Probe not retracting

After updating to the most recent fluidnc and webgui my probe will not retract after making contact with the pad. I used to use the M5Dial for probing but that is broken so I’m using the webgui. I have retract set for 10mm but the probe just stays on the pad after making contact.

That problem has been around for ages, mine actually goes down. The idea is to implement it in your gcode, that works.

That’s a shame. So the “Retract distance” in the webgui doesn’t inject the code automagically? The other settings in the probe window seem to update. feedrate, etc.

I don‘t know what exactly the problem is, only my secondary machine is running the Jackpot. But the answer has always been: it does not work. Bummer, if you ask me. :slight_smile:

I’m pretty sure @Michael_Melancon fixed this but I can’t find the thread. I think there’s another setting you have to change.

Curious. Would love to see it. On the M5 Dial it just did what I needed it to.

You need to make sure the probe post command in your settings is set to this:

G10 L20 P0 #selected_axis##probe_thickness#;$J=G91 G21 F1000 #selected_axis##probe_retract#

I fixed the default, but if you already had a value there, it would not get overwritten on upgrade

and actually… there’s another bug there because the feedrate is ignored too

Amazing!! Thank you.

So I think it should actually be

G10 L20 P0 #selected_axis##probe_thickness#;$J=G91 G21 F#probe_feedrate# #selected_axis##probe_retract#

but I haven’t tested that

oh…well… maybe not. (sorry…long day…)

that probe feedrate probably is taken into account on the probe itself…

however…

If you also want it to be taken into account on the retract, then I think this should work

G10 L20 P0 #selected_axis##probe_thickness#;$J=G91 G21 F#probe_feedrate# #selected_axis##probe_retract#

otherwise, the first one is correct and you can change the F1000 to whatever you want the retract speed to be

G10 L20 P0 #selected_axis##probe_thickness#;$J=G91 G21 F1000 #selected_axis##probe_retract#

Thank you again for the quick replies. Amazing group of folks we got here. :slight_smile:

Hi Mike. This seems to be working well now.
This did not retract after probe contact:

G10 L20 P0 #selected_axis##probe_thickness#;$J=G91 G21 F#probe_feedrate# #selected_axis##probe_retract#

This one worked though:

G10 L20 P0 #selected_axis##probe_thickness#;$J=G91 G21 F1000 #selected_axis##probe_retract#
