Call external subroutine not working in recent versions of LCNC

Pretty sure I supplied those files before .. and remember.. what you "simulated" did not seem to address the issue.. but I thank you for your effort. I have put up my ini file, and the hal files for you to look at. I don't know what is going on, I suspect rights issues... I can load those files via midi all day long, UNTIL I load up another file, then I lose it. So, the main question I will pose again, should I push this as a defect, and if so, what documentation should I upload? Very big thanks...

Right now, I am getting around all this by loading the toolchange program manually for each tool I need. PIB..

Does the "metal touchoff" work properly?
One difference I do see is that there is a classicladder interlock on the toolchange3 button, that seems to be checking mode.is-mdi

What happens if you switch to the MDI tab, _don't_ run an MDI command and then press the button?

Well, the metal touchoff .. was working in the prior release.. yes. ( 0 added for offset.. ) So when I did wood, the .625 was added. When I did metal, nothing was added to touch zero.

So.. the number 1 issue as reflected in my original post is:

1: From boot, I can go tot he Midi panel and execute the o<xxx> call tool change without problem.
2: The button doesn't seem to work till i do that .
3: But, once I load a GCODE file into the system, the midi command won't find the toolchange file anymore and the button no longer functions.

Can you do a quick test? Open a Halmeter and look at halui.mdi-command-00 and make sure that it does go "true" when you press the button in the scenario where you are seeing a problem?

Booting up and getting ready... will send you results

Booting up and getting ready... will send you results

1: Homed unit
2: Pressed First button ... halui.mdi-command-00 == false
