Wanhao i3 Auto Bed level System

thingiverse

Wanhao i3 Printer Modification Using two push button switches mounted on the machine. This is a work in progress, not fully tested due to existing firmware and switch type. New firmware must be loaded into the printer that supports bed leveling. The z-axis switch also needs to be set to normally closed. Two Arduino switches are used; it's similar to Adafruit part number 367 (www.adafruit.com/products/367). Tested with new firmware, it works perfectly. Used the firmware from groups.google.com/forum/#!msg/wanhao-printer-3d/pjWof2uIkNE/AjJ2oZicnF0J A bootloader was flashed to the printer by using an Arduino Uno as an ISP. After flashing, the new printer code was uploaded directly to the printer via USB cable. In pins.h, line 904 is removed to remove SD card support.
