3 × 40mm Nema17 Stepper Motor (42BYGH) X/Y/Z stepper motors.
1 × GRBL CNC Control Board Some sort of GRBL based control board. I have used this one: https://www.aliexpress.com/item/32713561151.html?spm=a2g0s.9042311.0.0.27424c4dCcgkWk
1 × RS-775 Motor Actual spindle for milling. Any spindle will do, but the Z-axis would need redesigning for anything other than this motor.
1 × ER11 Chuck Mounts to the motor, and clamps milling bits. You can get this and the RS-775 motor as a set.
8 × LMK10UU Linear Bearing These are used on the X and Y axes, to guide the assemblies along the linear rails.
2 × KFL08 Bearing Block Bearings for the X and Y axes ends (Mounted opposite the stepper motor)
3 × T8 2mm Pitch, 2mm Lead Brass Nut Nuts for the axes lead screws.
22 × 2020 Extrusion Right Angle Brackets As described in the "Details" section. These brackets should go at every right angle of the extrusions, giving the machine a bit of rigidity.
12 × M2 x 8mm Screw For mounting limit switches to plastic.
50 × M5 x 10mm Bolt
80 × M5 T Block Nut For aluminium extrusions. I ordered some from aliexpress with a 20S spec, but I am not sure how standard this is.
2 × 280mm 2020 Aluminium Extrusion, Drilled & Landed Holes drilled and landed, as described in pcb_mill_metal.jpg in the project douments.
2 × 10mm x 320mm Linear Rod X axis rods.
1 × 320mm 2020 Aluminium Extrusion, Drilled & Landed Holes drilled and landed, as described in pcb_mill_metal.jpg in the project douments. This is the top of the gantry.
2 × 320mm 2020 Aluminium Extrusion, Tapped Both ends M5 tapped, as described in pcb_mill_metal.jpg in the project douments.
2 × 280mm 2020 Aluminium Extrusion, Tapped One end tapped M5, as described in pcb_mill_metal.jpg in the project douments.
