I was aware that the spindle was replaceable/rebuildable, it was more me just wanting to move forward as far as new tooling purchases. My next machine will at least be a BT30 machine. So, it made...

I was curious about this as my spindle was starting to sound a little noisy. Also, I wanted to get a more standard set of tools that I could use in the future and BT30 fit that criteria. But, I...

I copied a part of a quote from another thread "Dynas had Dyna's SKIP control. Spindle amplifiers came in a couple different versions during those years. They switched to the Mitsubishi controls...

So, I bolted back together the few things I took off, moved the lathe close a socket, plugged it in....fans came on and nothing else. No startup, no manual spindle control, no lights. The control did...

I don't have the PC card or the software. I am certainly willing to try it out. Do you or anyone you know have the control card or copy of the software. I know I can feed the machine over a serial...

The guy I bought it from said he was using it and it worked perfectly. I decided to redo everything as soon as I got ahold of it and have never powered it up.

I wish it was an H. More Pics coming soon.

By the way I have been reading your build and MRM RCModels build over and over again for ideas. The is another guy over at Dyna mechtronics DM3000 lathe...

I wanted to start a thread for my lathe update. I am fairly new to machining and this is my first lathe. I have been a member for years, but never had the time to dedicate to my home shop. With that...

If anyone has one for sale please let me know. I have posted on the yahoo group, but it seems that place is now a ghost town. I have wanted one for a while, just never had the funds.

I was at a custom jeweler's this week. The machine they were using was this one http://www.gemvision.com/html/products/revo/revo.html. They also also make a software package which they used that is a...

Guys, just tell where to buy what he's looking for. Centroid makes a nice looking retrofit for J-heads using a Z axis setup from Elrod Machine. Here is be....

Okay, I am retrofitting a Bridgeport Series I CNC. I am going to be running a
Galil DMC-1860 which in turn will be controlling 3 or maybe 4 (haven't decided yet) Compumotor Gemini GV-6U12e servo...

I love it when a community comes together! Thanks for all the insight.

Thanks that really helps. So I am guessing from that the bolt patterns are the same. Does anyone know for sure?

So you are saying "yes" these will bolt right onto a BP Series I CNC mill with no mounting plate needed? Just unbolt the old and bolt on the new?

I am not talking about power. I was asking about the actual mounting plate sizes on the housings matching/bolting to the mounts on the mill.

Does an adapter plate need to be made for a BP Series1 Boss5 if I want to mount modern servos or is there a "bolt-on" option? I have read about needing a 5/8" shaft and that a Nema 42 is probably...

I agree wholeheartedly. I just want to make sure I am not sending money into the void.

Has anyone heard of these. I know they are chinese but they look good and are really affordable.

I thought about using them on my Bridgeport Boss...

Sorry Cams, I really have no idea when it comes transistors. I think in terms of cars. Too big of an injector, too hot of a spark.

I understood it was bigger. I guess I should have...

Being higher current rating, power and voltage is a good thing right? So would this an acceptable part or is it out of spec? I compared the MJ16012 to the MJ16020 both from Motorola and the 20 looks...

posted question in the middle of thread instead of being at the end where it would be seen as the newest comment

I am more than willing to admit that I am grossly misunderstanding the documents I have glanced through. I just never saw the words "closed loop" listed in them. It is possible the whole document...

After reading Galil's application notes yes it's possible to run almost anyone's drive and motors. But from glancing through the application notes you can run in either torque or velocity modes, but...

I answered my own question thanks. The answer is yes and no.

i think I am leaning towards Galil motion control for the simple fact that I like Camsoft's features. Does anyone know if this interconnect module will allow me to run other companies servo drives?...

Can you mix different brand controllers, drives/amps and servos? Such as Galil motion control, with Parker servo drives and Allen-Bradley servos? These were just random choices (X+Y+Z)

It seems...

Will do

Just for clarification, the schematics are in the maintenance manual right? I am about to have a Boss 5 (my first mill ever!) sitting in my shop in about a week and a half with a bad transistor or...
