More Info
The new jog controls can be accessed from the MAIN screen. The new analog jog controls function like an on-screen game controller with full proportional speed control for travel in any direction with precise speed control. The new pendant jog controls simulate an on-screen pendant with adjustable step distances.
Software Version 1.1.1
[2025-10-21]

More Info
The new spindle warmup widget can be accessed from the Spindle tab on the MAIN screen. Click on the affectionately-named "bacon" button to access the warmup controls.
The widget provides three different warmup stages, each with their own spindle speeds and timers.
The Raspberry Pi 5 image below can be used to restore your system to factory defaults.
Flashing the SD Image
Generally, flashing the SD card image is only required in extreme circumstances to restore the operating system and software to factory defaults.
All files and settings on the target SD card will be lost.
Refer to the RTS-X documentation for instructions on how to flash an SD card image.
