TEVO TARANTULA AUTO BED LEVELLING - E3Dv6

Auto Bed Levelling for the TEVO TARANTULA with the popular LJ12A3-4-Z/BX-5V from eBay. Print with the large flat section facing down on the bed.

No more servo's no more touch probes!!

I designed this carriage as I was tired of having to level the bed almost every print. It uses 3 roller's instead of the standard 4. The carriage sits nice and square now and you only have one eccentric nut to worry about, HEAPS easier. I've also included a small recess for the X limit switch bolt heads so that they no longer drag along the X axis.

I have used the proximity sensor with the part number listed above, but the standard one that works from 6-30 volts will also fit in this carriage, but you will need a voltage divider before wiring it up, there's a thousand videos on youtube if you don't know how to make a voltage divider.

Firmware attached in the .zip file is the Marlin firmware that I am currently using in my Tevo, there have been some notes added through the 'Configuration.h'
