Novamill Z travel
Posted: Tue 18 Feb , 2020 0:00 am
I'm just looking round my "new" Novamill (it's not up and running yet) and I'm wondering if more of the Z travel could be used? Ideally in the VR mill software but failing that in Mach 3 etc, the limit switch would have to be moved etc.
The spec is 114mm, initially winding the head by hand up past the standard limit switch to the top of the dovetail (with no upper bellows) and down until it physically stops gave about 132mm, taking off the debris shield increases it to about 149mm but with 10mm of the bottom of the dovetail unused.
At this point while hard to see it looks like the simple square ballnut mount plate touches the bottom of the slot in the column "corner to corner", but only just and if relieved it looks like it might then physically move by 160mm of Z?
Of course I'd also need to add a column spacer block to make use of this travel IF possible as the head would be so close to the table! I'm just wondering if anyone's played with modifying this aspect of the mill at all?
