Re: Semi-good high speed spindle idea?

Jarret,

I myself don't know about Mach* . I'm using Cncpro, because
of the sheer simplicity of it. I just change the feedrate in
the gcode to slow or speed things along. I imagine Mach probably
can do this as it does everything else. Most of these routers
have whats called "soft-start" meaning they won't work with most
external speed controllers. I'm sure there are combinations to
work around that too.
