Have you ever had an issue with filament dust on the metal extruder?
I printed something with silk filament and where the filament fed into the bowden tube, past the extruder gear, some how the filament was getting, I guess the best way to describe it, is “shaved”.
After some research I figured out that the main issue was I wasn’t using a high enough temp for the nozzle (this silk filament needs a higher temp) and there was a pretty major clogging problem. After I got it all cleaned out I put some different filament in and I noticed that where there had been shavings, now there is a fine, filament dust. Is this normal? (Yesterday was the first time using the metal extruder.)
@lisaviolet what temp are you printing at? I’ll get a little dust, but not much. It’s usually if you are printing too cold. You can also hear the extruder skipping if it’s so cold it can’t push it out.
@RiotDemon I usually print at 200°. I guess that wasn’t hot enough for the silk filament, but it works fine for regular, at least I’ve never had a problem with it before.
This is from a piece of the Silk PLA filament. You can see the marks from the gear pressed into the filament, as well as the little piece that was shaved.
I’m redoing the piece in plain black PLA filament at 200°, it’s been going for over ten minutes with no dust at this point (I also have two guides, one at the top and one next to the entrance to the extruder).
Last night I was getting a little black dust in the circled area, but not this morning.
I was just wondering if you’d ever encountered this.
Not printer specific, but this was probably my favourite project downloaded from Thingiverse. It’s a silly little scarab beetle box. It’s got several components which come together into a fun little gewgaw.
This pic is jacked from the maker page on Thingiverse, not the box I actually printed:
@RiotDemon micro center was very disappointing. Everything was all over the place and the few accessories they had did not make sense at this stage. I did buy a roll of pla+ in black for learning. From what i gleaned from internet, one’s filament should be kept clean and dry. It is very humid here right now so I’m thinking I should wait until summer is over.
@lisaviolet@RiotDemon Unfortunately, I do not have a junk room. Its either going in the living room or the guest room. I might actually temporarily repurpose the old microwave cart that I was going to throw away for a stand. Everything is still disrupted by the renovation.
@transplant definitely suggest watching the build video while building. I used fat dragon’s, but the chep one is probably updated a little bit for the newer Enders. I did not use the instructions they sent except to look and make sure nothing major changed. They have changed some minor things, even my machine from last year was slightly updated from the fat Dragon, but the build was mostly the same.
I suggest subscribing to their channels, because they do have a lot of information to help you get started.
@RiotDemon@transplant seconding the fat dragon video. Used it when building my Ender 3 Pro a few weeks ago. There are def some differences between that vid and the pro, but they were minor enough and it still really helped in doing the first tuning and setup.
Mine is built and printing. (I know, I know, it didn’t happen unless there’s a photo…but soon.)
I took my time building it (2 days), but I have arthritis in my hands and sometimes the frustration factor is high, so I paced myself. I watched the suggested videos before and during the build and didn’t really look at the instructions while building. (I did read over them before I started.)
Leveling the bed is key.
I’m learning how to use Cura and Tinkercad. My brain is getting a workout!
Thanks for the pros posting the tips-I’ve bookmarked all of them.
So, any recommendations for accessories? I’m thinking about a glass printing bed…
@transplant I have a glass bed. Came with my printer so I never even used the regular build mat. Upgraded the springs because mine were super sloppy and couldn’t get leveled. Changed to a metal extruder.
If you haven’t printed a filament guide yet, I highly suggest it. I also printed a fan cover for the motherboard case to keep little bits of filament out of it.
@transplant I ended up printing a Y tensioner because I added a drawer to the front of my printer and I could never get the belt tensioned properly after that. I literally quit printing for months because I was so frustrated. I was surprised that I could even get it to print decent enough to work. I suppose I could of bought a metal one, but I persevered.
Makeup organizers. I did the small one first and decided it was way too small. The bigger one took up the entire width of my bed and took more than a day to print. This was the most annoying print because it had what sounded like a million retractions. I don’t have a silent board upgrade and at the time my printer was in my living room, lol.
Mine is now built. The instructions were not super useful. I think I need to redo part of it as I think it looks messy and crummy. The instructions do not show or mention any of the cabling so it ended up with them sort of all over.
@lisaviolet@RiotDemon I was too tired to run down to the pool to re-watch the videos so I figured I’d wing it. Bad words were said. I only stabbed myself with the stabby sharp thing once, though, so I was patting myself on the back. Today, however, I feel as though an elephant stomped all over me. Sitting hunched on the floor is not good.
I’ll have to investigate these clips and drawers. I also think I now know what the rubber tube was for. And the zip ties.
@RiotDemon It was late-ish when I finished. I sat there waving that dumb tube around going “what is this and what am i supposed to do with it!?” I probably should’ve waited until the weekend. Next time.
@lisaviolet@Mehrocco_Mole not always. I follow several different printing groups on reddit and usually the print will be covered with little blobs and most likely it’s the seam set to random… Of course if you calibrate retraction perfectly then the seam is less noticeable anyway.
What is the easiest way to swap filament? The Bowden tube is so long, the first swap I did, I cut it at the gear and then fed the next filament through but it took forever to push by out the old filament
I guess I can’t complain about free videos but they don’t seem to make close-in clear shots of what they are actually doing a priority. And them telling me what they are doing is not very helpful, especially when they are using terms and names that I am unfamiliar with. (I guess I was just complaining.)
@RiotDemon No, its really just me. I just suddenly decided last night that I couldn’t wait any longer and had to get it assembled right then. I’m going to watch a couple of videos today which will help me understand what all those parts were and what I need to do next.
