Having trouble setting the z offset
-
The files were all created with the configurator. The homeall.g has never worked correctly and when I look at the file, it is greek to me. When I home all, it starts with the x axis and the x axis starts grinding and slowly moves away from the endstop. I have to either cut the power of press the emergency stop to get it to stop. However, I can home the machine by homing each axis separately.
Please post your homing files.

The G1 X-305 Y-305 … is commented out so you need to remove the semi colon from the beginning of that line.
The next lines G1 X-305 and G1 Y-305 (course homing X and Y) don't have an S1 parameters so they will ignore the end stop switch. They should be G1 X-305 S1 and G1 Y-305 S1
The bed is being probed at the X0 Y0 position for the Z axis and while it will work, it's generally better to probe the centre of the bed
for Z home so you might want to add something like G1 X150 Y150 F6000 before the G1 Z-285 move. -
Thanks. Still learning the g-code world. Didn't even notice the first line was commented out.

No worries. Read and inwardly digest this and you'll become an expert https://duet3d.com/wiki/G-code.
Alternatively bookmark it for easy reference in the future. -
My home all is now working like it is supposed to. And my z offset is working.
