Chitubox snip shows how I set up supports and 3mm Z lift on my last print using proven Elegoo Mars Red resin. Other photos show the first failure using Suraya Blu resin which seriously laminated. My theory is that on such a large model, you can't have a sharp change in section and I need to go in and add large blend radii inside the hollow shape. I may also try and do some infill but am not sure if that impedes the drainage of the resin from the hollow sections.
On the red resin print I didn't get beyond the raised platform before the print failed and the only bit beyond that height is the continuing support inside the router bit depth setting pocket.
I have moved the printer twice recently between homes but always in the supplied foam and box. I also have replaced the FEP film and relevelled the bed before these prints. I also greased the leadscrew as it was making unpleasant mechanical noises during levelling. Any help would be greatly appreciated as I am stuck at the moment and am close to resorting to constructing my jig out of wood!
Ok - did a bit studying and when I looked online for my Elegoo Red Resin I found this website with recommended settings for each Elegoo Resin. https://docs.google.com/spreadsheets/d/1...edit#gid=0 - wasn't terribly out. I also did a 30% infill and set the whole thing at an angle (one direction only). I did get a curve/warp at the first surface below the platform but as this was not critical to the part it was still functional. I think in future I will probably thicken the wall of this first face and maybe add some ribs - to make it stiffer. Photos of final project and resulting door jamb hinge slots shown. I will post the model on thingiverse later.
In the end I did make this in wood first as I wanted to get my new door up - but am confident this printed jib works almost as well.
