· I have a print that has three filaments (white, clear, and soluble; position 1, 2, and 3). When I slice my model, Slicer uses all three filaments and then puts in a layer for filament 5. I tried setting the extruders by right clicking on the part in Slicer and specifying only filaments 1, 2 or 3; however, Slicer continues to try to use filament 5 which is unloaded.
We add new features, fix reported bugs, tweak and tune various parts of the code to improve the performance… and the firmware for MINI is no different. The MINI also meant moving onto a brand new 32-bit platform (the MK3S still uses an 8-bit board), which brought new challenges but also allowed us to implement features that weren’t possible before – like Prusa Connect web-based UI ...
Prusa is doing an amazing job on continuously improving the firmware they supply to run their 3D printers. Bondtech is also doing an amazing job, if we can say it ourselves, on adding value to the many already awesome Prusa printers. Our hardware does add something extra to the Prusa units, and because of that, we always need to sprinkle a bit of firmware magic dust to every new version Prusa ...
When printing on a powder-coated sheet, clean it with IPA. After printing, wait for the model and sheet to cool down before removal. Adding more perimeters for more solid parts. If you want to print truly solid parts, try to increase the number of perimeters instead of adding more infill. Postprocessing. PETG can be easily sanded both dry and wet.
Open PrusaSlicer, click on the 'Configuration' menu, and select 'Flash printer firmware' (left picture). Click on the Browse button (green arrow right picture) and choose the .hex file from the location you unzipped it. The file name with the firmware for the MK3S is prusa3d_fw_MK3S_x_x_x_xxx where the x is the firmware version number.
· By default, all Original Prusa i3 printers are shipped with the 0.4mm nozzle. In case you change the nozzle, you can set the correct diameter in the printer's menu (see Settings -> HW setup -> Nozzle d.). The printer will then compare the stored value of the nozzle diameter with parametres in the G-code. If there is a mismatch, you will be informed to prevent a print failure.
If you print for a long time from a single type of filament, such as PET-G, the filament can create a thin layer in the nozzle. This can cause stringing as the strands of the filament stick to the surface of the print. Therefore, thoroughly clean the nozzle before printing and make sure that any dirt or remnants of previous filaments are removed from the nozzle.

Prusa Research is a 3D printing company based in Prague, Czech Republic. It was founded by Josef Prusa, one of the core developers of the Open Source project RepRap, in 2012 as a one-man startup and grows to a 400+ team now. His open-sourced Prusa i3 design is according to 3DHubs the most used 3D printer in the world. We are shipping more than 6000 Original Prusa i3 printers per month to over ...
