Have lathe and steel... these are the fun projects for me !
well, this isnt the boss .. its a V2E3 i picked up a little while back.. the outfit i purchased it from stripped the controls and converted it back to a manual machine... anyway its on the burner to be converted back to CNC after the boss. I dropped by the dealer i purchased the mill from on some other business and was able to pick up the back and side cabinets.. so i spent a couple hours stripping the old electronicals out... anyone need any parts LMK as ill be listing all the old stuff on ebay.. I have all the boards, transformers, drivers, etc
Some of the new gear is showing up.. bought the mesa 7I77 board and picked up a couple DMM servos so hopefully i can start working on this stuff once i have all four cabs gutted.. ill haul off the 2 larger side cabs to the scrapper and just keep the smaller back cabinets... maybe ill get lucky and find something even smaller in the meantime.
Basically no difference between them all the mechanical part are the same, just a different name and some electrical and control differences, it's all in the numbers stamped on the top of the knee, the telling part is also the timing pulley ratio for the axes drives
Good find to get the electrical cabinet that will give you plenty of room to up grade it

I did the motor swap to nema 40's had to make shaft adapters. Built a 70v power supply and using gecko G201x drives. My Boss 5 has 2 to 1 reduction on the lead screws. I kept the travel dials they help in calibrating mach3. Has the Kwik Switch 200 spindle tooling can be hard to get at reasonable prices. Them beasts are one stout machines.

Made some serious progress on removing the old controls from the Bridgeport. i was going to strip out the cabinet and save the transformers and other electronicals, but, i feel like it will take me another half day to complete. So, off to the scrapper they go ! Now to decide if i will move the rear cabinet to the side. It will be easier to access the electronics but i will have to cut the cabinet and reweld the lower mounting bracket. I wont be able to do any serious work till next saturday so i have a week to decide..
Was told it was a boss 5 when I bought it. I made no changes to it other that replace the motors and controls. has a serial number stamped on the ways of "CNC 4208" will this tell us more about it?

Its newer than mine.. i have 1804 and 1 to 1 pulleys hey Machine Jack.. how bout some pics !!!
Hay I'm at the age that I am lucky to be able to answer the telephone the first button push. I think I have an old Kodak laying around somewhere. I do have a small camera but posting the pictures may be a challenge. Will see what turns up. What cam system will you be using? I was using an old Mastercam X4 that the boss donated to me when they upgraded when I was still drawing a pay check. Recently my engineer son fixed me up with a seat from where he works and I now sport MC 2017 now that is a big relearning curve. I tried Auto Cad Fusion but found it to complicated so I'm sticking with MC. Trying to grasp solid modeling as I want to be able to machine patterns for my metal casting interest.

guys, its been awhile but im getting back on track with this project... its taken a couple of turns however, current config is centroid acorn and DMM 1.3Kw servos... just waiting for the backboard for the electronics to be cut... i tossed the original cabinets in favor for a later model cabinet ( single cabinet to hang off the side of the machine )
would love to get some input on motor speed control... keep the original pneumatic s ? switch out to vfd ? anyone with ideas on spindle speed tach ?
here is my latest video on the build.. showing the electronics and servo selection

not the first time i saw that photo.. ( beautiful i may add )
Mactec, Todd, i ended up purchasing nema 42 servos with the correct mounting pattern and shaft size .. this will be a " direct fit " replacement. I just needed to get the project moving.. i previously purchased nema 34's for this machine so i will save them for the next build... at least i can use the boss to cut the adapters !!
