Nice! Did you paint everything? Why not print it in black and red?

Hi @Pieter90, welcome to the forums! I don't think this has anything to do with the filament. Since the shift is so erratic instead of just being skewed I don't think it is an pulley or belt that is causing it, but rather an end stop. Could you check if they all still work properly? Maybe the Y end stop (front) is rubbing against the pulley and that caused some errors during your print? (making it think it is being triggered?)

Looks really good!!!

Probably somewhere in 30-36 hours :(

Ive never had to purposely up the infill for a better surface quality. Dunno if I was blind to improvement but it seemed fine when I found that low sweet spot for printing. Another factor in play could also be material. For example ABS hides irregularities better than PLA. Does anyone have a preferred PLA brand for smoothest surfaces? (could also be just color related..)

Hi @JohnsonK, welcome to the forums! I'm happy to hear you have always been very happy with your Ultimaker. What kind of things have you been printing? It sounds like something got misplaced or put together differently after taking it apart, if it started misbehaving since then. Have you considered using some tweezers to remove the string of filament? Can you check if the setscrew on your teethed sleeve is properly secured? If this is loose, there is no grip on the sleeve and even though the motor might be turning, this movement is not transferred to the sleeve, and your filament will remain still. When the print is running, can you feel the motor work? Does the motor ever work? Looking forward hearing from you!

Hi @RenLDN, Welcome to the forums Have you already tried to level your bed? (Not sure if that is what you mean by Maintenance - Buildplate, just making sure.) What happens when you follow this procedure? Does it seem OK while doing the leveling, but afterwards when you start a print it goes higher? If you could walk us through what is happening, that would probably be helpful. What kind of new extruder / printhead did you install?

Hi, welcome to the forums! I don't think your overhangs are thát bad. There are several things you can do, like print cooler, make sure the angle is aimed towards the fan or print in thinner layers. Not turning on your heated bed can also help, because heat makes filament softer / saggy and therefore the radiation from the bed can also negatively influence overhangse which are relatively low on your print. Printing thinner layers is not always better. A thick layer is heavy and will sag easier, but a thin layer may curl up instead, also leaving its trade on the surface quality. The ear on your robot is probably due to cooling. The cooling is not entirely symmetrical, cause the nozzle is on the left, and therefore the cooling is slightly better on the left.

Have you tried to move the model around? So is it always on the left side of your model, regardless of where it is, or is the irregularity of the infill bound to a certain location on the buildplate? You could also look into slowing down the infill speed. At what speed is that?

No we don't And since you are changing to PIB for some part of the hot end, that is also where the filament passes and makes contact, no? So, some materials go well with others, some react more and create friction. So I was wondering if you suspect to any of these new, high temp materials could create difficulties with PIB, besides the question if it will withstand the temperatures.

It is pretty colorful for a rocking house I can see how stringing could function as some blinds too

oehhhh, exciting! Sound like great test results! What do you think the challenges are? How it will affect the heath break? If there will be any friction in the hot end?

Keep us updated on how this continues, I think it should be interesting for everyone! Hopefully you'll receive the firmware soon so you can start putting it to a test. Thanks!

Are you printing PLA or ABS, and has that always been the same material during the heavy use over the months or did you change between the materials? Did you ever do an Atomic Method?

It has been unflagged, you got an out of jail card

Hi @Gudo, thanks for sharing all this. I think a lot of people are reading about your developments! Your last post dates from a few days ago, wondering if you have made any further progress Looking forward hearing from you!

You should be best off asking @Swordriff

Ultimaker Sessions De volgende meetup staat weer bijna voor de deur, op 25 Juli in Fablab Protospace in Utrect. Dit keer gaan we het hebben over nieuwe materialen, die toegevoegd gaan worden aan ons assortiment aan filamenten. Welke filamenten we gaan bespreken? Dat houden we nog even geheim tot tijdens de Ultimaker Session. Hopelijk kom je langs om te leren welke nieuwe materialen er aan komen, wanneer je voor welk materiaal moet kiezen en hoe je hier het best mee kan printen. Als je dan toch komt, neem dan gelijk jej Ultimaker mee want wij zullen wat samples meenemen zodat je de nieuwe materialen meteen kan proberen! Datum: 25 - 07 - 2016 Locatie: ProtoSpace Utrecht Programma 17.00 - 18.00 Aankomst. Je kan ook eten bestellen als je wil, (10 euro pp, cash or card) 18.30 - 19.00 Presentatie 19.00 - 21.00 3D Printing time! Als je denkt langs te komen, zouden we het op prijs stellen als je even kon RSVP'en via deze link: http://meetu.ps/2XLDRy Tot dan!

I'll probably be there, Marrit and probably some of the other regular faces you know

Ultimaker Sessions Our next meetup is coming up again, on July 25th in Fablab Protospace in Utrecht. We will talk about some new materials that will be added to the Ultimaker range of filaments. Which filaments we will be discussing? That will remain a secret to be revealed during this Ultimaker Session. If you want to try these new filaments, make sure to bring your Ultimaker because we will be bringing samples! Date: 25 - 07 - 2016 Location: ProtoSpace Utrecht Program 17.00 - 18.00 Arrival. You can also order food (10 euro pp, cash or card) 18.30 - 19.00 Presentation 19.00 - 21.00 3D Printing time! We'd appreciate it if you would RSVP using Meetup: http://meetu.ps/2XLDRy Hope to see you there!

So yes.. travel speed Besides that; it is very difficult to capture all the data in a chart. It is submissive to so many values.. It is different for each brand, each color, and even by the size and complexity of your model. By doing more printing you will develop a feel for this and should be able to create quite some reliable results straight from the bat Good luck with your test!

Hi Max, Welcome to the forums! You picked a challenging model to start your 3D printing adventure with What you are seeing on your print is called stringing, and it is only on the inside of your print because it is being dragged along with the printhead during movement. The head doesn't travel outside of the model. Usually stringing happens when there is an imbalance in printing temperature and speed. So I would recommend to print a little bit faster and see how that affects the print. When you significantly increase or decrease either speed or temperature, you should change the other value accordingly. Good luck!

On the 25th or 26th? I think I'll be there on the 26th!

Hi Omar, Welcome to the forums! Feel free to let us know what you think of the Coursera course. I am not entirely sure I know what you mean getting more experienced with the technology. If you want to see one, I suppose you should see if there is a showroom in your area or get in touch with a maker through 3DHubs. 3DHubs might also be an option for you to request some 3D printed parts to develop a feel for them.

Thanks for posting in the forums. I'm sorry to hear you haven't received your Extrusion Upgrade yet, if you have ordered it in late March you should receive it pretty soon. Let me see if I can come up with some more specific information for you. Could you share with me your specific order date and order number too?
