We can discuss more about moral issue regarding to patenting in another topic. Patent exists and we have to deal with it. What is keeping my attention here is more about what we can or cannot do.by SolidUtopia - General
Heated build chamber patent limitation - 11 years ago
Hi, We don't see a lot of 3d printer equipped with heating chamber because of stratasys patent limitation. I looked into theses 3 patents US6722872: US7297304: US20040104515: Basically all independent claims refer to a "x-y-z gantry located external to the build chamber", "thermal separation between the heated build chamber and a gantry that controls motion" And this one from US 7297304 B2by SolidUtopia - General

Quotebilsch Sadly, I don't think I can get 1/32 on a ramps 1.4 board - anyone know if otherwise? Hi, I did change my pololu A4988 on ramps 1.4 to DRV8825 at 1/32 microstep. You can use the same jumper on the ramps to decide of your microstep ratio. Take care to put it in the correct orientation, the trimpot is located on the opposite edge of the drive. It doubled my resolution as I can see itby SolidUtopia - Printing
