My Form 2 used about 3 years and it starts getting problems from couple of months ago. I tried to found the problems, cleaned tank and laser window with IPA, changed the new resin, updated the firmware as well as PreForm. But none of them work.
The problem looks like the cure power is not strong enough which cause the print break after about 2mm height, also left a lot of half cured tiny resin residual in the tank.
Is there a service need for Form 2 every couple of years? Like clean the laser or calibration the power? Or the laser head does have a lifespan, it need to be replaced after certain hours printing?
Thanks for any kind of help.
