Sort of, but not really. I tweaked the material settings instead, as I wanted to get the settings such that I didn't have to worry about changing things evertime I printed.
I'm keen to test in 30xy30z and 50xy50z.
I've had success printing at 30 xy and 50 xy, but only at 25-30z. My 50 z prints have all failed. This was before I flattened my table, though. It also appears that the hotspot in my lamp was kitty-corner from the areas that were failing, so that likely also contributed. I also suspect I need to use a less pigmented mix for 50z, but I haven't really gone back yet to experiment since fixing my table.[/quote]
I too have recently had issues with a warped build table, thankfully that issue is now resolved. I also followed metalcasters advice and sanded mine down to the aluminium and adhesion is even better now.
I had about a .4mm "high" spot that wasn't touching the vat bottom. Flattening and sanding seem to have fixed that. Once I get the hotspot fully calibrated (just started messing with the printer again yesterday, actually) I should have eliminated most of the reasons for my 50z failures. Either tonight or tomorrow, I will try a tall 50z print again using my current resin, and see how that goes, before mixing up and trying a less pigmented mix. Or, I may just switch to B9 black. The MJ is a lot cheaper, and I prefer the color (especially for photography) but the black is fully tested, and works well at 50z
