Z-Homing, Error: Z probe was not triggered during probing move
-
no. it drops a tiny bit (2.5mm) as defined in the homing file(s) then moves up… but then never gets near the probe that is on the extruder head and just stops with that error: G28 Z Error: Z probe was not triggered during probing move.
If i wve my hand under the ir sensor i can see in the web console that it triggers so the ir sensor is working, the bed just never gets up to it to trigger.

My messy homeall script:
; Relative positioning
G91; Lift Z
G1 Z2.5 F3600; Move towards all axes endstops (first pass)
G1 X-999 Y-999 U999 F3600 S1
; Go back a few mm
G1 X5 Y5 U-5 F3600
; Move slowly to axes endstops once more (second pass)
G1 X-999 Y-999 U999 F360 S1; Absolute positioning
G90G91
G1 Z-999 S1 F3600
G1 Z3
G90G30
; Uncomment the following line to lift the nozzle after probing
G91
G1 Z5 F100

Scroll down to 1.19 and see if any of the
Upgrade notes from version 1.18.2:
apply to you.

Have you deleted the deployprobe.g and retractprobe.g files as described in the 1.19 upgrade notes?
The homeall.g file suggests that you have both a Z min endstop switch and a Z probe. This seems odd - have you? If not, see #1 at https://duet3d.com/wiki/Common_problems_and_their_solutions.
The command G28 Z runs homez.g, not homeall.g.

Yes, they have been deleted. Followed the guide to the letter as far as i can tell.
Running homez.g does the same thing. Bed never reaches the prob as if it was a soft limit of some sort.
Incase it helps:

OK maybe my install is broken:
When ever i try to make changes to any file like config.g, homeall.g, homez.g 9 times out of 10 i get:

What part suggests a min and max endstop? I only have an IR probe on Min (on the x carriage). I cant see where i have specified a max endstop.

I just ran M999, then homed X then Y, then moved Z up to just below the ir sensor then homed Z and it works fine. It is just failing to home Z when the bed is more than say 10mm away. It just gives up and states "G28 Z Error: Z probe was not triggered during probing move."
So it is this bit that does not work at all anymore….
G91
G1 Z-999 S1 F3600
G1 Z3
G90So if i home X and Y and move the ir sensor to X150 Y100 then send a G91 for relative positioning then G1 Z-999 S1 F3600 to send the bed up to the zmin endstop (ir sensor on x carriage) it does not move. This may be why it worked before and not now is G30 has a probe movement limit (as it seems to )...as it is the G30 command that is genrating that error.
Any ideas?
-
G1 Z-999 S1 says you are using a homing switch. G30 says you are using a Z probe. Follow the link I gave in my previous reply and look at the sample homez.g file contents for the two different ways of homing Z.

Ok, removing the G1 Z-999 S1 has resolved it. Thanks!
