Trying to figure out what is giving the Bad Command error

Dragon

I keep getting a Bad Command error when I start a print sliced in Cura, I don't get the same when I slice with Prusa.
Here is the first part of my G-code, hopefully someone can point out the problem

Thanks!

Does it mention what the bad command is?

That should be G92

You should remove those commands from the Cura start gcode. They will override your config.g settings.

Also make sure you have cura set to reprap flavor gcode.

Dragon

No, that's the problem just comes up as bad command.
I will look over what you posted, I had to remove the G92 to stop it pulling all the filament out after print and it is set for RepRap.

Cheers.

You'll need to set Cura to use relative extrusion.

Dragon

It is
Still had to run a script to make sure it did.

Cheers.

Is it though?

Phaedrux

If you go to the actual gcode console view does it tell you more about what bad command it is?

Dragon

It's no longer backing the filament out after every print, but I am still trying to tune it have not started printing with it since installing the Duet WiFi.

Cheers.

Dragon

No still just says bad command.

That is the script entering the code but not changing the text.

open the file in an editor that shows you whitespace and non-printable characters?

Dragon

I just tried that in Notepad++ but not sure if I got it right, that is the code copied from Notepad++ pasted at the start of the thread.

Thanks and Cheers.

The wiki for M204 in RRF does not have an "R" parameter. https://duet3d.dozuki.com/Wiki/Gcode#Section_M204_Set_printing_and_travel_accelerations

Dragon

Thanks, I have already taken those 4 lines out but still get the error.

Cheers.

i thought it printed the line that had the bad command, maybe just to usb?

anyways, i see a line with just whitespace below M109, so thats what made me think it may print the problem, its just not something we can see?

Dragon

I will try removing that Thanks!

Cheers.

Dragon

Ugh, that didn't get rid of it. LOL

What firmware version are you using? Most firmware versions usually report what the bad command was.

Phaedrux

Can you post your homeall.g as well? Perhaps your bad command is in there.
