If you were to upgrade motors, I would go hybrid closed loop at the very least. I think your motors are NEMA 42. Measure the flange and mounting bolt pattern. Marty I was honestly guessing nema 34 by measurements I read without measuring the motors. The bolt pattern is 87-88mm. Edit. Just checked a...

I have. Was that you that emailed it to me? I actually looked at some replacement nema 34 steppers and was shocked to see a motor /driver pair for 100$. That's great too.

Acorn on its way. Can't wait to make some noises and chips !!

Hello all, I've been lurking about trying to figure my best option for my machine, I did a little messing about trying to get the original 1991 CNC4 operational with no luck so I'm going to go ahead with the original plan of converting it to acorn control. It's a Bridgeport series 1 with varidrive h...

My brother is setting me up with a newer touch screen laptop and a specific usb to db25 cable for cnc machines. Plus a usb hookup floppy to give that a shot. If my cencomm disc is good it should run on a pc right? https://www.amazon.com/dp/B077TVBF54/ref=cm_sw_r_u_apa_glt_fabc_PPWXPQTHP4CPD8MJVRBD?_...

There were a few discs that the owner and my friend both tried yesterday when we looked at it. When we were leaving and loading it up I found a drawer full of discs in the computer stand. I hook...

Congratulations on your new machine. Glad you got it home safely. Most guys drop the knee all the way and swing the head down when they transport them as it lowers the center of gravity for safer moving. I thought the same thing about the knee but the guy I got it from and my friend who came with m...

Well it's all mine now . Going to see what Centroid can tell me about the system.

So it's a CNC4 machine. I'm going to look at (and most likely buy it) Sunday. Im going to see about getting it going on original stuff but reality is that it will be sooooo much more user friendly on acorn and modern software. Being that I know very little about cnc programing at this point I'm abou...

I have very high mechanical skills including fabrication and welding, suspension design, amature machining on a small lathe. I'm an equipment mechanic at a museum. I worked in a manufacturing plant with full machine shop /tool and die room. I picked up as much as I could. One of the machinist there ...
