Mini Laser Engraver (BE100)

This is my first laser engraver, i call it "BE100" for "Baby Engraver" with 100x108 for the bed size.

Technical informations:
Bed size: 100x108mm
Speed:0,01mm/s - 8mm/s maximum
Magnetic Bed: Yes
Led built-in: Yes
Laser: 1500mW (Blue-Purple Light 405nm)
Step motor: 28BYJ-48
Machine size: Wide=192mm, Deep= 162mm, Heigh= 188mm
Glasses Protection: Compatible with Blue-Purple Laser Light, between 200-540nm

The Negative point with my machine it's the engraving quality depending of the lead screws, Bended lead screw = wobble engraving

I made a second version with the same design chassis, I call it SE120, Quality and precision, large bed, limit switches, PWM/TTL laser module, bluetooth and a lot of new thing.
