was at my Brothers 60th, passing it around all the gray hairs :laugh:
said something about my career, wound up meeting a tube builder, champ n kit form dynaco(sp?), Next guy, um you think....
spent some time isolating a problem on one of these
https://www.ebay.com/itm/MILLTRONICS-VM-16-CNC-Vertical-Machining-Center-Mill-COOLANT-THRU-CHIP-CONVEYOR-/143266484600
If anyone has had their fingers in these I'm interested in tips :laugh:
hoping to pick up at least routine maintenance, it was just great having one with folks you had one with 45yrs ago :icon_biggrin:
-
They came with a variety of controls over the years - I think... proprietary, fanuc, siemans if I remember correctly. Never heard a bad thing. They are kind of in the Haas range of capability. They are chip makers but not as capable as a high end mills like Mori or even a Mazak. A lot of off the shelf parts but some control boards are specific to Milltronics. Factory support is legendary. I would call them.

I did, and they were great, talked geek for a few minutes on what I found/did, n ya, happens to be a proprietary part, but have to send back the whole brain!
I did ask if there was anything I needed before I pulled the CPU, nope. This morning I had to put it back, relearn DOS commands :think1:
kinda fun getting back to system work. It's off to the pdf's :BangHead:
-
chips are flying :icon_biggrin:
I got the problem close, but don't have the cool kid toys for the system so passed it off to the pro's. 1 Zdrive and 20 parameters tweaked later, joy!
looks like I will land the maintenance contract in the spring, fun with oil, grease n sharp sheet :think1:
working on an R&D project over the winter. Shop needs a stand alone automated multi angle light duty (aluminum n plastic) drill (1/16" - 3/16") so the big gear can be freed up.
so got out the modern day outrageously priced erector set so I can work up a controller n software.
maybe I can re-use the proto-type to solder :icon_biggrin:

updated arm
tested 1st joint, needs the worm gear, added, working on 2nd joint :icon_biggrin:
-
2nd joint working, still need some small tweaks on 1st joint, adding a cheap on-hand servo for joint 3, then it's wiring n software
-
Ok, this project is starting to look like the robot arm Wollowitz built on the Big Bang Theory.... Are you SURE this is for the shop? :think1:

:l2:
one of my straight-laced exec. type friends asked what I was up too last week, told him about the arm, when he asked why, gave him my cheezy smile n told him my own was getting tired :icon_biggrin:
what Greg needs is a gantry table with extra axes, but I don't have that erector set so i'll get the software dialed n if I'm confident, put together a hardware order with His card :laugh:
this is my 5-6th bot build, the arm was originally conceived as a tracking platform to launch model rockets, or 4th July mortars at drones :icon_biggrin:
-
Ok, that looks exactly like this one....

:laugh:
saw the show, for some reason I equated that show with 3rd rock sitcom
btw, his has 6 joints, I'm a light-weight at 3 (with LOTS of torque:) :icon_biggrin:

Just don't program it for the screwdriver move!

:laugh:
I code like I "design" amps, steal cool stuff, stitch together, call it mine-ish :icon_biggrin:
feel free to edit what I have so far, which is nothing :l2:
(didn't bother formatting the txt file so there's wrap around)
-
the things you forget :think1:
been over 40yrs since I last laced anything, not a very good comeback but hey, I'm trying :laugh:
I blame it on the So. GA chiggers I'm combating :cussing:
-
Finished the octopus, wired it to the uP board, not authorized for LVpower til morning :icon_biggrin:
software :cussing:
-
Looks like a big light dimmer! :l2:
-
The tea bottle for overflow lube?
Jim :icon_biggrin:
-
a big light dimmer
overflow lube?
It's my camo-bong :icon_biggrin:
those motor controllers are fused at 25A ea, that's ALOT of dimming :icon_biggrin:
-
got tired of holding n swapping wires to switch direction :think1:
cobbling a PS together that will power the uP board (9vdc) and the motors (12vdc)
the cute C_made boards were $8!
still need to load test, add some front panel switches for direction, n more
both boards read 98.2% of Fluke so that's a good start
-
Ok, that looks exactly like this one....
Jim :icon_biggrin:
"'cause that's all you needed, right?" :laugh: :l2:

I'm in So. Fl, you can find humans WAY less expensive than this project :icon_biggrin:
Gotta say not many ppl stop and ask questions though and I shower every day :dontknow:

That episode is such a classic!
