General Mach Discussion / Plasma torch settings via spindle....

« on: January 28, 2014, 02:28:18 PM »

Could someone let me know which settings need to be set in mach to enable me to control my plasma torch via the spindle relay on my BOB?

I'm generating g-code in sheet-cam but am not at the stage where I can test anything yet as I'm still building the table.


Thanks

General Mach Discussion / E-STop & Limits Wiring...

« on: January 17, 2014, 06:57:13 AM »

Hi all, first question, a bit basic

I am building a CNC plasma table and as I have never used CNC before, its a learning curve.

Reading the forums and the manual, I have gained some insight into the wiring methods to use for limits etc, but want to check I have the facts right...

There are only 5 inputs available (1 LPT port),
I can daisy-chain the limit switches (2x, 2y, 1z) and only use 1 input,
The E-Stop is on its own input, or can it be daisy-chained in with the limits?

If I later add THC, I believe it will need 3 inputs (Up, Down, Arc OK)?

In Mach3 I can use the limits as soft-home switches too (with the caveat of making sure the carriage is off the limits before homing)

With the E-stop in the limit chain, this setup will now use all 5 inputs, am I on the right track??


Many thanks

Dave
