RCG3

I guess the Z-10 sends the machine to the “position Z=-10” instead of down 10mm. It’s making more sense to me if that’s the case.

Thanks SteveD! I’ll have to work on this tomorrow. So by homing the machine I’m setting G53 to 0,0,0, right? Then by setting g54z=0 I’m essentially making g53 and g54 the same? What does G28.3 Z0 do right before running the widget?

Sorry for the dumb questions. I have a lot to learn.

I did what you said to do and it went down like it’s supposed to. I ran the macro in CNCJS and this is what it sent.

; Z-Probe
G91
G38.2 Z-10 F50
G90
; Set the active WCS Z0
G10 L20 P1 Z19
; Retract from the touch plate
G91
G0 Z4
G90

I set g54z=0 and now it goes down! Thank you so much!! Can you explain why that was causing a problem? Looks like a learning opportunity to me.

I need to slow down! Yes, I get the same results when I enter the G38.2 Z-10 F20 from the command line in the console.

Thanks for your reply! I’m not sure how to do the cloud drive and link. Sorry for that. I can cut and paste though. I hope that’s okay.
