Bridgeport Manual to CNC conversion...

I just like having things covered as far as practically possible - in this case if the e-stop is pressed, the CSMIO is told to stop as well as power being removed from all servo's and VFD's, both via separate channels. I think that should be ok, the XPS contacts are forced apart so pretty much guaranteed to open.

BTW, what happens if a servo encoder fails - does the motor runaway or stop??

On an AC/Brushless motor, the drive should detect a fault.
With a brushed DC motor, potentially run it into the limits at great speed.

Got the panel finished, bench-tested, all passed 100% :)

Got the pendant rough-wired so i could bench-test the panel, seems functional.

All axes homed and jogged perfectly, no surprises, e-stop system seems to work ok.

Managed to lug the panel into the cabinet, nearly ruptured myself but it's in now and bolted down.

Tomorrow will be final wiring on the switches and limits etc, plus re-rigging the pendant for the next power-up test. Then I'll probably strip the pendant and send it out for powder-coating, or just spray it if impatience takes over ;)

Nice job Dave

Got the panel wired to the machine today, most of the big jobs done now, its running again, ready for testing.





Small jobs to do like secure some of the cables when i work out where they need to be, make the belt covers, cover the Z axis drive, fit the light, then figure out how to run her ;)
