Boy that is a tough one for sure sounds like a internal communication problem maybe, I'd pull and reseat all the boards and see if that helps, as far as loading fusion programs make sure they are a...

Wow,l its been a while since this thread had much activity, we still have two BTC's don't use them as much as we did at one time but one or the other gets used at least once a week, they still seem...

Not sure about your mill for sure but usually they are powered on with the spindle motor

That machine has steppers, it looks like a almost new machine, very clean

I definately understand your love hate relationship with the TC, there is a lot of kinetic energy in the tool changing motion,especially with a carousel full of tools, on ours when the damper is not...

JohnnyTurn, we have a TC3g and one of the most important peices of a good working tool changer is that little damper, it actually works in the extended and retracted position. Ours wore out, all the...

I see no reason in the world it wouldn't work, the biggest obstacle would be the adapter you would need to build to drive the angle head. Maybe you could replace the R8 in a bridgeport one with a...

Since the carousel is stopping and loading what it thinks is the correct tool I have to bet its a problem with the prox switch loosing count, maybe the switch maybe the wiring , that’s where I’d...

Just a few thoughts, when the wrong tool is put into the spindle , on the monitor on the right side goes it say the tool that is actually in or the tool that should be there? More than one person has...

You guys did a great job on the restoration, the monitor upgrade is really cool, your installation report is a testament to how good and tough this old Bridgeport iron is. Jon P

Hey Kevin, yea not much activity here anymore, not many people using the BTC's, we still use our two but we have a Torqcut 3G that has taken the load off the BTC's but they keep going , the Y axis's...

We have a machine, Torq-cut with DX32 software, that had the DOM go bad, so we replaced it and the software and we are back in business, there seemed to be a few differences at first but after a few...

OK well after a little more investigation i think,( i have been wrong before) the longer pull studs like you have are for BT spindles and the shorter ones are for CAT spindles

nlh, are you sure you are using the right pull studs ? I've got a TC3G like forhire and I use the short pull studs like in his posts, i've often wondered if im using the right ones maybe our machines...

Very interesting Randy, u really got a good deal on the Renshaw, the reason I'm interested is because we do a part that has a existing hole witch is always in a little different place that we go down...

I'm pretty sure ours homes the tool changer and the Z axis at the same time first then the Y and the X last, I know I've gotten in a pickell and jogged off axis before I homed it to save my bacon, I...

So just a little checking this morning, on the Torq -cut the spindle has two encoders, one in the motor to keep track of speed and direction it goes to the spindle controller, the other belt driven...

I can't tell you how many times with the old BOSS machines I had the card extender out with scope and data logger hooked up following signals and 9 out of ten times it was bad connection, micro...

Is the mechanical connection between the encoder, spindle and motor firm ? no loose key ways, belts etc. My guess is it may be something simple that has been overlooked although I am not aware of how...

This is a wild guess but it appears the encoder is working and the motor is trying to orient it, is it that the brake isn't being applied at the proper time to hold it in position? Good Luck Jon P.

From my experience when you start blowing the fuse for the drive you have one or more scr's not working, I happen to have a Sencore scr tester so I'm not replacing all of them, usually only one or...

Those are the SCR's, I've replaced at least six or eight of them in our drive in the last ten years or so

Thanks for the reply Randy, yea vactra #2 is what it will be I'm sure the metering units are calibrated for it. I found a thread where a guy had taken apart his transmission to change bearings and...

Picked up a Torqcut 3G this fall seems to be working well, a few questions though, for way oil it calls for Vactra3 or equivalent , most of our newer machines with linear ways use thinner oil, what...

Here is the wiring diagram for the series II299610 good luck Jon P.

yea I saw your previous posts about the probe but it didn't sink in till I looked at it the second time, what I want it for is finding centers etc.so I guess I need to try it out. For the last 20 or...

I'm also looking for the digitizing software for a DX32 machine, Torqcut 3G, picked it up about a month ago previous owner hadn't used it in the last four years due to a few problems , seem to have...

Picked up a Torq-Cut 3G 1997 model year it is set up for 240 3 phase input power, we have that in our shop but we run most all our machines on 480V 3 phase power just wondering can the input be...

Oh one more thing to wake a few of you up, while looking for the schematic I ran across these pieces of literature , the BTC was $ 58,080.00 in this 1982 add !!!!!!!!
