  1. i'm having issues with mine. where some cones on the failure show, but at the same time, barely any of the success cones are made well enough to connect. is there anything else that i should edit besides exposure time?

  2. My favorite calibration test: a humble 10mmx10mmx10mm cube. (Often set to 5mm height to save time)

    It's so simple to measure with calipers and understand what you need to do to the exposure. After that is dialed in the cones of calibration to test tensile strength and that tells me how many and what size of support I need.

  3. But… What about ALL THE OTHER SETTINGS FOR RESIN AND PRINTING OTHER THAN EXPOSURE TIME 0_o

    In Lychee at least. Burn layers, normal layers, number of layers, layer thickness, transition count, lift speed, retract speed, wait before print, wait after print, wait after lift, light intensity….

  4. I see a lot of videos on exposure time, and not a lot of UV power, I know some resins make recommendations on this, but they also recommend exposure time, wouldn't it make a big difference as well?

  5. Cones of Calibration is definitely mini prints ONLY, validated this with 25-30C temp resin and "overexposed" according to CoC. Anything over 250g would fail with heavy supports, upping exposure time despite working on other printers etc.
    Warhammer minis it works great.

  6. 5:00 Freaking what dude? The test on the right is clearly the better of the two; do you even know how to use a calibration print? The line voids at the right end of the bottom row are filled in while the lines above are clear until just about the end, showing clear signs of overexposure. Reaaaaaaaaally shouldn't be posting tutorials with such a poor grasp on the basics.

  7. Hey Man! Awesome review, thanks a lot. I was wondering where I can buy that Centipede/Wormlike creature you have there? is there any patreon or something like that?

  8. Thanks for the video. Had a saturn 2 for 2 years and hasnt been great experience. Finally was able to get it to print decently but wanted to move to bigger higher detail stuff. Do to that i started over to fine tune my printer and im about to hire someone cause im at my breaking point lol

  9. If only exposure time was the key to great prints, all these these prints are meaningless if you are not controlling all your other variables. Ambient temp leads to more fails than exposure time. For me its Cones of Calibration every time with a new resin as 90% of my prints are pre-supported patreon/MMF prints

  10. Biggest factory not mentioned: temperature in the room the printer is in. I printed in a 73 degree room at 3.5s just fine, moved my setup to the basement and had to print at 5s to pass the cones of calibration test. The basement is at least 10 degrees colder than my upstairs. Lessons learned.
