+[title] Download Bear calibration firmware
+[* 10] The Bear extruder is slightly taller in Z than original MK2.5S and MK3S extruder. We then need to temporarily flash a firmware to pass the Z calibration and selftest. After those steps we will flash stock firmware again.
+[* 9] For security reason we recommend to print ONLY with stock firmware.
