[Emc-users] Wyse S30 terminal as a CNC computer?

[Gregg Eshelman]

Just got three Wyse S30 thin client terminals with Windows Embedded CE 6 Pro on 
them. They have four USB ports, one RS232 DE9, one Ethernet, one VGA, speaker 
and microphone jacks. Geode GX 366 MHz CPU.

For RAM they have a 128 meg PC2700 SODIMM and use some sort of removable Flash 
ROM, 128 meg for the Windows CE 6 version. There was a Windows XP Embedded 
upgrade kit with a 512 meg SODIMM and 512 meg Flash ROM, but no longer 
available new for converting an S30 to an S90.
Preliminary reading on installing Linux in place of Windows CE indicates it's 
possible to install up to a 1 gig SODIMM. WinCE on them has a slider to adjust 
the RAM split between storage and memory. Of course I had some larger than 128 
meg DDR1 SODIMMs until a few days ago when I gave away a large pile of old 
computer stuff.

Finding the larger Flash ROM boards could be a challenge. They plug onto the 
mainboard with a 40 pin header like a 2.5" IDE hard drive, but do they use the 
IDE interface and protocol? A quick look on eBay shows many S90's - in Germany.

I just got lucky (unlucky?). I looked for my first CNC machine for quite 
a few years and ended up paying too much when I finally found one close 
by (Hardinge HNC). (I found the Shizuoka mill on eBay for a really good 
price, but moving it myself was something I won't forget.)

This same friend gave me me two mills and a lathe before:
http://www.wallacecompany.com/old_lathe/
http://www.wallacecompany.com/machine_shop/Std_Engr_Works/
and an old Cincinnati knee mill without a head.

I think he wanted to keep the Tida lathe to use but gave up trying to 
get it to work. (I found a motor starter switch that had burned away 
contacts and other wiring issues. I could have fixed these if he had 
asked but it's too late now.)

The plan is to restore the oldest lathe and horizontal mill, and build a 
new head for the Cincinnati and maybe converting to CNC. Then sell the 
machines that I end up not using.

Hi Peter,
And now I can see the summing is done right with the input. You guys 
knew what it should be and I just could not connect the dots. Thanks to 
you and Andy for sticking with me. Now it all makes sense.

I just found this, don't know why it did not show in all my previous 
searches:


I thought the tach would go to j14 where nothing is plugged in. Sure 
enough the tach wire is hooked to the board, a manual is so helpful. 
What I thought was a strange differential driver voltage was a single 
ended drive and the tach. Yea, they ran the wire up through the Anilam 
board so it confused me for sure.

Today the BIOS battery went dead so I have to enter the proper cylinder 
and sectors drive number to boot. Hopefully I won't have to boot the 
Anilam again, that I have all the info I need now to move forward. I'll 
post my work on the web as I move along.

Thank you very much, Dan.

I have an Automation Direct GS2-23P0 (2.2 kW/3 HP output) on my 
Bridgeport.  It runs on 240V single phase.  It's hooked up to LinuxCNC 
over Modbus.

It's been 100% trouble free since installation 7ish years ago.

[Emc-users] VFD recommendations

[dragon]

I want to start looking for VFDs for my lathe and mill conversions. I
have two 2hp 3 phase motors to use for the spindles. Of course if I came
across a 3hp for the lathe some day it might get upgraded.

Are there any drawbacks to using MODBUS instead of the usual analog 10v
interface?

Does anyone have suggestions for particular brands or models of VFD? I
have worked with several Hitachi and one Toshiba VFD but that is all.
Remember that these are home/hobby machines and I do need to try to keep
costs down, but I don't want to be penny wise and pound foolish either.

Thanks!

I think what may be confusing you is that its entirely possible to have the 
tachometer feedback connected at the controller and have the analog 
subtraction of commanded velocity (from motion commands) and feedback velocity 
(from the tachometer) done somewhere else other than at the drive inputs

The 7i77 doesn't need the tachs if they connect to the drives as
originally set up.

You have two cascaded control loops. There is an all-analogue control
loop with the drives and the tachs in the velocity realm, and then the
7i77 runs a position loop. It compares actal position with desired
position and outputs a velocity command to the analogue velocity loop
(and in the velocity loop the difference between commanded and actual
velocity becomes a motor current).

Hi Peter, Andy,
I found that earlier and saved the pdf pages in case I would need them, 
I did think until today they got speed feedback from the motors. But the 
board's tach input have nothing plunged in, so zero and gain would be 
the only meaningful adjustments. What you write Andy is talking me off

That's the very definition of a tachometer.
A tachometer outputs a DC voltage proportional to speed, and a
negative one for reverse rotation.

What you have is a very conventional (and very effective) system.

The servo amps take a voltage input to command a velocity. This
voltage is wired to the tachometer output, such that if the two are
equal, there is zero resulting voltage. Then that sum is amplified to
servo drive current.

This is all analogue, but means that you have a very stiff velocity
control, with none of that digital-realm PID nonsense.

Separate from that, the new-fangled computer looks at the glass scales
and decides how fast to go to correct the current position error,
converts that to a voltage, and applies that to the amps.

So, keep the amps and tachs, that's actually a good system. Like
resolvers, it hasn't been superseded for being bad, it has been
superseded for being expensive. Put LinuxCNC between the glass-scale
input and the servo velocity command output.

Hi Peter,
This is the board:


I had a chance to buy a manual for $2.00 a page. Maybe it wasn't that
expensive after all. I've searched extensively, there just is no
information on the board I can find. The feedback goes to the Anilam
board along with the glass signals. The computer is full of boards with
lots of wires going to that Anilam board. That board has a lot of stuff
on it. I'll look up some of the chip numbers, early Altera FPGA? I had
no concern about the rest of this system, of course. It was just going
to get salvaged.

Thanks, Dan.
(Sorry, I did it again, re'd without setting up the send to)

The DC generators are the tachometers (they could have no other purpose)
the question is how the tachometer generators are connected into the system

What are the servo drive part numbers?

Well, when I thought this was going to go smoothly, I've run into 
mysteries. At my age you'd think I know better than to assume.

I was working out the details of the current wiring to the Anilam. First 
surprise, there is no motor tach to the servo amplifiers. They use none 
of the PID circuitry on the amp, it is just control voltage in and 
motors turn, a simple pulse width modulator. Next surprise is that what 
I thought were pulsing tachs on the motor shafts are really DC 
generators. I don't see brushes so they must rectify the coil output. 
I'll have to take one 'more' apart to confirm. But the signal is clearly 
DC as I can spin the handle and get about ten volts plus and minus. So 
even more interesting as, 'How do you change the output polarity 
depending on which way it is turning?' !! Has anyone seen a setup like 
this before? I noticed the date on the console schematics are a couple 
of years later than what I think this thing is. The schematic shows what 
look like tach feedback to the amps. But absolutely, they are not there 
on this machine.

So I'm wondering just how well the Mesa system could deal with just 
glass in and motor voltage out. The Anilam does not bounce or even buzz 
on a stopped motor. It just sits locked in place and will fight my turns 
on the handle to stay in place as if a brake were set.

Re: [Emc-users] Tida_TD-1336_lathe

[Peter Blodow]

Kirk,
on my Graziano SAG 12 there is a similar spindle head with the camlock 
fastening system. I made a lot of additional bolts for different chucks 
and faceplates so I had all the parts in my hands quite frequently.
  The locking inserts (nuts or what you call them) in the spindle head 
are excentric in the middle and symmetrical so you can fasten the 
camlock either way, left or right. We are used to tighten clockwise, so 
I prefer this. The bolts are screwed loosely into the plate into 
randomly cut threads and only prevented from turning by an additional 
1/4" bolt, so it depends on chance just exactly how far they protrude 
when screwed in. (To show the desired position, they have a ring groove 
which is supposed to be about even with the faceplate's surface.) The 
excentricity of the nuts and the camlock bolts with their (weird) low 
pitch threads are designed as to tolerate this. Of course, there may by 
no means a gap between the spindle head and the plate. And when 
tightening, the wrench must come to a final position where no more 
movement is possible.

Peter

That photo looks suspiciously like the one on lathes.co.uk
http://www.lathes.co.uk/latheparts/page9.html

And I suspect has been flipped or mis-drawn.

The ISO standard (702-2) seems quite clear that the pins are clockwise
of the cams.

Yes, Or an insert for a different size collet. Typically the spindle
bore is a plain taper (sometimes Morse, often not) and the lathe comes
with an adaptor for a fixed-centre.

There are also D1-4 to 5C adaptors:

I don't know. How interesting.

Are there any marks around the camlock squares? Normally there are
little marks that show when you are in the safe range.

You take out the locking screw and screw the pins in and out to get
the pointer between the marks.

It might be worth getting a good-quality backplate or face-plate to
use as a gauge if you re-grind the nose.
The chuck should pull up far enough onto the taper to touch the flat
face (ie, no gap).

Another thing came to mind, I placed a 5C collet in the spindle bore and 
the hole is larger. Is there typically an insert for this bore to adapt 
to 5C?

Another thing I'm curious about. I haven't used a D1-4 Camlock before 
and I can't seem to find information on how to use it. I did find the 
specifications:
http://www.tools-n-gizmos.com/specs/Lathe_Spindle_Mount.html

but mine is a little different than the one shown in the link above. The 
linked spindle shows the cam is just clockwise of the chuck pin puller 
hole. Mine is counter clockwise which suggests that the locking motion 
is different.
> http://wallacecompany.com/machine_shop/Tida_Samson_TD-1336_lathe/IMG_1774-1a.JPG

Looking closer, the example chuck plate is like mine. The spindle 
picture suggests righty-tighty (clock-wise-tighty), the chuck example 
and my lathe suggest counter-clock-wise-tighty. Do D1-4 mounts go both 
ways? Also, I found information that the pull pins need to be adjusted 
so that the cams will detent when tight. Any help clearing this up would 
be appreciated.

I have a Samson TB 6B 16" x 48" and it will swing a 20" face place with 
the drop bed removed (never done that). Mine is in pretty good shape for 
an 80's lathe and I use it regular. I can't wait to see your conversion 
might inspire me to convert the ole Samson.

Re: [Emc-users] Tida_TD-1336_lathe

[dragon]

Kirk,

You have a big brother of the lathe that followed me home! It literally
followed me on a trailer ;) Your's does look in rough shape.

It is a 1979 Jet 1024P made in Taiwan. It came with a companion, a 1980
Jet JVM-626 benchtop knee mill. While old and definitely used, mine were
very well cared for. I even got a bunch of the paperwork and the
original tools and tool boxes. They both have 1.5hp spindle motors. The
mill came with a 5" riser, 4" Kurt and an 8" rotary table that I plan to
turn into an A-axis. The lathe came with steady rest, 3-jaw, faceplate,
and a spare chuck backing plate.

My plans for the lathe...
- leave the apron on for a bit of extra mass and put ballnut inside
- 3 phase motor and VFD combo
- ditch spindle belt engagement system
- ditch the belt drive counter shaft if possible
- remove the compound
- T-slot plate for top of cross slide to allow gang tooling
- remove power feed/threading gearbox on headstock
- remove all of the threading gear train under the left cover and add
encoder for threading

I have scrounged or found cheap the following parts so far...
- E661 servo motors with encoders
- 30A@60v output transformers
- rectifiers and capacitors
- a couple of almost new 2hp 3 phase motors (free on CL)
- ballscrews for the knee and Y on the mill
- ~750 lbs. chunk of granite to mount the lathe on

Does anyone have a suggestion for somewhere to host the build/conversion
progress and post pictures?

-Todd
