What is happening with the tape unit? mechanical or eletrical?
How did this affect the main motor?
This is the exact thing I am hoping someone will see.
I have three working CNC5's and enough boards sdpare tape drives and
motors to make another CNC5, if enough of you get together you could
buy me out and put all your machines back in working ordrr. I am
notinterested in parting it out, but there is enough spare parts,
motors, boards to repair two complete other lathes besides the 3
working machines I am selling.
Talk to each other, lets make a deal I want to ship one crate of al
EMCO stuff to Seattle or LA or SOMEPLACE and you all can divide it up,
SRIOUS ther are 2 spare video boarsds, 2 spare turret boards, 4 CPU"S
two of which are mark 4, 2 stepper boards, one main motor board one
power supply, all the wiring harness, sapre amp meter keyswitches.
THIS IN ADDITION TO three working CNC5 last version. two with turrets.
ONe with a 3 inch Northfield Air Chuck. 2 ful sets of Colets. THE F-1
is convereted to AHHA. has 9 tool holders.
I have downsized my operation and upgraded my machines, this al has to
go. I want to sell it to you guys o here, but only as a package. MY
other choice is to send it off to an Auction house whwere you will be
paying top dollar. There is one brand Z axis leadscrew, a spare cross
slide. MORE STUFF THAN YOU COULD IMAGINE. A FIELD DAY FOR A EMCO CLUB.
I AM AKSING $10,000 plus shipping.
Gold mine of EMCO stuff.
I am going to give it one more week then calling Relaible and consign
the whole works to them. get it while you can guys.

Does anyone have or know of where i can obtain the following parts
please for my compact 5 cnc mk2
Tapes???????
Tape unit and boards????
Main drive motor (dc)

Your machines are mark2?
IT is unlikely that a tape drive from a newer unit will work. The
format is different on the board and it will just give you errors.
You can't run a program from a mark 4 board on a mark2 machine. You
can take a mark2 program and load it in a mark4 machine but not the
other way around.

What is wrong with your tape drive?
As before is the problem you don't have any tape drive? the tape dive
is mechnaicaly broken? is not there at all?

There were two machines recently sold on Ebay. ONe was a newer machine
the other was a mark2 and incomplete. Before that one sold that had no
tape unit in it at all.

The earliest machines did not have RS 232 capability. but if you do
have the DNC baord and the rs232 cable you will have better luck with
that than tapes. IT loads twice as fast, does not have to stop,
rewind, check for errors, then save and rewind again. You can also
make backups to floppies or Cdrom. I recommend spending the money on
"MACHINE LINK" a transfer program. You can then use long file names,
it almost auto configures. Tapes are just a big drag.
So Do you not have a RS232?
For $75.00 you can get machine link on Ebay a lot of times, I know
there are lots of other pr4ograms but I find this one the easiest to
use and configure.
I can't rememebr for usre but ity seems I was using the download of
Demo of Welsoft to save and rs232 to the machine. That is if you have
the DNC card.

What is wrong with the Main Spindle Motor?
Get from Radio shack. Some people on here have said they don't work
for them but I have lots of them and they have always worked for me.

Where are you located?
Didn't you sell or try to sell a mark4 board last year? Seems we wrote
a couple times about a board and then the parts went to Ebay?

Ther is a man selling a chuck on Ebay says it is for CNC5. IT is not.
IT is not new! and is a chuck for the dividing head of a F-1 milling
machine or the manual equivalent. IT will not fit on a CNC5. The
pictures are poor but look close at the jaws and the boss on back. The
jaws have been hit and the boss is not relieved to fit a spindle. Just
a heads up cuz I been looking for a spare heavy 3or four jaw scroll chuck.
Let me know what is wrong with our machine maybe I can help you fix it
without getting any parts. FIK

Hello,
 
Check or find someone that can check the transistors on the driver board.
That has been a problem on 2 of my emco machines.
They were inexpensive and easy to fix.

Hi Leo.

I'm not surprised - they are worked fairly hard and some of the
devices are worked near their ratings. It is fairly basic, and
fixable though - might be cheaper than a new (second hand ) board. I
doubt new boards are available still.

Hey Guys, thanks for the input. It's good to know that someone else has
been through this. I replaced the bottom center connector that had one
side burned off, jumpered a couple of traces that were blown off, and
now have good control on one axis. With proper programming and some
dexterous plug switching I've got a working machine.

Re: A6A113001

The man from Moline knows whereof he speakith.  but here are some part numbers you might need.
 
4xTIP3055-NPN and 2xTIP2955 -PNP  per stepper,  A google search will turn up the Motorola tech data.  For now read them:  Base Collector Emitter left to right, with base on the tab as well.  For a simple test the diode tester on your DVM will show proper polarity.  That is on an NPN (not pointing in) the base will be positive with respect to collector and emitter.  On its compliment, the PNP (piss on plate) will show the base to be negative with respect to collector and emitter.  That is with any simple transistor.   They are on the heat sink in rows of 4 per type.  KEEP TRACK OF THE INSULATORS underneath the screws and tabs and put them back.  The European BD245b means TIP3055  The TIP2955 are usually marked as such. 
Don't take my word for anything,  Get the spec sheet and check everything.  Do not desolder willy-nilly until you have a good idea (smell) which is the bad one.  None of the pins should be shorted and none should be open with respect to the other pins.  Go slow and good luck.

Good information. Checked as best I could and all seems consistent. I
notice that just sitting there with the power on, the farthest leftest
3055 gets hot, as does the X axis motor. I don't know what the PC 829s
do, but I'm getting a resistance reading from one of them that is not
duplicated anywhere else. I may be looking for a professional. Or a
used board for pieces/ parts. I'll pretend that I'm a car dealer and
keep swapping parts till the problem's fixed

This can be quite normal. When you switch on the lathe without putting
anything in the program memory, no current is drawn by the stepper
motors. You can also turn them by hand. I have uses extension pieces on
the spindles of mine, this then allows me to turn by hand if required.
If you go near the programming sequence the motors become active. You
can also switch off the stepper motors using a G code I cannot remember
this at the moment and the lathe is and the workshop.

Re: A6A113001

It is a optical isolator. It takes in a 5v pulse which switches a Photo
transistor inside to trigger the gate of the PNP (not on the heat sink)
that in turn triggers one of the four 3055s. I am guessing that it should
be a pulse and not stay on since it is fired from a nand gate.. On the PC
829 pins one (positive) and two are the led input, Pins 8 emitter, pin 7
collector. base is internal. (Since there are two per chip 3&4 are paired
with 5&6 for another opto isolator.) Check out that LED diode. 5V is fed
to 1 and 4 with 2 and 3 sunk back to the nand gates through a 220 ohm
resistor.

Stepper Motor Gear

nugmancnc <lburchfield2@...>
 

Does anyone know where i can purchase a new stepper motor gear? I am
replacing my emco motors with real steppers and one of my gears is
worn. Thanks Larry


Servicing & milling

Nick Hart <Nick@...>
 

Hi all,

I have been lurking on the list for a year or so - finally got round to doing something with a compact 5 CNC I bought a while back!

I thought I would give it a service before using it just in case there were any hidden problems and it has prompted a couple of questions which I would be grateful if anyone could answer.

The spindle on the stepper motor which drives the lead screw is very free spinning where as the spindle on the cross slide stepper is much less so, would it be worth swapping them around to even out wear?

The main spindle drive motor squeaks when I spin it in reverse but not not going forward, is this normal? The brushes are fine, plenty of wear left in them.

Not having done any programming before I have downloaded all the manuals I can but keep finding references to a "Basis" manual which it says introduces programming to the beginner. Is this available for download anywhere? I might be able to figure it out from the software manual eventually but an easier starting point would help!

Has anyone experience of using the lathe for milling? I have a manual milling head which I could attach to it. Of all the projects I might start with on the machine the one I have come up with is loco side frames....

Thanks
Nick Hart


can't unzip emco cnc5 manuals

rsholl
 

I down loaded the 3 zipped files that lost_guy had posted. I am new to
the group and have an Emco Compact5 lathe that I have had for several
years. I tested it when I first bought it and it worked. I did have a
little trouble getting it fired up after setting for 3 or 4 years but
it is working OK. I was wanting to run a small part but don't have an
operators manual although some paper work came with it. I can enter a
program but do not know how to save it using the tape drive and
couldn't find a thread here for doing that. I was able to download the
manuals OK but can't unzipp them. I get an error message, unknown
compression method. Just wondered if anyone else has had a similar
problem. Thanks, Roy

No display on monitor

rsholl
 

My lathe has a monitor attached to it and the monitor has power but I
never get any screen, it is always blank. From past computer experience
the monitor is basicaly a dumb terminal with a single coax for video.
Is there a key sequence that sends video to the monitor? After
searching I finaly found info to run the tape so I can back up my
files. I looked and I can't find a serial connector on the back. Any
info about the terminal would be helpfull. Thanks, Roy


Re: No display on monitor

Professors <Professors@...>
 

I just pluged an old black and white monitor into the connector on the rear of the lathes back panel.

The monitor comes on when I turn the machine on.  No commands.

Mine also has a Serial connector on the rear.

You might want to check the files section.  There you should find tons of documentation.
