It seems that the curl normally goes upwards. In our SLA250 with
SL5170 the curl definitively goes downwards. Depending on the hatch
parameters it curls more or less, but always downwards.
So the engineerings brain combines that if it is possible to curl
upwards and to curl downwards there must be circumstances where the
curl is completely compensated.
Now I'd like to do some research and ask for somebody to send me a
part complete with all build parameters or better the complete build
files (I need the .r, .l, .prm and .v file fitting for the
traditional buildstation software). I whould build that part on our
machine and compare it with one built with my own parameters.
Perhaps there are other parameters (Temperature, humidity, resin age
etc.) which have an influence in curling.
So, any commitments are welcome and I'll post the results.
Best,
Markus Hitter
