Im not sure I'd go that far (and Im an owner of both). NMTB/QC30 has
positive drive but a R8 power drawbar absolutely whoops QC30 in tool change
speed ease. Push button vs having to yank on a wrench both in and out.
Its not really an improvement.

How long does it take to lower the table far enough to extract
well it might be faster for one tool jobs but 5 or 6 tools already touched off
might make the qc a better choice

I've got an Erickson QC30 on my Bridgeport CNC mill.
R8 does not maintain any accurate Z reference after a tool change.
So while you can change tools quickly, how much time does re-referencing
the Z axis use on repetitive parts?

Hi Viesturs
Paused at 0:57 and I see 7 ropes.
Right, I didn't notice this. Maybe the plan was to have 8 but one of the
drives died. :-)
And at 3:17 I certainly do no understand,
what kind of g-code is that, it seems to use G01 and G02, but the axis
words seem strange.
Indeed, looks

I have just started using the R8/Tormach toolholding system and find it
