3.1.2 - RC1 firmware for Prusa i3 MK3

Summary:

  • accurate sensorless rehoming for crashdetection and powerpanic
  • extruder multiplier precission fixed
  • fan checks synchronization

Detailed description of changes:

Accurate sensorless rehoming for crashdetection and powerpanic

In previous version rehoming was not accurate and some small layershifts could appear in case of detected crash or power loss recovery. For proper function of accurate rehoming implemented in current firmware version it is required to re-run selftest.

Extruder multiplier precission fixed

In previous firmware version, there was inaccuracy in counted E coordinate in case that extruder multiplier was set with M221. For 50um layers, the precision loss led to holes in the print.

Fan checks synchronization

In previous firmware versions checking for fans were not properly synchronized with planned moves. Printing using very low speeds and long linear movements could led to false fan errors in some cases. This has been fixed in current firmware version.
