I’m new to this forum, with the printer (P1S) arriving only yesterday. That said, I received an error, related to the Z-Axis as well, and I discovered that I had installed the plate so that the rear of the plate was extending past the end of the bed, which caused the rear of the plate to lift a couple of mm. This was enough to cause the Z-Axis error. But, as was the case with others, clearing the problem did not clear the error. I had to recycle power to get the machine to reassess the status, and come back on-line without the error.
