I have an Anycubic Chiron that I've been using for over 1 year and it just suddenly started printing in the middle of the air and I can't figure out why. I've tried new files and old and the nozzle looks like it will start where it should and then it raises way up like 200 mm high and starts printing the file. I have the latest firmware and the only thing that changed recently is I uninstalled Cura and installed a newer version. Anybody know where I should look?
