Mini:

I installed the new bed leveling screws on the Mini (one was stripped and loose)

Prusa:

Prints do not stick to the bed.  I left due to the storm before I had a chance to see what was going on but did have two prints in a row fail.  The bed did warm up to temperature so I need to watch closer.  The auto-level was fine and the first layer was flat but then skidded off.

Taz 5:

Found some strange white Ninja filament in the printer but was alterted to a Z-offset issue.  I calibrated the Z-offset by turning the little knob next to the micro switch.  The Z-offset had an error of about 10mm.  The switch seems to dangle down so maybe the switch is starting to fail.  I did a test print after the adjustment and things seemed fine.

Taz 3:

A nice looking large print was sitting on it when I came in.  I removed it and had no trouble with a test print.
