More VSD-e questions

[scrambled]

I have finally been able to work on my plasma cutter. I have everything connected that I can think of.

But I still can't get it to move.

I am using a BOB from Candcnc, and the parallel interface board, and the 4 VSD's.

I installed the parameters in GDtool for the interface board, and I installed the jumper to disable the charge pump.

The Blue LED is on, so the drives are in the ready condition.

Using a multi-meter I can see a 5 volt change when I press the arrow keys on Mach. I see this 5 volt change on the MTA BOB from CandCNC. This MTA BOB is what connects to the Parallel interface Board.


Am I missing an drive enable or something else?

Do I need to connect anything else?

I will try to upload a picture of the wiring tonight when I get home.




Thanks for the help

Here are some pictures of the wiring.

Let me know what you think and/or any ideas.

Steve,

Why are you attaching the MTA BOB to the VSDEPI?

Have you tried connecting from your computer parallel port directly to the VSDEPI?

Jeff-

I am connecting the VSD parallel interface board to the MTA because I am wanting to use the digital torch height controller that Candcnc has.

I have not tried to connect the VSD parallel interface board directly to the computer parallel port (yet), but that is probably going to hapen in a day or so if I can't figure this out.

I am thinking I need to use the pin #14, which is "Drive enable from PC." I am just not sure where it goes.

The charge pump is on pin #1, So I am not sure about this one.

Steve,

Do you have the schematic handy for the MTA BOB?

Jeff-

Here is the link to the manual. This is a different version, but it is close.

Steve,

What are these connected to?

See attached image.

I don't believe the VSD E common is +5volts

[jalessi]

How are you providing the charge pump signal to pin1 on the VSD parallel interface board ?

Are you using the xml file for the U-Bob?

Jeff...

Do you have "J3" set to pins 2-3 for common ground?

See attached diagram.

Steve,

Do you have a instant messenger?

Jeff-

In your post #7- Those wires are "Common"

For the charge pump for the VSD, I installed the jumper to by-pass this. Once I get everything running, I will install it.

I will have to check the Jumper 2-3 setting. I think this is set correct, because on my multi meter I can see the +5 volts for "direction" for each axis.

Which xml file are you talking about? I set up the candcnc bob acording to the instructions, and I am using their plug-in for Mach3. This sets all the ports and pins.

I will set up a instant messenger. Do you have one you like to use?



Thnaks for the help
