The default Mach3 installation only natively displays four axes (X, Y, Z, and A) on its primary run screens. To monitor and control 5th and 6th axes (B and C) effectively, you must install a custom 6-axis screen set. 1. Obtain the 6-Axis Screen Set Official Source : Visit the Artsoft/Mach3 Screenset Page to find 6-axis options. Common Files : Most downloads will be a .zip containing a .set (or .lset ) file and a folder of bitmaps/graphics. Recommended Sets : Standard 6-Axis Screen : A basic extension of the default 1024 set. Modern Sets : Sets like those from Physics Anonymous or the "2010 Screen Set" offer modernized layouts and integrated pendants. 2. Installation Steps Extract Files : Download and unzip the files to your desktop. Move the .set File : Copy the .set file into the main Mach3 installation directory, usually C:\Mach3 . Move Bitmaps : Copy the folder containing images (often named after the screen set) into C:\Mach3\Bitmaps . Load the Screen : Open Mach3. Go to View > Load Screens . Select your new .set file and click Open . 3. Configuration for 6-Axis Use Once the screen is loaded, you must ensure Mach3 is actually communicating with the extra axes: Enable Axes : Go to Config > Ports and Pins > Motor Outputs . Ensure the B and C axes are checked as "Enabled" and assigned the correct step/dir pins for your controller. Set Hotkeys : The 5th and 6th axes often require manual hotkey assignment for jogging: Go to Config > System Hotkeys . Assign unique keys for B++, B--, C++, and C--. Tip: Ensure these keys do not conflict with existing shortcuts, or jogging will fail. Visual Verification : Check the "Program Run" or "Diagnostics" tab. You should now see Digital Read Outs (DROs) for all six axes (X, Y, Z, A, B, C). 4. Troubleshooting Common Issues How To Install A 6 Axis Screen Set In Mach3
Mach3 6-axis screen set story is one of community-driven innovation. While the standard interface only displays four axes by default, the software itself has long supported up to six (X, Y, Z, A, B, and C). This gap led independent developers and hobbyists to create custom "screen sets" to unlock the full potential of complex CNC machines like 5-axis mills and robotic arms. The Evolution of the 6-Axis Interface The Original Limitation : Early Mach3 users found that while they could configure 6 motors in the "Motor Outputs" tab, the default visual interface (1024.set) hid the B and C axis data. Community Creators : Pioneers like Robot Factory and users like developed revised versions specifically to make these hidden axes accessible. Modern Refinements : Later sets, such as the Physics Anonymous (PA) Screen Set Mach3 2010 Screenset , shifted the focus from just adding axes to creating professional, "Windows-like" environments with cleaner layouts and automated probing features. Core Features of a 6-Axis Screen Set Full DRO Visibility : Unlike the default view, these sets place the Digital ReadOuts (DROs) for all six axes (X, Y, Z, A, B, and C) on the primary "Program Run" screen. Enhanced Tooling & Probing : Many custom sets include advanced macros for Auto Tool Zero , edge finding, and laser positioning offsets. Customization Tools : Developers used software like Klaus' MachScreen to build these interfaces, allowing users to modify buttons and hotkeys to suit specific machine needs. How to Implement a 6-Axis Setup Download & Extract : Screen sets are typically distributed as files bundled with a "Bitmaps" folder containing the interface graphics. Installation file into the main directory. Copy the contents of the graphics folder into C:\Mach3\Bitmaps : Within Mach3, navigate to View > Load Screens and select your new 6-axis file. Configuration : You must still configure Ports and Pins and assign System Hotkeys
A Mach3 6-axis screen set is a customized user interface (UI) designed to unlock the full potential of ArtSoft’s Mach3 CNC control software by providing direct access to all six available axes ( ). While the standard Mach3 installation typically defaults to a 3-axis or 4-axis interface, specialized screen sets allow operators of complex 5-axis or 6-axis machines to monitor positions and control motion more efficiently. Core Features of 6-Axis Screen Sets Modern 6-axis screen sets go beyond just adding extra Digital Readouts (DROs); they often include: Comprehensive Axis Monitoring : Displaying axis positions simultaneously on the main program run screen, which is essential for complex multi-axis milling. Advanced Probing Wizards : Integrated routines for auto tool zero , edge finding, and surface mapping, often with dedicated buttons for selections. Customizable Macros : Support for Visual Basic (VB) scripting to automate complex tasks, such as laser positioning offsets or synchronized multi-relay control. Modern Visual Aesthetics : Many sets, like those from Physics Anonymous or Etsy , offer 16:9 widescreen support and high-contrast designs that are easier to read than the legacy 1024x768 default. Jog Control Integration : Direct on-screen interfaces for jog pendants and hotkey assignments for precise manual movement of the 5th and 6th axes.

Mastering Multi-Axis Machining: The Ultimate Guide to the Mach3 6 Axis Screen Set In the world of DIY CNC machining, ArtSoft’s Mach3 remains a titan. While newer controllers like Mach4 and LinuxCNC have emerged, Mach3’s stability, massive user base, and plug-and-play nature keep it relevant. However, standard Mach3 installations are typically configured for 3-axis (X, Y, Z) or basic 4-axis (A) routing. What happens when you build a rotary lathe, a trunnion table, or a full 5-axis milling head? You run into a wall: the default screens don’t show the DROs (Digital Read Outs) for the extra axes. Enter the Mach3 6 Axis Screen Set . This specialized interface unlocks the full potential of complex CNC machines, allowing you to control X, Y, Z, A, B, and C axes simultaneously. This article is your complete resource. We will explore what a 6-axis screen set is, why you need it, how to install it, and how to troubleshoot common issues. mach3 6 axis screen set
Part 1: What is a Mach3 6 Axis Screen Set? In simple terms, a "Screen Set" in Mach3 is an XML configuration file paired with a set of bitmap images (.bmp) that define the user interface. The default screen (1024.set) only displays three or four axis DROs. A 6 Axis Screen Set is a modified UI that repositions the graphical elements to include:
6 Individual DROs: X, Y, Z, A, B, and C. 6 Individual LED indicators for homing and limits. Dedicated Jog controls (usually shifted or tabbed) for rotary axes. Custom macros (M-Codes) to control slave axes or rotary wrapping.
The Hardware Reality Before you download a screen set, you must understand the hardware limitation. Mach3, by itself, can theoretically control up to 6 axes. However, the parallel port (printer port) most hobbyists use only has 17 output pins—enough for 4 axes max (Step/Dir for 4 motors + outputs). To actually use 6 axes, you need: The default Mach3 installation only natively displays four
An external motion controller (Ethernet SmoothStepper, UC300, or PoKeys57CNC). A breakout board with 12+ outputs. Six stepper or servo drivers.
The screen set is just the "window." The motion controller is the "engine."
Part 2: Why Upgrade from the Standard 3-Axis Screen? Many users mistakenly believe they can just "type" a B-axis value into Mach3. Without a 6-axis screen set, you cannot see the position of your 5th or 6th axis without switching to a diagnostic tab. Key Benefits: Obtain the 6-Axis Screen Set Official Source :
Situational Awareness: When running a 5-axis milling job (e.g., impeller or turbine blade), you need to see B (tilt) and C (rotation) coordinates next to X,Y,Z. Scrolling through MDI or diagnostics introduces human error. Manual Jogging: Standard screens lack virtual buttons for the 5th and 6th axes. A proper 6-axis set includes on-screen jog arrows or radio buttons for A, B, and C. Homing & Limits: Complex machines require separate home switches for each rotary axis. The screen set allows you to visually confirm that A, B, and C are homed before starting a program. Macro Integration: Many 6-axis screen sets come pre-loaded with macros like "Rotary Unwrap" (turning a flat G-code X into rotary A) or "Axis Mapping" (swapping Y for B temporarily).
Part 3: Anatomy of a Quality 6-Axis Screen Set Not all screen sets are created equal. When searching forums or ArtSoft’s website, look for these features in a professional set (like the "2017 Screenset" or "Big Tex" 6-axis variants). 1. The DRO Block The top left of the screen should clearly show six lines:
