[Solved]Confused again about Z-homing Orion probe
-
Hi
I have my Orion quite a while now, but chang from having max z/u endstops to using the probe as z-min.I do this to save time homing.
I have this in my config.g
G31 X0 Y0 Z0 P100
M558 P5 I1 R0.9 F500 X0 Y0 Z0and homez.g
;homing min using probe
G91 ; relative positioning
G1 S2 Z10 F6000 ; lift Z relative to current position
G90 ; absolute positioning
G1 X145 Y145 F6000 ; go to first probe point
G30 ; home Z by probing the bed; Uncomment the following lines to lift Z after probing
G91 ; relative positioning
G1 Z10 F100 ; lift Z relative to current position
G90 ; absolute positioningHowever after homing it z shows 15.7mm when probing G30 S-1 after homing it always shows 0.7mm..
I don't understand where the 0.7mm comes from
as result my prints start to close to the bed(0.6mm)
What do I do wrong? -
If I manually perform this from the console and then home z it works
G31 X0 Y0 Z0 P100
M558 P5 I1 R0.9 F500 X0 Y0 Z0 -
Ok G31 returns
G31
Current reading 0, threshold 500, trigger height 0.70, offsets X0.0 Y0.0so that explains..but where is the 0.7 coming from? I don't have it in my config.g or any other file..
-
Think I found the reason G31 before M558 seems to ignore the G31 setting. Placing it after M558 did the trick

G31 X0 Y0 Z0 P100
M558 P5 I1 R0.9 F500 X0 Y0 Z0The G31 should come after the M558 in config.g if it isn't already.
What firmware version?
M558 X0 Y0 Z0 is deprecated, remove those.
Can you post your entire config.g?

thanks for the M558 comment..will remove that
But yes placing G31 after M558 helps. I cannot find where that is stated though...... -
