TNC530 ISV simulate M140
(OP)
Hi All,
I have a post with vnc for a Heidenhain TNC 530 which doesn't simulate the M140 MB command (move back along tool axis). Does anyone know how to add this into the vnc controller. I have done a bit on the post side but nothing with the vnc.
Thanks in Advance

Try using user defined events. To take out the M140.
I am not so trained on ISV.

I wanted to ask you before, but here it goes.
An UDE is not necessary at all here, I assume you already have M140 in your postprocessed output
The easiest solution, but not the right way, is to define some intervals e.g. from A to B move to position 1, from C to D move to 2 an so...
The proper solution involves some basic maths (not rotation-translation matrices as in cycle 19), just move the tool from where you are in its real axis direction in simulation, until you get intersection with one of the 3 plane's equation: one that defines Z limit, other Y and finally X, each intersection defines a vector, the shortest one will be the target point
that should give you some ideas
