I fired up my new A1 (second unit) today, went through the network setup, connected to Bambu Handy, and initiated the first-time calibration. As soon as the z-axis approached the top, the machine made a couple of popping noises and stopped, giving me the “Calibration failed” and then on the next page, “Z axis homing failed; the task has been stopped. [0300-40000 260310]”. The second possible issue was the extruder eddy current sensor error. See the attached picture. I have rechecked the hotend connections under the printer and all are tight and properly connected. I even re-seated the usb-c cable to make sure. I checked the connections in the back of the hotend; both were tight, and with an ohmmeter, checked a little over 3 ohms. I have a support ticket in. I just wanted to check and see if I missed anything. Any help is appreciated.
