I am looking for the motor side variable speed sheaves for a Bridgeport BOSS 6 CNC. As far as I can tell, all the Bridgeport CNC knee mill vari-speed sheaves were the same. I have put a new bushing...

I know that interface screen. I had the same software on a Discovery 308-Sx bed mill (incidentally, it was a piece of cr*p machine, but that's a story for another forum).
It is quirky, and not in a...

I have used version 6.2.1 since we upgraded from an earlier version. I still use it on a daily basis. I think I know all of its strengths, weaknesses, nuances and foibles. I have learnned a lot of...

I don't know about the torque 22 head, but I do know this about the Discovery 308-SX:
(not in any particular order, not even by level of annoyance).
1. The control uses a very, very obsolete LPM...

I have the set-up, programming, and maintenance manuals. I will copy, punch, collate and put them in binders for $100. E-mail me at [email protected]

Be very careful to make sure that the wild leg from the 3-phase is NOT wired to your CNC Control circuitry, only the motor. Make sure that the two 120 volt lines from your single phase 220 are...

You need to read the Bridgeport manual for a description of the editing commands, to be able to manipulate programs in the machine, enter them, etc.
You can use Bridgeport's EZ-Utls program, a...

A thought about using a phase converter: A very wise machine repair tecnician who used to work for a Bridgeport dealer in our area told me that it is Absolutely critical to NEVER connect the wild leg...

I have been using ECG 53 transistors for years. They cost about $9-10 each and hold up well due to a higher amperage rating. I understand that ECG is now part of Philips and they may be hard to get,...

We have a pneumatic tool changer for our Bridgeport Boss9 machine (retrofitted). The driver is kaput. The main part of the unit is a Chicago Pneumatic CP-720 wrench, modified. I have tried to rebuild...

Bridgeport EZ-CAM is very user friendly. I have used it for about 25 years. You can find several versions of it available, I like Version 6. They spun off into a separate company after Bridgeport...

This is not a for sale ad. I have no stake in this machine and I am not selling it. I saw a posting on the Binghamton, NY, Craigslist for a Bridgeport Boss CNC - looks to be about a Boss5, but I'm...

When Mastercam's post processor outputs your Bridgeport code, the first number after a drill code is the full depth, the second number is the depth of the FIRST peck, and the third number is the...

A quick rule of thumb I learned at Bridgeport programming school in 1981. In a milling cycle you are telling the machine "How Deep?", hence a minus number. In a drilling cycle, you are telling the...

I have a B'port 308-SX that was purchased new in 19xx. Since we bought it, we have replaced the Vector Drive, the coolant pump (Surprise! It's 460 volts, not 230, nearly burned out the replacement),...

Four words of advice: DON'T FRACKIN' DO IT!
1. If you do, the lender will push you to go to the highest possible amount that they imagine you might be able to pay, if a miracle occurs. (But they...

I have a MachineMaster controller card that I purchased exactly 9 years ago today. It is in a Bridgeport Boss 5 and is working quite well. The controller card came with Slo-Motion Controls software,...

I have been using EZ-CAM since it only came as a $6000 package with a NEC 386-16 computer with a monster 2 meg add-in expansion ram card. (Actually it added to the 640k to make up a total of 2 meg.)...

I would like to know a few facts about the EMCO Compact 5 CNC Lathe, which is a desktop, "teaching" lathe commonly found in tech schools, etc.
First is how powerful is the spindle motor? What is the...

Sounds interesting. Give me a shout sometime and maybe we can find a time to get together. My phone # is 607-687-0143 for my shop and home. I'm usually around all day, and most evenings, so I...

Well, yes, I agree that most people with $30 K and decent credit would buy a mill and a lathe and set up a shop in their garage or their basement, while holding down a full time job until they found...

Several years ago, I did just that. Put the whole shebang up for sale through a very reputable nationally known business "broker" the only thing that got "broker" was me, to the tune of 5 grand. Not...

It IS a small world. I'm not that far from Anderson Hill Road. To answer your questions: I have equipment that is up to 30 years old, including the CNC mills, which is paid for, and still running,...

I live in Owego, a town of about 5000, often confused with Oswego, also Otego, Otsego, Owasco, etc. Durned English settlers didn't do a very good job of deciphering Native American names for places,...

But, seriously, folks. I'm still here and still lonely. Despite the recession, the collapse of the banks, the cutbacks in just about everything, it appears there's a continuing market for my...

The Boss9 came in two basic flavors. Look closely at your machine. If the servos are Contraves, with BEI encoders, your best bet is to ditch them along with the electronics, as the whole works are...

The best that the Boss 3, 4, and 5 machines could do was .001 steps, after the pulley/belt reduction. The boss 6 finally progressed to .0005 steps, but that wouldn't be good enough for what you seem...

You can buy a complete flood coolant system from Manhatten Supply or McMaster-Carr, but will cost about $300 and take up quite a bit of space. Also, the tank holds 10 gallons of coolant or more and...

Klem,
I don't know about the tnc 145 controller, but my B5, and B6 machines are notorious for developing all sorts of weird problems when the boards get dirty. If you haven't checked them recently,...

If you're just looking for older version(s) of EZ-Cam software, do a search for it online, as I think there are several hacked versions floating around that are free or very cheap. I still use my...
