im trying to make my laser tube on/off using z axis dir (controlled with mach3).
when im pressing the test button on the power supply there is red led turning on.
i wired z axis dir to the high ttl on the power supply and when z axis, and when z axis goes down the led turning on, and if z axis goes up the led turns off.
i guess that the signal is ok but still the laser tube not fires!!!
please HELP me!!! i attached wiring diagram.... and im sorry for my english

For those power supplies I think you need two inputs. The PWM and trigger. I can't tell you exactly as I have an analog supply and use LinuxCNC. However you may find useful information about the wiring if you search for LinuxCNC (the wiring will be the same)

I did a quick google.
Some info:
DC-K40 Laser conversion issue
laser setings
The Laser Project.

I wouldn't change to an analog power supply, once you get yours going to will be much better.

However, read your post more. It sounds like a problem connection to the laser. Can you get the laser to fire at all? So an LED on the powersupply comes on when expected? Check the high voltage and ground connection to the laser.
Can you take some photos of your wiring please.
