Ping Iggy. Advice needed. [Long]
 

Hi Iggy.
I inherited a year or two ago, a nice Shizuoka ST-N CNC mill. This is a
3-axis machine with a nice large CNC rotary table giving it a 4th axis. It
was given to me by a good friend who couldn't fit it into his workshop. It
has low hours and was only ever used for machining acrylic.

This Japanese machine was originally sourced from and fitted out by a UK
company, Matchmaker, who fitted an unknown control system with arm mounted
CRT and button panel. The only thing we can easily recognise in the bird's
nest that is inside the control cabinet is the 4qty, Westamp PWM servo amp
model no. 30060-3. I take it that this means we have servos rather than
steppers? This makes sense as they (large) motors have 4 brushes. I think
they have 2-wire tachos built in too. I'm not sure what encoders we have yet
as they haven't been stripped out for identification.

The control system is dead. The CRT is dead, and I don't trust the Westamp
boards. However we'd probably keep the big DC PSU, buy 4 new servo drives
and fit a variable freq drive for the spindle.
This brings me to the big question. What controller should we choose? We'd
like to do as you have done, and use EMC2 on a (Linux?) PC, but don't have
any idea of what controller we need for the 'bit in between'.

I'd appreciate your advice on this if can spare a moment.

Many thanks in advance.

JB

Awesome! I am envious.

Most likely servos then.

JB, you are on a good track. You have a great machine with a great 4th
axis.

The control is junk.

You need to subscribe to emc-users mailing list at

https://lists.sourceforge.net/lists/listinfo/emc-users

Then you need to go slow and identify your hardware (what servos? What
voltage and current?)

Try to find a schematic of the mill, if you can, pre-retrofit. It will
help you identify wires from all opints like limit switches, valves
etc.

What you want is certainly doable, will probably take a while, but can
be done in steps where the result of each step is verified. For
example, you can hook up one servo motor to one servo drive, and
"drive" it by selding a signal from a battery to the niput of the
servo drive.

Try to identify your servos first.

You may reuse things from the old control, such as relays, power
supply, and possibly even servo drives.

No it doesn't have a toolchanger! You can relax guys. We did also have to
hire a big truck with a crane to collect it. It's a bit of a monster but I
think it will be invaluable. I'm in the process of building another trike.
This one for my wife. A BMW K100 bike mated to (probably) a BMW E36 back
axle. I have done a few and i've often cursed te lack of a CNC machine.
Milling **** out by hand and doing all of the inevitable 'fettling' is a
time consuming job. Much better to squirt the design over a DXf (I hope!).

By the way, I looked at pictures of Shizuoka ST-N mills, they are
great, but in fact very comparable to my Bridgeport. Mine supposedly
weighs even more, 5,500 lbs.

This obviously would not be a great way to compare wives, though

Ive just recently downloaded the emc software and planning to eventually use
on a lathe, ( tsugami type super preciision chucker )

--good possibility I will end up using geck amps to drive some motors that
i've had kicking around here for some time now...I need to double check if
they geckos can handle it--they are glentek @ 7 amps appx IIRC w/2500 count
encoders....

Looking to keep the hardware as simple as possible and it appears that if I
go this route then everything can be run off of the existing parallell port.

if
they geckos can handle it--they are glentek @ 7 amps appx IIRC w/2500

port.

Servos?

Yes


( brush DC, there is a tach on these that will most likely not be needed and
there is an encoder like I say its probly 2500 per rev )

I'll try and reload the ubunto disc soon but IIRC its the basic NIST is all
I really need here this will be a gang tool setup.

( "soon" to me sometimes takes a year or so just so you are aware )

Or it might be in just a few minutes...

Once, I was rear ended--I took a pretty good hit...seems like yesterday but
that actually happened more like 15 years ago.

Yes




Then why exactly do you need gecko drives?


Seems all Gecko drives accept is stepper input, which is the basic output
from EMC....however, Gecko also has drives which will drive a brush dc
servo.

Allows you to also toss the existing drives by eliminating the need for
additional DA converters or motion cards.

With these sorts of projects, you need to be dogged, overcome
obstacles, and dig deeply when you have problems.

The latest 10.04 disk with EMC is a great system and works very well.

EMC supports DC servo drives natively, with or without tachometers.

You need to take a good inventory of what you have. I would also
suggest to keep notes, in a spreadsheet or just a notebook.

Pretty sure it's not needed for a simple 2axis gang tool lathe with

enough pins as is.

Needless to say, I absolutely require closed loop position feedback....so if
the encoder is is being interpreted by linux, instead of by the gecko then

By the way, I looked at pictures of Shizuoka ST-N mills, they are
great, but in fact very comparable to my Bridgeport. Mine supposedly
weighs even more, 5,500 lbs.

This obviously would not be a great way to compare wives, though

It would be a very dangerous way to compare any wife! I'm not going to risk
