Copy the config files from Marlin/example_configurations/delta/Anycubic/Kossel firmware folder to the main directory. Read through and uncomment the linear plus, set the heated bed if you have it and probe options. I am just setting up a linear plus, had good success with the small pulley version. I found the probe length needs be be adjusted by 1mm or so. Install firmware, run initialize eeproby cshunt - Delta Machines
