  1. Hi everyone, thanks for your replies and your help. Even though I haven't been able to slice the previously shown model since I had the problem for the first time, I have tried to get behind this problem and implement your solution thoughts. But somehow I can't disable my second extruder. @tinkergnome @fvrmr It is still showing the grey area at the side as if two extruders would be enabled even though I have disabled the second extruder. (see picture) Also I have checked the spec sheet for the UM3E in which the build volume is specified with 215x215x300 as I have it set in my printer. (see 2nd PDF) @Torgeir Is this wrong? Sorry for bugging you again and thanks in advance 😄 Cura_Max_Volume.pdf Spec_Sheet.pdf
  2. Hey there, so basically I'm trying to print a round object with a diameter of 210mm on my Ultimaker 3 Extended. The Problem now is that Cura is unable to slice my object because "It doesn't fit the build volume". According to the spec. sheet of the Ultimaker 3 Extended, the build volume for single extrusion should be 215x215x300 so I should be able to slice and print this without any problem, since I'm not even close to some safety margin. I have already disabled my skirt/build adhesion and checked the machine settings for the correct plate dimensions. I have also tried disabling the second Extruder without any noticeable effect. Only thing I haven't tried is modifying the build volume to a bigger value because IMO that could damage/harm the printer in the worst case. I'm really stuck here and don't really know what to do except asking you guys for some advise. Anybody had the same issue? Thanks in advance.
  3. Hey there, For a few weeks now I'm experiencing extreme warping on the UM3E when printing certain geometry or sizes, especially on the models edges. (The model you see in the pictures is 100x100x35) I'm also getting a weird under-extrusion/skipped second layer in nearly every print, even in prints where the edges aren't warping at all (e.g.: some cylinder ⌀30mm). Warping currently only appears on PLA-prints, since I'm not printing "big" ABS-prints. Actions I have taken to combat the warping (without success): I have tried different bed temperatures (50-60℃) and different nozzle temperatures (200-210℃). I have printed with the standard Cura cooling settings and have tried to print it hotter (fan running only with 60% at certain height). I have printed with the printer enclosure and without and let the automatic levelling process run before almost every print. Did a full service of the printer cleaning the feeders, tightening belts and greasing the axles. Flipped the glass-plate I am printing with the current Cura-Version and my UM3E got the newest firmware. I'm at the end of my knowledge here and don't really know what to do anymore except printing with a different kind of PLA and printing with a different Printcore. Last possibility would be buying a new glass-plate/new Printcore, which I'm really not keen of, since I don't know if that's even the reason for my failed prints. I really hope somebody here got a solution or maybe an Idea how I could fix my Problem. I'm attaching some pictures of the failed prints and my settings as a curaprofile for easier analysis. Thank you in advance for the help. Settings_Cura_1.curaprofile
  4. Hi everybody, so I've been printing with my UM3E for a bit over a year now and so far I am actually quite pleased with the quality of the models coming out the printer. But since I got my printer I am having issues getting the quality of my visible walls to an acceptable level when printing circular/round objects because it seems as the printer over extrudes und produces blobs on the outer walls. I have attached some pictures of my most recent prints with the second picture being the worst of them all, looking at the inner side of the object. I've tried toggling different settings on or off or changing the values, but all that had barely to no impact. (retraction distance and speed/optimize wall printing order/Z-seam alignment etc...) I will also include some screenshots of my settings and a project file, hope that helps u guys 🙂 Thanks for the help in advance. UM3E_Trunnion_Ring_Body.3mf
