# MK4duo 3D Printer Firmware for all Atmel AVR boards and Arduino Due ## Version 4.3.1x dev

Special thanks

New features are:

  • One version for all Atmel AVR boards and for Arduino Due or other boards based on Atmel SAM3X8E
  • Stepping-algorithm optmized now for DRV8825 and A4988 (no need for double or quadstepping; no delays)
  • High speed stepping of approx. 295.000 steps/s, if needed (maybe more with less DOUBLE_STEP_FREQUENCY?)

  • Management Multyextruder NPr2, 4/6 extruders with only two engines.
  • Management Dual Extruder DONDOLO.
  • Adding commands to facilitate purging of hotend.
  • Step per unit varied for each extruder as well as the feedrate and the acceleration.
  • Added Autocalibration for DELTA
  • Added Autocalibration 7 points for DELTA (Similar RepRapFirmware)
  • Adding Debug Dryrun used by repetier.
  • Added total Power on time writed in SD CARD.
  • Added total Power consumption writed in SD CARD.
