Can I get some help in getting up to speed with DLP printing?

@Gary_Hodgson what were you thinking of implementing for the tilt mechanism?

Also, what did you coat your vat with?

Coating was very thin PTFE film (link is in the blog post I think)

For the mechanism I was going to implement a stepper rotating with a cam which pushed the vat down slightly - the vat being raised on some springs.

Another design that I heard about just the other day was to have two steppers drive the Z axis independently - and have the G-code lift one side slightly first, and then the second rise to join it.
