  3. Yes, I can't see why this works the way it does, the way the 2+ primed was much simpler and less messy, just extrude a length of filament from a height, then retract whilst moving to the start of the print, the S5 method seems overly complicated and makes either a mess on the nozzle or across the bed. @SandervG could this be looked at,y S5 is better than my 2+ in all areas appart from this, this actually is not as reliable and clean as the simpler 2+ method. Thanks
  4. I think with the last update the prime blob was edited a bit in how it works so it does seem to drag a bit of filament across the build plate now. It really could do with lifting the head more when it primes so that it don't get filament stuck all over the nozzle what then drags some across. Maybe @SandervG could pass the feedback on to the right team members.
  5. Bonjour, Je test l' UM3 depuis peu et je n'arrive pas à bien régler l'extrusion de pièces simples fines et hautes 100 x 20 x 8 mm? Ici en image les 2 doigts en PLA blanc imprimés ensemble verticalement on des traces symétriques sur les 2 et 1 doigt en PLA gris a d'autres traces différentes. Comment obtenir une surface nickel bien lisse comme je vois ailleurs ? Mes réglages : PLA blanc mat Dailyfil à 215° - fill 20% triangle - 60 mm/s - décal Z - ventillo 100% PLA gris Ultimaker à 210° - fill 20% triangle - 60 mm/s - décal Z - ventillo 100% Merci pour vos idées.
  6. That's because I have it set in the extruder gcode. If you need to adjust it just change this number for both extruders and make sure the end code is a - number to retract.
  7. Thanks. Software side it works basically the same as Mark 2, hence similar CURA and E3D profiles. Nice post. The 1.75 hotend runs with a custom 6.35 OD 2 ID PTFE bowden tube, sold by the same Taobao seller. The major advantage of this PTFE hotend is that there is pretty much no chance of nozzle jam or clog for PLA even with frequent long retractions. With the PI insulator ring applied, the PTFE last much longer and can also handle high temp materials. As for using E3D heatbreak, the current heatsink probably won't be able to cool it down properly because the surface area is much smaller. You can consider trap a piece of 6.35 OD 3.2 ID or 5 OD 3 ID PTFE tube inside the heatsink. I think the 4*3 PTFE would deteriorate pretty quick due to thin wall thickness, and it is also too soft to hold up to the compression from filament. Making 1.75 and 2.85 hotend components swappable isn't all that necessary. You would need to make compromise on both sides to achieve that. I think it would be better to make two entire printheads with 12pin connector for quick swapping. That would be much less hustle, much more reliable and cost very little.
  8. Hi , i run Ultimaker 3 a lot since i gut it in december last year. No problems did always firmware upgrades. Now first time last week print stopped in the middle and API sayed something of reason reboot ok but now i have an 20 Hours print in the making and (it runs in the cellar ) i lost connection to the printer Cura 3.6.0 didn't show anything and web browser showed swagger and api did respond but no picture. i ran down happily the printer printed when i came down i tried curl -X GET --header 'Accept: application/json' 'http://192.168.178.33/api/v1/system' and looked ok at curl -X GET --header 'Accept: application/json' 'http://192.168.178.33/api/v1/printer' i got ok answer and curl -X GET --header 'Accept: application/json' 'http://192.168.178.33/api/v1/print_job' showed ok but video didn't work at all an hour later video worked ? So how can i avoid that or how can i switch back to last version which seemed stable till you fix that behavior funny extra fact curl -X GET --header 'Accept: application/json' 'http://192.168.178.33/api/v1/camera' shows an 404 ! even if Cura shows now the film ? so what is the best to do ? thx thomas
  9. i think to have find a BUG, when i use 2 material (1 nozzle with Y bowden) on my anycubic kossel plus (marlin 1.1.9) option to "print sequence" (the way to print 1 object completly then another) disapper... why ? i think is becasue i must use 2 prime tower in this way ? BUT This appen also when anyway i use only 1 material.... for example only material from extruder 2... (i have 2 different extruder motor 1 mk and 1 bmg dual....sometimes 1 is better than other)
  10. I glanced at the thingiverse link but there are dozens of stl files there and I'm not sure which one is fuselage3 and sorry but I'm just 1% too lazy to download it and open it into cura. Could you please post 2 photos - one of the part in prepare mode and one in preview mode so we can see what you mean? It's great that you posted the STL for people who want to experiment but please show the issue that you are talking about visually.
  11. Have worked out a lot of issues but stumped on this one. Cant seam to get cura to properly print 2mm hollow vertical tubes correctly, if I use a single .4mm line it is ok, but walls to thin, looking for .8 - 1.0mm thickness. If I increase line width or line count, holes get filled? https://www.thingiverse.com/download:5582605 This is a piece of the puzzle, union overlapping is off, .4 nozzle, have tried different line width's, line counts, speeds, layer heights.... Have to be missing a simple setting? any thoughts will greatly be appreciated randy fuselage3.stl
  12. A new plugin is joining the plugin family! The CATIA plugin comes basically with the features you know from the others (if you had a chance to use them before).[1] The plugin can be easily downloaded and installed on my website. You can find a very basic checklist of what needs to be done here: https://thopiekar.eu/cura/cad/catia/ Enjoy and happy designing! -------------------------------------------- [1] https://thopiekar.eu:5443/cura-cad-integration/CuraCatiaPlugin/commit/9413a9961f0782a152b9bd878adcb23ade342cbb --------------------------------------------
  13. Made these 2 custom downspout diverters. Each one is a different angle. Used openScad to design. S5 to print. zero support was needed. Oh - also the brown barrel has a white hose clamp that I modeled in DSM and printed with Nylon filament.
  14. The top looks fine. Do you mean you have a problem with the side of the print? You need to explain the problem better. By the way you can't print this part in this orientation without support - those 2 overhangs will try to print over air and the filament will just droop down. Did you create this model? Or did you download it? If you want to preserve those granite-like shapes and you want them on both sides then this will be a difficult print. If you want the side to be perfectly smooth then you can put the side you want to be smooth down and move the print downwards into the bed in cura. If you want all sides to be smooth then you need to get a better CAD model.
  15. So is this tinkerMarlin that is doing this? Or Ultimaker Marlin? This exact problem has been reported quite a bit for tinker Marlin but I"m not too surprised if it's in regular marlin also. I recommend you go to tinkerMarlin version 16.01 and/or if you have tinkerMarlin (any version) it seems to crash less if you turn off "geek mode". https://github.com/TinkerGnome/Ultimaker2Marlin/releases/ Scroll to the bottom and hit "next" to find 16.01. Then click "assets". 16.01 with geek mode off seems to work really well. Even with geek mode on it seems to crash less than all the newer versions. There's a long discussion on this topic on github in tinkerMarlin in "issues".
  16. If you try using the ironing function you may find that will improve the top surface for you. I have only tried it once and in parts of the model it was gobsmackingly good but in other parts it was poor. But I was using Cura 2.7 and I suspect it has been improved in later versions
  17. @Render did you ever finish the firmware? Love the looks of it
  18. Who would have thought ? What are GLOBAL settings then and why they are shown by default ? Thanks for a hint.
  19. For the first issue, check out the “Extruder 1” tab in the profile dialog.
  20. Hi all, I thank you help. Cura 4.0 2 extruder printer. My printer is stopping many times in the same position for most of gcodes. In one of them I looked for the error using gcode.ws analyzer and I found the problem. The first 3 layers (raft layers) are printed with same material (220ºC): -First layer printing ok. -Second layer the printer stops. ("Temperature error"). The command included in the gcode in the middle of 2nd layer: M104 S195 Extruder temperature modification was not needed. So, due to the extruder was printing at 220C, and should continue at this temperature (not 195C), extruder temperature drops down and the printer stops because the feeder can’t push the filament. Why Cura included this command? What can I do to avoid this problem in a long print? (hardest to find the wrong command). Another issue is the Preview of the printing process, it is not real. First layer in Preview is showing extruder 1 but in real it is printed by extruder 2 (what I had decided). I guess these 2 issues have no relation.
  21. thanks, yes i think you are right. I do find that the priming options available on the S5 are not great, the blob does this and with no blob you get streaks of material dragged across the plate !
  22. 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?
  23. I am stil on my first, but had to clean it last week. Used about 30kgs tough pla + pva.
  24. hey hey, our UM2 has just developed this error. often during a print the screen lock up with a couple of lines through it and the interface will stop working. when this happens the print will still _finish_ but the nozzle never retracts so it just sits melting wherever it stopped. i’ve updated the firmware (a couple of times) and tried with new SD cards but the issue still occurs, and i haven’t found any useful way of getting data out about how/why. my gut feeling is that it’s a hardware failure somewhere, but, i’m just wondering if anyone has worked out _what_ that is likely to be or been down this path already? it doesn’t seem to be a reset, because you’d expect printing to stop and the ui to function again, so i’m wondering whether it could be a power supply issue / brown-out, but there’s also not much in the way of power circuitry on the board that you’d expect to go wrong and i’d kindof hope the firmware would detect that. i’d much rather repair the existing mainboard than replace it if it’s possible, but, i’m grasping at straws at the moment as to _what_ would cause the problem.
  25. 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.
  26. Yesterday
  27. 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 ?
  28. 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.
