General Mach Discussion / what file to copy so mach3 on desk pc has same config as the one on my mill

« on: February 11, 2016, 08:50:28 PM »

for simulation of running parts on my mill during the evening when working on gcode, etc I'd like the copy of mach 3 that I installed without the parallel port driver in my house to have the same configuration of that attached to my mill.  Is there a file I should copy from the shop machine to replace a file on the house pc that would accomplish this, or is there any point to that? BTW I'm a new user....

thanks

General Mach Discussion / Can all 3 of my homing switches share one pin in Mach 3?

« on: February 02, 2016, 04:32:15 PM »

I'm revisiting a partially completed Boss 5 Bridgeport conversion that I had to set aside for a few years, it uses Mach3 & the Ashburn BOB:

 http://ashburn.home.icx.net/index.html

I've never set up one of these conversions and have close to zero experience with Mach3, but have watched the videos and read most of the manual...

All of the limit switches are set up and run (I think) all in series with the OEM Estop button and use the one pin 10 active low to stop the machine.  I want to add homing capability and have added home switches to do so.   Can I wire the 3 axis home switches all in series?  That is, will Mach 3 know which switch is triggered in turn as it homes each axis because it is homing that particular axis? (assuming it can be set to reverse off of the switch so that the pin is no longer active after each axis completes its home/jog off home move)  I read 4.6.6 & 5.6 of the manual that says I won't be able to <ref all home> but because Mach3 homes each axis separately shouldn't <ref all home> still work?

I prefer not to use the existing limit switches as dual purpose home switches at the moment.  I have only one input left on the BOB...

Any advice would be greatly appreciated.
thanks
