Complete breakdown on what I spent on the DM2800 CNC retrofit. I've got an entire playlist for this project: kzread.info/dash/bejne/c5NrrNdrdrXbibw.html

Thank you for documenting your build well Pete and as importantly, sharing the true costs of the conversion. Helps other to go into similar projects with eyes wide open.

Thanks Marty! Hopefully folks find it to be a helpful resource. On a personal note, It feels great to see this project to an end after so many years of being on the back burner.

Amazing project sir.

Great movie, explains everything. Compare this to my retrofit costs. Machine DM2800 (operational and complete) $ 2000 A set of Mitsubishi servomotors 700 $ CS-MIO control + small electronics 500 $ Servo for spindle $ 200 Another $ 300 Together, it costs $ 3700, I have original stepper motors and electronics for sale. Either way, this retrofit makes sense when comparing the DM2800 to today's small machines.

Thanks! It really is amazing how many options there are out there today for doing a CNC conversion. I remember when I did my first around 1995, there weren't many choices for the home hobbyist.

Thank you so much for your feedback, regards from Mexico

Thank you too!

Well Pete, good work man and thanks for sharing! I've watched all through the episodes - tip of the hat to you my friend! Now I will be very interested to find out - two years on - how you have used and liked this machine. All best wishes for you! Subscribed today.

perfect video!

Glad you liked it!

Pete. Informative videos. Thanks for posting them. I do have a question. When you were setting up your DMM what diagrams and settings did you use? I am working on mine and having a bit of a challenge with it.

I used a diagram that DMM supplied but had to add a bit of interpretation to because (as I recall) the diagram was expecting solid state outputs and the acorn has relays. Still the same basic idea just had to pay attention to hooking to the correct contact (normally open or closed) and what the common wire needs to be.

Pete, I just finished watching your series on your CNC retrofit. My project is a Bridgeport CNC retrofit that I have had for 3 or 4 years now. I have had some difficulty staying motivated on that. I just feel overwhelmed sometimes with all I need to learn. Anyway I really enjoyed your videos and learned quite a bit. I do have a couple questions I hope you can answer. I don't recall you adjusting the gibs for the ways in any of your videos (perhaps I missed it). I am wodering how you adjusted those and what that entails. Also, what PC (brand/model) did you use for that project? It looks like a nice small computer that would fit in my cabinet and wanted to check them out. What are the considerations when buying a PC for the project? Thanks again. It is a great series.

The gibs on the 2800 are full length and there is a screw at both ends of the dovetails. You loosen one and tighten the other to move the gib. I usually start by overtightening them a bit and then backing off until I don't have any motor stalling issues. It always seems to take running back and forth a few times to get them to settle into their spot. It is not as easy as it would be on a manual machine where you can feel what you are doing by turning the hand crank but you can start to hear the motors complain a bit if you go too far. I used a Shuttle computer. My primary decision there was convenience. We use them for machine control at my day job and had them sitting on the shelf. It was easy to have them just deduct it from my paycheck. So I didn't really analyze it too much. If I had tried the shuttle and it didn't work, then I would have gotten into the specs but as it was, it just worked. Thanks for watching!

Next i hope you get a maho !!!!
