PSA to trained people.
The machine sustained some significant damage! The alignment on the column was massively out of what causing very poor performance. Some very concerning issues have cropped up in the Z axis screw that I will have to look into more. If you cause damage there is no culture of blame here but the damage must be repaired, not only so that others can enjoy the high quality of work the Taig is capable of, but so that your own training can be improved and this kind of damage prevented in the future!
On a side note the spindle is at the very end of its lifespan, it may fail very soon and will have to be replaced.
