+# A [save_variables] block is needed since a printer save variable needs to be used to have it available after power up.

+# I like to hide that file as there is nothing in that should be modified by the user.
+# Do a klipper restart after adding the stuff above
+#
+# After klipper is back you need define your first plate e.g.
