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.
Step 1: BOM - materials/parts
###BOM - bill of materials###
Aluminium profiles 20x20 Type B
printed parts in PLA
-Allen screw M4x8
-Allen screw M4x20
-Allen screw M3x20
-M4 Threaded plate
Steel Rod 8mm diameter
2x - cm
1x - meter Timing Belt GT2
2x - Timing Pulley GT2 with 20 Teeth
4x - LM8UU linear bearings
1x - MDF Wood Baseplate 28x32 / 4mm thin
1x - Layer of thin Cork 30x30
1x - Arduino Uno R3
1x - GRBL-Shield
2x - Pololu a4988 Stepper Driver
1x - 12V / 3A power supply
2x - 12V Fan 4x4cm
2x - Nema 17 stepper motors / 36oz
1x - 250mw laser module
4x - Endstops
Various cable, different plugs...
Tools you need
1x - Allen Key M4
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 )
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.
Firmware for the Arduino UNO R3: Grbl 0.9
