@droftarts Thank you both for clarifying. It makes a whole lot more sense now.

Was wondering if someone could help clarify something for me. I have searched high and low and cant find a clear answer. In the G31 gcode command what exactly is the Pnnn Trigger value? I have found comments such as "when the probe reaches this value the probe is triggered". If I enter G31 P500 command what exactly is the 500? 500 what? Is this a probe sensitivity setting like in a M672 command? Where would I find what this P setting parameter should be for my setup? I have an SE300 hot end (with strain gauge) on a RostockMAX v3.2 printer.
Thanks for any help

Thanks Jay for the quick reply. Sounds like I am good to go then.

Hello
I have just updated my firmware to the 3.4.4 version and I noticed that I do not have the homing buttons for the individual axis in this machine movement section. I have the Home All button. My printer is a RostockMAX v3.2 delta printer. I thought I had the individual axis homing buttons prior to the upgrade but I am not sure. Should I have these buttons even with a delta printer or are they just shown for cartesian and CoreXY printers.
Thanks for any help
