z probe wont respond to G31

ziggymanpopo

Is G 31 the place i need to set my off
set?? Im not sure at all

Phaedrux

Do you have a G31 in your homing files or beg.g?

ziggymanpopo

No more entries in any other files that i know of.

dc42

Is it the height after homing Z that isn't changing? If so then that may indicate an error in your homeall.g and/or homez.g files.
What Duet and firmware version are you using?

ziggymanpopo

i believe the corect anser to be ver1.12
also remeber ihad to reload my www. file
so ver1.12. with the v2 dwc interface. would that be correct?

heres the config g < home all< and the home z files for you to see

( ill remove G29 S1 )

also just found this file called bed g.

not sure, but is this for slicer start code??

ziggymanpopo

will this also add another error for z offset or ??? is this one o k in its separate system fie

ziggymanpopo

lets start over new thread
re ask the question

this is where im at
duet reports z at 12.75 after homeing
trigger height is at 7.75
zerro is at is at 6.30

during a print the duet throws back the Z tool position as 1.42 with the nozzle burried in the glass
in my mind all Entries are a positive #

Z-Probe
; M558 P5 H5 F100 T2000 ; Set Z probe type to capasitive and the dive height + speeds

G31 P500 X-42 Y-5 Z7.75 ; Set Z probe trigger value, offset and trigger height - is Nozzle hoger

ziggymanpopo

is this my error ...Z7.75 should it read Z-7.75 is it a flipin - that been hanging Me???

aidar

I dont know if it is related to your problem or not, but you should remove G29 S1 from config.g. You can not enable mesh compensation before homing. G29 should come after homing, not before.

ziggymanpopo

i believe its commented out wouldn't that do the same

aidar

@ziggymanpopo said in z probe wont respond to G31:

; Automatic saving after power loss is not enabled
; Custom settings are not configured
; Enable Bed Leveling
G29 S1 ; Enable Mesh Bed Leveling

Does not seems to be commented out.

ziggymanpopo

; Automatic saving after power loss is not enabled
; Custom settings are not configured
; Enable Bed Leveling
;G29 S1

ziggymanpopo

think i did it right after im just stumped?? are my settings right ??

ziggymanpopo

other than that ??

ziggymanpopo

offset suppose to be a neg. # instead of pos #...maybe????

aidar

Only thing i recommend is, for me changing Z offset works if i change it in config.g G31 command and restart printer. I know it should work "on the fly", but for some reason sometimes doesnt work for me.

aidar

And no, offset should be positive, until your probe is not your nozzle like smart effector or piezo something...

ziggymanpopo

@ziggymanpopo said in z probe wont respond to G31:

G31 P500 X-42 Y-5 Z7.75 ; Set Z probe trigger value, offset and trigger height

so note no neg for Z

ziggymanpopo

???? not sure the instructions said pos triger hieght all other sensors other than toutch nozzel ???
