I wanted to contribute my experience replacing the seals on an MP11 probe to this thread.

I bought a lovely old MP11 a few years ago. Seals had turned to dust. Oil and seal bits everywhere. I...

Hello folks. Apologize to dig up an old thread but I wondered if anyone had integrated G9 support into the DX32 post now. I have a TC22 and have noticed the very stuttery moves during adaptive...

The machine still seems to do this periodically. It doesn't seem to impact surface finish. The Y axis also shudders a bit. I wonder if the P gains are just tuned too high? I have been working on a...

EDIT: I realized that I originally was seeing .002" vibration, and now I'm seeing .0002"! So in fact this seems to have dramatically reduced or even fixed the problem. There is still some rumble, but...

After digging around I realized the motor was at high impedance and the driver seemed fine. Cable to motor ohmed out fine. Pulled the motor. Noticed that when I jiggled the motor leads the resistance...

I did some testing. The machine is able to move smoothly at 100 and 200IPM. The "jerking" seems to be it slowing down significantly for the "turn around" at the end of the adaptive clearing passes....

At least temporarily I gave up on trying to troubleshoot this more. The machine works fine, the Z just rumbles a bit. I haven't noticed any adverse effects when milling. Surface finishes seem fine.
...

After not finding any indication of problems with the machine I did some research, talked to my coolant vendor, and bought a refractometer.

I read in a few places that using form taps that don't...

This is old at this point, but you don't need to "drip feed" on this machine over a serial port. You can "drip feed" a program of any size from the machines own PC. You can run in two modes. For...

As noted in this thread, I did a long test tap (10"). S-Axis POSERR was stable around 2 on the way down, and -2 one the way up. I think this is in degrees. This would be a vertical error of .0004",...

Started machining up a nice fixture plate for my TC22. It is 24x12, with about 350 1/2-13 holes. I purchased a 1/2-13 form tap (OSG, steam oxide), and did a half dozen tests to dial in the proper...

Been some months and I've poked around at this but still not made any progress on it. The vibration remains. Otherwise machine runs great. Only manifests as slight surface finish issue.

Things...

I put an oscilloscope on the power input to the drive cards. Quite a lot of noise on there, which appears to be around 60Hz. This seems to be hinting that I need to replace the big input filter cap....

I had a chance to poke around with this a bit more. I removed the Z axis drive and inspected, checked the filter caps. They all tested correctly. I don't have a good way to test the big filter cap...

Thanks for all the advice Bart.

I haven't changed any of the tuning parameters but I have only owned this machine for about a year and it had a long life with its original owner before that. SW...

I made a program to move the Z axis up and down and listened next to the Parvex motor. No odd noises. No odd noises coming from the thrust bearing either. When stationary the belt is vibrating. I can...

Hm. If they were really made in Germany it is pretty suspect why they would be available for cheap in China, but it isn't impossible. A lot of machine tools get manufactured there, and they may get...

Hm. I will examine it a bit more closely. If I lift on the head casting with an indicator on the screw will I see bearing play? Head weighs a ton no surprise this bearing would go out!

I poked...

Ah ok. I see it in the diagram. Is there any good way to check the thrust bearing without disassembly? Is the PN the same as the X/Y thrust bearings? Oddly enough the diagram doesn't seem to have the...

Q1: I don't know a lot about the VMC600, but I have a TC22 which I believe is similar in many ways. There is likely a separate pressure regulator for the spindle air purge which you can adjust. You...

I bought a well loved TC22 last year and have been working my way through it. Beyond just scrubbing I went through the pneumatic, lube, electrics and fixed quite a few seals, leaks etc. Replaced...

I'm happy to grab the number off mine. I presume yours has been fitted with the larger Z axis drive already suited for the Parvex motor? You'll know since the Z axis drive will be a bit different...

I ended up finding a used Renishaw MP11 on ebay with the correct cable for my Bridgeport. Still had the invoice from Bridgeport in the box! It was very old and the seals were completely disintegrated...

The DX32 control has some parameters for the probe behavior. "Post Hit Continuation" and "Back Off Distance" which you might need to tune for your probe. I haven't fooled with these yet since I...

Appreciate the pics and videos! I just bought one of these machines myself. Your "internal views" are super helpful! Amazing work on the machine it will likely be the nicest TC22 in existence once...

Just picked up a "new to me" Bridgeport TC22. I want to get a 3d probe for hole center finding, edge finding and some simple 2d scanning. I don't need extreme precision, but I'd like enough to...

Thank you I am a dope. For some reason I thought that was just a preview of the file. Got it and responded to your pm. Thanks!

I am a new TC22 owner and the probing/digitizing feature is one of the things I'm pretty excited about. Was savoring this thread. Is a bit old but was hoping one of the contributors here might still...

I ended up parting it out. The SFM and CRT assembly are up on ebay now. If interested you'll find them (only ones on ebay!).

My plan is to make an aluminum panel to replace the control panel which...

I am nearing completion on my linuxcnc conversion on my R2E4. I am debating whether to sell off the complete control panel box (with the keyboard, monitor etc) or just sell of the bits inside and use...
