Thanks for the good comments. =)

davidimurray: I don't know the name of the machine in English. If you're friend wants pictures and maybe some ideas just mail me.

Now I have some pictures on my electrical encloser. Its almost finished =)

Not much to say yet, I´m in the middle of the electronics.

Here Is what i started with, and finally how it looks now.
Coverplates Not mounted in the pictures. Also the emergency button not there.

Thanks Chaoticone, I get signals for cw and ccw. Just one more problem. I only have 0,07v at  maximum speed. But I didn't have much time today to look my set up. I believe that is an simple miscalculation.

I have tried both enabled and disabled the E-stop. Right now I don't have anything connected through the real E-stop, just connecting one thing at the time to be able to measure everything up. What drivers? The breakout board is enabled by a switch now. In "outputs signals" I only enabled output#1 for my start/stop relay.

Its an ORAC. I use the original vfd and step motors. Using Gecko 210 for them.
I got 5vdc connected to the breakout board and 12v to the C6-board. A relay to start/stop the spindle.
At ports and pins I have choose port 1; pins 6,7. Low active.
At the spindle setup I have set: port 1 to the relay, Motor control by step/Dir,
Output signals enabled pin1.
Just consentrated me on the spindle right now, taking it step by step.
Would like to be able to measure the 0-12v output on the C6. But I only get 0v

Hi, I have bought a "breakout board(C10)" and a "variable speed control board(C6)" from cnc4pc.
I have problem to make it work with Mach3. Can anyone who also got the same boards tel me how you have setup your Mach?
I'm totally new too Mach. Even the simplest settings would be helpful.
Thanks/Jim

General Mach Discussion / M3 M4 M5

« on: May 27, 2006, 11:44:32 AM »

Hi,
I´m in  the middle of converting my lathe (ORAC) to Mach3. And now i´m wondering onething about my vfd. It work like this:
 0-14v to set the speed.
Spindle on and off, is connected via a relay.
M3/m4 is also chosen via another relay.

Now the problem, is it possible to set Mach3 that Mach3 cant do a M4 when the M3 is activated? (Must be an M5 before) Because if the lathe is up in 2000rpm M3 I know its not so good if it chose to switch its direction.

Regards Jim

Hi, Thanks for the quick answer. So a plc i what you use. Is it on an ORAC?

I found this in the Turbocnc forum,

----------------------------------------------------------------------------------------------
"The toolpost has a DC motor driving a worm and wheel, and a rachet
with a click for each tool station. On the shaft holding the
toolholder there is an optical disk with three  tracks, and each tool
station has a unique coding on those three tracks.

What Denford did was to drive the motor in the forwards direction
until the correct code was read from the three tracks, then reverse
the motor against the rachet and leave it in a stalled condition.
This way tends to overheat the motor.

My circuit basically does the same, but when 'on station' only
reverses for three seconds then powers off the motor. I find that
cutting forces happily keep the rachet and pawl engaged.

I read the status of the three tracks into the parallel port of a PC,
and drive forwards until I get what I want, then using a 555 timer
run in reverse for three seconds. The motor is driven using an
L298 'H Bridge' circuit."
----------------------------------------------------------------------------------------------

But i want Mach3.
He use the printer port on the computer and runs it macro.
