Hi Folks,
I just bought a 5W module with an outboard controller (see attached) to upgrade my cutter. It needs a 5v TTL signal in.
I've been away from my laser setup for awhile, and seem to have forgotten almost everything I learned about configuring the hardware, so I'm back at the bottom of the learning curve again. I have a Mana 5.2 board, running a 3-axis setup with a 2.5W non-TTL module. The laser is currently connected to the motor output, and PWM seems to be working to control the intensity.
I've been reading through the threads here, and I think I have a handle on what I need to do, but before going ahead and letting the magic smoke out, I thought I'd check and get some confirmation.
So as I understand it from reading the thread here, I'm going to:
i) power the laser with an independent power supply into the 12v in on the board.
ii) connect the Analog - input to the Servo ground on the Mana
iii) connect the Analog + to the Servo PWM on the Mana.
iv) set the selector on the board to TTL.
v) cross fingers and hope!
Sound about right? TIA for your advice!
