Robo E4 Pro: Z-Axis Calibration

The first step in calibrating your Robo E4, complete Z-Axis Calibration before continuing on to Sensor Calibration.

Tools/Calibration/Z-Axis Calibration

You want to insert a regular piece of paper between the hot end and the build plate so there is just a little bit of friction. You can move the build plate up and down using the buttons on the screen. 

When you're done, click "ok".

After completing Z-Axis Calibration, continue onto Sensor Calibration, if desired. (recommended). The article on doing so is available here: Robo E4 Pro: Sensor Calibration
