hi every one! im new here and new to cnc, i have been taking apart electronics since i was a kid!lol i Just got a Bridgeport Series 1 CNC Mill to retro, and need some help to do it right. i have a breakout board already its over kill i think but thats ok here it is 5 Axis CNC Stepper Motor Driver Controller Board TB6560 now i like what motorworks did to his BP and i think thats what i want to do am going to use the BP steppers i was wanting to know what you think i need to look out for and i was hoping motorworks my find it in his heart to take some new pics of his BP Power Box and tall me how to wire up the transformer? thanks ahead of time for all your help and look forward to talking to all of you,
thanks!!!!!!!!!!!!!!!!!!

I have a Boss 5 that I converted.
I removed everything except the steppers and limit switches.
I have herd some using on of the origional transformers for the DC power supply. Cant remember which one now.
I found a big toroid out of a batt charger I think. I rewound the secondary to give 70v once rectifyed.
Are you planning on using Mach3?

hi Stephen. ya im planning on using Mach3, ya i herd of ones using the original transformers to but don't know how they did the wiring. im glad to hear of so many doing this! do you have any pics of what you did? that you can post or email? i would like to see them maybe it will give me some ideas. so do you know are the steppers 70v? and 8amps?

if theirs any info on the BP i can get to let any one know more of what i have just let me know and i will get it for you

I don't think that stepper drive board is high enough voltage/current to run the steppers.

it is only 3.5a at 36v.

ya i thought i would have to make a stepper drive board or buy one

i was wondering about that is that board that i got a driver and a breakout board? or do i even know what im talking about? lol i was thinking i find some transistors and make a board for the driver side. but as i said im new to this lol

Those boards are junk, set fire to it now to save it doing it later.

You need three of these.

second one down.

A 50 v AC transformer that once rectified and smoothed gives you 70v DC about 500 to 600 Va rating.

A decent breakout board.

This one can also control the spindle if you drive it via a VFD

The driver you got is not going to do it.

I like the boards from PMDX.com. Good quality. Check out CNCZone. You are not the first to retrofit using the original steppers and you can see there what others have done.

so i can't use the Stepper Motor Driver KL-8078 on my breakout board because its half breakout board and half stepper driver? and win you say "Those boards are junk, set fire" to them lol you mean the BP boards? or the breakout boards that i got off of ebay or both? lol you never know lol

i was planing on getting Stepper Motor Driver that works with the BP steppers and use it with my breakout board. and i was going to do VFD


Inside my steppers it says P/n 026744 this is alternate motor for o25805
026750
don't know if that helps from what i have seen they are not all the same?

What John means is your driver board is garbage and so is the breakout. You get what you pay for.

The breakout might be OK. Dont know. Looks like a pretty generic buffered board.

Dont know about the motors, well other than they are pretty much junk compared to modern steppers.
