I am printing with FORM 2 for about 3 years now, It prints about every two days. mostly large prints between 5 to 10 hours each. Resin mostly Tough 1500, sometimes White, Durable, Clear or Elastic.
When my warranty expired I started cleaning my mirrors when my prints started getting blurred and merged. Printed optics test, It was bad, than I cleaned them following instruction PDF. Test print exelent.
First it was year between cleaning, than half a year, now it wasnt even month between cleanings. (just 25 days)
Is there some thing that could have caused this? Is it just degrading quality of old printer after itss warranty? Did it happened to anybody else?
