Ron, since you have done some of these so you might be the one to ask.
How do you pick a torque for the Compact5 or for any lathe?

With the Emco I have had good luck with anything over 150 in/oz , I prefer the Pac Sci 252 in/oz
This gives plenty of torque so you don't loose steps if the cutter gets a bit dull or you take a bigger bite than you meant to ( that would never happen would it ?)

Besides the
Emco, I would also like to convert a Harbor freight combo and possibly a
Rong Fu mill for CNC. The lead screws would eventually be Ball Screw so
the load of the thread would be minimal. I assume the stepper would be
direct drive to the screw.




No not usually they are geared 2 or 3 to 1
My big mill is 2 to 1 with 640 in/oz using Gecko 202 at 60 volts


Can a torque be measured empirically by making
a heavy cut?

The steppers on the Emco are a Warner Electric variable reluctance unipolar
stepper # SN-072-0060-RA 2 amp -9 Volt probably on a 23 frame. I suppose
I could try to stall one and measure that torque.

Hi Dick
That mostly depends on your needs and the stepper driver that you are
using.
The 65V. is not necessary except to achieve maximum RPM .
These motors will run from around 30 to 80Volts , using Gecko drives I
would suggest around 50 to 70Volts bipolar for best power and unipolar
for greatest RPM but a bit less power.

Can any body help?

My first conversion I spent months trying to decide what to do and how to do it what brand of this and that to use , now that I have gotten past all that I can convert one in 2 days .
It really is a piece of cake to do , if I could figure out how to give you my knowledge .

Thank for the information.
I'm going to convert the lathe as soon as I can fine the time.
I think I will wait and get the Gecko drive (203) which in available Dec. 22.
May have more question after I get in to it.
Thanks again

Hi
Yep, the power supply works fine .There is a plug on the bottom
with the
50V and 12V
Use the Gecko 202 or the new 203.
Go to the Yahoo group emcocompact5users and join , in the photos
section
you will find one called "rons conversion" photos of one of my
conversions using the stock PS an interface board the Gecko 202
drivers
Mach3 (free to use until you are ready to buy )and Pacific Scientific
motors from eBay ( $25 each ).
I have 3 of the 5PS's setup this way and they run great , on one I
hold
+.0005 -.0000 all day long and one runs +.001 -.0000 all day , the
third
one just misc. whatever whenever needed . If I remember right you
will
end up with 24,000steps per inch in Z and 48,000 steps per inch in Y
(diameter)
I have 2 of them hooked up so the program turns on the spindle and
mist
coolant on and shuts it down at the end ( this is REALLY nice)
I have also been able to sell the boards and motors that you will
remove
for enough on eBay to pay for most of the conversion.(my first
ones came
to more than the conversion)
If you need better photos or help let me know.
PS. I used the Campbell board on this one but it is a bit of over
kill
the one from CandCNC works fine and is cheaper.

Re: PowerMax ll Stepping Motor (Power Supply Volting)

cadewey@sprynet.com <cadewey@...>
 

I would like that a lot as I have maybe 5 of the lathes to do for the
school and 2 or 3 F1 mills. Lets see . . . Kentucky is south to St. Louis
then turn left at the Alton sail bridge, I think.

UL approval for F! and Compact 5?

mcpaper1 <lee@...>
 

Does anyone know whether the compact 5 and the F1 have UL approval?
I am the studio manager for industrial design at Mass College of Art
and another school has these available as surplus but they have to be
UL approved to plug them in.
Lee McDonald


Re: EMCO F1 CNC Serial cable

Don Grubb <teachdg@...>
 

The serial cable for the F1 mill is commonly called a
null modem cable. Two of the wires on the cable are
reversed in their connection to make the cable a null
modem cable. I also believe that you can use a null
modem serial adapter with a standard serial cable.
The adapter makes the wire switch before entering the
cable. An web search for null modem cable pin outs
will give you the configuration you need.

Hope This Helps

pc turn 50

tom_cnc_texas <tom_emag@...>
 

New here.

Dose anyone have a pinout for the connectors on the stepper driver
card in the PC Turn 50? A schematic for the board I presume would be
too much to hope for. Just got a turn50 and I'm trying to see if I
can use the existing drives and axis motors or go from scratch.

Has anyone tried to drive the stepper drivers directly from Mach?
Thanks...


LAPTOP WITH CNC5 SOFTWARE Loaded and running plus MANUAL

John <fik123@...>
 

The Lap top is an older gateway, it is configured to run the EMCO
software on boot up. and runs fine. The batteries do not hold acharge
but the ac adaptor works perfectly. I have the Diskettes and the
manual with the exercises in it. I never got the hang of this
softweare. Easier for me to program by hand. The software cost $1500
from EMCO. I will sell the Laptop, battries, charger with the EMCO
software including manual for $500 and I will pay the shipping to you
by US MAIL priority or trade it for a turret if someone has one they
are not using. The laptop will recieve and send to the CNC5 I will
also include a short cable. You will be able to write your program,
load it into the lathe, modify it on the lathe if necessary then send
it back to the laptop and save it again. NO need for tapes.
IT is an older laptop as I said and may not have compatible floppy
format with a newer machine. There is very little other software
installed (windows 3.1)memory should not be a problem., or you could
delete the windows partition and just run pure DOS.
I use MACHINE LINK. (ON EBAY OFTEN FOR $75) IT is almost automatic and
lets me save long file names etc.
I will be selling some other EMCO LATHE surplus stuff. a plotter, a
Lathe Collet chuck (ER 25),etc. Am looking for set of spare jaws for
the scroll 4 jaw chuck, same for 3 jaw heavy duty chuck and mostly a
Turret asembly.
Thanks John

I also have the PC5 manual and software. the latest upfgrades for both
of these bfore they quit issuing it.
I may still have the F-1 programming manual for the software, but not
diskettes.
This i
All one package.

compact 5 cnc mark 1 stepper motor wiring order -problem

sorvipulma <sorvipulma@...>
 

At first, sorry for the horrible subject line - I'm new here...

I saved that c5/m1 lathe from being thrown away by it's previous
owner, who never has been using it so he couldn't help me.

Problem is both stepper motors (or at least I assume so...). When I
try to hand feed those via the control panel by one step at the
time, they turn nicely - most of the time. When trying to drive
continuous movements, they don't roll around but turning back and
forth. Might well be that both steppers just are broken, but I still
hope it could be very simple problem: wrong wiring order.

Could someone who knows or owns similar lathe kindly check steppers
wiring order for me? As said, lathe is emco compact 5 cnc and first
generation model (only 12 G-codes on panel). From lathe comes six
wires; blue, light purple, orange, brown, black and dark purple (or
at the plug end of that wire are eight connectors; a1-4 and b1-4,
order of those relatively to steppers ones goes as well). Steppers
has also six wires; yellow, white, red, brown, black and orange. The
question is only what is order of those wires, so which goes to
which?

Thanks,
Mikke from Finland


Re: compact 5 cnc mark 1 stepper motor wiring order -problem

Ron Kline <ronkline@...>
 

I would check to see if the motors are rotating freely , the motors or the slides might have rusted .
The easiest way to start with is just to put your finger in underneath where the motor bolts onto the machine , there is a cog belt that connects the motor to the lead screw and with the machine OFF you can use your finger to turn it and move the machine .If it moves easily all is fine , if not you can remove the motor by just removing the 4 screws and lifting up a bit then you will have better access to the lead screw and you can then try jogging the motors from the control panel and see if they run smooth.

Hi!

That was the first I checked and slides move mechanically well, so
the problem isn't there. Of course the computer electronics may be
corrupted, but I hope it's only in steppers. I wouldn't like to test
all tens of thousands variations of wires...

No mine is also a 3 phase.  Uses a single phase 120v input with an inverter.  I’ll upgrade the inverter to a Yaskawa also.

the problem isn't there.


I thinkn somone has uploaded the touble shooting diagnostics manual.
IF it is there in the archives it wil step ypu step by step through this.
I suspect coorosion and loss of power in the wiring or boards, A good
cleaning might cure it.
IN the manual it says if motors run single step but NOT in RAPID, to
check for poor connections on plugs.
IF you take one plug at a time off and clean it with some alcohol then
put it back on and test you should be able to find the voltage drop.

3 CNC5's and 1 F-1 MIll for Sale (PLUS LOTS MORE)

John <fik123@...>
 

HEre is my idea folks.
I have three fully functioning good working CNC5 lathes and one
converted F-1 Mill ( AHHA CONVERSION)plus enough spare parts and to
build or maintain a CNC5 forever.

I am thinking that a lot of you know each other from this group and
would enjoy a reason to get together and talk shop.

I want to sell all my emco machines, the laptop with software
installed, the many many spare parts all as ONE PACKAGE ONLY.

IF some of you pool your resources and plan a trip t Seattle I coulkd
ship it al there pretty inexpensively ( I am in ALASKA)

There are 2 spare version 4 motherboard, a spare set of freshly burned
emproms.
Guys there is ton of stuff here, ER25 colets, double sets,
The F-1 has 9 Tool holders.
There are two spare stepper motor boards, two Turret boards.
I won't list it al here, Iam going to put al the photos of everything
up on a temproay webpage with a complete list of everything.
BUT!!!

I am not wiling to part this out, piece it out.
IT took me thirteen years to become totally self reliant with these
machines and I am only willing to sell it as a package. IT won't do me
any good to sell it piece by piece and in fact would just be a lot of
work.
So get together, scheme a trip and lets get these to some folks who
been wanting an excuse to meet, share stories and pick up a very
comprehensive colection of EMCO CNC5 machines and support parts.

PLEASE< honest, PLEASE don't write and ask me to sel you a part or
stepper motor. I am not going to break it up.
IF when you guys get it you want to piece it out that is fine with me,
I need to move it the best way possible and that is al at one time.
IF there is enough interest I will put up the webpage, if there is no
repsonse or I get a lot of mail disregarding that I am not breaking
this up, then I won't sell it here and will list it at full pop on EBAY.
THIS IS NICE EQUIPMENT HAT WORKS PERFECT.
I have upgraded my machines and downsized my product line so I have to
downsixe a huge dent in my toys.

Thanks for understanding. I just finished photogrpahing everything
this A.M. and making a full list wth part numbers so I am not quite
ready to post a page of fifty or sixty pictures.
Let me know if there is interest.
The price will be $12K for everthing. I haven't added it all up yet,
found I had way more tha I even remebered.
