Hello Anders, Thank you for your input! I am from the R&D department at UM, working on the new nozzle design. If I am correct your design has 2 new features: A toothed ring to hold the heater and PT100. Separation of the nozzle and the heater block, so the nozzle can be replaced without taking off the fancap. Regarding the toothed ring: Nice idea! Does it work better than the screw? Have you changed the positions of the PT100 and heater cartridge so they are 'level' with the ring? Regarding the separate nozzle and heater block: Good idea. Replacing the nozzle is made easier, because the heater cartridge and PT100 can stay in the heater block and the heater block can stay in the header assembly. Good! You have changed the nozzle design. I expect more oozing. Can you check? How is retraction? The melt zone is longer. Therefor I think you can work with lower temp? The heater block is higher. Please check if the heater block does not touch the fan cap. This can change the thermal dynamics. Have you tried using other diameters nozzles? Again, thank you for your input! I will make shure we discuss this in the team. Kind regards, Jan
