Hi all.

Where to connect the blue and the white wires ?
Do i need to connect the wires to Z(A+) and Z(A-) ?

Thanks.
Pini.

Pini,

A few more details of what you have may be helpful in deciding where the wires go.

Hi Tweakie.
It's an honor for me to get help from you.
I saw your web site...It's used to inspire me.

Attached two photos of my TTL laser and my driver board.
I saw it on your site, but I did not understand how to connect it.
I tried to plug the blue wire to ZA+ and the white wire to ZA- but smoke coming out from the board.
I hope I didn't do damage.

Thanks again.

smoke coming out from the board.

When the magic smoke escapes it's usually bad news!

If you can find the source, it should be easy to repair.

Pini,

The blue and white wires can be ignored if you are just operating in CW mode. If using PWM or switching then the white wire is GND (same

potential as the black wire) and the blue wire is TTL high / low (5V or 0V). If you are switching this from your Z axis direction signal

then the blue wire would connect to the LPT (parallel port) pin that is 'Z Dir' and the white wire would connect to 'GND'.

Hope this helps,

Tweakie.

(hope you didn't do any damage making the smoke).
