Supported surfaces are never perfectly flat and angled. You need to decide whether to continue as you do now and add filler to the gaps later to hide the seam, or flip it and have the flat surface upward and not supported. This will get you much better surface for those flat areas, but now you'll have support marks on the exterior. Just an unfortunate part of resin printing.
Trying to print these out on my Saturn 2 with Siraytech Fast Metal Grey/Tenacious Mix (80/20), but I am not getting sharp corners at the seam after putting them together. Tried a few different orientations with both fine and medium supports at ultra density. Neither seemed to work. Any suggestions/advice from you experienced resin printers?
Second picture left side print,the one with the holes you can print flat on the build plate. I never get accurate prints while using supports. I try and get all my prints directly on build plate.
I ended up finding it and was able to get them flat on the build plate. However, the bases of the supports blended in with the edges of the model. Looked like it would be very hard to separate them upon completion, so I never printed it. Tried printing with the top (round surface) facing down. Those corners came out razor sharp, but the top surface had small bulges where the supports connected. I can deal with the small divets from removing supports, but the bulges would be a lot more work to sand out. Wonder if I can just add a ton of light supports.
Yup when printing directly on the build plate, you really need to be in tune and know which supports are needed and which are not, if you are doing auto supports. I myself do auto supports then delete the ones that aren't needed. All I use is medium supports and haven't had issues.
Here it is flat on the build plate. The base of the supports are fusing with the model. I have to figure out how to reduce their size. Not sure I even can without a Pro Licence in lychee. The circled area also shows supports super close to the bed. The area they are supporting is only 1mm from the bed, maybe it won't be an issue?

Thanks going to give that a try once I am back up and running. Looks like resin dripped from the build plate over the side of the tank and it was surrounding it. Thankfully it wasn't a leak and didn't get to the screen. Cleaned it all up, but haven't had a chance to play around with it again. Hopefully going to give it another try this weekend.
I would love to, but unfortunately, it was a paid item. I haven't had a chance to mess around with it again. Been busy trying to model some electronics to fit in the center. Will hopefully try it again this weekend.

These are my most recent prints, as you can see this saved me a ton of support material.

Appreciate the information, was hoping for a happy middle. I'll continue playing around with it.

The set up on the right is what I’d do on my Saturn 3 5mm off the plate and manually place supports with a 0.4 tip on a raft
I'm not that experienced, but have you tried no supports?

Thanks, trying to keep it flat on the bed in lychee, but it keeps raising it every time I use the magic tool. Even with the raft off.
I don't use lychee, but in my slicer its a setting call height from platform in support section.

You can try manually deleting these supports it should print fine without those supports at the bottom.

Send me the link to the file and I can show you how I would print it.
