![]() Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, ’s PC). Not only do you not need tools to pop a printed part off. A PEI-coated flexible steel build plate makes a big difference to productivity. The build stack has also been completely redesigned. To further enclose the build chamber the S7 only has one magnetically latched door. This filters the exhaust air of every print and also improves build temperature stability. It now includes an integrated Air Manager. The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers. retraction distance yet).ĭoes anyone recognise the rough surface and knows how to prevent it?ĭoes anyone have a profile to share that offers better results? With the temperature set to 250C (fixed) I'm now down to 0.5mm retraction 25mm/s without even the slightest improvement (I may have missed the sweet spot along the way and haven't increased e.g. I then lowered the same tower 50mm (keeping only the top 2 floors for faster testing), enabled the draft shield and fiddled around with different retraction settings. My Sunlu Filament Dryer S2 ran for (>6) hours 70C before I tried again, but there was no obvious improvement. The 2 little pinnacles on each floor are ok, but the surface and bridging are nowehere near acceptable.įirst I assumed wet filament. ![]() You'll agree from the attached photo that this was quite crappy. While printing, the printer is kept in a Creality flexible enclusure with no additional heating. The print speed is 40mm/s (4 slow layers), layer height 0.2mm, line width 0.4mm (using 0.4mm E3D Nozzle X for 1.75mm).Ĭooling is off, coasting is off, fuzzy skin is off, bridging is on (min. I have tried a temperature tower from (260 to 230C) on a 110C bed, 0.2mm layer height and 0.8mm retraction at 40mm/s. My current struggle is with ASA though (Filamentum ASA Extrafill "Traffic Yellow"): I can't find the proper settings for a profile (Cura 5.2.1). Results for PLA, PETG, Ninjaflex and PA12+CF15 filament are great. a 32 bit Creality board and custom Marlin 2 firmware). I'm running a Creality Ender 5 Pro, upgraded with a Hemera Direct Drive (incl.
