  1. I haven't been here for a while. I just wanted to post a thank you for this link. I was getting severe slipping on the y-axis, but only with some prints. I had checked all the accessible pulleys, I couldn't reach the ones on the motor itself. The main thing that made the difference was that gem about using homing the print head and seeing if I can move it. I could! Without that certainty I'd have been reluctant to start taking things apart to reach the motor. And, so far it is printing perfectly - after about 6 failed attempts. On the bright side - I tuned a lot of things trying to debug
  2. Since everyone comments on it, I guess I must be unique in being quite happy with the old fan noise. It tells me that I've left the printer turned on!
  3. Yep, I have to agree that I don't recognize this claim. If we are talking about the forums then if anything it's IME ColorFabb and Faberdashery filaments that get the most talk. I don't recall anybody ever touting the UM filament even though the quality is acknowledged to be good for the most part. Then again I don't read every post so a link would be useful.
  4. Or just feed in more filament before you release the catch on the feeder? I have yet to fit my feeder upgrade, which may explain why I'm still struggling to imagine what the problem is.
  5. Jeez. Some people are never satisifed. Seriously folks, many other consumer level 3D printing companies force you to use their branded filament cartridge system, so they have you over a barrel. With Ultimaker, if you don't like UM prices you are free to shop elsewhere!
  6. Speaking for no-one else, I have to say that I don't understand. Are you saying that you snapped the filament? Or are you just saying that the filament doesn't come all the way out? If this is it then I expect it's by design: push the release lever on the new style feeder and pull the filament out, which should happen easily. Try to keep the filament reel from unravelling.
  7. I just wanted to say that I'm in the UK, and I received the upgrade kit this week (Thursday I think). I'm posting this to assure fellow UK users that kits are being shipped by the official distributor (3dgbire). I think I made the order around the beginning of March, they were quite clear that there was going to be a wait - and I didn't mind because I have a lot of other projects occupying my time.
  8. I had to work on other things for a few months, but when I started visiting again recently I was pleased to see that the new forum is greatly improved. Information density is, in most places, back up to where it needed to be to be useful. Except in one place that I've found: when viewing my own posts, e.g. when trying to find an old conversation when I can't remember the exact forum section or topic title. I go to my profile and view my "list" of posts... and it's still using one huge tile per post. It's really rather ridiculous that I have this huge 26"/65cm widescreen monitor, but I can onl
  9. Um.. why shouldn't the rods through the head be oiled? I've already given all the rods a drip or two of sewing machine oil in a bid to cure the squeaks (with little if any success) - and that included the two rods you mention. There was no effect good or bad that I noticed. Is this a temperature concern perhaps? If so I'll watch out, but nothing alarming happened, e.g. no smoke. ps. I have the UM2+ upgrade on order, so I expect I'll soon be replacing the head and its rods anyway.
  10. Hi George. I thought I'd provide some closure on this. It has taken me a long time to get around to it, but a couple of months ago I ordered a screwdriver type hex bit set (with ball ends), and this weekend I finally got around to trying it! The problem turned out to be (I think) a spacer tube on the end of the rod that stops the rod sliding too far and falling out of its bearing! This spacer had been knocked out of position when I had my accident. I was able to loosen a few grubscrews, push everything back and tighten it all up again. I tried making myself a couple of little clip-on jigs to
  11. If you're going to do it right away then I really wouldn't put the old feeder back: while some may struggle along with it, there are better designs which mean you don't have to struggle. The one I use is this variant on Robert's design :- https://www.youmagine.com/designs/yet-another-ultimaker-2-feeder I like this because it ensures that the filament is straightened out before it enters the feeder. I also add a clamshell type sponge holder that wraps around the filament and cleans off any dust from the filament (and optionally lubricates) before entry into the feeder.
  12. Be very careful about taking the bolts out - you will indeed hear something drop down inside the printer, because the stepper that drives the filament is held on by those same bolts! Be careful too about the contents of the feeder case - things will drop out of there too. Don't panic, you'll work out how to put it back together. In the past I would have recommended replacing the hopeless stock UM2 feeder with Robert's one, but if you have the UM2+ upgrade kit on order then that's maybe not worthwhile. Basically, grinding happens when the pressure required to push the filament is greater tha
  13. I guess you're saying that my concern about cleaning may be misplaced because there won't be grinding debris, right? You have a good point there.
  14. I do my printing in a small boxroom, and I've never noticed a PLA smell. There might be a warm ozone smell similar to a photocopier or laser printer. Though actually that might just be the film of PVA glue I have on the hot buildplate!
  15. "Releasing the filament" isn't the same as "making it easy to change the filament"! In Robert's design one half of the feeder swings aside, allowing room for my fingers to get in there and coax a filament where I want it to go, before closing it all up again. So the whole design makes it easy to change filament, I wasn't just talking only about a pressure release. And there's the issue of debris collecting inside. Another fatal flaw in the old feeder is that if you took the cover off to clean the inside, the stepper fell off the back, and the feeder bits dropped off the front. Then you neede
