Learn how to tune stepper motors in Mach3: calculate and verify steps per unit, find the maximum safe velocity and acceleration for each axis, and set driver current correctly.
A step-by-step Mach3 setup guide covering installation, motion controller plugins, ports and pins, limit switches, homing, E-stop, and spindle control.
CNC machining materials compared: aluminum, steel, stainless steel, brass, titanium, and engineering plastics, with strength, machinability, and cost, plus a step-by-step way to choose.
CNC machining tolerances explained: standard values, ISO 2768 general tolerance classes, H7 hole and shaft fits, why tight tolerances raise cost, and how machined parts are measured.
Small batch CNC machining from 10 to a few hundred parts: how setup cost shapes cost per part, how to keep every part consistent, and when to choose CNC or 3D printing.
Prototype machining explained: when a CNC machined prototype beats a 3D print, what sets cost and lead time for a one-off part, and design tips that get prototypes made faster.
CNC surface finish explained: as-machined Ra values, when to specify a smoother finish, deburring and edge breaks, and finishing options such as bead blasting, anodizing, and powder coating.
A step-by-step guide to adding sensors to machines you already own, from choosing what to measure to wiring, noise, data, and commissioning.
Alarm management for monitored machines: alert types, thresholds with deadband and delay, alarm-rate targets from ISA-18.2, and rules that avoid alarm fatigue.
A machine monitoring system shows when each machine runs, stops, and why. What to track, OEE and utilization, dashboards that work, and how to start.
