[r]evo Slicer and Revo OS – connecting to a Revon printer and what passes between them

In most 3D printers the slicer and the machine know little about each other: the slicer produces a file, the printer blindly executes it. Revon printers with Revo OS are different – [r]evo Slicer and the machine exchange information, so operators make fewer mistakes and fewer prints end up in the bin. USB sticks with G-code are a thing of the past: you send the file over the network with one button.

Connecting [r]evo Slicer to the printer

1. The computer and the printer must be on the same company network.
2. In [r]evo Slicer click the connection icon next to the printer. Revons on the network appear in the list automatically – choose yours or enter the address (revon.local or the IP from the machine screen, next to the clock).
3. Enter the manager’s login and PIN (first start). The slicer fetches the access key from the machine itself.
4. Slice the model and click Print. The file goes to the machine, and the Device tab shows Revo Panel with the camera and print progress.

What passes from the slicer to the machine

Nozzle

The start G-code of the Revon profile begins with REVO_CHECK_NOZZLE. The machine compares the nozzle diameter and type in the file with the installed nozzle and stops on a mismatch. This protects against the most common production mistake: a file sliced for 0.6 mm run on a 0.4 mm nozzle – many hours of printing and wasted filament.

Material and temperatures

PRINT_START receives the nozzle and bed temperatures and the filament type. Revo OS adapts the machine preparation to them and prompts the operator, e.g. to open the chamber door for PLA, which does not like high ambient temperatures.

Thumbnail, time and filament use

The screen and Revo Panel show a thumbnail of the model, the estimated time and material use. Revo OS compares them with what is left on the spool and warns before the start if filament may run out.

Print cost

Filament use from the file and the measured power consumption give an estimated cost of every print – useful for quotes and job accounting.

Why only two slicers

Revon printers accept prints only from [r]evo Slicer and – optionally – from Orca Slicer with the Revon profiles. Files from other slicers (PrusaSlicer, SuperSlicer, Cura) are rejected right after upload, and the operator sees why. Without our start G-code the machine gets no information about the nozzle and material, so it cannot protect the print.

Why an access key

Revo OS does not accept commands from the network without authorisation – nobody on the company network can send a file or stop a print without the key. Only the manager and service see the key. If it leaks or an employee leaves, service generates a new one and you connect the slicer again.

Optionally: Orca Slicer

1. Revon profiles: in [r]evo Slicer File → Export → Export Preset Bundle, in Orca Slicer File → Import → Import Configs.
2. Open Revo Panel (the machine address in a browser), log in as manager and go to Service → SHOW CONNECT COMMANDS.
3. Copy the command for Windows (PowerShell) or macOS (Terminal) and run it on the computer – it adds the printer together with the key.
4. Restart Orca Slicer and select the printer “My Revon … @ address”.

Not working? Check in order

• Same network – a guest Wi-Fi network usually cannot see company devices.
• The address changed – after a router restart the machine may have a new address. Check it on the screen and connect the slicer again. Best ask IT for a fixed address for the printer.
• File rejected – check that you selected the printer and filament from the Revon profiles.
• Slow upload – large files over weak Wi-Fi can stall; a LAN cable solves it.
