In this video from my DIY Plasma CNC build series, I explain why I chose a rack and pinion drive system — and not ACME threads, belts and timing pulleys, or ballscrews. I go in-depth on the technical and practical reasons behind the decision, all from the perspective of a plasma cutting machine that can be converted in a CNC Router. Most importantly, I share and walk through a spreadsheet tool I built to calculate the correct rack & pinion setup. It includes motor specs, gear ratios, speeds and the complete force transmission. Perfect if you're building your own CNC!
