hey john you were right on the money I did a google search and found some examples http://linuxcnc.org/docs/html/hal/hal-examples.html
this worked perfectly. I know have a toolchanger classic ladder program that can unclamp the spindle and also a working manual unclamp spindle release button I just have to say if I didn't watch sams E stop video and learn all about Halcmd -fk I would really struggle. halcmd makes everything so easy. I tried it in the hal file first and getting the names right is such a pain haha. halcmd auto completes them for you making me make less mistakes regards Andrew On Tue, Apr 21, 2020 at 3:42 PM John Dammeyer <[email protected]> wrote: > Sorry, I may have been premature.
