This will be a bigger job than the X axis, not least because it's about 1m long and has a lot more of the treacly grease on it. I suspect it was also less well protected from swarf and coolant so may take more effort. Off we go....
Refitting the Z axis ballscrew assembly:
Back in position
Telescopic way covers:
These are a bit grubby but clean up nicely using WD40 and a pot scrubber. This is the main cover that covers the bed between the headstock and the saddle.

Clean up the toothed pulley. Somehow it ended up with grease in the tooth. Ho hum!
