Mach3 Screenset Editor

Mach3 screenset editors allow you to customize the software's user interface by adding, removing, or repositioning controls like buttons, DROs (Digital Read Outs), and LEDs. The most common tools used for this are MachScreen and the older Screen4. Essential Tools for Editing

Key concepts

• Screensets: Collections of screens (pages) representing different machine modes or tasks (e.g., jog, auto, MDI, settings).
• Widgets: Individual UI elements (buttons, LEDs, numeric displays, text labels, gcode DROs, MPG input, tool offset displays, spindle controls).
• Events & Scripts: Buttons and controls can be linked to Mach3 macros or VBScript routines to run machine functions.
• Layers & Grouping: Elements can be organized and aligned for consistent layout; Z-order determines which items appear on top.
• Resolution & Scaling: Screensets are resolution-dependent; design for the target monitor size and scale carefully for legibility on touchscreens.

Common Commands:

• Backup your C:\Mach3\Bitmaps\ folder right now.
• Download a community screenset to reverse-engineer.
• Print out a cheat sheet of OEM codes (DoOEMButton commands) and tape it to your monitor.

Mach3 is incredibly powerful, but its default interface was designed as a "one-size-fits-all" solution. A plasma cutter operator needs different buttons than a wood router user. A lathe operator doesn’t care about spindle load meters, while a high-speed engraver desperately needs a visual feed-rate override slider. mach3 screenset editor

The Good: Absolute Control

Unlocking the Power of the Mach3 Screenset Editor

If you’ve ever used Mach3 for CNC control, you know the default interface works — but it may not work for you. That’s where the Mach3 Screenset Editor comes in. This built-in tool lets you customize the look, layout, and behavior of the Mach3 user interface to match your workflow, machine, or even your personal taste.
