I still can't reproduce the problem you describe, but I've found an error in your GCode. You have this in config.g:

M208 X0 Y0 Z0 S1 ; Set axis minima

The relevant commands in your GCode file are:

G0 X14.3143 Y50.0000 Z0.0010
M3 S200
G1 X83.3143 Z-0.0010 F1000.0 S200

The last G1 command has endpoint Z=-0.0010 but you have set the Z minimum to zero. So that command is to an out-of-bounds position and it won't be executed. You should get an error message in the console.

@dc42 yep i get an error only when i dont drop my z down after it has been homed so home z, drop z down by about 15 then set work zero then i run the g code.

Do you have a g code you would like me to try ?

Shall remove the z comands and see if it will work?

@dc42 did you view the videos they show my issues?

dc42

Yes I looked at your videos. What I think is happening is that heater 2 has become re-enabled, and the heater monitoring system is turning it off.

Please check that you do not have a M307 H2 command in config-override.g.
Please run M307 H2 with no additional parameters and report the results.
Please attach to your next post your config.g and config-override.g files, also a simple GCode file that should cut out a square or rectangle and that demonstrated this problem. Do not do any Z movements in the cutting moves.

@dc42 you are amazing there was a M307 H2 in the config override g, i removed it and rebooted and all works like a charm.
i have included my override g just to see if there is anything that shoudent be there.

the line g code now works i owe you a drink
