G28 ;Home
G29 S1
G1 Z10 F6000 ;Move the platform down 10mm
G92 Z0

If this is your start gcode in the slicer why does it use G92 Z0 to set the Z0 point there? It makes no sense. It homes all axis, loads a heightmap, moves down 10mm, sets that point as Z0 arbitrarily, and then does a prime line.

@dakingofhearts2003 post your config, homeall and homez and a photo of your hotend so we can see our probe

Let's see what's going on under the hood.

@phaedrux You can close this one out but i have another question about how to level the bed manually. I cant use g32 if i dont have multiple z motors can i ?

You can use this to make a manual adjustment assistant if you don't have independent motors and drivers.

@phaedrux in the probe section i was trying to diagnose a bl touch not responding issue in the dark i figured i must have put the connector on in reverse because i heard a pop and then no more wifi or usb.

one comes out the right size on my tevo but the duet board died and before that would always disconnect

I didnt know i was going to need to be an engineer to change boards and firmware i see why people buy prusas

I can partly understand your frustration, as RRF and Duet boards are getting more and more sophisticated
They offer more options, but also ask more from the user. Like reading manuals and listen to experienced users....

@Phaedrux i'm going to try the negative numbers and see what happens

i assure you everything is correct

And yet your nozzle is 5mm above the bed. 🤔

Please verify your firmware version with M115.

If you send M98 P"config.g" do you get any error messages?

Your config is basically correct for a BLTouch connected to heater pin 3 on the expansion port provided you're actually using RRF3.

M558 P9 C"^zprobe.in" H5 F6000 T6000 ; set Z probe type to bltouch and the dive height + speeds G31 P500 X-39 Y14 Z5 ; set Z probe trigger value, offset and trigger height

G31 Z5 is a very high trigger height. Be sure to do a calibration measurement once it's actually working.

M558 F6000 is very fast probing speed for the BLTouch. F120 is more appropriate. Your Z axis speed is currently limited to 180mm/min so it can't probe faster than that, but that's really slow for normal movement, might want to change to M203 Z600.
