Please paste config.g in use the code block (</> icon in the text formatting menu), to format it

I have edited your post to paste in the contents of the file in a code block. this makes it much easier for people to help you.

from the documentation here:
https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_auto_levelling#axis-levelling-using-endstops

When homing, RRF3 will home both axes, and stop each motor when each endstop is triggered. Note that DWC and M119 will only show one endstop per axis, but will show the axis endstop as triggered if either switch is triggered. So you can test them by triggering one at a time.

That is true for the object model as well.

Awesome thanks!!

@Snyggis-0 said in Bed Leveling Probe - Liquid Cooled Hot End:

Is the general idea to get rid of the z switches, as this is now done with the touch probe?

Not especially, it's just that probes can measure at any point on the bed, are very accurate and repeatable, and can be used for bed levelling and creating the bed mesh.

The best use for endstops on Z, I think, is to have them at the maximum end. If you lose power during a print, and want to resume, but the Z has moved, you can home Z to the maximum end (so the nozzle doesn't hit the print if you try and use the probe to home), and then resume the print.

@droftarts

I absolutely agree with your thoughts if your concern is power failures.

I don't like power failures for variety of reasons.

So my approach was to install a propane powered generator with automatic transfer plus dual-conversion UPS units with enough runtime to power the printers until the generator kicks in, which is typically 30 seconds.

Overkill? Probably but its nice to have power that doesn't go away because a storm rolls in. I will admit that I only have enough propane in the tank for 10 days, so a serious power outage due to say, storm damage, may mean I will lose power.

Moving the endstops is a much cheaper solution. 😁
