It was most likely due to an uneven print bed for the first one, with the rest it would have been because I tried printing them flat and it stretched the wheels to try to support itself (even with supports mind you). I've had a few issues in the past with things being a tad flatter than originally intended which showed again on the test prints where the standard car orientation of all four wheels on the print bed somehow made the roof cave in. By that I mean everything except the wheels printed to the correct scale but from the bottom of the windows up the roof was flattened by about 35%.
It could just be me not using very good settings as I did try the tilted orientation once which yielded a similar warpage to the green. I upped the curing time from 7.5 to 9.5 seconds per layer, layers increased from 0.2mm to 0.3mm and the time between the LED screen curing each layer was increased. Seems to have worked a lot better with those settings though results and settings vary between resins. The green resin likes finer settings the most so I've gone and ordered some more.
