From now on we have a new section on the website for technical information. The goal is to have short question-answer type of documentation, with additional pictures. You can reach the section by navigating to customer service pages, but the information is also linked for relevant products from the documentation section on the product details page. We are going to fill op the section soon, if you have a question not answered here, please contact technical support (techsupport@reprapworld.com).
