It was very hard to get a Bridgeport Series 1 CNC maintenance manual with all the right part numbers and all the adjustments, assy and dissassy., if anyone needs this manual please send me a message and I will send you a copy of it

CNCPic6.jpeg Generally easier and better to wire the panel out of the cabinet and for bench testing. Easier to correct issues. I fully agree with you but all the wiring is still attached from the AHA system and the motors are still on the machine and it's very easy to jumper all the systems from th...

Received the transformer, it's very nice like Marty said.

Waiting for the 70 VDC transformer to test the new system.

The BOSS 5 machines went from a 1:1 belt reduction to the ballscrew, to a 2:1 reduction sometime during that BOSS 5 run. I recommend 2:1 if you don't have it already. As for the hardware, check your ballscrews for wear. I had mine re-balled. It needs to be done before the wear is too great. Also, t...

Did you take pictures as to how the original steppers were wired at the stepper motor and the old control? Remember, I suggested you find the specs to the original steppers to be able to calculate and size the replacement power supply.....or search to see what others were using. Remember to benchte...

So far I have torn out the whole Bridgeport electrical cabinet except the incoming fused 3 way(240Single phase) on/of switch. Re-Mounted the Acorn board because the whole system is starting to take shape(at least in my mind). According to martyscncgarage, I purchased a new transformer from Antekinc....

Marty. I just re checked the power from the AHA transformer going to the AHA driver boards and its 50VDC, does Acorn do DC for the motors or do I have to change to the Oak CNC Controller, or the ALL in 1 controller? I believe that if one does any conversion one needs customer support!! The only maj...

BRIDGEPORT Series 1 CNC Conversion Acorn Board, Gecko Drivers INFORMATION, keeping original Nema 42 Motors Will post information as I am learning and doing it. Thanx to martyscncgarage for pointing me in the right direction. I have been doing machining since learning lathe and CNC mill in high schoo...

Yes, for an infrequently used machine (you might find you use it more when you get used to the control and learn to use INTERCON, Conversational programming) I think Acorn and keeping the existing steppers should be OK. You say you did CONFIRM the power supply voltage to the existing AHA! drivers? ...
