That of course disclosed that I wasn't anywhere near close enough to the bed for adhesion, so I raised the rear of it about a turn of the wheels. Then it started sticking. But there so little spring left to lift the bed that I'm going to modify the z switch to lower it another 1/8 ", which will compress the springs and make them far more repeatable.

That will effect infill density too I expect. So we'll waste an once of plastic and see how this one works. I can't go much finer as the gcode grows rather exponentially, its now 90% of that 8GB card they sent. So as I've 3 brand new 64G cards here, and I see a max of 32GB mentioned, I'm wondering what a 64G card will do to it. But cards are cheap at even Wallies as long as its not a SanDisk. They are cheap too, but the limited life makes them very expensive. > "support" is going to be needed for the upper flange.

Yes, this is all new to me, and I expect there will be a cost. Thanks Chris. Stay well now.
