How to do simple Z homing with endstop?
-
I need to revert my Cartesian hardware back to simple Z endstop homing. I have a working mechanical Z endstop switch to set the Zmin like I used to with Marlin. I figured I would run through the configurator and generated the config line I needed, piece of cake.... test the switchs via M119, they all check out.
The result is I get is an interactive menu of sorts to set Z height. I just want dumb, stupid, Z endstop. Does RRF do this?
Here are my config lines-
; Endstops M574 X2 Y2 S0 ; Set active low Endstops M574 Z1 S1 ; TEMP SET ENDSTOP Z MIN ; Z-Probe ; M574 Z1 S2 ; Set endstops controlled by probe ; M558 P8 I1 R0.4 H5 F420 T6600 ; Piezo Probe settings M558 P0 I1 R0.6 H5 F840 T7200 ; TEMP Change probe to 0 for no probe ; G31 P500 X0 Y0 Z0.0 ; TEMP comment out for no probe -
you will need to change the homing scripts as well.
i.e. homez
G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G1 S1 Z-205 F1800 ; move Z down until the endstop is triggered
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)and homeall
G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G1 S1 X-235 Y-215 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 X5 Y5 F6000 ; go back a few mm
G1 S1 X-235 Y-215 F360 ; move slowly to X and Y axis endstops once more (second pass)
G1 S1 Z-205 F1800 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z to axis minimum (you may want to adjust this) -
DHO! I did not think of that.
@Veti THANK YOU!
