I have been printing with WaxCast without any issues.
Here are some pointers that may help:
Build plate needs to be parallel to the vat.
Light intensity - 30 micron Z - 45micron x,y
Insure adequate first burn in layers
Make supports thicker than you would for other resins.
Make sure you have a large enough initial surface layer.
