Tevo Tarantula incorrectly auto leveling of bed

Question

I decided to try and setup the bed auto level sensor.

I downloaded this firmware: TEVO-Tarantula-I3-Marlin-Firmware and followed this tutorial, YouTube - Setting Up Auto Bed Leveling (Tevo Tarantula).

Firmware Config files:

• configuration.h
• configuration_adv.h

A few things happened after that:

1. The bed will not level
2. The Z axis goes up to approx. the middle...
3. The printer is in no situation to print

I probably got something wrong...

The machine goes to the leveling points, but is approximately 10 cm above the bed.

Answer 1

From your configuration.h file you see that (in line 643):

#define MANUAL_HOME_POSITIONS

is not commented out, there is no // in front, so this means that manual homing with accompanying coordinates is enabled.

This should not be enabled, as this setting is used by Delta printers only. This may cause the problems you experience as there may be some sort of a conflict between manual and auto positioning.
