Laser Power Supply Connection to Laserboard

[Michael (Michael t Towey)]

New 2-axis CNC laser build with new Cohesion3D Laserboard and Smoothie.

The external driver and x + 2Y motor setup went perfectly and quickly thanks to the driver cables offered.

But I am unsure about the connection between my laser power supply and the Cohesion 3D board.

The 6 pin connector on my Cloudray Power supply reads: H L P G IN 5V

I am planning on connecting the LASER FIRE pin on the laserboard to “H” and LASER GROUND to “G”

I see the Alternate PWM out on the Laserboard and I am not sure if it is prefered.

Thanks for your time, this board is brilliant!

Help wiring a generic 80w lpsu to LaserBoard

Machine: DIY 80w build Board: LaserBoard Firmware: Smoothie So I’m doing some of the last wiring needed and moving shortly to the testing phase. My issue is wiring the LPSU to the LaserBoard. I’m using the same type of lpsu as my current red black ruida machine. Here are pictures of the power supply. I also added one more to show how the ruida machine is wired as reference. Some assistance would be appreciated. [image] [image] [image]

You should connect L/ TL on the LPSU to the Laser Fire to the board and G to Laser Gnd on the LPSU.

Alternate PWM out on the LaserBoard is a backup for certain situations but not used in the way described above.

I wanted to get a “Hooking the LaserBoard to other LPSU’s article written up for you and this question, but was not able to do so yet”
