Dual Endstops with Euclid

Adamfilip

I have a Z endstop switch and a Euclid probe

I would like them to work together with Z endstop basically being a backup incase something doesnt work properly with Euclid mounting.

would something like this work?

M574 Z1 S1 P"!zstop"   ; Z min active high endstop switch
M558 K0 P5 C"!zstop+^zprobe.in" H4 F500 60 T9000 A1 S0.01

This is my current config

; Endstops
M574 X2 S1 P"!xstop"   ; X max active high endstop switch
M574 Y2 S1 P"!ystop"   ; Y max active high endstop switch
M574 Z1 S1 P"!zstop"   ; Z min active high endstop switch

;Euclid Settings
M574 E1 S2  
;
M558 K0 P5 C"^zprobe.in" H4 F500 60 T9000 A1 S0.01      
G31 K0 P500 X0 Y-39 Z1.90             
M557 X10:290 Y10:290 S40                      ; define mesh grid S86 =  Spacing 86mm

This is my homeall

G91                    ; relative positioning
G1 H2 Z5 F6000         ; lift Z relative to current position
G1 H1 X300 Y300 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 H2 X-5 Y-5 F6000     ; go back a few mm
G1 H1 X300 Y300 F360  ; move slowly to X and Y axis endstops once more (second pass)
G1 H1 Z-205 F360        ; move Z down stopping at the endstop
G90                     ; absolute positioning
G92 Z0                  ; set Z position to axis minimum (you may want to adjust this)
G1 Z5 F3000
G1 X150 Y150 Z25 F3000

@adamfilip

Since you have a Z endstop why not simply use it alone for homing Z and use the Z probe only for G30, G32 and G29 commands?

@adamfilip I would advise against that. Euclid mounting is extremely reliable, and with the use of the conditional g-code checks you will get a warning if not attached.

You can use the Z-endstop to set 0, then use the probe to 'reset' Z=0 with a G30 S-2 command to redefine Z at the probe trigger height

OR

You can use Euclid as your probe and endstop, and have the hardwired Z-endstop work as a high limit switch via M581 to be your 'failsafe' in case of a malfunction.
