Follow every print, on every printer.

3D preview that follows the print

The part on the printer bed, drawn from the G-code, grows layer by layer. A 2D view of each layer is there too.

Time left and finish time

Each printer gets its own card with a 3D thumbnail, progress, current layer and estimated finish.

Everything stays on your PC

No account and no cloud: SonoPrint talks to your printers on your home network and works offline too.

And also

  • G-code terminal with history
  • USB, network, Bambu and Klipper cameras
  • Safe pause and resume
  • Emergency stop
  • Windows notifications when a print ends
  • Print history with stats

How it works

  1. Add your printers

    Press Aggiungi stampante (Add printer): the ones on your home network show up on their own. For a USB printer, pick the port and SonoPrint finds the baud rate.

  2. Upload your files

    .gcode files and .gcode.3mf projects from Bambu Studio and OrcaSlicer, in one library shared by every printer. Just drag them in.

Works with the printers you have.

Over USB or on your network. Network printers keep printing even if you close SonoPrint.

USB

Marlin, Prusa, RepRapFirmware and derivatives

What you need

A USB cable. SonoPrint lists the COM ports, flags the ones that look like printers (CH340, FTDI, STM32) and finds the baud rate on its own.

What you can do

  • G-code streaming with checksums and automatic resend of corrupted lines
  • Axis moves, extrusion, fan, speed and flow
  • G-code terminal
  • Firmware updates

Good to know: The print is driven by the PC: if you close SonoPrint or the PC goes to sleep, it stops. That is why SonoPrint blocks sleep during USB prints.

Firmware and software, always up to date.

The Aggiornamenti (Updates) page gathers SonoPrint and every printer. Aggiorna tutto (Update all) goes one step at a time and skips printers that are printing.

SonoPrint writes it

  • USB, 8-bit boards

    ATmega2560, 1284P, 328P with bootloader

    Writes the .hex file over USB and reads every page back to verify it.

  • USB, 32-bit boards

    Creality 4.2.x, BTT SKR, MKS

    Copies the .bin to the SD card with the right file name. Put the card back in the printer and power it on.

The printer updates itself

  • Bambu Lab

    Copies the official package to the microSD card, then you start it from the printer screen under Settings > Firmware.

  • Klipper

    Moonraker's update manager: Klipper, Moonraker, Mainsail or Fluidd and the system, one at a time or all together.

  • OctoPrint

    Updates OctoPrint and its plugins, with an administrator key.

  • PrusaLink

    Shows the installed version and the latest one from Prusa. The update itself is done with a USB stick.

Before flashing firmware over USB

Save your settings with M503 in the terminal and check that the file is built for your board. SonoPrint never touches the bootloader, so if something goes wrong you can try again.

  2. Run it

    Pick a folder and install. If “Windows protected your PC” appears, click More info, then Run anyway: the app is not code-signed.

  3. Add a printer

    Open SonoPrint and press Aggiungi stampante (Add printer). Printers on your network are listed at the top.

From then on it updates itself: it checks at startup and every 6 hours, downloads in the background and offers Riavvia e aggiorna (Restart and update). A USB print in progress is never interrupted.
