Ender 3 + BL Touch = Mesh being generated but no print happening

My BL Touch seems to be working as expected, it's leveling

But when I run a print from Curia it homes, generates a mesh, and then the LCD displays "Stopped" and the printer stops moving, but octopi still shows that the print is printing.

I can post the GCode I've been trying to print if needed. All my axis seem to be working as expected, but nothing seems to be printing :(

Edit: This is the firmware config I'm using: https://github.com/jackmarketon/Marlin-bugfix-2.0.x-SKR-1.3/tree/master/Marlin

How is your z offset almost 15mm? Max range of a bl touch is about 5mm

That was what i needed to change it to to get my print head close to the bed... should I have raised the bed instead?

I bet you set that wrong.

Set it back to zero then home the axis with g28, then re get z offset after sending G1 Z0

That did it! Thanks!

Post your start gcode.

Also I concur with the other commentors question about the 15mm offset. That makes no sense.

When I get home tonight I'll grab it, it's mainly the Curia default start code + the two G codes for homing and generating the mesh.
