Yet Another CNC Machine, or YACM for short, is a fascinating project that consists of 2020 aluminum extrusions, SFU1204 ball bearings for each axis, and approximately 16-20 easy-to-print parts. The machine has a very small footprint of 315mm x 310mm. The work size of the machine is 160mm (X) x 100mm (Y) x 35mm (Z), making it ideal for standard euro PCB sizes. I printed all the parts in PETG, including the spindle mount and Z-Top & Z-Bottom with 100% infill, resulting in a rock-solid structure that feels unbreakable. The Bill of Materials (BOM) for this project is available on Thingiverse. The extrusions and linear rails are sourced from Motedis, while everything else comes from AliExpress. Here's the list of components used: Extrusions: - Base left & right: 2x 275mm 40x20 - Base front & rear: 2x 270mm 40x20 - Base center: 2x 220mm 40x20 - Portal left & right: 2x 330mm 40x20 - Portal top: 1x 310mm 40x20 - Portal center: 2x 270mm 20x20 - Work bench: 2x 180mm 60x20 - Z-Axis frame: 1x 160mm 60x20 Rolled ball screw - end machined & nut: - SFU1204 300mm (X) - SFU1204 250mm (Y) - SFU1204 150mm (Z) Linear rails: - 10mm x 310mm (X) - 10mm x 260mm (Y) - 8mm x 170mm (Z) Linear rail shaft support: - 8x SK10 Linear bearings: - 8x LM10UU 29mm (X&Y) - 2x LM8LUU 45mm (Z) Bearings: - 6x 6900zz 10x22x6 - 3x F608ZZ 8x22x7 Stepper motors & couplings: - 3x NEMA 17 2,5A 4800g/cm - 3x 5x8 D20 L30 Brackets, screws, washers, nuts, nyloc nuts and 2020 hammer nuts: - 2028 brackets 2x 20pcs - M5 slot nuts 100pcs - M5x10 screws 100pcs - M2,5x14mm and nuts to attach the z-limit-switch to the holder - M3x25mm, washers and nyloc nuts to attach the z-limit-switch-holder to the z-rod - M5x16mm to attach the Z-Top to the Z-Axis Frame - M5x20mm to attach the Z-Bottom to the Z-Axis Frame - M3x14mm countersunk screw to clamp the LM8LUU in the spindle mount - M3x20mm, washers and nyloc nuts to clamp 4x LM10UU in the x-carriage - M4x20mm, washers and nut to clamp the spindle in the spindle mount - M2,5x20mm countersunk screw for the BK10 - M4x25mm, washers and nut to fix the ball screw nut in the holder Additional stuff: - Yaseem X-carriage cable chain: https://www.thingiverse.com/thing:2780527 You can watch a video of this project on YouTube by searching for "Yaseem CNC Machine".
