Error: in file macro line 41: G30: Z probe 0 not found

csoup50

I have been running this machine for a while and then updated to the new beta 3.5 beta 2 and now I cant seem to get the homing to play nice. I was on 3.30 prior to the update and everything was working fine. Its driving me crazy and I cant seem to find the answers, Ive tried so many things but nothing seems to solve it. Thank you for your help!!!

M574 Z0 S1 P"!zprobe.in"                       ; configure Z-probe endstop for low end on Z

Remove that line from your config.g

Your homeall is confusing because it uses commands for a Z endstop, but then also calls G30 to use the probe.

What is your actual intention?


; Move Z down until the switch triggers
G1 Z-280 F4000 H1 ;CC Added 1000 to F

; Absolute positioning
G90

; Tell the firmware where we are
G92 Z-0.1

; Uncomment the following line to lift the nozzle after probing
G1 Z5 F900 H2 ;CC added 

;M558 R1 H5 F2000 T6000 

G30   ; Singe z Probe the bed at the current XY position, when trigged set the z coordinate to the probe trigger height

Your config isn't correct to use a z endstop, so just simplify that section to use only the probe with the G30.

@Phaedrux Ok I removed the M574 for the Z. What do you mean its confusing, Im not seeing what you are. Its me not you.

My intention is to lower Z, home x y and then home z with the probe.

Phaedrux

The error you were getting was because you were trying to use the zprobe input pin in the endstop section, and then use it for the probe input itself.

Why lower Z the Z first before XY and then home Z again?

@Phaedrux Ok, I get what your saying. it seemed to be the only way to alleviate the errors. After removing the M574 I now get these errors. Error: Failed to enable endstops
4/14/2023, 8:10:11 PM G28
Error: Pin name needed for switch-type endstop on Z axis

To your second point, I want the build plate to drop slightly to reduce risk of dragging on the build plate before X and Y home.

Phaedrux

You'll need to remove those G1 H1 Z moves to stop those errors.

To get some clearance for Z first that's much easier. Just add a G91 G1 H2 Z5 move before homing XY to raise the Z by 5mm.

@Phaedrux well it looks like you got me on the right track. I commented all those out as you said and added the command. Now im not getting the errors that I couldnt figure out! Thank you so much!!!
