Hi @Friedl_1977 we’re so sorry that the local team there hasn’t been able to support you. I see my teammate @Shiden has also supported you on a parallel thread Printing Reliable functional parts with From4, truth to myth? - #8 by Friedl_1977, but if you’d still like to connect directly to our support team, the next best step is to get in touch with our centralized support team directly. Please email support@formlabs.com and that will open up a case with our agents, regardless of your location.
Orientation is definitely a case by case issue and by working with you directly can better understand what might be going wrong in your case. Thanks so much for your patience.
