Mach3 and G-Rex / G100 digital inputs - how can I use them?
« on: July 07, 2007, 12:28:52 PM »
I want to be able to use the various G100 digital inputs to control the G100 digital outputs through Mach3/G100 software.
I am using Digital input 1 for the e-stop, but need to use other digital inputs to monitor the state of external hardware, e.g. enclosure open or closed, or various other safety control switches, and then operate or inhibit other parts of the system.
As an example, if the enclosure is open, inhibit the G-code from running.
Is there a way of using the Mach3 software to switch on or off selected digital outputs, depending on the state of 2 or more digital inputs?

Mach3 and G-Rex / Ref all home doesn't work?
« on: July 07, 2007, 12:20:42 PM »
My set up is G100/G203V hardware, Mach3 v2.00.081 and G100 plugin v 2.00.076 for a 3-axis CNC.
The limit switch also acts as the home switch (NC micro switch)
In the diagnostics screen I can home each axis in turn, consistently.
If I use the 'Ref All Home' button on any screen, Z homes OK first, then Y, but this runs into the limit switch and does not back off. Mach3 crashes (and G100?).
I have to shut down Mach3, switch off the controller and manually move the Y-axis on the CNC.
This has consistently happened with various versions of Mach3 and the G100 plugin.
What am I missing or doing wrong? Any solutions would be greatly appreciated!
Thanks.
Peter
