Version 1.3.25T / 12.01.2014
- M105 use the wrong convert function for Heatbed Target Temperatur - Correct bug in calculate_trapezoid_for_block(..) - smoother Steps for arc funtion G2/G3 - example for HEATER_DUTY_FOR_SETPOINT for reprap-fab Extruder V4 - more cycles for Autotune (M303) old 5 cycles, new 7 cycles - New Thermistortable for ATC Semitec 104GT-2 (Type 5)
