so, i'm finally getting to this tonight. unfortunately, the pnc3100
doesn't have the led indicators referred to in the manual in the files
there's just 2 leds, one on the control surface, the other on the
controller, both flash, the control surface one more slowly.
would any of the group members be interested in testing one of my
output files for a fee? (they are 3d scans of nude women, if that
makes a difference one way or the other).
that way i can tell for sure if this is a machine problem or a code issue.
