Probe" sensor. Also, if I run G31 in the console it returns:

Error: G31: Invalid Z probe index

Thanks guys, it seems to be what I was looking for!

I am looking for a way to test a few Z probe types for their accuracy but to my surprise I could not find a command or example macro for this. In klipper or marlin there are dedicated functions for this.

I know from the probe calibration page that I can raise Z a few millimeters then lower Z until the probe is triggered and the height will be reported, but could I store this value in a list and repeat the command 10 times? Then (not necessarily but would be nice) do some math calculations with the numbers to determine mean value, standard deviation.

Any of you have an idea of this can be implemented?

@jay_s_uk This seems interesting! I'll give it a look and try to replicate the project.

Hello, I saw that it's possible with the Duet Maestro to keep the originak LCD panel and controls from the Ender 3 printer. I would like to do the same with my Duet 2 WiFi board.
Could I manually adapt the hardware pins with a connector and then activate the LCD support from software? How can I find out what pins do I need.

Thanks for your help!

@Phaedrux Yes it is a clone, that's the name, 3D Touch. Everytime I wonder if the probe is not the issue, and I'm not sure, I plan to replace it with a IR-probe to clarify this unknown variable.

@fcwilt the phisical offset is 2.9mm in reality

Okay I added the ^ in front of zprobe.in it should be more robust in triggering the probe.

Still for me it's not about that, it is some offset stored somewehere in the software, or my probe might be damaged.
Because right now I had to recalibrate the probe and increase the Z offset from 2.95 to 3.9 and this seems impossible.

Thanks for your input. the Z-probe code is taken from the duet page example, M307 is there to release the H3 pin which is by default by heater 3 and not cause any problems.

To greate the mesh I manually ran once first HomeAll then Run Mesh Compensation (G29) from the DWC.
Then I can see the map in the Height Map page, I assume G29 S1 is loading that map that is shown in the visualizer. Or am I wrong?

My printer is configured and printing well, it has dual motors for Z and I have a 3d touch probe to home the Z axis, do auto bed leveling and the bed mesh.
I have a big issue that sometimes, something happens and the Z height gets messed up, the result is that the printing starts at a few milimeters in the air above the bed.

Lately I was just homing the printer and loading the previously measured bed heigth map, and still the issue happenend.
I have added all the code that migh get involved in a print procedure, homing, stoping the print.
