Firmware WanhaoD6 v3.1.1 HD

Hi to All, after testing my Wanhao D6 for several months, firmware Marlin Version 1.1.0-RC8 02-27-17 Version 5.0 I finally realized that the original firmware 3.1 prints better on the first layer. Surely the Marlin has problems with the leveling system of the plate. Quite distressed I decided to take the original firmware and enter new menu items in "Maintenance - Advanced" and edit some of them: Lower plate 25mm Lower buildplate (the heated plate goes down to the bottom) Preheat all (Preheat Extruder and Plate "210/70", status Info) Stop heating (Extruder heating and flat heating, status info) Disable stepper The firmware can be installed either by Cura Wanhao or by Xloader included in the zip file. I hope to have been useful to the community. Special thanks to my friend G. Orrico. https://drive.google.com/file/d/0B4gK9ZEls7PLc1B1WkxJaDk0ZkE/view?usp=sharing
