u/Physical_Ad_26

Stuck in endless loop. The issue: if the mat is already physically in the machine when you power it on, the sensor trips and won't recognize it again. Solution: make sure the mat is completely unloaded before powering the machine on. Once it boots up, then load the mat. After that, it recognizes it and works fine. This sensor behavior isn't explained anywhere in the docs, cost me hours of troubleshooting.
