I made a simple carriage to use Ender 3 Pro as a cnc / engraving tool. I used RS775 DC motor and 19V 4A power supply. RS775 is very successful in acrylic engraving and drilling. I haven't tried making PCBs yet, but I think it will be successful too. I will try as soon as possible.

UPDATE (03.07.2021): @MatessakCZE made a great contribution and made a holder (carriage) remix for ProperPrinting's quick tool change design. You can download the remix by clicking here and you can do a quick change instead of removing and putting all the screws back in each time.
