Well, she's up and running! And making accurate parts, to boot!

Minor issue. When I jog the machine in incremental from the panel, it jogs .0001, ,001, and .010. When I use the MPG it jogs .0004, .004, and .040.

I'm not finding anything in a search. Is there a setting somewhere to adjust that? Many thanks and happy holidays to all!

Mark

My huge thanks to everyone who helped me with this project. Your expertise, knowledge, and especially your patience can not be repaid adequately.

Make sure the parameters are set correctly for the MPG (Wired or wireless?)

Finally! Good to hear.

As Marty said, sounds like a parameter is not set correctly. You are getting 4 counts when you should be getting one, and we have no idea what MPG you are using.

Bingo!

Parameter 350 was set to 100, changed it to 400. All fixed! Thank you Marty!

Mark

Edited: Just now saw your reply Polar. My MPG is the one supplied by Centroid. Thank you, too!

Now that this is up and running, I'd like to start considering options to bring a 1997 Bridgeport Romi lathe back to life.

Before I started this adventure, I posed most of my initial questions to sales instead of here. While they were tremendously helpful, I learned that I should have started here. What would be the best forum (AllInOne, Oak, or Acorn) to start a new thread down that rabbit hole? The machine may have axis servo drive and spindle motor drive issues.

Many thanks,

Mark

Mark, it depends. What kind of axis motors will you use? I would imagine that machine has DC brush servos?
How about overall picture of the machine, and detailed pictures of the control cabinet. Knowing what you've got and are working with might get some better suggestions from what route we might go if it were ours.

Thanks Marty!

I found these on my computer. Do they help at all or do you need more detail?

I'll gather up those pictures! I do believe that it has DC brush servos.

Mark
Seeing pictures of the condition of the machine would help. Likely SEM DC brush servos, if they are in good condition then All in One DC would be my first choice.

Does it have a turret or just a tool post?
No turret, then new AC Servos and Acorn a possibility.
Your budget might dictate your choices.

Four position tool post. Might think about a turret in the future.

Budget, as always, is tight, but not impossible. All in One would thrill me as I actually feel like I have a grip on how that works now. But not averse to using another recommendation.

Mark

Edited: It's actually in pretty good condition. The pictures do not do it justice. The iron is excellent. It seems to be covered in gooey oil residue which will clean up.
