Hi 3DStyle,

mstrens told me it is better to use this one :

G91 G21 ; (Relative position in mm)
G38.2 Z-30 F100 ; (Search of the probe on 30 mm speed 100, if not found after 30 mm Alarm GRBL)
G0 Z1 ; (Back 1mm)
G38.2 Z-1 F10 ; (Searching the probe for 1 mm, slower, speed 10)
G10 L20 P1 Z19.3 ; (Adjustment of the Z offset according to the thickness of your own probe – 19.3 mm in this case)
G0 Z3 ; (back 3mm)

See ya

Hi HTheatre, thank you for the suggestion.

What does the command G10 L20 P1 do?

LOL, I am not sure It's refer to the relative coordinates if I don't miss me.

mstrens a écrit : ↑06 avr. 2020 13:43 A noter qu'il n'est pas sûr que la ligne avec G92 soit la meilleure commande Gcode à utiliser.
Il faudrait chercher un peu sur le web car je pense qu'on conseille de mettre à jour l'offset correspondant à G54 notamment parce que ce setup reste mémorisé après un redémarrage et parce qu'il arrive que certains programmes définissent aussi l'offset G92.

mstrens a écrit : ↑06 avr. 2020 16:53 En fait la commande à employer est la suivante:
G10 L20 P1 Z19.3
(fixe la position courante en Z du système de coordonnées G54
à 19.3)

(Deepl translation)

You should search a little on the web because I think it is advisable to update the offset corresponding to G54, especially because this setup remains memorized after a reboot and because some programs may also define the G92 offset.

(sets the current position in Z of the G54 coordinate system.

Haha, that's hilarious

Okay, I'll try it tomorrow.

In fact, I hope it will solve an issue I'm always facing with - lets say that I'm about to start a milling job.
Before I start the job, I do a Z probe with the G-code I wrote here yesterday. Then, I press on the SD card button and choose the milling job file. I cancel the job during operation because of an issue/error, fix the issue, and then restart the milling job. The machine should start the milling job in the WPOS of XYZ. The machine starts correctly in the XY coordinates, but for some reason, the Z height is higher then it was initially, when I did the Z probe, and the milling job is basically milling in the air, above the material. I need to cancel the job again, and do a Z probe.

I hope this Z probe G-code will fix this.

Yeah I know I think too. I have only copied/pasted

Any update regards this bug?

Hi,

I did'nt checked it because I'm quite busy the week (repairing a house) and the sun is back so I'm more outside during the weekend/gardening, moreover I'm making a RC lawn mower :p.

Hi guys, any updates?

Anything?
