MK3S+: Every sampling is slow, as if the entire bed is at a height the printer isn't expecting. It would sometimes sample more slowly if there was a bit of plastic lifting the bed slightly at a sampling location. The printer is a factory-built MK3 that I upgraded to MK3S+.ħx7 bed leveling, 5 samples per spot, magnet compensation turned on.Īs a MK3, mesh bed leveling was decently fast: At each location, it did all five samples in very rapid succession.
