Prusa Remote Display - desktop status screen for Prusa CORE One

Prusa Remote Display - desktop status screen for Prusa CORE One

Your print, at a glance.

A small screen for your desk that shows what your printer is doing, how far the print has progressed and how much time is left. No need to reach for your phone or walk over to the printer.

It reads status directly from your printer over home Wi-Fi using PrusaLink. There is no cloud account, subscription or separate server. It monitors one printer and never sends printer-control commands. When online, it also checks GitHub roughly once a day for firmware updates; it installs nothing unless you choose to update. Normal monitoring stays on your local network.

Get the parts

Use the Waveshare ESP32-S3-LCD-2.8, non-touch board. On the official Waveshare product page, select Without Touch Function. You can buy it from any seller, as long as it is the non-touch version. The product-page URL says “touch”; select Without Touch Function. The touch model and other ESP32 boards are not interchangeable.

You also need access to a 3D printer, fine pliers, 1.5 mm and 2 mm Allen keys, a computer for installation and 2.4 GHz Wi-Fi that lets the display reach the printer. Tested only with Prusa CORE One and local PrusaLink access; MK4S and MINI compatibility has not been established. No soldering, threaded inserts or glue are required for the case assembly.

The main purchase is just the Waveshare board, at about US$20–26. If you buy the other materials new too (filament, a cable, a USB charger and screws), budget about US$40–50 in total for one build, before shipping and tax. See the parts and cost breakdown.

Choose the print files

• PrusaSlicer: use display-enclosure.3mf. It contains the four groups in their print orientations, with no printer, print, filament or support settings.

• Other slicers: use shell.stl, rear-cover.stl, carrier.stl and cassette.stl.

• Print one of each group and keep the supplied orientation.

• The cassette contains five bodies that print together. Keep all five together, including the button and three temporary pads. The pads are model geometry, not slicer-generated supports.

• There are no printed nut keepers; the two square M3 nuts remain in the build.

• STEP files use shared assembly coordinates and are not print-orientation guides.

Editable design sources and the illustrated build guide accompany the files. The editable CAD archive is a subset of the project, rather than a complete offline guide. For the full documentation, use the online build guide. Links in the bundled documents need a full copy of the GitHub project to open correctly.

My starting settings for Prusa CORE One HF / 0.4 mm nozzle are Devil Design PLA, 0.12 mm layers, 40 mm/s perimeters and 30 mm/s external perimeters.

Start from the official profile for your printer, nozzle and material. On CORE One HF / 0.4 mm, choose 0.15mm STRUCTURAL and apply the layer height and speeds above. On standard CORE One / 0.4 mm, use that machine's official profiles.

No profiles or macros are bundled; your slicer's current selections or defaults may apply on import. Check them before slicing. These settings are a starting point, not a guarantee for your machine or material. Do not add a brim or supports inside the moving button's clearances. Inspect the cassette layers and transitions in your own slicing.

I printed the rear cover with light supports under the screw cutout: from the build plate only, a large separation distance and low density. These supports are optional. The 3MF does not save support or brim settings; add the rear-cover supports in your slicer if you want them. See the complete printing guide. No G-code is supplied: slice for your printer and material.

Put it together

Work with USB and other power disconnected. The illustrated cleanup and assembly guide shows the parts and the three removable pads.

1. Remove only the three temporary cassette pads. Keep the captive button, guide, legs and hooks. Do not pull the button out or force a pad that has fused to the part.

2. Fit the cassette from inside the empty shell, before the board. Both hooks must engage; do not push the cassette through the exterior button hole.

3. Place the two square M3 nuts in their channels. Hold and align them until the cover screws engage; there are no printed keepers.

4. Outside the shell, fasten the board to the carrier with four M2.5×6 screws. Insert the module from the rear, screen forward and USB toward its cutout. Hold the frame and edges; do not press the LCD.

5. Engage the rear cover's upper tongues first, then seat its lower edge. Start both M3×8 screws and tighten gently in alternation. Do not use them to force a gap closed or sink their heads into the cover.

6. Without power, check that the board is flat, the cover sits evenly and the button moves freely to the first BOOT click and releases. Do not press past a hard stop.

The cover photo shows the current printed and assembled enclosure. Only the two printed nut keepers were removed from the plate; the rest of the geometry is unchanged.

Screen examples, rendered in software, show paused, completed and error states. The assembly pictures are CAD illustrations of the printed parts.

Install and connect

Use a computer and USB data cable. Open the browser installer linked in the project's official release notes, and make sure it matches the non-touch board and firmware version. You do not need to compile code.

Use Chrome or Edge (Safari and Firefox are not supported).

The installer asks you to confirm the board, USB connection and erase step before writing. Initial installation erases the display's existing settings; it writes to the display, not the printer. Keep USB connected until it finishes.

Before joining the display's setup network, stay on your home Wi-Fi and collect your home Wi-Fi details, the printer's IPv4 address, PrusaLink port and PrusaLink password. On CORE One, the PrusaLink Password goes in the setup page's API key field; it is not your Prusa account password.

Then follow the display's setup screen:

1. Join PRD-Setup-… using the password shown on the display.

2. Open the local setup address shown on the display, normally http://192.168.4.1.

3. Enter your home Wi-Fi details and choose Check this Wi-Fi.

4. Enter the printer's IPv4 address, PrusaLink port and API key, then save.

5. Return to your home Wi-Fi and compare the status shown on the display with the printer.

For the complete steps, updates, changing settings and recovery, use Build and set up your display and Installation, updates and recovery. Hold the display's button for about two seconds and release to reopen settings. If the printed button feels stiff, do not force it. Disconnect power and check the assembly.
