Bad Character Gcode error

I have designed a clock face in Easel and have compiled the Code to run with CNCUSB machine.
When loading loading Gcode I get the following error:
Bad character ? (19) Line 1.
I have tested and run applications from Easel Apps no problem.
Any help would be appreciated as I am new at this

Thank you

Open your gcode in a text editor, and get rid of the character on Line 1.
What did you use to generate the gcode?
If that doesn’t work, share the file here.

Here is a list of those Gcodes that are supported with GRBL. I always delete the $ sign, any P codes, anything that doesn’t control the router, like fluid on/off, router on/off, because I don’t use those things.
