Beginner question - Mach Input
« on: October 19, 2011, 09:18:58 PM »
I have installed the demo version of Mach3 on a PC and I have a breakout board connected to the printer port.  I want to connect an E-Stop switch as my next step.  In section 4.14 of the Mach3 Software Installation and Configuration Manual there is a sample schematic.  On the upper right hand of that schematic there is a line "To E-Stop Input".  My question is where do I connect that line on the breakout board?  Do I use one of the breakout board inputs, pins 10-13 and 15?  

Attached is a picture of my breakout board.  Thanks to Chuck Hoelzen.

Stephen.

Yes, just choose an input thats not presently being used then set that up as the E-Stop in Ports and Pins, Inputs.

Stephen,

Connect the EStop wires, one to GND and the other to any spare input pin (pin 10 would be good). Then configure Mach / Ports and Pins / Input signals / EStop to Port #1, Pin 10.

It works.  I get an external Estop signal.  Yeah!

I only used the portion shown in yellow (on the attached) for experiment/trial purposes.

Hi Stephen,

You are going to be an expert in no time  ;)

Glad you got it sorted.

I have no experience with connecting hardware to a PC so this is a good start.  Next I'll do some limit switches. 

I noticed my Diagnostics screen has more information than what is shown in the manual (Mach3Mill_1.84_UserGuide.pdf) Appendix 1, Screenshot pullout.  I have something like Port 1 pin status LED indicators.  Has there been a revision to the system that didn't get included in the manual?

Mach is constantly evolving and trying to keep the manual up to date would be a very expensive thing to do, expensive in time for Brian as well as money, so afraid it is what it is.

I was wondering if there is any information on the Port 1 Pins current State area?  Why 24 Led's?  I would expect 25.  And why is the 4th LED lit when I have my E-Stop input tied to pin 15 on the breakout board?

Thanks for the replies and help.
