Can you tell me how can i get the PWM on this card to control the laser power ?
and wich gecode command must i use ?
i have tried with the pins on the laser port with several M03 Sxxx
command but no changes on this pins !
thank you for your help,
now i control the laser with motor output.
Still have issue how to control the laser with the PWM, from the laser output on VIAxis, we have GRD, +5V and PWM ? , is the pwm with 12 V so we connect the laser on this pin or it's a 5V and we must use another circuit to drive a 12V ?
Also the pin are not clear on the diagram , wich one is GRD, +5V and PWM ?
im using EleksMaker® LA03-2500 445nm 2500mW Blue Laser Module With Heatsink For DIY Laser Engraver Machine from banggood,
Where must i connect the power ( PWM, or +12V ),
for the software , i'm using CNC USB, but i don't know how to control the laser for engraving with this soft.
