Build Your Own SLA/SLS

so i'm getting a great finish and amount of detail but i'm getting a curve in the x axis. any pointers?
pics to follow when i make them small enough to load

Post the pics to www.imgur.com, I don't think they have a size limit (within reason).

sorry for the bad pics, only have the camera on my iphone
it looks worse in real life
but as u can see with the pegs
the whole think is tilted like this

It looks like your petri isn't clamped down hard enough, or maybe something wasn't tightened enough during assembly, or perhaps something got tightened at an angle?

The Dish one makes sense, since the angle changed directions. i'll try again

still getting the curve, in the same spot each time, any ideas?

it seems to be right at the height when the prints start to stick out of the resin, is it possible im putting too much resin in? maybe causing a surface tension?
or could it be mechanical? could my balls be out of line on my rails?

If you have a dial caliper you should check to see if your Z axis is running straight. From my experience, resin level really shouldnt affect the print unless you run out. Youre curing at the bottom of the resin the cured resin should not curve after its been cured.

slight off angle caused by a cross threaded screw on bottom
thanks guys
