+# Readme
+
+These configurations activate many of the new advanced features of the Marlin firmware:
+
+ * Auto Calibration
+ * Auto Bed Leveling
+ * Pause & Filament Change
+
+**Important**: Before doing anything else after updating the firmware, go to `Configuration > Advanced Settings > Initialize EEPROM` to get rid of old configurations.
+
+After that you should connect the Z-Probe and start `Configuration > Delta Calibration > Auto Calibration`. When it's done don't forget to also do `Configuration > Delta Calibration > Store Settings` to make it permanent.
+
+You should also do a `Motion > Bed Leveling > Level bed` followed by `Store Settings` to ensure a perfect leveling.
+
+Please do a manual paper test (moving the nozzle slowly down to Z0 and checking with a piece of paper). If it's not perfect, use `Configuration > Advanced Settings > Probe Z Offset` to correct the difference and execute the calibration again.
+
+**Also Important**: if you value your Z-Probe do NOT execute `Configuration > Delta Configuration > Probe Z-offset` - This can destroy the Z-Probe, see issue [#11337](https://github.com/MarlinFirmware/Marlin/issues/11337).
+
+# Select the Configuration
+
+**Please select the correct values at the start of the Configuration.h file**
+
+The Kossel comes in 3 versions:
+
+ * Pulley
+ * Linear
+ * Linear Plus
+ 
+Pulley and Linear use the same configuration, the Linear Plus is bigger and uses slightly different configurations.
+ 
+Typically the probes for the Anycubic Delta Kossel printers come in two different versions. 
+
+  * Version 1: Z Probe Offset of -19.0mm
+
+    ![Version 1 Probe](images/Version1Probe.jpg)
+
+  * Version 2: Z Probe Offset of -16.8mm
+
+    ![Version 2 Probe](images/Version2Probe.jpg)
+
+If you select the `ANYCUBIC_PROBE_VERSION 0`: It's very important to follow the correct procedure to set it up after flashing the firmware, otherwise you might damage the printer by ramming the nozzle into the buildplate:
+
+* `Configuration > Advanced Settings > Initialize EEPROM`
+* `Motion > Move Axis > Soft Endstops` : `Off`
+* Auto Home and slowly move the nozzle down until it barely touches the bed. (Do a paper-test: A normal sheet of paper should just feel the drag of the nozzle) and note this number.
+* Subtract this number from the value in `Configuration > Delta Calibration > Delta Settings > Height`. (If it's negative, add it).
+* Save and try the paper test again to verify your height.
+* `Configuration > Store Settings`
+* Motion > Bed Leveling (using paper test)
