Help with if then loop
-
I'm converting my Z probe to a Klicky style microswitch. I'm waiting on parts to finish the dock/undock of the switch. I would like to be able to remove the magnetically held switch by hand until the parts come in. I would like to write a macro to check if the Z probe is 0 then loop back and check again. If the Z probe is greater than 0 then proceed. This sounds simple and I'm sure it is but I'm having trouble with it, running f/w 3.2. Could someone show me how to write this code, thanks.

@luckyflyer there's no conditional gcode or object model until 3.3. I suggest you upgrade your firmware to 3.4 now it's stable and then come back
-
@jay_s_uk I'll do that today.

After you get your fw updated, check this doc page for details of programming capabilities in 3.4. The if statement is right in there.
And if you are waiting for a user action, you might consider using an M291 that can pause code execution (blocking) until the user responds.

@mikeabuilder seems like you forgot adding the link. Here it is: https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands

@luckyflyer, this is how I check that the Klicky was indeed picked up. The probe value changes between 0 and 1000. Not sure why I use > 250 and not > 750 but it may not matter.
M400 G4 P250 ; Wait 250ms if {sensors.probes[0].value[0]} > 250 echo "Error: Clickey not picked. Value: " ^ {sensors.probes[0].value[0]} M112 ; Emergency stop. echo "Clicky pick done" -
Thanks all, I have 3.4 up and running. I'm now struggling with getting mjpeg-streamer working again. Final parts needed for docking the switch will be here Monday. I'm looking forward to having my printer back online.
