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
Do you find ABS sticks that hard when it cools down? I've never needed anything to get something off my heatbead, when it cools to around 80c i just knock them off, always have.
