RE: [CAD_CAM_EDM_DRO] Re: Bridgeport Series 1 conversion and othe r stuff

Hi Joe,

Unfortunately mine won't come with any tooling (but maybe I can beg a
little). The spindle is NMBT-30 which I see is still available in the MSC
catalog. I had even thought of changing the spindle to an R-8 to match my
other mill but I think I'll leave the NMBT-30 for the quick-change ability.
Maybe I'll build a tool changer some day ;-)

Where can I find out about CNCPro?

I knew about the 12 x 18" .vs. 9 x 42" issue but I'm sure all my work will
fit in the 12 x 18 except for odds and ends which I can do on the 9 x 42.

Do you think I can get by for awhile with the AHHA 6 amp driver if I have
lower speed and cutting force requirements? In the future, which do you
think would be cheaper - replacing the motors W/6 amp motors or purchasing
new drivers?

I'll be watching to see how yours comes out ...

Regards,

Chuck Hackett

I am in the middle of a Series 1 conversion right now. I gave 2000
for mine (with 25 holders)
The steppers OEM holding current from the service manual is 8 amps
(for the sigma motors)
I already had Anaheim unipolar drivers (7 amp) so that's what I am
using for now. CNCPro as the controller.
I personally feel that these Series 1's are the best thing going for
CNC conversion, but be aware that the table travel is only 12 x 18".
don't let that 42 inch table fool you.
The guys I bought mine from were sort of friends. I hooked up two
axis and the spindle motor and spent one Saturday morning cutting with
the thing before I commited to buy.
I should be fully up and running after christmas and I will post
specs and pics.
I think a grand for a series 1 cnc is a pretty good deal. By the
time you go buy motors, belts, pulleys, mounting hardware, limit
switches, ballscrews, etc etc.. You could't touch all that for a
thousand bucks. Plus the series 1 with the rigid ram is a very sturdy
machine.
Try to get them to throw in some tool holders.
Good luck
