BambuDry
macOS
BambuDry is a free, open-source macOS menu bar utility that keeps your Bambu printer's AMS units dry automatically. When humidity creeps above your target, the built-in heater turns on; when it drops back, the heater turns off. All control happens over LAN — no cloud account, no telemetry. MIT licensed.
// features
>Humidity-threshold automation
Set a target. When AMS humidity rises above it, BambuDry turns the heater on; when humidity drops back, the heater turns off. No manual intervention.
>Anti-cycling guards
Built-in cooldowns prevent the heater from rapidly toggling on and off when humidity hovers right at your target.
>Quiet menu bar app
SwiftUI menu bar utility — runs in the background and surfaces a small dropdown when you need it. No dock clutter.
>Multi-AMS support
Daily-driver tested with AMS 2 Pro and AMS HT units. Each AMS is monitored and controlled independently.
>LAN-only control
All printer communication happens over your local network. No cloud account, no telemetry, nothing leaves your network.
>Free and open source
