Anyone ever used the CIB Industrial Control Interface board from Zapp Automation with Mach3 software?
What do people think of the board?

Ant never used that board, but it should not be used with stepper drivers that have opto-isolation as well.

Industrial control interface AKA breakout board

What is opto-isolation?

What is opto-isolation?

Instead of there being a direct electrical connection between the computer and the driver the connection is effectively split with light bridging the gap. The opto-isolator uses an LED and a phototransitor to sense the light. If there is a high voltage on the motor side of the board it cannot reach the other side since there is a physical gap (within reason).

Google it...

You could get round the 'problem' of having both the driver and interface board isolated by buffering it - few logic gates, maybe not even that. Or even pop open the driver and bypass the isolation with a bit of wire! Kind of defeats the object of buying it ready made though, and you're increasing propagation delay which may/may not be significant.

yes it can be used with stepper drivers that have optically isolated inputs.
Any driver that is worth buying has optos built in.

I was going to use these stepper drive units. It does mention opto-isolation. Will they be ok?

Also whats the reasoning that I can't use the opto-isolation. I've googled it but seems to be no-reasoning. In what solution would you use opto-isolation?

Thanks

They work fine with the CIB.

I wasn't thinking last night, disregard what I said earlier. I posted this diagram somewhere on the forum a while ago which shows how to do it:

Connecting the CIB to any of our drivers is very simple.
Connect pin 9 (5V+) to the positive side of the Clock, direction and enable and then connect pin 5 to the Puls, Pin 3 to the Direction and pin 1 to the enable (Free-)
