MDI Commands not getting read

I'm,getting this error


when I load LinuxCNC. Everything looks OK. Here's my .INI file.


and here's the section of vc-p2s.hal that causes the error. (Any of the four lines will cause the error.)


I've been installing a new VistaCNC P2-S pendant to replace my XHC HB04. Oddly, the same MDI commands all worked with the XHC. I've looked in Halshow, and I don't see any pins associated with the mdi-commands. So I think that the problem is in LinuxCNC, not the pendant or pendant configuration.

Any ideas?

PS, I like the VistaCNC pendant much better than the XHC. It's better built, and much better integrated. No unused buttons, like the XHC. Except for having to comment out the mdi command lines, it all works.

Try to delete the "empty" lines.

[HALUI]

MDI_COMMAND=G0 X0 Y0 Z0
MDI_COMMAND=G0 Y0

acc.:
net zero-x vc-p2s.zero-x => halui.mdi-command-00
net zero-y vc-p2s.zero-y => halui.mdi-command-01
net zero-z vc-p2s.zero-z => halui.mdi-command-02
net go-to-zero vc-p2s.go-to-zero => halui.mdi-command-03

Thanks! I didn't do quite what you suggested, but it gave me an idea. I replaced

with

and everything works!

There must have been some slight change to the newest version of LinuxCNC that caused this.

I actually found that I was having another problem that complicated diagnosing this one.

Under [HAL], you can have multiple HALFILE = commands, but ONLY ONE POSTGUI_HALFILE = command. If you have more than one, only the first one will be read, and no error message will be generated that the additional files are not read.

It took me far longer that I'd like to admit to figure this out.
