Hi
Studying these machine i have see that the version with mechanical button for reverse/forward spindle use a system called sensing for human hand touch detection
If you touch the button the spindle slow down automatically so you can operate the direction change without overloading the button/relay/card.
The controler is managed by a potentiometer 0/6v, i plan to use a 7i76e for the retrofit.
What did you think about allowing these spindle for reverse/forward with relay ?
It is interesting to add the sensing circuit ?
Any idea how use the sensing with 7i76e ?
First picture my card with missing component, second picture other one card with all stuff + wire soldered on the button case, third picture schematics

Ps : i does not like to replace the controler this one work like a charm with a lot of torque at low rpm and have direct feedback from encoder. (and mostly because i have a very bad experience replacing my Cortini lathe spindle contoler but i know is possible with some kbmg)
