Re: cheap retrofit with the Allegro UCN5804B chip

vjennuh <e.j.l.bosboom@...>
 

Hello,

This is my first real post here, but Im also planning to control my EMCO CNC to Mach 3. So the EMCO will have to "understand" step and dir signals. I'm planning to do this with a microcontroller connected to the emco stepperboard.
Now I was wondering if it is possible to do half-step in stead of the normal full step control. So instead of AB - aB - ab - Ab will it be possible to do:
AB - B - aB - a - ab - b - Ab - A

I think this would be great to enhance the accuracy of the machine.


Thanks,
Lars

That is a neat solution. Thanks for the link.

Hi Walt,

Now I think you don´t need a UCN5804B at all.
Checking out this project: www.stmental.net/~dfoster/emco
I must conclude that the EMC2
software is capable of generating "A B" signals through the parallel
printer port. These guys made a simple circuit that inverts these
signals so now they have "A B !A !B" signals that can be connected
directly to the stepper board.

You would only need a UCN5804B (or a self programmed micro controller)
if the software can only generate Step/Dir signals.

Kind regards,
Henk

Thanks Henk. That's good to know. I was too lazy to drag the control
unit away from the wall and check.

I would put the UCN5804B right at the connector because I think the
circuit is at risk to be noise sensitive. I also think opto isolated
step and direction signals would be required.

I was surprised how expensive the UCN5804B is on Ebay. I think I'll
post a schematic of how this function can be done with discrete logic.

Best regards,
Walt

Hi Walt,

The ABCD inputs of the stepper board go directly to an onboard
74LS38.
So there are no pull-up nor pull-down resistors.
Therefor a UCN5804B can be connected directly to the stepper board,
although you could consider decoupling with opto-couplers.

Peter,

You should be able to find schematics in the files section of this
or
the F1 group. I'll summarize what you will find.

There is a six pin connector for each axis on the F1 Stepmotor
board.
They are designated X34, X35, and X36. The pin #'s and labels for
each
axis are:

Pin Signal
1 5V
2 GND
3 C
4 D
5 A
6 B

The ABCD signals match the UCN5804B data sheet.

You may need to add 5V pull-up resistors to the outputs of the
UCN5804B. I don't know if the Stepmotor board provides them.
Hopefully
it doesn't have pull-downs. You may also need to provide an
intermediate buffer (CMOS inverters would do) to provide some noise
margin due to the Darlington transistor outputs of the Allegro part.
You want the logic zero output to be well below 0.8V.

The EMCO system uses the "two-phase drive sequence" described in
the
data sheet.

Good luck with your conversion.

Walt

Re: Welturn Software

Vesa Korhonen
 

Hi fellow Emco users,

Have you tried the following link for the WelTurn / WelMill / WelEdit software:

http://web.archive.org/web/20070530001418/http://www.welsoft.co.uk/download.html

I haven't been able to check if these versions work with your machines, as I still use the original versions on my Compact 5 CNC lathe and F1 CNC mill. Eventually they'll be converted to Mach3 / LinuxCNC / PlanetCNC controls with servos. But from the Wayback Machine the old Welsoft programs seem still to be available.


Cheers,

Vesa (from Finland)

Re: Turret working but...

Hi Mike

Some time ago someone had milled a groove in the saddle to allow an extended tool to pass over when rotating the turret, they said there was ample material but check for yourself, it may solve your problem.

Re: Emco CAD Cam with new PC?

Henk Verschuren
 

Hi Cam,

I didn't try myself, but according to the messages DOSOX will run under WIN7 (32 and 64 bit).

I am using the Emco Basis CADCAM that you will find in the files section: FILES >
'Emco compact 5 cnc lathe' > '5CNC.ZIP'.
Speed is not really an issue I think. Any computer will be much faster then the 'original' ones.

One of the users hacked the program so it can send files at 9600 baud (in stead of 300). I didn't try it yet though.

Regards,
Henk

Re: Emco CAD Cam with new PC?

Peter Keizer <keizer.peter@...>
 

I'm not sure whether the CADCAM software works the same as the emco 5 PC software, but if it does, I never run it from win xp. I actually made a boot disk. Which boots that software from the hard disk when the cd is in the tray.

This means that if I put my boot disk in the tray and start up my computer, it will load emco's software. Straight from dos.
If I don't put it in the tray, my computer will boot windows.

I'm not sure if I have the image for that disk. Perhaps I can make one from the cd that I have made.

Hope this message helped you a bit..

They are designated X34, X35, and X36. The pin #'s and labels for each
axis are:

Pin Signal
1 5V
2 GND
3 C
4 D
5 A
6 B

The ABCD signals match the UCN5804B data sheet.

You may need to add 5V pull-up resistors to the outputs of the
UCN5804B. I don't know if the Stepmotor board provides them. Hopefully
it doesn't have pull-downs. You may also need to provide an
intermediate buffer (CMOS inverters would do) to provide some noise
margin due to the Darlington transistor outputs of the Allegro part.
You want the logic zero output to be well below 0.8V.

The EMCO system uses the "two-phase drive sequence" described in the
data sheet.

Good luck with your conversion.

Hi guys,
While searching for a cheap (an temporary) way to retrofit my F1
(and
maybe also the 5CNC) machines i found this old message here on the

"Hi
Funny, this seems to be the first post :)
A little background on my experiences.Okay, I own a F1 CNC mill for
about four years now.The native programming for the F1 is in a word
SUX.So, I look around and found the company WelSoft,its
www.welsoft.co.uk and looked at their Wellmillconversion board.
Simple
thing methinks, butgodalmighty aint they expensive!!!So, I do a
little
research on the way the wellmillconnected to the emco. Having a
circuit
diagram forthe F1 helps a lot :)
Lo and behold, I came up with a design that worksfor the past 3
years.
I use Allegro's UCN5804B chips for step/dir control,TurboCNC from
DAK
engineering for the Gcode to Step/dir translator,DeskProto for STL
to
GCODE translator andSolidworks for design.
If anyone need some help...
Gelandangan."
I have searched in google, i have read basically every message up
here
and also the EmcoF1Mill group.But i couldn't find any good
explanation
of how to do this.
It seems that it's possible to actually use the Emco stepdriver
board
and the original drivers.Then you just hook up the machine to your
pc
and use it with Mach3 or whatever and use it like that.
Is there anyone that knows how it works or can be done?
I've already ordered 3 of those chips on ebay, since they're very
cheap.I wasn't sure whether i needed 1 chip per axis, or one chip
per
machine.
I hope one of you guys can help me out!
Thanks a lot in advance!
Peter Keizer.
(I'll be posting this same question in the EmcoF1Mill group.If we
can
figure out how it works, i'll make a nice tutorial of it so others
can
do it as well.)

Hi Walt,

The ABCD inputs of the stepper board go directly to an onboard 74LS38. So there are no pull-up nor pull-down resistors.
Therefor a UCN5804B can be connected directly to the stepper board, although you could consider decoupling with opto-couplers.

Kind regards,
Henk

Hi Mike,

That's why i'd like to make a tutorial after i've finished it.
So people like you can also do the trick with a proper manual.

It's not thanks to me, but thanks to the other people out here who know how to do this.

Wire color coding for spindle encoder

greenbeancnc
 

Happy new year to all.

I'm hoping to use the original photointerrupter for the spindle encoder on a Compact 5 PC.
Unfortunately, the connector plug to the back panel of the lathe is gone so I'm a bit baffled which color of wire in the cable going to the sensor corresponds to each function.

So I believe I need: +5v, ground, sync, and count.
And the cable has three wires (green, white, brown) and a shield (I believe the shield might be used as the ground?)

If anyone might know the color coding of these wires, it would be most appreciated.
Cheers, Steve

Hi Walt,

Thanks a lot for your reply.

I've also contacted the original poster of this idea, Gelandangan, and he
also replied to my mail. I've asked him in which way he used the chip
and he came up with this reply:

"LOL
That post was made almost a decade ago! I have not used the F1
controller for 8 years now.
Ok, what I did at the time was to figure out the point where the native
motor driver of the F1 gets its pulse signal (connectors x34, x35,
x36).and use the UCN5804 chip's output to feed to it.So in effect, I
get the PWM of the native driver, yet using the Step/Dir translator of
the 5804 (5804 is not a PWM chip).To do this, simply wire the outputs
ABCD of the 5804 to the corresponding connector inputs ABCD of the
respective F1 connector input.
Now days, I use Gecko Drives to drive the motor, and I have replaced my
motors to much larger/stronger 300 oz.in ones.
Good luck!Gelandangan"

It seems like the way he used it is a bit different than the way you
described. But we'll sort that out.
I'll send him an email to ask whether he used it "plug and play" or the way you described it.
I'll also ask him if he's willing to contribute to this thread because it makes it easier to read for other people if all the information known about this subject is in one place.

Thanks a lot guys for helping me out!I really appreciate it.I'm looking
forward to test is as soon as my chips are delivered and i'm also
looking forward to make a tutorial for others!

Regards,
Peter.

p.s. i've also replied to the thread at EmcoF1Mill group.
