Bed leveling

rbandrewsI've found a way that works. For the Replicator anyway.
Start printing a tiny square on each corner of the bed. Adjust that corner's screw while it's printing so that your layer looks all right, then start printing the real thing.
The extruded filament is 0.14mm diameter, and the first layer should be about half the height of the filament, so 0.07. I can position it that closely with feeler gauges, but the problem is that that's actually thinner than the layer of ink on top of the painter's tape that I'm printing on, and more importantly, at that scale painter's tape is a squishy surface because of the adhesive. I might try paper tomorrow.
It also occurs to me that if the average gnat is maybe 2mm long, and 1/4 of that is abdomen, and I can adjust the balance reliably to about 0.02, that's probably 20 times finer than a gnat's ass. Actually balancing the platform to within a gnat's ass isn't anywhere close to accurate enough.
