the difference was the constant stream of speed commands, but the
output stream is constant all of the time anyway, which shoots holes in
my guess. The VFD may have a noise filter on the analog input that makes
the difference.

was "DC braking", which injects DC to the motor for slow speed braking
and doesn't use the braking resistor. One can hear the motor sing as the
motor comes to a stop when this feature is active.

the gear edge is metal to air or air to metal. I tend to agree with Andy

sy to check, but I haven't gotten
round to it. One down side is that the transistors on my drives blow out
before the fuses and I have to replace them every time I test. The
traces have started to pull up so replacing transistors is a bit of a
project, and I don't see much point
f OpenSCAM. Much of this
depends on the availability of developer time and funding.
Here are some of the current ideas:
Real-time cutting simulation.
Rotational axis simulation.
5-axis simulation.
...
"
So it still might be a good starting point.

led until the
power has stabilized. Also, as a relay opens or closes, there might be
damaging voltage spikes. Plus, power input filers are usually a good
thing to add in front of PWM type drives and VFDs to help reduce
electrical noise but may also provide some protection.

four places. This was enough to cause problems. You
might check to see that the I and J values in the G2 and G3 commands
match the arc radii. Posting your g-code might help.

Does anyone have comments on this package?
