What I’d Do Differently After 5 Years of DIY CNC Router Use RCNC X2 Ep. 17

In RCNC X2 Router 17, I look back after several years of real-world use and answer the big questions: What would I do differently? What failed? And what maintenance does a DIY CNC router really need? In this video I: Raise the gantry to fix limited Z-clearance Service and clean the HIWIN linear rails and bearing blocks Repair and upgrade the zero-backlash rack & pinion system Replace worn belts with stronger 8M motion belts Discuss belt tensioning mistakes and failure points Share lessons learned about cable chains, motion-rated cables, and connector issues I also explain why I use dry PTFE lubricant instead of grease in a dusty woodworking environment, and what actually holds up after years of cutting. If you're building or running a DIY CNC router, using rack and pinion drives, or designing a large-format gantry machine, this video shares honest long-term feedback, maintenance tips, and real design mistakes to avoid. #CNCRouter #DIYCNC #RackAndPinion #CNCMaintenance #GantryCNC #LinearRails #WorkshopEngineering 00:00 Intro in the mistakes and maintenance. 01:15 How did the rack and pinion systems hold up? 03:22 Disassemble the CNC machine. 07:50 The biggest mistake in the design? 09:50 Fixing the mistake. 14:10 To grease or not to grease, that's the question... 19:10 Repair and maintain the rack and pinion system 25:10 The electrical problems i ran into.
