  1. Overall size is approximately 87x60x24 cm. When installed, visible height is ~17 cm . Printed with PLA+ on Ender-3 Max, made of 9 large parts joined together. Designed in Blender, sliced in Cura 5.2 & 5.3-alpha -- thank you Ultimaker for the new multiple tree support!
  2. Genius! Thank you! Gained 5+ h print time and saved 20 m filament.
  3. Hi Aldo, I'm new to Cura and 3D printing, I think this is awesome! Owning an Ender 3 Max. Does any of your plugins support sending the extruder to the topmost Z axis position while printer is idle? This functionality would be useful when replacing the extruder nozzle, cleaning a clogged nozzle, or changing the filament. Thanks.
  4. I suppose Blender's manifoldness and Mesh Tool's watertightness verification algorithms are significantly different. Most of my Blender models are found not to be watertight in Cura. They print as expected tough.
  5. To follow up on this, the Ender 3 Max fan is a beast. To avoid warping, I need to turn the fan on at a height of 10 mm or greater (layer 51 in my case). I get good glass bed adherence only if first layer temperature is at least 70 ⁰C. I realize this may be PLA brand-dependent as well so I have to experiment more.
  6. My interest in this topic is related to printing large objects that I intend to use around the house. I chose an Ender 3 Max (advertised to do 300 x 300 x 320 mm) and Cura. After some trial and error I managed to print my first large project: a flat (~390 x 290 x 5 mm) divider for my freezer drawers, made of 2 overlapping parts designed in Blender and assembled together with snap-fit joints. I successfully printed out 2 copies and then I ran into a "not sticking to bed" problem that required a reevaluation of most adhesion parameters previously used. Here is what works for me right now (brass nozzle 0.4 mm; PLA filament 1.75 mm; bed cleaned with 70% isopropyl alcohol, not 99%): - Layer height: 0.2 mm - Initial layer height: 0.2 mm - Top/Bottom thickness: 0.8 mm - Printing temperature: 200 °C - Printing temperature initial layer: 210 °C - Build plate temperature: 60 °C - Build plate temperature initial layer: 70 °C - Print speed: 40 mm/s - Initial layer speed: 5 mm/s - Enable print cooling = False - Build plate adhesion = True - Build plate adhesion type = Brim (8 mm) - Z Offset = -0.05 mm [using 'Z Offset Setting' plugin by fieldOfView] - Enable draft shield = True [Experimental setting] - Draft shield X/Y distance = 10 mm Setting the offset to -0.05 mm after bed leveling is important as it seems to enhance bed adhesion. Enabling the draft shield is a condition to avoid warping; not sure whether it works by preventing drafts or by providing additional mechanical stability to the printout but I find this feature particularly useful in my case. The parameters above give me a nice-looking printout. The problem is that it takes 25 h to print one part and 21 h the other. This is still acceptable for now as I only need 4 copies for this project. Soon I will start a new project, where I need to print 6 different parts of a ~900 x 600 x 250 mm object. I feel that, with the inevitable trial and error required for optimization, my next project may take months to complete. Any suggestions?
