Just unpacked and set up last night. Turned on and it started to calibrate but got hung in the right rear corner vibrating against the metal frame. It appears the printhead wants to go further back into the machine which would be off of the print bed. The sticker in machine said customer service until pm but apparently they changed to 7pm. Any suggestions would be appreciated. I am brand new to 3D printing and I hope this isn’t a sign of things to come ! !
