If you do setp parport.1.pin-16-out True from the Show Hal Screen does that work?

Yes, this works. Makes it happen on the show screen and the watch screen

And the file name is M100 with no extension?

Correct. M100 with no extension

And what happens when you type M100 in the MDI tab?

Nothing happens at all. Got an error the first couple of times, until I moved the two files into the correct directory.

Otherwise it looks right to me.

John I'll try that in a moment. I've written a short Gcode program to try the M100 and M101, but can't get it to run at all. Much head scratching going on here. Tom

BigJohnT OFFLINE Administrator Posts: 4964 Thank you received: 88 Karma: 134	I've just noticed that I had to shut down EMC after fixing the M100 file or I kept getting the same error. Might not reload it or something every time. John

TarHeelTom OFFLINE Expert Boarder Posts: 99 Karma: 2	Just tried adding the "eval" statement, but that didn't seem to help. Just reconfirmed, doing it from the hal-show page still works, and actually makes the led on the bob go on and off.

Switching 'bash' for 'sh' doesn't seem to help.

Looks, at least in the hal window, that 0 & 1 can be substituted for false & true without any ill effects.

Wrote a short gcode program involving a z movement, an x movement, turn on vacuum, return x to 0, then return z to 0, turn off vacuum.

The program runs, but hangs up on the M code every time, unless I comment out the Mcodes. So the M code files appear to be the problem.

Any other ideas?
