I will try to show you how to setup your CNC using PlanetCNC software. I will use my router machine as an example but you can do it similar way on all machine types. I use metric (millimeter) units but everything is same with imperial (inches) units except numbers are different (1mm is apporximately 0.03937in). […]

This is a short tutorial on how to correctly set Steps Per Unit values for your CNC machine. Steps per unit value (in further text as SPU) defines how many steps will stepper motor have to make in order to move the axis for distance of one unit. Units can be in millimeters or in […]
In tutorial “How to setup CNC machine using PlanetCNC Software and controller” was described how to use limit switches and software settings, so that our machine will be properly calibrated and set, therefore ready for everyday use, giving us correct and satisfying results. Please read this tutorial before continuing: How to setup CNC machine using PlanetCNC Software and […]
In ‘Machining your first work piece’ tutorial we described how to set Current XYZ offsets. – Offset – Current XY gives us relative coordinates. We can set Offset XY position coordinates anywhere on the machines table. This way we can adjust our imported program (G-code) to our table size and therefore set position that is […]
Difference between Fixed Tool sensor and Movable sensor: Fixed Tool Sensor: Used for measuring ‘Tool Offset’. Gives us position of the tool tip in absolute coordinates. Always at fixed position. Movable Sensor: For setting ‘Offset Current Z’ at the top surface of work material. Gives us relative coordinates. You can move it around the table, […]
Automatic tool change – ATC tutorial with PlanetCNC software and controller This tutorial will guide you through ATC hardware equipment installation, software settings configuration and final use of ATC with PlanetCNC software and PlanetCNC motion controller. We will start by installing ATC hardware equipment on our machine and later on continue with software settings configuration. […]
USING “WARP” FEATURE IN CNC USB CONTROLLER SOFTWARE ‘Warp’ feature is used when applying generated toolpath over bended, curved or uneven surfaces. This feature comes in great help to users that mill their own PCB’s. Since the PCB milling procedure itself is very delicate and precise (distance between two pads can be only xx mils), […]
MILLING PCB’S WITH CNC USB CONTROLLERS This tutorial is intended to help you with production of one-sided PCBs with your CNC machine. Before any work is done with machine you must be sure that the ‘Gerber’ files you intend to import in CNC USB controller software are correct and are generated with correct parameters. Some […]
MILLING DOUBLE SIDED PCB’S WITH CNC USB CONTROLLERS This tutorial will help you with production of double-sided PCB’s with your CNC machine. Before you start, please be sure that machine is properly set-up and calibrated. Gerber and drill files should be generated with correct parameters. Since tutorial for single sided PCB’s already describes the gerber […]
HOW TO SELECT STEPPER MOTOR AND DRIVER? Here are some documents I found on internet: Stepper motor and driver selection Drive circuit basics Step motor basics Torque converter
HOW TO CONNECT MOTOR DRIVER WITH OPTOISOLATED INPUTS? There are two possible connections: 1. Common cathode 2. Common anode
HOW TO CONNECT PROBOTIX MOTOR DRIVER WITH 10 PIN CABLE? It is easy to create 10pin cable for Probotix driver – just “cross” two wires to other side.
