Well here is my plan of attack for the Z banding.

1. Replace plastic tube Z axis couplers with metal ones.

2. Replace the threaded rod as mine have wobbled since new.

3. Change from a mechanical relay to a SS relay so I can setup PID on the heated bed to hopefully get rid of the up/down movement of the build plate while the heat comes on and off.

4. If none of the above work I will change to Bowden extruder to take the filament pulling up the X carriage out of the equation and replace the heat bed with a bonded aluminum heat bed.

5. If none of those work I will take the electronics and extrusions off the printer and throw away the piece of crap wooden frame and start from scratch.
