As for calibration, it is coming soon, after we implement variable laser power, and acceleration, Calibration is next on the list.
One step we have taken toward better calibration is we have come up with a better UI for entering the calibration points.
You can now move the laser beam around with your mouse and click on various places on grid paper to set calibration points. Its much faster than our previous method and I can now imagine it being reasonable to enter in 100 plus calibration points.

PS UserDefined
quite some time ago you asked a REALLY good question, something that is constantly on my mind and still is.
Why is the peachy printer able to print perfectly smooth columns but dose not achieve the same smoothness on other prints?
This has botherd me ever since I saw that first green column print.
I still don't have a definitive answer for that, I have tested and disproved many theory's so far, and I still have more theory's to test.
When I find out why I will make a thread on this. My apology's for not answering you with a simple, I dont know. I remember composing a rather in depth
answer in my head including all my theory's at the time, but Im sure I never went back and actually typed out a reply to your question.

No worries about not answering the questions. Naturally I assumed that your team is trying to make the best possible prints and would be pursuing that goal if you could.

The question was more to catalyse some thinking. I found the stairs of the purple rook to look very glassy, and thought it had just been a question of layers.

It might simply be that the glass columns were printed from high up and were straight, so the laser was interacting less with surrounding resin and produced a consistent surface as it went.

It could simply be a question with laser power, spot size, layer numbers, and print time. If you print it slow and take your time it may come out better?

In any case, Im already super impressed with the prints so far, and with better calibration for accurate parts, the peachy will have surpassed my expectations (which were still high) by far.
