+I [@Wackerbarth](https://github.com/Wackerbarth) tested this version on my Kossel Pro and Arduino 1.6.5 for Mac.
+This configuration is a transition to merge Terence Tam's configuration with up-to-date Marlin source and a current Arduino IDE

+# Configuration for Kossel k800 XL
+This example configuration is for a Kossel XL with a printable bed diameter of 280mm and a height of 380mm. It also has the auto bed leveling probe (with an endstop switch) and the heated bed activated.
+
+## Configuration
+You might need (or want) to edit at least the following settings in `Configuration.h`:
+* `MANUAL_Z_HOME_POS` - The available height of your printing space. Auto Bed Leveling makes it less important to have the exact value.
+* `DELTA_PRINTABLE_RADIUS` - The printable radius is how far from the center the nozzle can reach.
+* `DEFAULT_AXIS_STEPS_PER_UNIT` - Steps-per-millimeter for the delta steppers, and for the extruder [to optimize the amount of filament flow](http://zennmaster.com/makingstuff/reprap-101-calibrating-your-extruder-part-1-e-steps).
+
+### Fine tuning
+* Increase `DELTA_RADIUS` if the model comes out convex (with a bulge in the middle)
+* Increase `DELTA_DIAGONAL_ROD` if the model comes out larger than expected
+
+### [http://reprap.org/wiki/PID_Tuning](PID Tuning)
+* `DEFAULT_Kp` - The proportional term
+* `DEFAULT_Ki` - The integral term
+* `DEFAULT_Kd` - The derivative term
+
+### PSU Options
+* The power supply is configured to 2 (to use a relay to switch 12V on and off)
+* It is configured to be off by default
