Microswitch Z-Stop Config and Home File

Merlin246

Hello,

I am having some trouble configuring my Toolchanger z-stop (somehow the config file was erased and I don't have a backup). The printer uses a microswitch for the probe.

Board: Duet 2 Wifi with Duex Expansion
FW: 3.4.3 (2022-10-05)

Config and home-z files below:

; config.g
; Endstops
M574 X1 Y1 S3	 			; Set X / Y endstop stall detection
M574 C0		  			; No C endstop

; Z probe
M558 C"z_stop" T50000 A1		; Define probe
M574 Z1 S1 P"!z_stop"			; Set Z endstop to active low
M557 X10:290 Y20:180 S40 		; Define mesh grid
G31 Z0					; Set trigger height

;homez.g
G29 S2;

G91 					; Relative mode
G1 H2 Z10 F5000				; Lower the bed
G90					; back to absolute positioning

G53 G1 X150 Y100 F50000	                ; Position the endstop above the bed centre

M558 F3000
G30
M558 F300
G30

G29 S1;

With this homez.g the following error occurs:

Error: in file macro line 12: G30: Z probe 0 not found
Error: Z probe 0 not found
Error: in file macro line 14: G30: Z probe 0 not found
Error: Failed to home axes Z

Trying to figure out what I'm doing wrong but I'm hitting a wall. Any help would be appreciated

@Merlin246 Something like

M558 P5 C"zstop" H5 F120 T3000

should suffice to configure your Z-probe. Remove the following M574 line.
When you've made that change to config.g, run M98 P"config.g" and check for potential errors.

@chrishamm thanks for the reply. Works great, I owe you a beer.
