HURCO KMB-1 Control Update

Apologies for Clumsy writing on my part,
I understand the issue and thanks for the clarification Tommy.

My thought of testing the system with an Orient command, I understand now was very naïve.
From others examples, introducing this ability requires pretty much a total tear up of the whole spindle control setup, and a need to get into the ladder world not just a reroute of the enable signal, and that's a move way too far way from any comfort zone for me.
Ducking this piece of implementation brings me much relief.

Thanks for your effort to help.

Andy, just found your orient.svg  which has encouraged me to have another go. Especially as I realise the function could be useful when probing.
Thanks for your clarification.

I've been distracted by configuring a CAM post for this machine, and kind of blown away, that after months of learning, I can decide on a strategy, select tools speeds feed etc, and output the NC code from the CAM system and linuxcnc, parses it without comment. Not only that the machine runs the code and the the part is to drawing. Just excellent.

The orient.svg chart, while I get some of what it is telling me, i cannot understand how I need to convert it into hal statements. I thought by now I would get this stuff but I don't. which ones are loadrt, addf, setp and net ?

Sorry to be a dunce.

Could I ask for some pointers please?
