General Mach Discussion / Re: USB or LPT2 MPG Pendant with E-stop?
« on: October 08, 2014, 06:34:47 PM »
I am not sure how the C32 handles the E-Stop but it will likely be hardware I would think.
So your thoughts on USB versus the CNC4PC pendant is correct.
I would personally never consider having an E-Stop via USB, even if it were a secondary E-Stop as the tendency to rely on it could be dangerous.
If the C32 only sends a signal to Mach and relies on Mach to do the E-Stop, then that is not good either but as said I do not know how the C32 handles an E-Stop. If it is hardware ( blocks step/dir outputs independent of MACH) as well as sending a signal to Mach then that is the preferred way.
Just my opinion of course
