Test print quality questionable

Post#1 » Sun Feb 11, 2018 6:06 pm

Hi guys, I purchased a used B9Creator V1.2 and am trying to start doing my first prints. I tried with both Cherry and Emerald resins and the test prints look virtually the same to the naked eye, but the fine details on the prints are clearly not great. Which adjustments would you suggest for me to make to improve the quality of the prints?

I used MSM 1.0 and MSM 1.5. The pictures I will attach are at MSM 1.5. And of course I changed the print material settings when I switched the resins.

Any input will be greatly appreciated.

Thank you,

First I would suggest you go back to the focus. make sure your settings are the same.
are you printing in 50, 70 or 100 position on your printer.
you will need to use the appropriate calibration for that.
then set the focus to match the calibration looking at it from UNDER the window to be as sharp as possible.
then you will need to post your settings so we can see what your using

Like AK says, Looks like def out of focus. The co. calibrates and does a test print before shipping, but focus can change in shipping.

AK, am I to understand that the sharpest projected grid should be on the bottom of the vat window rather than the top where we place the calibration paddle? I feel like this would be hard to really accomplish for mere humans, is there a trick I'm not thinking of, or am I just misunderstanding?

It is recommended to focus to the under side of the vat window if your using the paper grid if your using the plastic grids you focus from the top.
Note that there is the small thumb screw behind the projector for fine tuning.
To make it easy to work with I remove the door at the hinges. I know it's a PIA to do so but it makes it soooooo much easier.
I actually left the screws off and just pulled the door off and set it aside while I do what I need to do inside the printer then just set it back in place and the magnets hold it just fine ( it only took me a year before I figured that out )
