Hi,
no. The ACK250 is a motion control device. LTP2 requires Machs parallel port driver which is also a motion control device.
Mach can only have one motion control device active at once.

I'm not familiar with the ACK250. Can you post a manual? Does it have spare inputs? The only pic I've seen of it suggests it might.

hi

sorry for my error, not ACK250, AKZ250, leafboy77 motion card.

i would like to connect  standard MPG not USB MPG, but i need alot of input.

AKZ250 have 16 input, i need:
 3 input  for select 1-10-100,
 4 input for X,Y,Z,A
 2 input for Encoder A e B

total 9 input, half board input.

Hi,
you have enuf inputs why not use them.

There are a couple of ways that you could economise on inputs.

For instance you've got three inputs for 1,10,100. If you had a push button and you pushed it once the machine would cycle to the next level, from 10
to 100 say, push again, from 100 to 1 and so on. It would require only one input not three and be nearly as good.

I notice also that you have 4 inputs to select x,y,z,a. You could reduce that to two inputs say I1 and I2:
I1 and I2 off means x
I1 on and I2 off means y
I1 on and I2 on means z
I1 off and I2 on means a

Still if you have enuf input as is why bother to make things hard?

Hi,
sorry my slang enuf=enough.... so you have plenty of inputs, more than is required.
