Trying to figure out what is giving the Bad Command error
-
Can you upload the file itself so we could check it in a text editor?
Another thing you can try is to send each command copy and pasted from the file in the gcode console and see if any give an error.
M572 S0.000000
Maybe try fewer zeroes?

It doesn't seem to cause any problems other than driving me nuts not knowing what's causing it.

I have tried commenting that line out and it did not fix the error.

Upload the homeall. and bed.g as well.

M104 S215 T0 ; start preheating hotend
I don't think M104 takes a T parameter, but I don't think it would complain about it...

I meant the actual file so we can check for bogus characters.

Were you able to test this one?

Do you get the Bad Command error just once, or multiple times during the print? If it's multiple times then we probably need to see the whole file.

@dc42 There's the whole file.

HxD revealed that yout GCode file has some non-printing characters in it at the start of what appears to be a blank line when viewed in a standard text editor. It's the line after "M109 S205 T0 ; heat to Cura Hotend". Possibly this was in your slicer start script?
PS - there are some more earlier in the file, the EF BB BF sequence. Neither of them is a valid UTF-8 character sequence.

Are you using the Cura plugin to upload the gcode file directly to the printer or are you uploading via the DWC?
What version of DWC are you using?

OK, Thanks! I believe that was it. It would only pop up once when starting but didn't affect the print.
Thanks everyone for the help!
Cheers.
