Prusa printers are well known for being very silent even in the standard modes. But actually, our printers also offer an option for even quieter operation. Please refer to the instructions below to learn how to switch your printer to stealth/silent mode.
Power modes for the Original Prusa i3 MK3
Normal vs. Stealth mode
MK3 printers offer two print modes. Normal mode is required for the detection of lost steps (shifted layers), while still being quieter than the silent mode on MK2/S. There is also the Stealth mode, which utilizes Trinamic StealthChop technology, making the printer almost inaudible with the print cooling fan being the noisiest part of the printer. However, Stealth mode does not provide lost step detection.
These modes can be switched depending on the situation:
- When idle LCD Menu - Settings - [Normal / Stealth mode]
- During a print LCD Menu - Tune - [Normal / Stealth mode]
Power modes for the Original Prusa i3 MK2/S/.5
Power vs. Silent mode
The MK2/S/.5 printer offers different settings for motor power consumption. Silent mode uses less current and makes the printer quieter, but less powerful. Hi-power mode is great for very large (over 200 gram) prints. It is also recommended for newly assembled kits before you fine tune everything. If you experience lost steps (shifted layers) or if you’re manually adjusting the speed of printing to more than 100%, use Hi-power mode.
Auto power mode
There is also a brand new Auto Power Mode. Essentially, it's between silent and high power modes. The stepper currents depend on the Z height. The current starts low when the Z height is minimal. And it increases slowly as the object is printed.
These modes can be changed in two ways:
- When idle: LCD Menu - Settings - [Hi-power mode / Silent mode / Auto power mode]
- During a print: LCD Menu - Tune - [Hi-power mode / Silent mode / Auto power mode]
