- In this video, McKale and I update an outdated Bridgeport Boss 6 Series 1 CNC mill to work with newer components. We tear out the old guts, and update it with a simple PC, breakout board, stepper driver setup.
PC used: Dell Optiplex 755 SFF stripped from the case and mounted direct to the panel
Breakout Board Used: amzn.to/2NSz3RF
Stepper Drivers Used (set at 7.2A): amzn.to/2ZMgEs8
Power Supply Used for the Stepper Drivers: amzn.to/3byZgg7
VFD is a salvaged Automation Direct GS2-22P0

Hi. I really like this video. I'm doing the same conversion and would love to see more detail on this process. Keep up the good work.
Thanks, will do! I will be working on some more videos with more information on this build.
Awesome stuff!
I did a diy uplift to a boss series1 from bare metal about 8 years back. I used linuxCNC, I think bigger steppers (1200oz/inch with dm860a's), and originally I used a similar breakout board, but found on very rapid moves I was loosing sync when all axes were moving, so I retrofitted with mesa 7i76 fpga based control hardware in place of the crappy BOB. I swapped the variable drive for a vfd but kept the switchable backgear in the cut down head for low speed torque and programmed linuxcnc to read switches and use a gearbox calculation for speed & direction. I wish I had of fabbed up a real disc brake on the spindle though. I've span the stock motor to 2500rpm testing the vfd overdrive limits, but its scary and I wouldn't want to be in the same room as it running at that speed with the risk of the armature bursting etc, so I limit to 1800. For a psu I used that honking big transformer and built a ac->dc converter with stud rectifier and huge caps. I have all the super stable DC I'll ever need out of it to run 5 axis and ancillaries in comparison to a generic switchmode supply. Since retrofitting, I've gone on to 5 axis with a diy built trunnion table, integrated probe hardware, a self contained high speed spindle alongside the main one, encoder on the top of the spindle for rigid tapping and a few other tweaks. Its been ok but limitations, the qc30 is a pain, if you run cheap chinese qc30 toolholders the flange tolerance is often out and it causes the tooling to loosen in the spindle and fall out and it means you have to babysit programs as you cant retrofit a ATC, and the lack of enclosure can get intense with chips flying off at cnc rates, so I made a plexi bed enclosure that moves. But... A few years back I got a Cinicinati Arrow 750 vmc, and the bridgeport sits in the corner unused because of these issues. If I was going to do a bridgeport again, I'd find one with a spindle that's iso30 and ATC'able, build a enclosure for it to avoid flying debris, and add a stepper right onto the knee and have a summing Z set up to give more usable Z range mid program.
No vids, I posted a thread on hsm but I quit there years ago so the above will have to do.
Loved this! You really upscaled your production value with the B-roll & music! Can’t wait to see the racing rig video whenever that one is done. 🏎💨👍
Thanks man! It's a lot easier when you can film someone else! Haha.
Thanks for the video and info. I know someone that wants to give me one so I'm doing some research to see what I'm getting myself into before I decide to pick it up.
No problem! If someone is going to give it to you, it sounds like a no brainer! Snatch that thing up!
Great restoration! I did something very much along the same lines but I kept the orig steppers and stepper controllers. I'm using Intel Atom D540 mother board to run LinuxCNC and love it!
Awesome! I am glad these old machines are still getting used today!
We retrofitted a Bridgeport Series II a few years ago. We put Mach4 instead of Mach3 on it. It’s a great machine for what we are using it for.
I also have the series 2. Bought it for $200.
I haven't done full cnc yet. I just did the driver's with three MPG wheels.
excellent video, very informative.
Glad it was helpful!
Great video
Thank you!
Love it! I have a boss 7 too, have a few videos of it on my channel.
Really enjoyed your video, both the content and quality. Can you share any additional information about the mill itself, like model or version. I am going to try and find one to upgrade.
I used to run one of these with the OG tape reader and controller. What a pain...
MUCH respect to you, Sir!
putting together one of these now. Went with DMM 1.3KW AC servos (longer .625 shaft with 5mm keys; requires broaching pulleys and fabrication of NEMA 42 spacers) and a centroid control board. These are huge machines, had to pull the entire spindle assembly off to get it in my garage and broke a few straps hauling it on a trailer home. I also needed to spend about 1k on line filters, line reactors, relays, breakers and din rail buses. spent around 4.5k on upgrades, 1k for the machine and a few hundred in rentals to move it. I didn't bother with using the old steppers as it appears that they can not micro step meaning they have a max resolution of .001" (.200" lead ball screws with 1.8° steps) meaning they will have serious issues with surface finish and they are under powered for modern CNC tool pathing (can't move this heavy table with acceptable G's). If you decide to go with AC servo's keep the coils in the power cabinet; I didn't bother checking mine (for power ratings and inductance) before I scraped them but you may be able to use them as load reactors saving anywhere from 250 to 500 dollars. Mine was covered inside and out with a mixture of fine chips, dried coolant and broken down way oil. It took me days to just get the cabinets clean and I am still scrubbing crud off of the column/ram. I've gone through a few gallons of purple power already lol.
Great video, i'd definitely like to see a more detailed video on the board. Also, I'm curious how much the new system cost?
i am working on one just like this ,,any information and more detail in the build would be great ,, and maybe a detailed list of the items used to retro fit
Yes, I am definately interested in a detailed video. I purchaed a very similar machine and was starting the process of tearing it down when I came across your video. I'd like to use the original motors as you did. There are 6 wires and I'm only familiar with 4 wire motors. Any help would be appreciated. Thanks!
Nice job, Very much appreciated the video.. I'm preparing to retro a boss 2 series bridge port with the old steppers. Can you tell me how to buy the right power supplies for the steppers?
I would really like it if you did the detailed wiring video
I'm trying to retrofit a similar mill. I have too many holes in my information. Could you show how the x y z motors are connected. Voltage to drive. I think I need to get a power supply. I have a vfd, 3 drivers, and a breakout board. Hopefully my old computer still works.
Great video. I just got my hands on a series 2 interact 4 and planning the same/similar conversation. Both the breakout board and the motor drivers are currently out of stock. Can you recommend suitable alternatives?
Thanks
Thank you! If I am not mistaken, the Series 2 Interact 4 is a newer machine, and possibly equipped with servos. Servos will need a driver that is compatible with them, not the ones I used on mine. My older machine uses steppers. As for breakout boards, just about any cheap breakout board will work.
Hi.What is the pitch of the ballscrews?
Good Video, I am converting the same unit. I am looking to add a brake resistor to the VFD (using ABB) Do you have a suggestion on which one would work best?
Thank you! I plan to add one, but have not gotten around to researching into it just yet. When I do, I will make sure to include it in a video!
donde puedo descargar el software intercon y cencomm para bridgeport cnc 1?
Sick music
Thank you!
Starting the same project here. Had one for a few months sitting in the shop. Where did guys get all the stuff?
We used a generic $25 breakout board (sainsmart), because we wanted to make sure everything worked on the machine before spending more. The drivers are stepperonline DM860T and they are wide open at 7.2A. We are driving them with a Mean well 1000w 48v power supply. The VFD was recovered from some scrap machinery.
Great video. Im doing a BP Interact 4 currently. What software and breakout board are you running? Im definitely looking forward to a more indepth video on wiring and hardware/software used
Hello Race, how is your bridgeport interact retrofit coming along? I am most likely picking up the same vmc and was told it runs but I think a retrofit will be in order. Let me know I'm interested if you think the interact is worth the investment.

Hello Turtle, where's the follow-up video I need it like right now! I like this video seems straightforward but the devil is in the details!

How did you wire up those old boss motors? Did you run them as unipolar as originally designed or change it to a bipolar setup. Also does the driver limit the current somehow?
I ran them as from the factory. I have the drivers maxed out at 7.2 amps.
@@turtlelaboratories Thanks.
@@turtlelaboratories I am curious if they will stall out since I believe the factory voltage and current were higher.
@@crissd8283 They do not stall from the testing we have done, unless you run them under 10 IPM. Under 10IPM, they make quite a bit of noise. We are working on tweaking the settings to make it better at super slow speeds.
i have a litte question why do you use 4 stepp motor driver if you have 3 axis??
im doing the same project
nice video!!!!!
Good eye! It's so I can add a rotary table down the road!
I would like to see the indepth video
Yes, what’s going on here? Is the VFD driving the spindle and all 3 axis?
I’m thinking the VFD is running the spindle and they added some mini servo drives. Auto lubrication!!!
Please make another video showing how all the axes are driven. Also how are you collecting motor feedback?
i have the same...mine was already converted...has touch screen, jog shuttle wheel...running mach3
Sounds like a great machine! How do you like it?
@@turtlelaboratories its great...had it 8 years now...i have made allsorts with it...trikes...bikes...other machines...has usb so i just load up a G-code and hit start
What retro fit products did you use in this video and Approximate cost. I need to do the same conversation...Thanks for your attention
Hi, and thank you for watching! I have the parts listed in the description!
Your video very well, and although it is true you have changed the electronics, which is the engine, you have tried to remove it for maintenance. I have a similar milling machine, but to get the motor out, I think you have to disassemble almost everything. or not???
Fortunately, I have not had to remove any motors for maintenance yet, so I cannot speak to that. I wish you well with your project!
How did address wear in the axis and droop in the knee?
Mine has pretty much zero backlash due to not really being used in its previous life, so I did not do anything to address it.
Would you share its post processor
What controller did you go with?
Check the description for the breakout board we used. Thank you so much for watching!
@@turtlelaboratories what software though?
@@Sad-lawlessness We used Mach 3 in this video.
@@turtlelabs idk how I missed that, my bad!
The wiring diagram, please.
Hey guys, would you guys be for hire? I have the same Bridgeport, I bought a Mach motion CNC set up for it a while back, 13 years ago actually, and I never got it going. I’m looking for someone to get my machine up and running. In my shop I already got the three phase converter wired up using a local electrical company, now I need the rest of it but together. I don’t know how much it’s worth to have someone come out and do that, I’m in Topeka Kansas, but I’d be willing to pay for it for sure. Let me know!
Ryan, we really appreciate the offer, but we don't really do that kind of work for others. If you have any questions about your build, hit me up at theturtlelab@gmail.com. I would be more than happy to assist, if I can.
@@turtlelaboratories I'm
do not replace line reactor
why not a masso g3 controller
I prefer to use a PC as a controller, and the cost cannot be beat!
doesn't support a lot of higher end CNC options and is expensive for what you get. I went with centroid and spent about 800$ for a controller, wireless MPG pendant, and software. Masso looks nice (love their touch screen) but they don't support ridged tapping or advanced probing and you can't really dig in and tinker with it at a lower level to meet specific requirements. Masso is better suited for hobby level machining; these machines works best as toolroom CNC mills or a budget CNC mill for a fledgling machine shop.
You got a centroid controller for less than $800? Who did you talk to? I have this exact machine and need to retrofit ir
