I start to plan the ZelosLaser Engraver with the goal of a well-built, Open Soft and Hardware Machine.The ZelosLaser Engraver is affordable, with a compact design and the perfect entry for the Daily Hobbyist.
It is easy to build. even for the non Hobbyist.

Tools you need

1x - Allen Key M4
1x - pliers

1x - Metalsaw when the steel rods or aluminum profiles are not even cut when you buy it.

1x - Jigsaw when the base plate has not been cut when buying

some wood glue (to glue a thin layer of cork on the bottom plate )

Step 3: BUILD IT

Begin with the aluminum profiles. screwed together like in the Images.

Do not forget to push enogh M4 threaded plates into the V-slot of the profile.

Step 4: Electronics/wiring

Step 5: SOFTWARE
