Thanks for all the feedback! Got to say I love this forum and the general helpful vibe!
So, to reiterate after spending a couple of hours in the shop tonight.

Turns out the Plasma was set to Gouging instead of cutting which explains a few things. Not too surprised as I suspected that my own lack of experience was to blame.

The V-shaped bearings of the Z-assembly weren’t properly preloaded which accounts for the wavy cuts. https://youtu.be/-oeJZzzHURw

At the end of the session I understood what several of you pointed out re the X-axis lead screw and nut mount. Very loose. https://youtu.be/HEl0aKIkieA
Still might have an issue with THC and possibly the X-axis. This was cut prior to point 3 was corrected so might in part explain the offness of the cut. However, it doesn’t explain why the torch was plunged into the material.
Recorded the screen of the cut so would love to har your comments as to what THC is up to around the 50 sec mark.
