HF X2 shown below, with solid column and large table upgrades. Added a benchtopprecision.com belt drive, Igaging DROs, and spindle tach. Recently upgraded the spindle motor controller to a KBLC-19PM board with optional heatsink and custom enclosure. Preparing for Phase 2, CNC conversion. Was looking at the cncfusion hardware kit, but they've been unresponsive to email questions. Earlier X2 thread mentioned mbbilici.com kit, so looking into their hardware kit which looks promising. Copied this from their website "12mm diameter, 4mm pitch screw shaft and ball nut, (SF1204) C7 backlash (0.05mm)". Anyone tried their kits?
The electrical portion of the conversion seems to have an overwhelming variety of options, from individual components to various kits. Most of my mill work is aluminum with occasional steel projects, hobby use (not production), so speed isn't a priority. I'm intrigued by the ethernet smoothstepper capability as it would seem to broaden the computer configuration options. I've been looking at a 3 drive NEMA23 kit from cncrouterparts.com that uses the Leadshine MX3660 stepper motor system with choice of 420oz-in 3/8" shaft or 380oz-in 1/4" shaft stepper motors. They also offer the smoothstepper option. This look like a reasonable option? Which size motor would be best? Are there better kit options? Should I get double shaft motors to retain a manual control option? Suggestions very welcome.
