<p><strong>BLUE-CNC (nema23) Version 1.0</strong></p> https://youtu.be/gL4MpC-D_eI Like many enthusiasts, I was eager to build a 3D printed CNC machine. In fact, I opted for the TopsCNC, which can be found on Thingiverse at https://www.thingiverse.com/thing:3813481. However, after starting construction of the TopsCNC, I realized that Nema 17 motors might not provide enough power. So, I decided to adapt the design to use Nema 23 motors instead. By the time I had modified 60% of the design, I knew I needed to start over from scratch. The unique feature of this DIY CNC machine is its ability to mount Nema 23 motors, which increases the cost. To save some budget, I opted for GT2 belts instead of screws throughout the system. For electronics, I used an Arduino UNO and a CNC Shield with TB6560 drivers. I built my CNC machine using 1000mm aluminum profiles, giving me a working area of 850mmx850mm. Actual Budget To build this CNC machine, I needed 1.8 kg of 3D filament, which cost €45 in Petg and €36 in PLA. In total, the necessary materials came out to be €330, including the milling machine. The estimated economic cost would be around €370. Here's a list of the necessary components: Screws: * 22u - Wooden screws (depending on the base used) * 22u - M5x50 * 12u - M4 x25 * 8u - M6x30 * 8u - M4x10 * 30u - M4x15 * 8u - M4x30 * 2u - M4x25 * 24u - M6 nuts (wheel spacers) * 6u - M5x35 * 32u - Nut for slot 5 type-I [M4] Components: * 4u - V-Slot 20x40mm- 1000mm * 1u - Closed GT2 Belt 280mm 140 teeth * 3u - GT2 20 teeth pulley 8mm axle * 2u - SC8UU linear bearings * 1u - RPTS trapezoidal threaded spindle right TR 8x1,5 * 1u - Trapezoidal spindle nut - flange EBFM 8x1,5 * 8u - Bearings 608 2RS 8x22x7mm * 1u - Precision steel shaft Ø8mm 1000mm * 2u - Precision steel shaft Ø8mm 180mm * 1u - Closed GT2 Belt 200 mm 100 teeth * 4u - GT2 Pulley 40 teeth 8mm Shaft 2 Units * 1u - 3D Timing Belt, GT2-6mm 10M * 3u - 2GT timing belt aluminum gear clamp mounting block * 1u - CNC Shield V3.0 + R3 Board * 1u - 10pcs 3D Printer V-slot Pulleys POM Plastic V Wheel V-slot Pulley * 1u - KATSU 101750 Electric * 1u - 4 pcs TB6560 stepper motor controller + interface board + 4 pcs Nema23 270 Oz-in motor + power supply
