A full video of how to add a Z-axis rotary on a CNC 3018 machine.
Using a spindle pin for laser engraving.
- Use the Y motor pin for the rotary system.
- Add 10-50 ohm resistors on the spindle pin.
- Connect the laser to the spindle pin.
- Run a g-code using GRBL control software (check our download center for software >>>)
Keep in mind that there is no standalone PWM pin on the spindle pin, just use “+” and “-“.
Also, PWM has a high frequency on Woodpecker GRBL 0.9 board that is why some lasers might not work properly.
You need to reassemble a GRBL and setup ower PWM frequency and upload it on your Woodpecker GRBL 0.9 board or just use an Eleksmaker Mana board and connect it to your CNC 3018 router.
