# This macro was provided by discord user Garrettwp to whom i give my thanks for sharing it with me.
# I have tweaked it a lot.
#
# this macro is  based on the great Annex magprobe dockable probe macros "#Originally developed by Mental, modified for better use on K-series printers by RyanG and Trails"
# that macro can be found here https://github.com/Annex-Engineering/Annex-Engineering_Other_Printer_Mods/blob/master/All_Printers/Microswitch_Probe/Klipper_Macros/dockable_probe_macros.cfg
