Error 1 expecting Gcode line 1

Software / Firmware

The following program was hand written in NC Viewier and runs fine in that environment. My MPCNC Primo has been working fine with tweaked Fusion 360 programs (removing residual spindle speeds etc.)

My machine won’t get past line 1, reporting back an Error 1 Expecting a Gcode letter. Help please?

Forgot to add controller is the V1 Engineering Jackpot controller purchased late last year.

That looks okay to me, Are you sure there is not a blank line or line numbers or something?

Can you post the contents of the terminal or FluidTerm when you get this error?

Are you trying to run this code from SD card using the WebUI, or using a sender program?
If a sender, which one?

Did the forum line-wrap this, or is this the actual output? My guess would be the “1/2 revolution” line needs commented out.

Thanks all for your replies.

Taking a working program I tucked my code for the new program in after the first few lines, using Notepad as the editor. It worked

Desiring to make some tweaks using NCViewer because it has line counts I ‘saved’ that (it downloads the file), but subsequently it didn’t work.

Same changes made in notepad did work. So convinced that the download saving process from NCViewer must be the problem.
Thanks again for taking a look.
