servo amp at 165 V (pretty hot) using the ppmc board set. The SEM had
a 2.5" dia by 2.5" piece of bar stock as a
flywheel. Accel was set at 400 in/sec/sec (slightly above 1 G).
Ah! Yes. Stopped to think and forgot to start again.
Been there, done that.

Hi Chris,
This could be a good place to start a religious war. On the other
hand I think some of the choices are fairly obvious, or will be until
someone points out a glaring omission. ;-)
I'm kinda with Ray in that I don't see a necessity to use up a whole

Hi Stuart,
Take a look at the spindle speed, gear change for the Mazak
conversion done at fest.

Thanks Jon,
Sometimes rants are needed.
As obvious as it would seem that spindle should be modal RS-274NGC is
not too helpful.
It does say that M codes (grp 7) M3, M4, M5 are a modal group but
somehow that got overlooked in the
restart scan implementation. Nothing is said about S being modal as
Hi Stuart,
OUCH! Those sound like a larger version of the Fijitsu-Fanuc amps I
pulled off the Mazak.
Rather slow by todays standards and not PWM so more heat.
If that is really 33 amps average and not peak then those are big amps.
I used Servo Dynamics 1525's on the Mazak but then they only have

For synergy users: (FYI)
Gcode output from synergy defaults to a tool path at the tool radius
offset and then expects the tool table
to contain minor corrections from this. This scheme doesn't play well
with emc.
However it is possible to generate zero offset paths in synergy; the

Hi Gene,
Two fluters work well for slotting or anyplace you have trouble
getting rid of the chips.
The harder the Al the easier it makes good chips. 6061-T6, 7050-
T651, 7075-T651 are good choices.
Recutting of chips that don't get out of the way generates lots of
heat and more mess as well a

Hi,
It would indeed be a nice feature if one could use a script to
sequentially run a series of g-code files. :-)

Hi Doug,
I've had passable luck on ebay for ball screws. Sometime you look and
there is nothing and other times several good ones. Just depends.
Good hunting.

Hi all,
Just to confuse the issue: has anyone done electrolytic polishingd/
deburring.
It should work fine with diluted sulfuric acid for steel of stainless

Not that that is bad if you don't want a bright surface. Just

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. ;-)

Hi Patrice,
You can use the link below to get to the page index for the emc wiki.
Peruse the Mazak entries for an idea of how a conversion goes

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 dimensioning.
