DIY Mini CNC Engraving Machine

thingiverse

Hello guys, I've built a mini Engraving CNC machine using the 28BYJ-48 Stepper motor, Arduino Uno board, GRBL CNC shield, and rotary tool as spindle. This is my prototype project, and I wanted to see if it's possible to make a mini engraver without breaking the bank. Unfortunately, the machine isn't as accurate as I had hoped because of using a timing belt on both X and Y axes. The belts cause some steps to be skipped, but everything else works perfectly fine. Next time, I'll use lead screws instead of timing belts. https://youtu.be/7fBV-XRt438 Arduino: http://amzn.to/2nNepm5 Stepper driver: http://amzn.to/2GYxk5o GRBL CNC Board: http://amzn.to/2BgPU8k 28BYJ-48 Stepper motor: http://amzn.to/2GRpPgh Rotary Tools: http://amzn.to/2E7VBYN Software download links: GRBL: https://github.com/grbl/grbl F engrave: http://www.scorchworks.com/Fengrave/fengrave.html 3D Files: https://www.thingiverse.com/thing:2785062 Visit for more projects at electricdiylab.com
