Going back a page, I've had my Ender 3 V2 for nearly 2 years now. It's completely unmodified, everything is exactly as it came in the box. I have not had a single issue with it. It's printed everything I've thrown at it. Nothing has broken or needed replaced. Auto leveling would be nice but even then I only ever seem to need to do that once a month or so. It's been an absolute workhorse with day long prints. I think I must have gotten lucky because if it were not for comments in here, I would absolutely recommend people get one as an entry to 3D printing. One other thing I did appreciate was having to build the thing in the first place. It meant that I got to learn what each part was and what it does as I was building it.

As I say, I guess I am just really lucky. I've been observing it regularly as I was told that it's one of the things that will fail and there's no sign of wear on it. My only "modification" I've done is that I bought a set of different sized nozzles. Even then, I'm pretty sure the one I have attached right now is the one that came with the machine.

Macichne Leainig posted:I'm not saying you don't have thermistor problems but if you haven't solved your overextrusion you're gonna be fighting that problem probably just as much as the thermistor issues. Right, so, last night I calibrated the extruder, using that Voron guy's technique. I told it to extrude 100mm at an excruciatingly slow speed, and got 94, 93, and 93mm out. So I changed M92 E380 to M92 E408, and now I'm getting 100mm out when I call for 100mm. Telling the extruder to go faster didn't seem like it would help with the overextrusion problem. I printed a test cube to be sure, and, yeah, it's still overextruding. I hunted all over PrusaSlicer for things that might go into calculating the extrusion speed, and all I found, aside from the magical "extrusion multiplier", was filament density and diameter. Using my $2 plastic calipers (fancypants calipers are in the mail), I'm seeing the diameter is 1.75mm. So I'm going to set the extrusion multiplier to 1.0 and twiddle the density until a test cube looks right, FOR SCIENCE  I'm also going to completely blow away my PrusaSlicer configuration files, start from scratch, and see if I possibly introduced some weirdness that I forgot about. It wouldn't be the first time I'd done this with software. Lastly, I'm going to do some reading, possibly through source code, to determine exactly how extrusion is calculated by the slicer. It seems like it will use layer height, filament density, and filament diameter to calculate, then multiply that by your extrusion multiplier. Am I missing anything? e: yes, I was missing extrusion width. And before someone else tells me to just call support: I'm having fun, quit telling me how to live my life, dad. cruft fucked around with this message at 17:38 on Nov 29, 2023 |

The extruder calibration gives you a known starting point to build on with later config, so you're right that extruding more filament doesn't solve your overextrusion, but now you at least know that it's extruding what you tell it to. If you run calibration tests now you'll find that you'll need to tweak the extrusion multiplier (potentially individually, for different filaments) to get optimal results.

I read some more stuff, and I bet somebody else ITT doesn't know this, so I'm posting again. The slicer only uses filament diameter and extrusion multiplier to calculate extrusion. Well, and extrusion width, but that's a per-print setting that presumably you want to change to do different per-print tweaks, not something you want to mess with to adjust the overall extrusion. Filament density is only used to display how much filament a print will use, in grams. Having tuned the E steps so that the "extrude 100mm of filament" instruction results in exactly 100mm of filament being extruded, the only lever you can pull to further account for filament extrusion differences is the extrusion multiplier. That's nice for usability: I just twiddle this number until it works right. I can just not worry about all the various physical properties of the filament, and turn this knob until it comes out right. I'm guessing people who do a lot of printing will spend some up-front time building an extrusion multiplier for each roll of filament, maybe even re-calibrating mid-roll for manufacturing differences. The slicer lets you store individual filament profiles, with color, and, to my surprise, I've created a filament profile for this one spool. I imagine I'll eventually have a profile for every spool I own. In summary: Yeah, Ellis' Print Tuning Guide was a good call.

It isn't possible for filament to be tangled as it comes off the line. There is just no physical way in the manufacturing process that the filament can loop underneath itself while spooling. I suppose it is possible that your spool got dropped and uncoiled at the factory before it was wrapped up and then someone got it tangled when respooling it by hand.

A tangle is where the end of the filament has slipped underneath a loop. This could happen to broken filament, or just letting go of the free end while manipulating the spool during loading or unloading. Ordered or not, it's impossible for a tangle to form while winding, though the person unloading the winder could mess up and let go of the end causing a tangle, though that could happen on an orderly wound spool just as easily. Unordered spools are more common, though the orderly ones are gaining. People just like how they look.

Dealing with resin isnt bad as long as you have the space and knowledge basically. I can get by with just a large plastic tub to contain all my resin workspace next to my printer in a ventilated area, plus mask and gloves. Keeps all the splashing enclosed and I can just cover it when it's not in use.

Keeps all the splashing enclosed and I can just cover it when it's not in use. I was actually just coming in hoping for a quick answer re: resin fumes. I used to have an Ender 3 that I built a LACK enclosure around and printed ABS pretty much exclusively. I didn't properly seal the sides, so just ran it downstairs in my old flat overnight with a standalone HEPA filter on and never had any issues (well, did still smell kinda like burning Hungry Jacks toys if I came down to use the toilet in the middle of the night). I've since sold the Ender (good riddance) and moved to the US, and am currently eyeing a Saturn 4k with new LCD on marketplace for $95 - resin printing suits my next project a lot better than FDM. My concern is ventillation: this flat does have windows I can safely open (last one had no screens, so was worried cat might find a way outdoors), but being Denver it's pretty cold right now, which I imagine might affect my prints? I'd originally been thinking a big upside down plastic tub over the enclosure with some 4" ducting run outside through a plywood cover I'd put over the window when printing - would omitting the inline fan and just letting passive air exchange do its thing work? Handling and cleaning up the resin itself don't bother me that much, I do wet plate collodion (1850s photo process) so am used to dealing with spicy chemicals, but mostly don't want to make my living space inhospitable to human/feline life.

I probably could have put in a roll with cardboard in the AMS, or switched to another color, but I was hardheaded. I printed a slightly different one, but it rerolled some of the filament really easily and was worth it. The clearance on some of the bearing was tighter than what the assembly video showed… or I’m just really weak.

Ethics_Gradient posted:I was actually just coming in hoping for a quick answer re: resin fumes. I would opt for the inline fan. I don't know the MSDS on resin fumes, I believe it's been posted here before in the past, but I just work on the assumption that it's best gotten rid off. I have an inline fan and a DIY fume-hood setup to handle it with negative pressure, and always suggest something similar. The stuff isn't going to melt your face off or give you turbo rear end cancer in .03 seconds of exposure, but it isn't something I'd be bathing in on purpose, ya know? Nail salons have been using UV-cured resin for decades now. The chemistry of it isn't an exotic thing nobody has ever seen before with no idea how to manage it, but precautions should be taken. I have PPE procedures in my home for the crafting room if I'm dealing with resin. Once that lid is off, nobody is allowed in the room without a face guard and long sleeves/pants. Is that overkill? Yeah, probably. It's also really simple to do and can prevent worst case scenarios. Once I'm done and put that lid back on though, the room is just treated like normal. Cats and young'ns come and go. Hell their litter box is in the room, as long as I'm not actively pouring resin it's treated normally. Also, yes, resin temperature will affect your prints. Resin does not like to be printed cold, herein defined as "less than room temperature" and honestly heating resin up a bit beyond room temperature can be a good idea if temperature is even a possible concern in the working space. If the working space is not being heated many people will use a vat band from home beer brewing kits, and there is even a growing mini-industry of purpose built vat heaters for a lot of the major models.

PLA likes cool air yes, but the aux fan on the X1C is an real warp-inducer in my experience. With PLA I'll only ever flip it on manually for things that might benefit from it... once the print has gotten a few cm in. Early on after I had it installed (X1 comes sans-aux fan), I suddenly got some warping on most larger things... until I flipped it off, or dropped it down to 10-20% just to circulate the air. It's great when you're printing quick, short layers that need the additional cooling instead of slowing down, but with big stuff it's not super useful.

PLA warps on the cool plate for me. Anything bigger than a 2x2" footprint and it's going to be noticeable. I just stopped using the cool plate for anything bigger and keep it only for small parts. The high temp PEI plates (either smooth or textured) are my go-to plates for that reason.

I just stopped using the cool plate for anything bigger and keep it only for small parts. Is the high temp smooth plate an add-on? or is that the engineering plate on the reverse side of the cool plate? I'll have to try the texture plate again without the aux or chamber fan too, because it definitely warped on the aux fan side more and so i think it's an overcooling issue.
