  2. Superhero's never die... ** early "Mark2" dual print...
  3. @tinkergnome thank you to answer me... I was referring to the Ultimakers printers (because I have the Ultimaker 2+ extended). All Ultimaker printers are already configured in a way that works perfectly as soon as you turn on the printer. The latest Ultimaker printers, as you said, are already configured with another Flavor and ready to use without the user having to think about GCodes. So I thought it might have something similar for 3d printers like my Ultimaker 2+ Extended. Because of my need to constantly change the specific settings in ultimaker Cura for my detailed statues-oriented projects. I have realized that I need to switch Flavor to Marlin so that I will have access to temperature settings and other specific functions that are hidden when I use Flavor Ultimaker 2. I am using the ultimaker Cura 4.2.1 (most current version). Sorry for my insecurity, but the only thing I would like, as I am inexperienced, is to be able to switch the Ultimaker 2+ extended Flavor to Marlin and have no problem. I confess to you that I have no knowledge of GCode. So my fear of inserting any Marlin Start and End GCode. Does Marlin's GCode Start and End work perfectly for Ultimaker 2+ Extended? Or do I have to make any changes to the codes? If you can guide me better I would appreciate it very much. Thank you so much
  4. if it's structurally ok I think it is worth it, you can make it as cheap or expensive as you want (or can afford) First thing you can do is measure resistance of the bed itself, the PT100 inside (the temp sensor) should be around 108 ohm at room temp. The Heater part around 3,9 ohm if I remember correctly. I think motors hardly ever break, so its probably the stepper driver on the board. If the machine is as old as this one it will have a 5th driver on the main board you could remap this motor to (more info in this forum) But first simple swap 2 motors and rule out the motor is broken I would definitely replace with something like the original, I see 3 options; - use the upgrade kit, but it's pretty costly - buy some original UM parts, like the metal parts and the olson block, and get the rest chines clones - buy all chines clone stuff, you can be lucky but there's a chance stuff won't fit very well In case you would need to replace electronics I would get an Duet3D board, wil give you immediately a more modern printer, more silent and network connected. Yep, you can plug in a 108 ohm resistor, it wil tell the printer it's at 20c..... but be careful not to turn on (or even connect) the heater.... If you want it to be original the kit is a nice and easy option. If you spend a bit more time, you can save money. And alternatively you can get an Bondtech feeder iso the Ultimaker feeder (I would recommend this...) If you want to get it running with less investment just print a feeder... many UM2's ran on it for there first years... https://www.youmagine.com/designs/alternative-um2-feeder-version-two Sure, no problem, just change the E-steps . If you use the "tinkerware" firmware (you should..) you can just set it from the menu. Don't know the correct steps by hart but it's in this forum somewhere, just ask again if you can't find it. did you know you find all parts and partnumbers, and the CAD file of machine here; https://github.com/Ultimaker/Ultimaker2 https://github.com/Ultimaker/Ultimaker2Plus Good luck, enjoy your new printer. Oh and obviously check if the XY axis are straight, and replace the belts, most original Ultimaker spare parts are pretty affordable (except electronics and the feeder) if you buy them separately. Depending on where you live you may need to email your reseller a list for them to order. Some resellers keep a good stock.
  5. So I will not do that. The support from which I purchased the printer told me that I could use 1.75mm filaments just by tightening the Feeder tension until I felt that Feeder would pick up the filament without problems. They showed me a picture of a person tightening the Feeder screw. Process similar to the link I put in the previous post. They didn't tell me about the serious problems you just told me. @SmithyThank you so much for letting me know.
  6. I'm not sure what exactly the question is... Newer printer models from Ultimaker or in general? UM3 and S5 are using gcode flavor "Griffin", it is very unlikely that this will be back-ported to older machines. But the differences to "Marlin" are marginal (a special header section and one or two custom gcodes). My recommendation is to use a recent Cura version with "Marlin" for UM2. Do you have concerns?
  7. Don't do it without physically changing the hotend, melted filament will not only come out of the nozzle, but also come out on the upper part of the nozzle and hotend, resulting in a mess of plastic.
  8. Today
  9. @johnse I confused myself a while ago. For lack of experience, I thought 2.85mm filaments and 3.00mm filaments were the same thing. I thought people referred to 2.85mm or 3.00mm as if they were the same thing, just a way of expressing themselves. But of course after much research, I realized that the filaments were completely different. Last week I was able to buy from 2.85mm filaments and I ordered a 1.75mm filament sample. That way, I'll try to test the ultimaker 2+ extended without physically changing anything on the printer. I'm not sure it will work, otherwise we would have already found someone who had positive results using 1.75mm filaments on ultimaker 2+. The little I researched, I saw people succeeding in making physical changes to ultimkaer 2+ to succeed, just as you did. I was surprised that your changes didn't work out and that they gave you problems. Which made me very sad because I need to do something about it. Importing 2.85m filaments is a solution, the problem is the delay in getting the filaments, and the high taxes when they get here in the country. But if I have no other option, the way is to always import 1.85mm filaments anyway. Or find another way ... I do not know. I also wish you success. And please, if you know anything about making the Ultimaker 2 + accept 1.75mm filaments, be sure to share things here. I will report my experiences with my tests here.
  10. I don't believe that it happened. I seem to remember there were plans for at least three contests but, for whatever reason, only two of them occurred.
  11. I have seen other threads on here about such conversions, so a search might be fruitful. i have also seen where people were misled by the fairly common mislabeling of filament as 3mm. While some “3mm” filaments are really 3mm, many are actually 2.85 mm but the stores round up for whatever reason. You did mention importing filament to be a possible option... there are many online suppliers with a very wide array of 2.85 mm filament. Good luck on either finding a supply or making your conversion.
  12. More likely I'm thinking something is broken in your UM3 print head. Try putting other cores into the right side. Do they go up and down when you slide the lever?
  13. Instead of just using one hand, try using the other hand to squeeze from the nozzle to the clear part. Slide it up and down many times. Where is it sticking? The spring can get jammed and start to come out of the clear part. Taking the clear part and spring off is easy. Try doing that and putting it back together. Here is a detailed video of taking your core apart but you only need to remove the clear part so it's quite simple. Full disassembly is really a last resort and can destroy your core but taking off the clear part is simple.
  14. Yes, you should start moulding on a printed model or on a testpiece anyway, until you have the procedure in your fingers. Don't experiment on sensitive persons. The application of liquid silicone itself on the hand would probably cause no problems, it is just a thick liquid. But the removal of the cured silicone might: you would have to pull and slide that cured silicone off, or cut it off by going under it with scissors. Both will require some force and shear action: in a normal person this is no problem, but on a very sensitive or weak skin it could do mechanical damage. I would suggest you make a silicone impression of one of your fingers: fill a tiny cup with fast curing liquid silicone, put your finger in it, let it cure, and then try to slide it off. This will give you a good subjective feel of it. If you do the moulding on a 3D-printed plastic model, you can cut the silicone in two pieces with a sharp knife (scalpel), or with fine scissors. But I still don't get the purpose of printing a PLA glove? PLA is very hard, and due to the layer lines, and it being biodegradable (=eaten up and broken down by bacteria), bacteria can get a good grab onto it. This might cause health risks. Also, you can't desinfect PLA-prints very well: the desinfectant may not get into the tiny openings. And PLA softens from 55...60°C on, and melts from about 80°C. (I heard from doctors that sometimes PLA supports are used internally in the body during surgery, when putting bones back together, because they gradually dissolve and get replaced by the own body cells.) You might consider moulding the whole glove from silicone: start with soft and comfortable inner layers, where they will touch the skin. Then gradually add layers of stiffer silicone on the outside. If more stability is needed, you could add stiffeners/thickeners into the outer layers of the silicone, which would make it stiff like a car tire. Or add a hard outer shell on top of the soft silicone. Then you have both the comfort of the soft inner layers, and the stability of the hard outer layers. The biggest advantages of silicone are: it can be from skin-soft rubber up to stiff rubber (depending on version), it is chemically almost inert (can be chemically desinfected), and it is temperature resistant to 150...200°C (can be autoclaved). Solvents like alcohol do get into the silicone, since it is a little bit porous to oils and solvents (not to water: it repels water), but they do not destroy it. Maybe you might want to contact a special effects shop, or people in the special effects branche (film studio, art school), and ask how they would do it. They use these things daily and have much more experience than I have. And they will know all the risks and caveats. I only use silicones occasionally, and then only a few dental versions.
  15. I'm excited to find out. The silhouette at the start shows two bowdens but only 1 wire sleeve so while I would hope for something along the lines of the mark2 or better yet, 2 separate heads that can be used in parallel the splicing idea sounds more likely. I do think there are two different machines being released and one of them is either sla or multi spools. Just guessing. 🤔
  16. I'm so sorry this happened to you. 😞 I was thinking of doing the same things you did. In one of my searches, I went to the 3dsolex website, just where you bought your kit. Before I physically made any changes to ultimaker 2+ extended, I thought about testing the Feeder tensioning technique the same way that this person did. https://learn.adafruit.com/using-1-dot-75mm-filament-on-ultimaker-2/overview For me it's a case of utmost importance and need to make Ultimaker 2+ Extended use 1.75mm filaments. Because here I only find 1.75mm filaments. And importing 2.85mm filaments would be very bad for me. Perhaps the Ultimaker manufacturer could create a specific solution or kit for users who need to use 1.75mm filaments. And if users wanted to return to using 2.85mm filaments again, this return could be accomplished easily and smoothly. (The ultimaker would give users a chance to work with both 2.85mm and 1.75mm filaments.) I realize this suggestion of this possible 1.75mm filament kit would be a successful sales suggestion. But I know it would be very difficult for them to create and manufacture.
  17. Thank you for your replies. The moulding ideas are interesting. I think that nothing can be moulded directly onto the skin because of the damage that the process would cause. I like the idea of moulding 'hard' silicone onto the printed hand. That could provide parts that would to some extent be self-supporting. It might even be possible then to get those parts scanned and print them in PLA. Actual gloves are not possible because sliding them over the fingers would remove the epidermis (the outer layer of the skin). It has to a a two-part solution that can be brought together from the front / back of the hand and then joined.
  18. Hi Digibike, vielen Dank für deine Antwort. Ich habe mir den Thread in Ruhe angeschaut. Leider geht es nicht ganz in die Richtung, die ich benötige. Mich würden eher bereits durchgeführte Prüfungen und vor allem deren Ergebnisse interessieren. Z.B. ist die Probe des Kunststoff-Zugversuches genormt, daher ist ein gewisses Maß an Allgemeingültigkeit und VErgleichbarkeit gegeben - zumindest wenn die Proben und deren Druckausführungen beschrieben werden. Leider habe ich in der Richtung immer noch nicht arg viel mehr gefunden. Ich habe die Möglichkeit einige Bauteil- / Werkstoffprüfungen durchzuführen, allerdings ist das sehr aufwendig und diese Arbeit würde ich mir gerne sparen, wenn andere sich diese Mühe schon irgendwann mal gemacht haben. Primär geht es um Vergleichswerte, um eine qualitative Aussage treffen zu können, Auswertungen in Diagrammform wären natürlich ein Traum. Gruß lePierrot
  19. Hi @tinkergnome Thank you so much for clarifying questions that I consider very important for understanding things here. You're absolutely right. At that time there were not so many specific and advanced settings within Slicer. It was certainly a clever idea at the time. Simplifying the user's life. I have a question for you. These days, for users of Ultimaker 2+ or 3d printers using Ultimaker 2 (Ultigcode) flavor, there would be a possibility of not using it anymore. And can it go the same way or shape as the latest 3d printer models? I say this because Slicers' technology is increasingly advanced and feature specific. I think it would be interesting for the user to be able to choose whether to stay in the Ultimaker 2 flavor or the Flavor that is used in the latest 3d printer models. Please correct me if I said something wrong as I am not an advanced user. What do you think? Would it be possible? I thought the firmware would be directly associated with Flavor being used on the machine. Just doubt of a person who does not understand much. How great to know that the two things are unrelated and separate. Thanks for the tip, if I saw this "override settings" message I would think I had done something wrong and I would panic! Thank you so much for explaining this to me. Thank you very much 🙂
  20. Hi there.I´m having some troubles with my last printings and i´ve realised that the printcore 2, even when the lift switch is up, remains lower than printcore 1. Now appears the "Difference between detected height of both PrintCores exceeds realistic values" error. However this is an usual error for me. The problem is that I cannot level the platform cause printcore 2 is always lower than printcore 1 Any ideas? Could it be a problem with the spring? I feel it isn't working well when I do this and the lift switch seems to work fine: I´m using Ultimaker 3 extended Thanks
  21. From the video filename on the Registration page, it looks like this news could involve the existing S5 model and a new product, the Ultimaker S3: http://images.3d.ultimaker.com/Web/UltimakerBV/{c7db3d3b-bb17-430d-8a81-e3b5fb9e635e}_S3_S5_Teaser_(1).mp4 Obviously no details other than a name and a silhouette, but could this be a smaller cousin of the S5? We'll soon see...
  22. He will always be in our hearts 😭
  23. As far as I know the extrusion stepper is not the same, it is step angle 1,8 degrees while the axis motors are 0,9 degrees. And I think it’s worth to recover the printer. Would you buy it used with this „mileage“ but working it would surely still cost 500+ Euros and there would be some maintenance of belts etc required. I am sure you can get it working for less than 500 Euros and a few 10 hours of work.
  24. Why can't you just buy ordinary gloves at any clothing store? They come in many sizes and many materials such as cotton, wool, leather, etc.
  25. UM printers can indeed print that clean. But I was looking at the detail in the print job that made me think of the inkjet 3D printers. That tattoo on the bicep is unbelievably clean. It can be done, but it takes a lot of work to get something like that done by hand.
  26. I really was just asking a far reaching question. I was thinking of the downloaders since I make 99% of my stuff. Yes, I will download some things for modification, but not enough to request something like this. So, I would guess the one that is easiest to implement. 😊
