touch auto bed level on Geeetech aluminium

[khschmidt]

Hello,

I have ordered an Geeetech Aluminium and I want to upgrade the printer with auto bed leveling.
This Printer has a Sanguinololu Board. I cannot find any hints for upgrade the Printer with this board.
can anyone help?

best regards
KH

I have the acrylic version and I installed this - http://aus3d.com.au/ir-z-probe

I had to modify the board slightly to power the Z probe and then connected it to the Z-max end stop (although be careful which pin is which)

Thank you for the Information, but I have ordered now a GT2560 board, because I need an additional pwm for a fan and the sanguinololu board has no free Pins and the compiled Software does not fit into the Controller with 128k Flash.

OK, the GT2560 is what I have on my printer.

I had to solder some wires to the board to get 3.3V for the sensor and connect to the Z-max end stop. I then hot glued the connector to the board so it doesn't move around.
