Since 2 weeks ago, we started getting parts out from the SLA500 with
undesirable results unseen before.
>From the look of the part, it sure looks like after certain height of
building, there was a shift of about 2mm in the X direction & this off-set
position remained over the next 5mm build before it returned back to the
original position. It remained so for a certain height before the same thing
happened again with the literally same off-set & duration. This would self
repeat over & over again throughout.
The platform is well secured down & even if it's not, surely a mechanical
shift if any would unlikley yield such a consistent pattern of steps on the
part. It can't be the blade sweeping action along the Y axis either as the
shift is along the X.
I wonder has anyone out there observed this rather strange phenomenon & the
solution??
