A Rust lib to send Gcode via UART to a 3D printer
A stream based GCode sender. The api is still in progress and subject to change.
Quick start Code:
use gcode_serial::gcode_serial::GcodeSerial;
use gcode_serial::models::action::{Action, Command, PrinterStatus, TelemetryData};
use gcode_serial::models::serial_connector::SerialConnector;
use tokio::sync::broadcast;
use tokio::runtime::Runtime;
fn main() {
// initialize Tokio runtime
let t = Runtime::new().unwrap();
let filename = "test.gcode";
t.block_on(async move {
let (tx, _) = broadcast::channel(32);
let t = tx.clone();
tokio::spawn(async move {
// create printer object
let mut gs = GcodeSerial::new(t);
// start printer service
gs.start(SerialConnector::Auto).await;
});
// send print start command
tx.send(Action::Command(Command::StartPrint(filename)));
let mut rx = tx.subscribe();
// monitor for receiving actions
loop {
if let Ok(v) = rx.recv().await {
match v {
Action::Telemetry(t) => {
match t {
TelemetryData::Temps(v) => {
println!("Extruder temp: {}; Bed temp: {}", v.ex_temp, v.bed_temp);
}
TelemetryData::Progress(x) => {
println!("Number of commands left in que: {}", x);
}
TelemetryData::TargetExtruderTemp(t) => {
println!("Target Extruder Temp change: {}", t);
}
TelemetryData::TargetBedTemp(t) => {
println!("Target Extruder Temp change: {}", t);
}
TelemetryData::TotalCommandCount(n) => {
println!("Number of total commands to send: {}", n);
}
TelemetryData::ActiveFile(f) => {
println!("Current file changed: {}", f.unwrap().name);
}
_ => {}
}
}
Action::StateChange(_) => {}
Action::PrinterAction(_) => {}
Action::Command(_) => {}
}
}
}
})
}
Usage
GcodeSerial object
At first you need to create an instance of GcodeSerial
for each printer you want to connect with
let mut gs = GcodeSerial::new(t)
where t is a broadcast channel needed to cummunicate with the lib.
Afterwards you can connect to the printer with gs.start(SerialConnector::Auto).await;
.
You might wanna call this in a seperate (soft)-thread because this call is blocking.
SerialConnector
You can choose if the serial port should be found automatically with SerialConnector::Auto
or manually with
SerialConnector::Manual("/dev/ttyUSB0", 115_200)
Receiving/Sending data from/to the printer
Attach to the broadcast stream and receive with the Enum the data you need. See example above.
Enum Field | Function | Example | Trigger |
---|---|---|---|
Action::Telemetry(t) | receive telemetry | temperature, progress, target temps, fan speed | value change |
Action::StateChange(t) | printer state change | Disconnected,Active,Idle,Errored, | value change |
Action::PrinterAction(t) | printer sent action cmd | cancel/pause/resume print | printer |
Action::Command(t) | send actions to the lib | start/cancel print, Set Temperatures | lib user |
