  1. Past hour
  2. I experience a problem situation. When i use Polymaker Polymax (the toughpla equivalent), the end of the filament is often quite hard attached to the reel, so it doesn't come off; the printer stops, but at that moment i already have a small "defect" in the print. At this moment i unwind the last meters of the reel manualy, and remove the end. With a full roll, when i don't forget, i try to drill a hole, just at the place where the end is attached to the reel. How do others cope?
  3. I am stil on my first, but had to clean it last week. Used about 30kgs tough pla + pva.
  4. Today
  5. I'm using a 2 in 1 nozzle so I need it to purge even if it's for support material, but it never purging, since it's switching extruders it really should follow the same rules even if it's for supports. Makes it hard to use PVA supports if I don't get a purge on extruder switch. I assume for 2 colours this is working find but for supports it's not registering the nozzle switch it seems. Unless I'm missing an option that I can't find. Any help in this matter would be great, I can upload a code file if that helps to show there is no prime on support switch. Oddly enough in the preview the prime tower looks to be 100% support but it's only ever printing supports with E0 which is the main colour. The print it's self looks right and it is trying to print with E1 for supports but since there is no prime it's just not working.
  6. Yesterday
  7. When i edit settings from viewport, i set wall thickness to what ever i want, but when i manage profiles, it always shows 1mm thick. Why is that ? Why every profile i click in the profile manager shows same thing ? Why i cant create PLA or ABS profiles without #'s added to them ?
  8. Hmm, let's just do a quick test of that speculation... Firstly, I used infill line width of 0.6mm and this gives an extrusion rate of 0.075 mm/mm I then sliced again with an infill line width of 0.7mm and now I see an extrusion rate of 0.087 mm/mm 0.7/0.6 = 1.1666 0.087/0.075 = 1.16 OK, so the ratio of the infill line widths doesn't quite match the ratio of the resulting extrusion rates but it certainly doesn't look like a gross error there. At worst, there's a small rounding error but that may just be due to the short segment lengths used in this example.
  9. But all non-infill extrusions are not underfilled at all. Infill only ends up being grossly underfilled when I set a larger infill line thickness (e.g. 0.6 for a 0.4mm nozzle). Whereas Simplify3D produces G-code that makes proper infill lines when I use a default line width of 0.48mm for a 0.4mm nozzle and have the infill line width further inflated by around 130%. People have speculated that there is a bug in Cura that causes it to not increase the fill rate commensurate with how the infill line thickness is increased.
  10. Still using the one that come with my S5 here and it's still fine and i have 108 days of run time on the printer. It's likely you are using prime blobs at the start and you get left with a bit of filament on the cover around the nozzle due to how the prime blob works. So without seeing any image i would say its just burnt filament what you can just clean off.
  11. I sorry, but for me, the sliced model looks complete, nothing is missing in my opinion. If you just mean the texture, then this is a usual texture of a top layer in 3D printing.
  12. Zu 1: Kann ich denn nicht einfach in der jeweiligen Zeile den F Befehl und den Platzhalter weglassen, sodass nur noch der G Befehl und die Richtung vorgegeben ist? Also als Beispiel G1 Z0.6 anstatt G1 Z0.6 F{travel_speed} Zu 2: Genau das macht der Drucker auch er zieht nur 16mm vom ersten Extruder zurück und dann 137mm vom zweiten Extruder vor was die folge hat dass das Filament vom zweiten auf das erste auffährt. Das Projekt hab ich mal dran gehängt hoffe das passt so. Zu 3: Der Code selbst wird direkt von Cura auf einer sd karte ohne Nachbearbeitung gespeichert. Ich will eigentlich auch nicht unbedingt im Gcode was manuell ändern weil mir das ein wenig zu kompliziert und zu aufwendig ist. Hab mit G Code Programmieren seit der Ausbildung nix mehr gemacht und müsst mich erst mal wieder einlesen.😅 Test 2 Farbig.3mf
  13. Hallo, so Dein Cura Profil ist leider nicht zu verwenden, du müsstest über "Cura -> Datei -> Speichern" gehen. Ab Cura 3.6 muss die Dateiendung ".3mf" heißen. Mehrere Sachen sind mir in gcode aufgefallen, Dein Platzhalter {travel_speed} ist falsch, und für Vorschub gibt es soweit ich weis auch keinen Platzhalter der mm/min in gcode einträgt. Müsstest also dein {travel_speed} gegen den direkten Vorschub austauschen Es werden nur 16mm zurückgezogen, aber 137mm vor?? Ursache kann man vielleicht mit Hilfe von Cura Projekt finden Ich habe solche Fragmente in gcode gefunden "p�" oder "��" Das ist meist ein zeichen dafür das die Kodierung nicht stimmt (bearbeitest du den gcode manuell nach den abspeichern von Cura) oder irgendwelche Zeichen (ä,ö $ usw.) die nicht unterstützt werden Gruß
  14. Hello @Timbe, it's still not obvious what the problem is. It would help a lot if you could save the project file (File ->Save) and attach the resulting .3mf file to this thread. Thanks.
  15. Yeah, but don't forget to calibrate your extruder as discussed above!
  16. Sorry, I was on basic fuctions all this time, switched to Expert and the intial layer thickness you mentioned earlier popped up and upon changing that I got my 90 layers. That you for the your time and help Gr5. Gratelly appreciated.
  17. I have the exact same Ultimaker (2 upgraded to 2+) and the exact same problem (back left higher than back right) and no way to level the back. It causes my latest large print to fail every time. Why oh why did they only put ONE adjustment in the back? I hope someone at Ultimaker has ideas about how can we fix this.
  18. Here is picures from cura and pictures from 3d model. Missing top "textures" Hope this help.
  19. I don't understand your problem, so please explain in detail what you mean.
  20. Hello, bon le concentrique c'est pas top car la pièce est fragile niveau paroie, je suis repasser en triangulaire + flow 105%... on verra? Autre surprise impression foirée après 9h (merci AnyDesk pour arrêter la tache à distance) à cause de ce p- - - de PVA de m - - - ! en fait il à bouché ma buse BB à tel point que j'ai du la démonter. Le PVA sortait jaunâtre avant. Voici l'expérience en photos, cela se fait sans problème en étant calme et avec 2 clés de 7mm 🙂 une qui tient au dessus du thermistor et l'autre pour dévisser la buse. Le tube et la buse étaient remplie de PVA cramoisi impossible à retirer en atomique, du coup plongé 2h dans l'eau chaude, hormis l'électronique du printcore, j'ai pu déboucher le tube au cure dent et en soufflant de l'eau chaude dedans comme une paille, mais pas totalement la buse, le fil inox de 0.4mm ne rentrait pas. J'ai donc laissé sécher le tout et remonter la bête sur l'UM3 pour la réchauffer à 225° et déboucher à l'aiguille le PVA devenu fluide. Ensuite bobine PVA directe au four à 40° / 1h, rechargement, et méthode manuelle en poussant le fil pour purger la buse bien dégeulasse. Baisse de la vitesse à 30mm/s et là miracle ! ça remarche impec avec un PVA bien transparent sans crépitements d'humidité. Eh bin si on m'avait dit que le PVA c'était tant la galère... ? Je testerais l'ATLAS PVA FORMFUTURA pour voir si il est mieux que l'Ultimaker ? Aller je relance mon print de 20h doigts croisés + l'oeil d'AnyDesk
  21. Looks like Cura 4.1 Beta doesn't add this feature 😪 Simplify3D has very few advantages over Cura, but proper, fat infill lines when you assign a fat line width is one of them. Seems like an easy fix, hope this feature gets added.
  22. I make some model for 3d print but when i prepare for print got this problem. Model got sliced on top.
  23. Hello, i have problem with top of print. Model is sliced all time i try different position results are same. https://imgur.com/a/n5GTjj2
  24. Hi gr5 Side fans seem ok, I can print the same file on my other machines and they print ok I have about 6 sets printing at once on the bed and I still get those hands, it's almost like there's too much filament just before doing the long lines on the large object and it puts to much on to the smaller part
  25. Successfully using PLA 0.4 in Extruder 1 and PVA 0.8 in Extruder 2. However, I must override the warning/error msg from the UM3 that says different cores being used each time I print. Can this be a preference option so that we don't need to override each time?
  26. Yes, but only for that update as the firmware team removed that check again in 5.2.11.
  27. Ah I see so regardless of internet or USB updating it still needs to connect to the internet to verify. I'll give it ago then opening port 123 UDP
