Kirk,
Yes, I have used the dampers and they work well. My motors at home don't
have the dual shafts. I made due with some old motors. Things are working
well for me right now without them. I could run faster if I had them on
the motors.
Here are work, I have seen the results and it's not
Please, I did not in any way mean to be unfair to EMC. I did not mean it
in that way at all.
EMC is a fantastic program.
What I mean is that by doing the electronic gearing there is no way to
avoid a condition where a stepper motor is operating at a step rate where
resonance is present. It

Hi Ben,
Remember, Synergy does things differently. It writes code that is
offset by cutter radius and also uses G41/G42.
This means the tool table diameters need to be zero. Small deviations
are then entered into the tool table to
compensate for sharpening or small adjustments in

So far, I have used Synergy to draw the part, then draw the tool paths
and use the path way points to write G-code. That method may not be
usable for complex parts, but I suppose it lets you use tool
compensation. I have only written a few programs, so writing programs by
hand is probably good,

Fanuc makes machine controls, not machine tools.

Gene,
I may have to investigate adding dampers like you have done. I didn't
consider adding it between the motor and the machine. I had always seen
dampers on the back side of the steppers.

Does Synergy's post allow you to specify the end point of the arc

and the center of the radius AND the distance between the ending point

Hi Stuart,
I have to play dumb here. I just let Synergy do it's thing. I didn't
find anything in the post.
If you draw it correctly it seems synergy will do it.
I think emc is double precision internally. Plenty of resolution. :-)
Someone will correct me if this is incorrect. ;-)
