Polar Cloud for Anycubic 3D Printers
Anycubic’s Klipper printers, including the Kobra S1, S1 Max, and Kobra 3 family, connect to Polar Cloud through our polar-cloud-klipper plugin once the community Rinkhals firmware is installed. After setup, the printer works like any other in Polar Cloud. Older Anycubic printers connect through OctoPrint.
Connect Your Anycubic Printer
Before you start, have your Polar Cloud Username (the email you sign in with) and PIN handy. Both are in your Account Settings after you sign in.
