Any idea why my machine is stopping after about 25 lines. I am receiving a “expect command letter” error. I do not see an issues with the gcode or commas or periods. The preview looks great - It just stops!

Using Chilipeppr and Grbl with a simple line cutting program.

Any help would be greatly appreciated

Thanks

Here is the code
