G38.2 not saving probe info into ESP3D?

Software / Firmware Jackpot Board / FluidNC
1

I have a touchplate off amazon with a depth of 14mm.

So when I probe G38.2 Z-115 F300 P14, it stops at the probe, but when I look at Zw on the dashboard, it is not reading 14 like it should? In the log, it says “Probe offset applied” but it seems to be not accurate.

This has resulted in a couple of times where I have tried setting the Z0 using the above command and when I run the program, it air balls the intended cut which is supposed to be at the Z-0.5 point to cut.

I am trying to flatten my waste board and I for whatever reason cannot get it now to record the right Z0 point. Am I doing something wrong here? Do I need to instead just break it into two commands like:

G38.2 Z-115 F300
G92 Z14

Thanks guys

G38.2 G90 Z-115 F300 P14
OR
G38.2 G91 Z-115 F300 P14

Depending of whatever workspace you are using

Which version of the WebUI are you using?

Try issuing ? at the terminal and see if that causes it to update.

If that fixes it, then likely your refresh/polling settings just need to be fixed so the UI gets the offsets back from FluidNC

Thank you, I am going to try that.

9046334, FW: fluidnc v3.9.1

I entered ? after probing and I got MPos: 0,0,-78.750, WCO: 0,0,-98.750

and then Zw was -78.750

Once I started the program, it had updated to the -0.5 like it was supposed to but it is still not cutting into the point I probed from…super weird!

In the milling basics, the start code has G1 Z10, I am using G0 Z20. Maybe i will try that? I took out the auto probing in program but maybe I will try adding it back in!

I just did the following:

In estlcam v12, I added back the probe gcode per the milling basics.

Changed my depth of cut to 1mm.

Started my code again, probe went fine, the program started and even at -1mm cut, IT IS STILL AIR CUTTING where I zeroed it.

I am at a loss to be honest and I dont know where to go from here. This is my gcode below.

lr4wasteboard1mm.gcode (14.6 KB)

Turns out, you shouldnt try asking your new CNC to go below what it has travel for…smh. dont do like me, be smart!

The entire reason why I was not getting any lower cuts was because the CNC was bottomed out. I cannot believe that I spent 2 days trying to flatten something I could not physically flatten.

Consider this cold case closed. Thank you all for all your attempts to help this situation. This was an error between chair and keyboard.
