- I need help to connect the laser to my lowrider on the rambo 1.4a board (https://www.aliexpress.com/item/32958037528.html?spm=a2g0s.90423188.8.131.52424c4dO6m4K7). I found several topics about lasers and a howto on the site, but all this concerns old rambo boards and lasers with a separate control board that only need 12V power. Maybe I do not understand something, but is there a clear instruction for connecting the laser pwm to the rambo 1.4a board? I will add a photo of my laser and my board.
- For not to multiply topics: I have almost finished the work necessary for the airbrush module for my lowrider. For this job, I need to connect a servo machine to control the opening of the air supply valve. I found articles about connecting servo to the old version of rambo (https://3dprintboard.com/showthread.php?9335-Rambo-Servo-Setup-for-Auto-Bed-Leveling-for-Noobs) but in my version these contacts are located otherwise. I do not want to burn something, someone will help with this issue as well?
