# MK4duo 3D Printer Firmware for Arduino and Arduino due ## Version 4.3.05_dev

Special thanks

• Wurstnase
• thinkyhead @Scott Lahteine
• all Marlin developers.

New features are:

• One version for Arduino and Arduino DUE. All board 8 bit are supportated.
• 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?)

Quick Information

This version of Marlin was made to accommodate some requests made by the community RepRap Italy http://forums.reprap.org/index.php?349

The new features are:

• A single Firmware for all types of printers; Cartesian, Delta, SCARA, CoreXY & CoreXZ.
• The possibility of having only one hotend independently from the extruders that you have.
• The addition of the 6th extruder.
• Management Color Mixing Extruder
• System Management MKr4 for 4 extruders width just two drivers and 8 relay.
• System Management MKr6 for 6 extruders width just two drivers and 8 relay.
• 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.
• Adding Debug Dryrun used by repetier.
• Added total Power on time writed in SD CARD.
• Added total Power consumption writed in SD CARD.
• Added total filament printed writed in SD CARD.
• Added anti extruder idle oozing system.
• Added Hysteresis and Z-Wobble correction (only cartesian printers).
• Added support reader TAG width MFRC522
• Added Cooler and Hot Chamber
• Added Laser beam and raster base64
• Addes Mesh Bed Level (MBL)
• Added Stop and Save for Restart (SSR)
• Added Nozzle Clean Features
