Hello.

I have one question, is possible use 2 Pluto board in the same computer, with 2 LTP ports.

I already search this info and every one says this is not possible.

But all just try put these 2 boards into step or into servo mode at same time.

My question are, Is possible use 2 Pluto board in the same computer one into step mode and other into servo mode?

Or else one pluto board into step mode with encoder input?

Thanks.

I think it should be possible. They use different drivers and different pin names. The two p-ports will have different base addresses, so I would be optimistic.

Can you borrow a second Pluto board to try it with?

Thanks for your answer.

Is because of that i think this will work.

But i need one confirmation if this setup will work, before buy other board.

the delivery to my country will be 3 times the price of the board.

Even the chap who wrote the driver is not sure, but thinks it ought to work. The Pluto web page says that one per parallel port "should work"

However, it would be a much better idea to spend just a little bit more on one Mesa 7i43. That gives your 48 IOs and a huge range of stepgens, PWMs, three-phase PWMs. encoder counters, etc etc.
www.mesanet.com/ (look under "anything IO boards"

The 7i43 plugs into the P-Port like a Pluto, and costs $79.

You are right.
