Hello,

Please, please help me.
I need help from cnc drive.
Im figthing and testing a long time to get my laser to work.
I chosed as laserpin pin 17 on Port 1 in the Uccnc software.
I have the Uc-300eth with a conected triplebeast to port2.
To wich Port and pin i have to connect my signal and groundline from the laser to comand him by M3 M10 Qxxx comands?
My knowledge is very bad in electronics, so i realy need help to understand how it works.
Which settings i have to do in uccnc and do i need an relay?
Maybe somebody from the cnc drive members can sent me marked pictures how to set up and how to wire.
I have tried to find out in previous Chats but i cant understand how to apply the 5volts to the pwm pin of my laser and also to the enable pin..

Im very thankful for help!
