Re: [CAD_CAM_EDM_DRO] mach3 question_2

All that info should be loaded when you run the Mach3 Loader and select
the new XML file.

As far as inches/mm goes, that depends entirely on your leadscrew. The
Taig is 20 turns/in for example, which works out nicely, but if we were
to state it in mm, it would be an irrational number. I don't know Sieg
myself, but Google'd this: looks like the Sieg comes with a metric
leadscrew- whole-number ratio of turns/mm- but some people converted it
to a turns/in leadscrew. If it's metric, you'd... I guess you'd have it
in Metric mode when you define the leadscrew, then you should be ok to
change Mach3 to inch mode if you want to define the max feedrates,
acceleration, and so on. It's gonna go into Inch mode when it runs a
file which declares units to be inches anyways.
