# Prusa Mk4 printer

I built one from a kit!

## How-Tos

### Unbrick a messed up firmware update

The [instructions](https://help.prusa3d.com/article/fw-in-internal-flash-corrupted-13608-mk4-21608-mk3-9-23608-mk3-5_401125) say to push the Select knob in once while trying the firmware reset, but I found I had to continually push the knob on and off repeatedly to "catch" the bootloader at just the right time to allow for a forced reflashing of the firmware.
