FluidTouch Installer

October 10, 2026

ESP-NOW Connection: Connect to FluidNC directly over ESP-NOW with no WiFi network needed (FluidNC v4.1.0 or later); pair from the machine editor
Wired Connections: UART through the Advance's UART0 header, or USB CDC through the display's USB-C jack to FluidNC's USB host port (USB CDC needs a FluidNC release newer than v4.1.1)
File Uploads: Choose FluidNC's SD card or flash and an existing folder; uploads over WiFi or wired connections show the transfer rate, can be cancelled, and keep the display awake
Axis Configuration: Turn X, Y and Z on or off per machine; X-only machines get a single Main tab with saved positions
Load This Machine at Startup: Skip the machine list and connect straight to a machine
Reconnect: Reconnect from the System Options popup without restarting
Advance v1.4 and v1.5: Supported with the same firmware as v1.3
3D Printed Case and Stand: Print-ready files for an Advance case with room for a large battery, plus a table stand
Fixes: Correct alarm messages, uploads with mDNS hostnames, a late HOLD popup and slow Files list on FluidNC v4, and more
Platform: Official pioarduino platform (Arduino 3.3.12, ESP-IDF 5.5.5), LovyanGFX 1.2.29
⚠️ Advance v1.2: Not tested; support may be dropped in a future release

April 24, 2026

Probe / Limit Switch Indicators: Real-time pin status — probe indicator on Control → Probe and the Status tab; per-axis limit-switch indicators on Control → Actions and the Status tab. Triggered indicators stay visible for 500ms so brief activations are easy to see

FluidNC Version on About Tab: Settings → About now displays the connected FluidNC controller's firmware version
M7 + M8 Coolant Display: Status tab now correctly shows both flood (M8) and mist (M7) coolant when active simultaneously
A-Axis is Per-Machine: A-axis enable/disable is now stored per machine instead of as a global setting, allowing mixed 3-axis and 4-axis configurations
Library Updates: LVGL 9.5.0, LovyanGFX 1.2.19, ArduinoJson 7.4.3
ESP32 Platform Branch: Switched to Arduino/IDF53_gcc15 after the previous upstream branch was removed/renamed
