  1. I posted a reply to someone asking about longer-term reliability here. SandervG was kind enough to provide some thoughts on my issues and suggested a new thread if I had further comments or concerns. This is that thread. From my prior reply, I experienced a flood of the print head back in early-March of 2020. The print head was shipped to Ultimaker and they "bent it back into shape" per the Local Tech. I've had issues since that time, but the most recent issues have been communication error with the print cores (ER34), flow sensor issue (ER65), and I2C communication error (ER35). B

  2. We are happy to share Ultimaker 4.8 Beta with you. It marks a new step in the evolution of Ultimaker and perhaps the world’s most used slicer. You can help to make it even better for yourself and all its users by taking part in this Beta and report your findings back with us. So, what new features can we share with you today? Arrange models has been improved. Until now, the arrange models feature didn’t always utilise the available bed space to its fullest, which made a lot of users arranging their models by themselves. An improved arrange models feature should provide you

  3. I would expect values less than an ohm or so but as long as your meter sees a stable connection I would assume it's OK... it is fine to lay the printer on it's side. while printing with the printer on it's side is not recommended it does not matter to the electronics or the motors, etc. just be sure to work EMC safe.

  4. when you unscrew the bottom of your printer there is another one of those big connectors, it's easy enough to find and only logically plugs in in that one place. But even if you measure them and the connections are all OK, there might only be a break when flexing the cable. You could clean the contacts (for instance with alcohol on a cotton swab) re-insert and see if that helps.

  5. The i2c head communication error really does point to the cable, since that is only reported if there is no connection to a chip that is on the PCB in the printhead, regardless of temperature errors, etc it could of-course be a combination of things, but that seems less likely.

  6. Understood. I'm keeping the faith for now as I know only too well the issues introducing and supporting new products.

  7. Thanks for the logfiles! (the ones in the e-mail) Using the logfiles I was able to see a bunch of i2c head communication errors, so my thoughts go to the cable between the printhead and the printer. I think either the cable is broken or it's not plugged in properly. I can further support this conclusion because over the last few days I found A bunch of probing errors and min and max temp errors. The reason for those are all related to the printhead, the printcores, etc. the only thing all of those have in common is the cable from the printer to the printhead. Assuming there is

  8. Hi @Jman15x, Thank you for your message and putting the effort to collect all error messages and the links to the articles. I'm sorry to hear about the difficulties you are having with your Ultimaker S5 Pro Bundle. When updating to a new firmware version triggers more error messages, it is not necessarily that the firmware is faulty. Sometimes error detection becomes more refined, which detects 'errors' that previously went undetected. Not to say that it renders your product immediately as broken, but it should help to pinpoint which areas might be performing sub-optimal.

  9. @Bundle Thank you for your feedback. You explained to me that the situation you reported was for Ultimaker PLA, aborted while printing, based on the usual park position it was clearly higher up in the Bowden tube and the delay in extrusion for the following print was excessive (missed the skirt and started extruding already in the part section). It is indeed not expected that PLA creates a long tip after a print is aborted. It is one of the materials that creates the better deprime tips actually. Such delayed extrusion is not expected under normal circumstances. Sounds

  10. It's a question of scale. It appears to be drawn in English units. When I scale it up to 2540% it doesn't fit my build plate. At 1270% it is a single wall piece and does slice at .4 line width. At 635% it doesn't slice because the walls are too thin for my line width of .4. Search around here for cookie cutters. There was another post by about them and as I recall an acceptable solution came up. One thing you can do is make the whole thing a solid piece, set Cura up with "0" infill, no bottom, and no top. Then you can adjust the wall thickness until you get something useful. I

  11. Cleaning the nozzle is very important with PETG. Otherwise the filament will stick to the nozzle. In the case of larger parts, printing will then fail! For Cura / Experimental / Wipe please add these two options: 1. Additional cleaning at the start Should be executed after the "Start G-Code". 2. Additional cleaning at the end Should be executed before the "End G-Code". Thank you

  12. Thank you for your time and patience. Sometimes it hangs at that point. If it is obvious it got stuck you can restart (but don't get too impatient). Let us know how it goes when you have tried again tomorrow!

  14. le nylon adore l'humidité. par précaution il faut faire étuver ( four basse température) une bobine non utilisée depuis quelque temps. 50° degré suffisent généralement pendant 2 ou 3 heures environ. je pense que cela réglera tes crépitements. ps: méthode aussi valable pour le PVA également sensible à l'humidité

  15. Alors coupleur ... sérieux: vaut mieux savoir ce que c'est parce que c'est à l'origine de pas mal de cacas... Petite pièce en téflon qui isole le bowden de la partie chaude, à l'intérieur de la tête.. si tu ne sais pas ce que c'est, c'est que tu ne l'as jamais changé, et donc qu'il est grillé et qu'il étrangle ton filament... D'ailleurs normalement tu en avais un en spare part dans ton imprimante

  16. Just want to link a posting from Ralphoosh here too, because I think it is important when someone else reads his posting above and thinks that he just has joined the community to rant. We all know how hard the start into 3D printing could be, so we wish him good luck and success.

  17. Downloaded 5.8.2 and all appears ok. One question though-on aborting a print, the machine did a hot pull and then went through the cold pull as part of the abort/finish routine. This leaves the filament too far back in the Bowden tube with a long “tail” from the hot pull making me concerned about fully unloading the filament. I have had this occur twice. In one instance, I opted to retry the print but the core had lost its prime due to the extra retraction. Is this a new bug or have i just not noticed it before? Thanks

  18. hi all, cant be bothered to hunt for this but a few people asking about settings theyve lost for great prints but still got their gcode... easiest way ive found is... make sure your cura is same version or updated one. open cura...goto preferences...profiles...import.. goto your saved gcode on usb stick hd or card and click it.. ok the import. click on the new profile youve imported highlight and activate it... its now fully loaded into print settings on right hand side.. you can alter , rename or just slice and print anything youve placed on table using

  19. There are two build plates. Cura uses the dimensions (described by gr5) as a virtual build plate with X0, Y0, Z0 at the left front corner. On your printer, there is a physical build plate. If you think about it, nobody really knows where in space the physical build plate is. The "Home Offsets" in the printer sets a virtual 0,0,0 that then matches up with the Cura virtual build plate. The Ender glass plate I have is 235 x 235 and as I recall those are the dimensions in the Ender3Pro profile in Cura. If you jog the nozzle to the exact left front corner of the glass and then use "Prepar

  21. I don't have a material station so I am just guessing, but the problem is that a material profile needs additional parameters to be compatible with the material station. That's the reason why your Protopasta works in the standalone printer but not with the material station. 3rd party profiles are created and maintained by the vendor and it seems Protopasta has only provided a profile for the S5 without material station. So as long as Protopasta doesn't update these profiles you have to go with the workaround. But I think when you select on both sides the NylonX there is

  22. From what I understand of this issue, it's only manifesting on 8-bit boards, predominantly on ( but not limited to ) Creality brand printers like the original Ender-3. If someone out there has a stock Ender-3 and could specifically test this fix ( use the benchy boat to test ), you would be doing a huge favor for your fellow Creality users and the Cura dev's. I would do so on my own Ender-3 but I'm using an skr 32-bit board and my other Creality printer has Creality's 32-bit silent mainboard on it, both printers do not have this issue, yet a friends Ender-3 is seeing i

  23. You see, Greg. It's even harder for me to communicate with you and perhaps, from time to time my words are harder than I wanted. But we can also do it in German. But also understand that I'm really not satisfied. With version 5.8.0 there was the possibility that the filaments are no longer pulled back that far. That was very good. At the same time, however, a basic function no longer worked. Namely the unloading of filaments. So how I should change the print core or replace a filament if I've wanted to insert a different color? Waiting for 2h every time? Why was this not foun

  24. Hi Greg I feel like I'm in the wrong movie right now. Where did I use personal names? About yours? You wrote back to me in a public forum - signed with your name. And when I know the name, I also mention the name because I am respecably. Am I schizophrenic or have I misunderstood your statement that I shouldn't use personal names? I don't think so. And what's unprofessional here? I have proposed a solution for you: Stand up and say: Yes, our performance is currently not optimal and we have made too many mistakes. No, you don't do that: you just gushing about yours

  25. Could you also add the files that are called something like: ultimakersystem-ccbdd300129b.3.7.7.20201017.boot-0.log.gz? Those are the main log files. (the forum might complain about uploading them if so you can unzip them with tools like z7)

  26. Usually the hotends not heating up is related to the pogo pins between the printhead and the print core, try cleaning up the contacts on both sides and try again. The error is caused by protection code that hasn't been changed in this release. If you still think it's software you can try these steps: If you have any materials loaded try to unload them first, possibly do a factory reset, and then try again. If that fails you can downgrade to 5.8.1 via usb, here are links to the files, only one will work but select the R1 only if there is a robot on the side of your pr
