SO...... I'm new to 3d printing and after extensive research ultimakers are an excellent choice and since its a small investment for a small company in a few week i will be placing an order for a UM2+ or the UM2+ extended. because im interested in printing materials such as delrin and ultem PC etc (which need high temperatures close to 400 C ) can you please help me by proposing a list with an upgrade kit (hot ends extruders hot plates etc) and a firmware which i can adjust the temperatures and other adjustments ? i hope i can get some help
