Out of the blue --> Home X doesn't work

sbNielsen

Hi there,

As the title suggests, my Duet 6HC suddenly gives me this error message when i try to home x - or home all.

The X axis runs fine otherwise, i can move the print head and print just fine.

When I run the 'Home X' it jogs 2 small moves to the in X+ direction, but nothing else.

Here is the error i get from the console:

G28 X
Error: Bad command: homex.g
Error: Bad command: called to home the X axis
Error: Bad command: generated by RepRapFir
Error: Bad command: mware Confi
Error: Bad command: guration Tool v3.3.16 on Sat Jul 01 2023 14:29:49
Error: Bad command: G
Error: Bad command: MT+0200 (CEST)

Any fixes for this?
Would also love to know what happened.

Best,
Søren

@sbNielsen Check the homex.g file in your sys directory. It sounds like the comment character ";" has somehow been removed from some of the lines in that file. Post the contents of the file here for folks to check.

Nothing changed on the homex.g file.
Looks like this:

homex.g
called to home the X axis

@sbNielsen You're missing semicolons in front of some of the comment lines it should look like this...

;homex.g
;called to home the X axis

Note the ";" in front of some of the lines.

If your homey.g and homez.g files are not generating errors, compare them against your homex.g file and check those comment lines.
