I agree I think I will continue with some recalibration tactics before I start
messing with xy scaling. I just read through this
post,
and figured out that I need be more intentional about the height of the belt
loop around my anchor on the stud that goes into the concrete - at this point
I have just been letting it sit where it sits… So now I think I will build
various length spacers so that they all sit at the same height as the height
as the arm exits on the maslow (is that the correct way to do it? or should
they all be the same height and the machine self corrects for the different
arm heights?).
if you tell the machine the correct offset from the anchor to the arm, the
machine calculates the correction, but it is better if there is less offset to
correct for.
I did see a fair amount of wobble as the maslow cut the small circular pieces.
It seems like changing direction causes a bit of tilt as it gets pulled from
the top and torques around the base.It has got me thinking about maybe making a big aluminum plate to sit over the
plastic bottom and maybe try to nail the fit on the linear rods to make it
more rigid. It would lose some z height but might be worth it if it is
heavier and stiffer…
you can also make the bottom of the sled slipperier (wax or slippery tape,
teflon of UHMW plastic)
