Did you write your own driver to do this?
As far as I know the current EMC2 HAL drivers do not support a
USB-connected 7i43.

Question on the system mechanics. How accurate do you need to be with a
Spray system? Why spend the money for servos in this application? I would
think the accuracy levels needed for spraying would be well served (cost and
operationally) by a stepper system?

The USB port is simply not supported by the HAL driver, so can't be
used with EMC2, even if it was a good idea.

Hi everyone,
We are planing a spray system on a X-Y-table and want to control it with
EMC. We want to use servo motors. When I see it right a common setup is
to use for instance a Mesa 5i20 board and a 7i30 H-bridge. My question
is now: what cable lengths are possible. I guess the H-bridge should
18 matches
