Raptor 2.0 adopts 36 point bi-linear mesh bed leveling, much more precise than ordinary auto bed leveling. Before leveling, you need to set the Z offset according to below steps first: 

Choose “Motion” -> “Auto home”. 

Now you can see the Z axis coordinate, please remember that value as Z1.

Then choose “Motion” -> “Move axis” -> “Move Z” -> “Move 0.1mm”. 

Put an A4 paper between nozzle and bed, rotate knob anticlockwise to move down Z axis until it  can pass through ONLY one paper. 

Then you can see the current Z axis coordinate, remember that value as Z2.

Finally calculate the Z offset by below formula:  

Z offset = -(Z1-5-Z2) 5 is a safety value for Z axis lift up  

So here Z offset should be -(6.5-5-0.1)=-1.4 

Then choose “Configuration” -> “Advanced Settings” -> “Probe Z Offset”, set the Z offset as the  value you calculated by above formula. 

And save the Z offset by choose “Configuration” -> “Store settings”. 

If it’s saved successfully, you’ll hear a beep sound. 

then choose “Motion” -> “Auto home” again to keep safe distance between nozzle and bed.
