I'm in.

No issues. It's still as solid at the end of the print as it was at the start. I will admit I took the precaution of using a new spool, but that was also partly because the estimated PVA usage for this one was almost a whole spool. There was still a little left on the spool though and I used that on another print without issue. I think when you're constantly printing with it (like on a long print), you're consistently exposing new PVA, as opposed to having a rolls that's been sitting open for a month or two. I've definitely printed with some marginal PVA in the past--stuff that had been left out a while, but that I thought was still firm enough. On those cases I knew I was taking a chance and sometimes it turned out okay, and other times...time to clean the Core after it either wrapped around the feeder or the filament got brittle in the tube (depending on whether it was left out in an office during winter months with the heater on, or left out in the humidity). I've partly done some prints with PVA that's been exposed to get a better idea of how to recognized when it's gone bad, and when it may still be okay to use but not quite as clean.

We did a 9 day print recently on the Ultimaker S5. I love how this turned out. Admittedly, that tail is so fragile, I'm a little afraid to breathe whenever I walk by it. We've got the S5 set up on a custom rolling cart we built with some built in storage areas. The STL is here: https://www.thingiverse.com/thing:284409

If the feeder casing is white instead of black, you have an Ultimaker 2+. If you accidentally put Ultimaker 2 firmware on an Ultimaker 2+, the feeder will run backwards, because the UM2 uses a knurled feeder instead of a geared one. Update your firmware and you should be all set.

Regarding GST versus GS2...due to changes in the law, I don't believe it's legal to import the GS2 ones anymore (if you're in the US). GST is the new standard for the part.

Hi, Emilio. We have them available here: https://fbrc8.com/collections/ultimaker-2-spare-parts/products/power-adapter-24v-220w Are you in the US? If you're not in the US, you may have another reseller closer, which would save you on shipping costs.

It looks and sounds like the printer was having some issues with the endstop in the corner--it shouldn't grind like that. Since it calculates the home position based on the endstops I think that's where the issue is. Have you done the Limit Switch test in the Diagnostics menu?

Definitely check your printhead shafts like gr5 said, and checking the lifting switch function by hand. Also, if you perform the lifting switch test in the Diagnostics menu, does it work? If not, try doing the liftings switch calibration again following this video:

I haven't tried anything more flexible than the 95A shore hardness. Someone on the Materials board may have and can let you know how it goes: https://community.ultimaker.com/forum/111-materials/ UM3 and UMS5 are both bowden fed (rather than direct drive). Being bowden fed means the printhead can be a lot lighter than a printer with direct drive, but it also means you've got more friction inside the tube, which can be difficult for more flexible materials. TPU95A is pretty flexible, and has profiles built in Cura already.

TPU95A is about as soft as you'll want to print with a bowden fed FDM printer. About what size are the models you're doing? Would you benefit from the larger bed? The S5 does also have some other features (like the flow sensors so you know if you've run out of filament). It all depends on what your needs are.

Hi, Jim, have you reached out to your reseller or the Ultimaker North America support team (it looks like you're in the US)? If the printer's still inside the one year warranty, we should be able to help you out. When you email in, include the serial number of your printer, and a copy of the receipt. Photos of issues always help too.

I actually really like the Proto-Pasta matte PLA. We've got some in stock. We remixed this Julius Caesar bust from Thingiverse a couple weeks ago and printed it with the white Matte Protopasta. I've got a base we did in Bronzefill (still need to find the time to polish it up). But I love how it turned out.

The equivalent fan on your UM3 is the front fan. It should keep the upper part of the print core from getting too hot. If filament hairs get tangled in it, it could stop running.

For support, we send out whatever parts are needed under the warranty (so all OEM parts, no bondtech). It looks like my technichian responded on your support thread after this last post and has some other things to try with you that he wanted to check out.

This isn't related to the feed issues, but make sure you bend your fan shroud back into the right shape. Where it's dangling down on the left, you could snag it on a print and kill a print you've put a lot of time into. How many print hours are on your machine? What's the tension set to on your feeder?

From the third picture, I'd say your rear fan isn't running. This is the fan that should be keeping the hot Teflon piece (and the filament above the nozzle) cool. If it's not running, the filament will expand due to the heat, and it will be too wide to proceed down the Teflon piece, resulting in the grinding you're seeing in picture 2. Your rear fan should be running whenever the nozzle temp is above 50 C. (Or if this an older printer, running whenever the printer is on.)

I think you need a fairly non-stretchy fabric. I think tulle or denim have been used. And then you'd probably want to use some binder clips to secure it to . the glass plate. Beyond that...I bought some fabric to try it out a couple weeks ago and haven't had time yet.

Absolutely. Printers get super hangry.

It's a spot where wear and tear can occur on the lever if the filament isn't quite sitting straight on the bearing; it's not super common but we've seen a few cases. I just put the label on the box actually about 5 minutes ago, and you should have the part in a day or two, with tracking information in your email. There's also an update on your support ticket with assembly instructions for installing it in your feeder.

Glad it worked! Definitely always do a factory reset after a firmware update; it's the best way to make sure all the changes really go through.

Did you do a factory reset after updating your firmware? Sometimes new profiles don't show up after a firmware update unless you factory reset the printer. PP should be fine for a UM2X+. It uses the same feeder as the UM3.

I think the angle of the spring would also make a difference in how well it prints. I've found a couple of files on Thingiverse that look to have printed okay as springs without any support. They're not perfect and would probably benefit from support, but they seem to have printed. https://www.thingiverse.com/thing:487880/makes

It certainly won't be as clean without dissolvable or removable supports, but I wouldn't say you can't print a spring. This isn't quite the same, but pretty similar I think to printing a spring: No supports; I can't remember if this was printed on a UMO or UM2 (back in 2013). No supports. I'm pretty sure it was the UMO, but I'd have to defer to @illuminarti to confirm.

Switching the two Core positions is totally fine; I actually recommend it in a lot of cases during troubleshooting if we're trying to narrow down an issue along one of the feed paths. I'm running a print right now with PVA in Feeder 1 and PLA in Feeder 2 because I'm using Faberdashery PLA (loose coils not on a spool) and it worked out better in my workroom that way.

Glad to help.
