Laser test fire

Want to put in a remote firing switch for the laser, would make setting up mirrors much better.
No from memory I think it is TL to ground but just wanted to double check.
Cheers
Pete

You can use this 1channel RF controller to do remote firing on your laser machine. It is great for doing mirror alignment

TL to Ground
WP to Ground
A 5Kohm or 10Kohm resistor to the +5V, IN, and Gnd for output current control. Center leg connects to the "IN". You need to do it because you don't want to fire the laser in full power.

Thanks for the Reply Marco, looks very good how is that wired up.
Cheers

See this manual
viewtopic.php?f=16&t=18
You can just hook up the TL to the one leg of the remote control while connect the leg of the remote to the ground of the LPSU. Once the remote relay is latched, it shorted TL to Gnd and fire the laser

Thanks for that Marco, will it still need the resistor ?.

Yes you need a 3 legs 5K variable resistor

Hi Marco,
Got the resistor coming tomorrow and switch, it is a temporary fix now until I change the controller.
You say the centre pin go's to the 5 volt positive, I don't use that on my laser power supply as the current board that is not needed.
So will I have to get a 5v supply ?.
Cheers
Pete

Pete:
Please review the power supply connection diagram that I sent you.
You use the remote control to turn On/Off the "TL" to the ground. Once TL is grounded, it fire up the laser and the power is controlled by the 5K VR. The center leg is to "IN" (I didn't recall I told you to connect +5V to the central). Let's say Pin1 is connected to the ground, 2nd pin to "IN", and the 3rd pin is connected to "+5v". It is so simple and if you don't understand, I don't know what else I can do. The diagram explain pretty well.
