Setting Z probe and mesh compensation in config g

Vladimir

Good afternoon
Please help with the Сonfig file for Duet Wi Fi version 2.03. generated by RepRapFirmware Con.Tool v2.1.6
I assembled a Cartesian printer where XY moves in the same plane with ball screws and 3 step motors
the Z table is lowered with balls crews and 2 step motors. I connect inductive sensor NPN normally open. The problem is that I can’t level table with Z ptobe and I can’t get a mesh bed compensation.
Please help me what am I doing wrong
kind regards

@Vladimir said in Setting Z probe and mesh compensation in config g:

M574 Z0 S0 "Z-stop

You need to remove the above setting and just leave the M558 command, my RRF2 setting were :

; Endstops - these are for standard standard switched X low, Y high, active low

M574 X1 Y2 S0 ; Set active low endstops

M558 P8 I1 R0.5 H5 T24000 F250 A0 S0.04 ; Set Peizo - P probe type, I Invert, R recovery time, H dive hight, T inter-probe-point speeds, F Probing Speed, 3 Dives , S calculated difference

@Vladimir Please send M115 to your Duet and post the reply. Your config.g is for RepRapFirmware 3, not 2.03.

Assuming you are using RRF 3, your endstop configuration is wrong. Your have:

; Endstops
M574 X0 S0 "X-stop"
M574 Y0 S0 "Y-stop"
M574 Z0 S0 "Z-stop"

See https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_Set_endstop_configuration
'X0' 'Y0 and 'Z0' disables the endstop, so you have no endstops enabled.
'S0' sets the endstop type to active low endstop input. If you are using microswitches as endstops, using active high (NC/Normally Closed) is recommended; see https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Microswitch.
The input pin needs the parameter 'P', eg P"X-stop".

Change to this and test:

; Endstops
M574 X1 S1 P"xstop"                            ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop"                            ; configure active-high endstop for low end on Y via pin ystop

For the probe, as @Dr_Ju_Ju said above, change the Z probe configuration. Also, you will need to check your homing gcode files, particularly for Z. They may be using G1 H1 Z moves, it should use G30.

you are right I send M115 - the reply: RRF for Duet Wi Fi/ Ethernet Firmvare_version:3.0 Electronics: Duet WiFi 1.02 or later + duex5 firmware_date:2020-01-03b3

So far,the movements of top portal and z limited by mm and only one end stop
But adjustment of sensor and compensator I do not understand yet.

Maybe I 'm in the wrong thread having a discussion and it needs to be moved to "Firmware Installation" if yes moderator tell how to do it thank you

@Vladimir M122 is just reporting that no compensation is in use:

I see you have M557 in your config.g. Send M557 at the console, what is the response?

@Vladimir Another option; send M98 P"config.g". This will run your config.g and show any errors.

Your endstop configuration is still wrong, particularly as you are missing 'P' in "xstop". Comment out all endstop definitions with ';' if you don't have them fitted.
