[QUOTE="zero_zero, post: 313343, member: 9932"] 1. Calibrate the build plate 2. Make sure the bottom of the buildplate is rough enough for the resin to stick, use a 200 grit sandpaper of rough it up. If find the resins I am using react somewhat with the aluminum (ie. i see black marks on the paper tower when I wiping it clean) that leads to the bottom to smooth up with time. I re-sand prolly every other week. 3. Try some see-through resins first, the cheapo ones, till you get the hang of it...they tend to print faster and with ease. Pigmented resins are more finicky 4. Before you print make sure you mix up the resin in the vat with the plastic spatula, the pigments settle on the bottom and not letting the light through 5. First few layers needs to be overexposed like 60-80 secs, and you need a big enough support surface to stick to the buildplate, nesting is important: [ATTACH]34642[/ATTACH] 6. Decrease the motor speed to about 160-180 um/sec for more gentle peel offs, see my current setup: [ATTACH]34641[/ATTACH] 7. I got thirsty from so much writing :banghead: [/QUOTE]
