I know this is an ancient thread but I have the same question and there do not seem to be any replies to the OP. Anyone out there know the answer? Burt

General Mach Discussion / Re: E-Stop: Latching or Momentary?

Just a retired hobby guy in Virginia. However, I understand your points. Presume that I would need to connect one or more relays to disconnect the 36VDC Power Supplies (X2) 115VAC inputs.  Reckon wiring the latching E-Stop switch N/C contacts in series with the relay coil. would do the job. No reliance on the PC that way. Have two latching style switches on order from China so I guess I will use the Momentary switches for something else. Thanks for the information. Take care.

Found some information about PoKeys, outside my price range right now but does look like a good way to gain inputs, etc. Thanks for the information as well. Take care.

Thank you for the response. Being a dinosaur I do not know what Pokeys are. Thought was to wire both the Momentary and Latching in series, using the NC contacts. Now I have to do more research. I like the idea of activation of the momentary on release rather than having to hold it down. Take care. Burt

General Mach Discussion / E-Stop: Latching or Momentary?

« on: May 01, 2015, 04:06:19 PM »

Hello all:

Absolutely new at this; am converting a G0484 Mill/Drill to CNC. Question that is bugging me now is: Does the E-Stop Switch have to be a Twist to Release, ie. Latching, or can it be a Momentary Pushbutton? Concern is that if Momentary does Mach3 reset the emergency stop function and go back to doing whatever it was doing before the OMG moment. Hope to hear from someone. Have searched for the answer but have not been able to find anything on this topic. Take care.
