Cones of Calibration coming out different across the build plate – is this normal?
​
Hey everyone,
I’m pretty new to resin printing and I’m currently trying to calibrate my settings using the Cones of Calibration V3.
I ran a test where I placed multiple cones across the build plate, but I’m getting inconsistent results:
- Some prints come out perfect (success cones look correct)
- Others fail or look under/overexposed
What confuses me is that I already adjusted and leveled my Z-axis, so I was expecting all prints to come out the same. Since the exposure settings are identical, shouldn’t the results be consistent across the plate?
Right now I’m using:
- Layer height: 0.05 mm
- Exposure: 2.2 s
- Bottom exposure: 25 s
- Lift height: 8 mm
- Lift speed: 60 mm/min
- Resin: water-washable grey sunlu
Is this kind of variation normal?
Could it be related to:
- build plate leveling (even if I already did it)?
- light uniformity across the screen?
- resin flow or suction forces?
I’m honestly a bit confused because I thought once the settings were dialed in, everything should print the same across the plate.
Any advice or things I should check would be really appreciated 🙏
