Seller ended up backing out on the deal so I ended up buying a 1979 Lagun and doing a retrofit on it. I would do what you can to keep the servos even if you end up with newer drives (which is pretty...

Could also have an external PLC. I know my 6MB powered '84 Okuma has a Mitsubishi PLC that handles toolchanges and machine error code displays.

Maybe a dumb question, but one Google didn't seem to have an answer for.

I've got an old Okuma & Howa MC-4VA VMC. Fanuc 6M-B. Bought a PTR-USB interface so I can load big programs off of a thumb...

Thats what I was starting to think but in MDI you can orient the spindle using an M19 command, tried that and still got this error. I'm starting to think that its an error for "something was...

1984 Okuma & Howa Millac MC-4VA, Fanuc 6M-B controls, Sequence doctor toolchanger running on a Mitsubishi PM-905C2 PLC the Okuma PN for it is Type SC-45 199-(blank space)

1) where you located

3) what control is on the machine

Errors 84 and 86 resolved. Soldered in a 3-AAA holder on the wires coming out of the mitsi PLC and put some fresh alkaline batteries in. Checked way lube pump and there was some way oil in the...

Bought an Okuma MC-4VA from eBay that I'm trying to fix up and get functional. Have gotten a few issues worked out now trying to get toolchanger figured out.

Realized today that the toolchanger...

Ok machine says its a 6MB series M51 V12

I was unable to find any sort of bypass button but jumped out the hard limit switch and was able to get it to come off the hard limit that way.

I've got an Okuma & Howa Millac 4VA I recently bought. Fanuc cabinet on right side of mill (from the front) has a tag that says "Fanuc LTD Type A02B-0060-B201 Serial 7107991 Date 1984-0" I don't...

Tag on cabinet says "Fanuc LTD Type A02B-0060-B201 Serial 7107991 Date 1984-0" If that isn't sufficient let me know where to find that information elsewhere.

How does one patch the base software...

Trying to learn myself about this old control, of course that naturally means screwing things up and trying to figure out how to undo the screw up.

Machine is a ~1984-85 Okuma Millac MC-4VA with a...

Need a 7i29 dual servo driver board to replace one that blew up on me last weekend. Mesa tells me they're out of stock for at least a week while some work gets done on their incomplete boards. I've...

I haven't seen it but I've got some Toyota love myself, I've got a '92 SR5 XCab that I've put a custom flatbed on and regularly use and abuse....260k young.

I'm in Ogden with a shop in Boone. Stupid forum seems to have reset my settings to say "USA" instead of my town again...

So I was looking at buying some Lapp USA Olflex 190CY 22 ga/10 conductor braided shield flexible cabling to use to connect the encoder line drivers on my mill to the Mesa 7i29's I just bought to...

Are these ferrous shavings or nonferrous shavings?

If ferrous, I recently bought a Slugger magnetic chip brush from Trick Tools ebay store. It cleans up a lot and fast from the chip tray in my...

I'm working on retrofitting an old Lagun FTV-3 knee mill. As far as I can tell it never had limit or homing switches on the spindle axis, and I'm curious to see how other people have mounted...

Depending on what "prep work" you are referring to you may consider a dedicated (and faster) machine for beveling/deburring depending again on what exactly you are doing:

HABERLE Tube Deburring...

if you need to cut aluminum somewhat cleanly and portably, I'd be looking at a Milwaukee or Dewalt portaband, although I shy from the battery powered versions you may have luck depending on what kind...

This is directed mostly at people who have done their own retrofit project, anyone with experience on Rutex drives your input is especially appreciated.

I'm working on my Lagun FTV-3 retrofit, I'm...

It would help if you guys edited your profiles or said what town you're in on this thread to help connect with others, thanks!

Hey guys, as jealous as I am of those of you who got a CNC to retrofit that came with a HUUUUGE nema cabinet, my Lagun did not :(

So after looking at the cost of shipping for a big nema cabinet...

I just called them and talked my problems over - I'm a lot more comfortable now than I was when I made the OP.

For anyone else who is wondering - if your motor measures out above the .03*(input...

Started up a build log. In Rust I Trust

KSI Labs, LLC

Price is a bit spendier than I had hoped, but I'm interested in it because it seems to be the least-expensive option I can find that can run on either Mach or EMC. Searching found...

I got a few R2010's used off ebay after initially expecting to use gecko drives on my mill, which I've set up a power supply for 75 VDC with a 1500VA Antek toroid, 4x 60A bridge rectifiers (2x per...

TTT - also curious if anybody else in the state is doing retrofits on old stuff? I'm getting further along on my Lagun retrofit. Been meaning to start a build log sometime.

You should edit your location to be a bit more specific than just united states.

I don't know about your locale (well, don't know and don't know where it is) but I'm pretty happy to have a couple...

Hi, can't speak with authority on the Ultron system but I have a few answers for your other questions. I have an FTV-3 I'm in the middle of retrofitting so I've struggled with some of the same...
