Well, I've mentioned it a few times, but I finally got it. Between work, weather, and a basement shop remodel it's taken me about 8 months to make this finally happen.

Part One is taking the mill apart and getting it loaded on my trailer:

Part Two is getting unload at home and into my basement-down steps! I am still re-assembling, will update soon.

Kenny,
Looks like your move was a success. Thanks for the pictures. What are the specs on the Steppers and what voltage is your power supply and what drive are you using?
Looks like a nice conversion.

Cool, hope it works as is. It sucks trying to figure out what the person who put it together. They never make schematics, I am guilty of that one as well!

Kenny - Looks like a successful move! Now time to start making stuff :D I did almost the exact same thing this spring. Bought a used BP, drug it home, off loaded, dis-assembled and lowered into my basement in chunks. What a saga that was. Currently in shop remodel mode to make a space with lighting and extend the 3-phase power to it. Mill is still all in pc's 6 months later for the same reasons you mentioned :mad: Winter project. I would post photos but I don't want to encroach your thread.

I know very little at this point...I know the steppers are rated at 500 oz/in and the main power supply is 25 amps at I think 24v but not 100% sure on that yet. Unsure on the drives, will get that info soon.

I know it works, because I have seen it in action! There are detailed schematics included, some are hand drawn and some are done on CAD. The guy who did it is an older friend of mine and he is very detailed luckily for me. He was using CamBam and Mach3 and I have the PC that he was using also, that is going to be the hardest thing for me since I have NO experience with them or any other CAD or CAM.

Good luck! I was lucky in that I was able to wait to move the mill till the shop was completed since I bought this from a friend that was not in a hurry to get rid of it.

Only 24v? Should be closer to 70.

I added some pictures to the Part2 album showing the BOB, stepper drives and power supply.
