    Today's tweaks;
    The Z-axis lead screw was wobbling at the top (slightly bent lead screw) & there was a definite gap in the upper mount, probably not terribly important, but it bothered me, so I machined a tiny nylon bushing.
    No wobble now,.. but still have to beat the slight bend out of the lead screw sometime.
    Also, the heater bed wires sometimes fell behind the bed when it was fully down, getting pinched in the process.
    Put an ultra weak spring on them to keep them forward/under the bed. (stretched the spring out even more after the pic) Could probably just as easily used a rubber band.

    PS: - Removing "STUCK-ON" ABS from Kapton?..drizzle a little IPA around the edges while warm, pops right off! (Works for old hot melt glue also..doesn't dissolve it, just breaks the bond)
    - Kimwipes work for cleaning hot nozzles (Kleenex SUX!..been there, done that!.. gooey/lint mess!) they also work well for lint-free bed cleaning with IPA
