This webapp lets you stream G-Code (created by Cura, Orca Slicer, etc.) to your websocket-enabled printer(s).
Known compatible printers:
The built-in webapp even with "high speed" enabled can only upload your file at ~10-20kB/s. The upload often fails, and when it doesn't it usually takes half as long as the estimated print time! 🤦
Because this project streams the G-Code, prints start instantly. (You don't even need an SD card.)
Why not stream G-Code to port 23 using a tool like gcode-cli?
The printer's handling of telnet sessions is unreliable (even with good WiFi). I've never seen it not fail, even with short prints.
Yes it is! Fortunately my experience is if it's close enough to your router or a repeater (like in the same room), it's good enough.
No, neither ever leaves your network. The whole app is static HTML + Javascript, hosted by Github, and collects no data.
Because it's streaming G-Code from your browser, you have to keep your computer on and the site open for the duration of the print.
