Probe / Touchplate - Not sure how to Z level with it

LowRider CNC Troubleshooting
1

So I’m using the main build guide and I just did the belt adjustments and square test. I’m within a 1/32 or less of square and moved onto the Z-Leveling.

I have a probe but when I use it nothing happens. Not sure if it’s a set of commands or not? Basically if I touch the bit, I get the LED to light up but nothing in the GCode area comes up.

I homed Z, ran G10 L2 P0 Z0 and got an ‘Okay’

Started bringing it down slowly but when I got to the touch plate nothing happened. So I moved it up 10mm and back down 10mm while touching the plate to the bit but it never stopped it. Not sure what I am doing wrong so any help would be appreciated.

You need to run a probe gcode command.

For Marlin, it is G38.2 Z,0, followed by G92 Zn (where n=probe thickness).

Not sure what the syntax is for FluidNC

Thanks, I think I know what to do now. I’ll give it a shot this morning

Make note of the current Z position, do this at least 3 times on each side and average the position.

That is from the build guide. Is that for each point you measure? How many points should you do? It almost seems that you only do it once, at Y0 and then Y1

Another thing to keep in mind is that when you run a probe command it has to be less than 20mm above your project surface. That 20mm may not be the spec. If I’m wrong somebody will chime in. I just remember it confused me until i figured it out.

On the web interface you just push ‘probe’.

it’s adjustable in the config.
