Hi guys- can anyone help this newbie?

I have built a 5 axis machine- it is for dispensing 2 chemicals into hundreds of little vials. I use the x-y-z commands to position my dispensing tips to the top of each vial.

Now is the tricky part.

I have 2 pumps controlled by stepper motors for the "A" and "B" axis. I tell them to rotate 6 revolutions to dispense the correct amount of liquid.

Now here is the trouble- I have to keep incrementing the pumps by 6 with every dispense. Does anybody know any way to "resent" the "A" or "B" axis references back to zero each time? That way it will dispense correctly and I don't have to add "6" to each event (it's hundreds of lines long.)

Any help would be greatly appreciated!

Mark

Sorry you're feeling under the weather- bet you'll get a flu shot next year won't you!

Here is what I need help with. I sent you documentation about the slosyn 230T. I want to use it with MACH3. I belive the "pin 1" designation for step should be the "PU" outsput of the driver, if we're talking about the X Axis.
Also, "pin 3" should be the "cw/ccw" or direction connection, right?

Now, where I am running into trouble is with one other pin carrying 5VDC to the computer. I suppose it charges the "step" circuit, but am not sure. Which pin should that be?

Hope you can help me with this. I need to control 5 steppers. 3 of them will be for x-y-z type of movement, but 2 will be controlling FMI Fluid Metering Pumps.

Got a great idea herer, but need to contrl these steppers as inexpensively as possible- MACH3 with these "slosyn type drivers seem to be the ticket, but let me know.

Here is the Slosyn 230T documentation.

I want to use these drivers with MACH3 and am trying to determine the pinouts. I'm going to need to control 5 axis' but if I can get one or two on line, I think I can figure out the rest.

I want to use my Vexta 24V stepper motor - 8 leads but I've been running them with 4 only.

REALLY need to get this going.

I'm trying to emulate the wiring of this slosyn to a gecko drive. They seem to be very similar.

It looks like, to make the Y axis move, I need to send 5VDC from the computer to the slosyn, and that will amke the motor move the appropriate steps, right?

When I check the voltage at the "step" pin on the slostn, it reads 5V. Seems like, if my thinking is correct, it should not read any voltage until the computer tells it too, right?

What am I missing.
HELP!

HAd trouble uploading pics, so I published a couple on my company website, www.caisc.com . If you look there, Rich, under the CNC development page, I've posted a motor pic and one of the drivers. I'll add more later.

Does this help?

I've tried to post pics but the will not upload. They're only 2 MEGs but nothing ahppens when I press the post button.

Rich-
Sorry I thought I had sent a post yesterday, but it seems it did not deliver. I'm new at this.
I do have the driver/power supply box hooked up to the computer. I can turn the motor, slowly and very noisily. BUT it will not change direction and the speed is very slow.
I'm getting there, but there is a setting that is not quite right.
I took some pictures and tried to upload them yesterday, but it's not working. Perhaps I can email them to you, or, can you tell me how to successfully upload them?
Mark

Hi all- please help if you can. I am a chemist trying to build an automated dispenser using a CNC approach. I have an older model CNC device, looks like it was build by a c0llege guy teaching a class.
There are 3 slo-syn 230-T's all wired up to some Isert electronic motors.
I'm trying to get just one axis going- once that happens I know I can get the rest of them.
On the slo-syn the outputs are as follows:
PU(step) is to pin 7 of the printer cable
CW/CCW is to pin 9
H/F (half step maybe??) is to pin 8
Logic com is to pin 4
There is a yellow/wht wire going to pin 15. It looks like it has come loose from something, and I think it's important but don't know where to wire it.
+ output of the 5V power supply goes to an org/wht wire, which is pin 14
- output of the 5V power supply goes to pin 4 (tied into logic com)

From this info can anyone help me setup Mach3???
