I designed and built this custom-made CNC router using high-grade 1/4-inch steel plate cut precisely by laser technology, along with top-quality electronic components sourced directly from Chinese manufacturers, rugged bearing blocks also originating from China, and durable 1/2"-13 threaded rods to power the leadscrews. It achieves remarkable speeds of up to 20 inches per minute during rapid operation and exhibits exceptional rigidity when engaged in milling tasks involving aluminum - in fact, I successfully utilize this machine to precision-cut intricate molds. This CNC project boasted a total cost, including the upgraded high-performance 400-watt spindle, amounting to approximately $600. The depicted model shows an off-the-shelf harbor freight 2-horsepower router, which is actually an incredibly potent and versatile tool; I possess every available size, ranging from 0.125 inches up to 0.5 inches. However, this massive machine suffers from significant drawbacks, namely excessive bulkiness and an unpleasantly loud operational profile, even when the variable speed dimmer switch is engaged. In contrast, my initial attempts involved utilizing a compact yet reliable dremel for precision cutting operations targeting softer materials such as foam; it proves itself well-suited for handling this task with finesse. Nonetheless, attempting to employ the dremel for wood-cutting tasks proved extremely challenging, often leading to motor stall conditions during light endmill usage. My verdict remains clear: under no circumstances would I recommend fashioning a DIY CNC router around a humble dremel; it simply lacks the power and capacity required to tackle more substantial materials. On another note, I created several critical 3D-printed components specifically designed to secure nuts and bearings within place - a thoughtful endeavor which not only provided valuable assistance but also allowed these custom-made parts to prove remarkably resilient in withstanding heavy usage. The outcome was genuinely surprising, with these initial 3D-printed iterations emerging stronger than I had initially envisioned. I'm led to question whether it will become unnecessary for me to subsequently manufacture these component parts using machine tools; such was the outstanding reliability of my ABS prototype's structural integrity.
