Re: I'm curious

The whole point of Mach2/3 is to work with any servo/stepper drive,
and work well. Almost all modern servo drives accept step/direction
input. The only disadvantage to step/direction is there in no
feedback to the computer. So actual position isn't known. This is a
minor problem, and with a good servo drive the actual position won't
deviate much at all from the command position. I haven't checked it
out, but don't Compumotor drives need a specific serial command set to
operate? When step/direction works with everything since it is
standardized. So basically if Art decided to program for just
Compumotors, then the price of used compumotor stuff would go through
the roof. It's also usually a big pain to get industrial servo drives
working properly. Some manufacturers even make you purchase the setup
software. I can't see step/direction going anywhere for a long long
time. It works for almost any application and doesn't need a special
setup. Rutex does have some new serial command drives, but I haven't
heard if anyone will support that standard....
