For those that going to calibrate MINI , you don’t need to put the scanning board on the angle , just angle the MINI focusing on the small dots as guide for the horizontal line until it appears green .
Use some light on the side , not calibrate in dark light conditions, I used the Revopoint LED on this side .
I calibrated using this software 3 devices, the results was 0.0235 what is the highest I ever got with fantastic scanning results and sharpness even on my Mini Beta device .
But before you start back up your original calibration settings , do at least 3 tests before you process , the lowest will be your best score . If the score is not above 0.1000 just leave it the way it is .
The software will tells you if you need to calibrate or not .
Issues like lose tracking usually have nothing much to do with bad calibration .
Calibration issues are :
1.Textures do not align correctly with the model, you see dark patches
2. Your markers do not appear red while using marker mode
3. Your scanned model don’t have even surface , a lot of lines appear on the surface
That are the major reasons you want to re calibrate .
Losing tracking is the last reason you want recalibration, you will have the other issues above with it if you really do as they are all connected.
Keep the original calibration backup in a safe place just in case things don’t works well after recalibration like for example moving the board in place of the scanner to pass the difficult steps , you don’t want to do that . Always move the scanner never the board .
If you have the original POP2 board , you can place the MINI board on top the angle when the process ask for , but it is not really needed , you can put your MINI at the angle and finish the process as well.
The scanner will take series of pictures while calibrating and based on it adjusting the alignment in the firmware , it will not move the sensors but align the data they produce . For that reason it is important to take your time in this process with a little of steady hand and patience is required
