Tired of click-through CAM classes - I want serious training on writing efficient G-code: Fanuc Macro B, probing logic, arc fitting/smoothing, and dialing look-ahead/jerk/tolerance to cut cycle time without wrecking finish. What courses or certs (online or on-site) actually leveled up your toolpaths and were worth paying for?
CNC Concepts (Mike Lynch) “Custom Macro B” was the one that leveled me up - solid exercises writing real probing/wear/parametric cycles and debugging with NCPlot. For toolpath optimization, FANUC’s AICC/G05.1 class plus a Renishaw Advanced Inspection Plus workshop made the biggest difference; tuning look‑ahead and filter tolerances there shaved about 15% for us without hurting finish. What control/series and options are you on (AICC level, HPCC, Renishaw macros)?
