Title: milltronics gig
Post by: shooter on September 09, 2019, 06:14:37 pm
 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:

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:

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:

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
