General Mach Discussion / Re: Newbie question about push buttons
« on: January 06, 2016, 04:50:56 PM »
FWIW (and probably not much...)

I was going to do a hardware interface, but it got too involved for me so I went the other way.  Bought an ELO touch screen and made my own Mach3 touch screen panel.  Now I can change it any way I like.

I do have a vistacnc hardware pendant for MPG.

Here is my screen.  Once I got started it turned out to be *very* easy to add new buttons.  I shamelessly stole buttons from other developers.

General Mach Discussion / Metric lead screw, but work in inches
« on: January 05, 2016, 12:24:11 AM »
My mill has metric lead screws, but everything I do is in US units (inches).   Any worry with me setting native units to inches, then entering a converted decimal amount under motor tuning "steps per".  Or should I be setting it to metric and just use US units G-code?

thanks

General Mach Discussion / Re: Limit Switch and EPO

Its a Milling Machine.  I guess I should have the limits trigger an ESTOP, which means the whole thing shuts down.

Mach3 under Vista / Re: Diagnostics Page Tutorial?
« on: December 30, 2015, 04:10:21 PM »
Not sure if a document exists or not.    I am guessing you are asking about the port pins, input & output signal indicators?


The "Port 1 Pins Current State" is literally the state of the parallel port pins.  These are the pins assigned in the config "ports and pins" section.

The "Input signals Current State" are the state of various Mach inputs.  If you are using the parallel port, this should match up with the satte of the parallel port pins  as assigned in the config "ports and pins" section.

The "output Signals Current State" are as the inputs, but for the Mach outputs.


Does any of this help?  Do you have a specific problem to use as an example?

General Mach Discussion / Limit Switch and EPO
« on: December 29, 2015, 06:20:33 PM »
Howdy all, I am just doing a new build and I have been thinking through my EPO circuit and limit switches. 

Should my limit switches (these are *not* home switches) cause an EPO condition (which means spindle shutdown, stepper power supply shutdown, etc.) or should it just be hooked to mach and have mach do a software stop.

General Mach Discussion / Re: limit swith vibration
« on: December 29, 2015, 06:14:33 PM »
Hi  Ed,  I had a similar issue but it was not vibration directly causing a switch to trigger - it was vibration setting up noise in the line that was picked up by Mach.  I adjusted the sensitivity in Mach.  I set debounce interval to 1000 and Index debounce to 4.  Solved it.  Maybe you have the same?

General Mach Discussion / Re: WINDOWS 7 AND MACH 3
« on: December 29, 2015, 06:07:18 PM »
I run with Windows 7 32 bit with no issue.  Using the built in parallel port works fine.  However the second parallel port (for pendant) was a real pain to get going, I essentially had to use a very old driver to make it work.

*sigh* nevermind.  I just found out that the VistaCNC pendant has a dual pole EPO switch with one side connected to terminals on its special parallel port specifically for shutting down the control box.

General Mach Discussion / EPO on pendant shutdown power to spindle/steppers
« on: December 29, 2015, 12:57:22 AM »
I have Mach3 parallel to a Bob Campbell BOB. I am using a Vista CNC pendant Parallel port to Mach.

The pendant connects directly to Mach through a second parallel port.  The pendant has an EPO button that puts Mach into reset mode.  I would like when I hit the pendant EPO that it puts mach into reset, but also will send a signal to the BOB to flip a relay and shutdown the power to the CNC spindle and steppers.  BUT I dont want a press of the Mach reset button to trigger a full shutdown.  I want Mach to treat the reset button and the EPO button on the pendant differently.

I am OK with with wiring and parallel port stuff,  I just cannot figure out how to config Mach so that when the eStop pin from the pendant goes high, to also send a signal to the BOB - but not to send a signal when I press reset on the Mach screen.

Suggestions?
