Hi Lloyd,
I have no idea if you will get this email, but I though I would give
it a try. *I just purchased a bridgeport r2e4 boss 9 mill, and moved
it into my garage workshop. *I plan to convert it over to mach3, emc2
or centroid control, but in the meantime it would be nice to see if it
actually works. *Rather than buy/build a RPC, it would be nice to just
convert the control over to single phase 230. *can you elaborate on
how you changed your machine over to single phase?
Best Regards,

FINALLY, I got my r2e4 Bridgeport converted to single-phase.
No more of that damned RPC singing over in the corner, no.
As it turns out, the R2E4 machine is basically a single-phase machine,
anyway, except for the spindle motor (which is definitely 3-phase).
The electronics all run off two (single) phases of the incoming power,
and there are no references to the phases. All it took to get them
converted was to move a couple of leads.
To adapt the spindle, I installed a VFD and a relay isolator that would
track the F/R signals from the motor relays, and signal the VFD to
start/stop/forward/reverse.
It cost only $149 and some labor.
Now to make metal in the QUIET! G
