General Mach Discussion / Re: Where are work offsets saved?
« on: March 23, 2006, 06:32:30 PM »
when using offsets its good practice to use g54,g55....ect for all of the coordinates Ie. x,y,and Z ect.. that way if you machine is biggenough to set multiple offsets you can just use the next coordinat system.

Of course on the other hand you could just leave g54 zero and then the next coord will have a different number. The only problem arrising from this is if you break or reset a tool you have to make sure to always use g54 as the pick-up. otherwise you have a difference that could crash the machine.

These are not big issues until you start running a tool changer.

General Mach Discussion / Re: Rutex SPI
« on: March 23, 2006, 02:27:07 PM »
Adding the ability of SPI communications to mach2 might or might not be that hard, But it would ad a certain amount of flexability in the software. There are already options for +_10v to step/dir and i believe to PWM but to spi. nothing.

It shouldn't actually be that hard to program an app to take the step and direction impulses from mach to SPI. But this would be less disirable just because you are still limited to the frequence capability of the computer.

Has Art responded to any inquirys about adding SPI?
