ADDITIONS: For Anycubic Mega Pro, a command to turn on the G6 S1 burning laser, a command to turn off the G6 S0 laser. The PWM is 100% full after executing this command. It seems impossible to make another PWM to the laser through the wires of the hot-end heater. This is a specific command added by the developers for this particular printer. There is such a command in the Marlin G-code specification, but it is not intended for this at all. It turns out that to start cutting along the trajectory on the Anycubic Mega Pro printer, no modifications are required. This video might be useful for anyone looking to connect a laser to some other printer, or to connect a more powerful laser to the Mega Pro. Swapping the pins in the green connector almost makes no sense, only if you want to control the PWM of the laser via G-code from 0 to 75%. A more powerful three-wire laser can be connected to Mega Pro both to the hot-end cooler and to the hot-end heater, according to the proposed scheme with a mosfet key.
This video should cover most of the issues related to laser upgrading 3D printers.
It will talk about how to teach the Anycubic Mega Pro 3D printer to cut parts with a laser along a trajectory. The information contained in this video will also be useful for those who want to install a laser on some other 3D printer.
I will consider the electrical circuits for connecting the laser, and the problems that may arise.
I will tell you how to connect a more powerful laser to the Anycubic Mega Pro printer using three wires.
I will show the oscillograms of the PWM signals, the Anycubic Mega Pro electrical wiring diagram.
