Sagebrush posted:Why does Creality not simply clone the MK3S exactly? It would be a lovely move, but all the parts are up in their site for free download, and surely they could do it for much less than 750 dollars since they aren't spending any money on R&D. That would sure shut up all us Prusa people. Many companies did. They don't anymore, instead having newer designs on sale. Beyond that, there is no answer to your question that does not invoke the religious zeal of the faithful.

You're thinking of the MK1 and MK2, but yes. If anybody has cloned the MK3S with anything like a reasonable approximation of quality, somebody should have posted an Alibaba link by now or something.

Acid Reflux posted:You're welcome! We all have/had to learn this stuff at some point, and we all know that the only two ways to learn are by either asking questions or breaking something really important. I'm glad I looked this thread up, lots of good information to gleam. I had just been watching youtube videos mostly to teach myself! Lately, I've also had an issue with the generic raspi cam I got for octoprint. I can't seem to get it to run anything higher than 480p without serious lag. I'm starting to think it's just the camera: https://www.ebay.com/itm/203627947735?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 The lens probably isn't a huge help for this application either. I've tried messing with so many settings in octopi.txt and have given up and just set it on 5fps to reduce network load. Using with a raspi4. Tempted to buy this 10 dollar arducam that's on amazon. What cameras are you guys using and is anyone able to get a 1080 or 720 stream working over wifi, or is that too taxing on most routers?

Ethics_Gradient posted:Hmm, so I went into the auto leveling function - there's something called "BabyStep" that incrementally lets you raise/lower the printer head. I did this and got to -13.0mm before a piece of paper got pretty grabby, so entered -13.0mm into the Z offset function (also in the auto leveling menu). It kind of sounds to me like you need to readjust your Z endstop. -13mm offset seems really huge https://www.youtube.com/watch?v=bGGNlHkuLX4 Can't find the video I originally used I think it was from bv3d, but this should have the information if you're not familiar with the process. Oh right... you're using auto leveling so the z endstop is removed, my bad! Did you correctly set your probe offset too? Opinionated fucked around with this message at 04:00 on Dec 29, 2021 |

What's the easiest way to smooth out a petg print for spray painting? I really do not feel like sanding this thing flat, so some epoxy or filler primer I'm guessing?

Maybe try your hand at careful passes with a heat gun until you get the result you want, but that can rapidly get out of hand if you soak too much heat in one spot.

oh yeah, you'd need to be an artisan with a heat gun to get PETG smooth. I managed to bend a pretty stout piece because it just soaked up the heat much faster than I expected. Maybe if you had a well controlled reflow heat gun? You could "sous vide" a piece just below the plastic melt temp and work it with a spatula?

Sanding is the only way to do it. Sure, you can spray it with high-build primer or something, but you'll still be sanding that. The coatings like XTC-3D kinda work, but as a thick epoxy clearcoat, they change the part's dimensions fairly dramatically. Maybe that matters, maybe not. Heating the print's surface to melt it will not work. Too hard to control, too much diffusion. If you want effective easy print smoothing, you need to print in ABS and use acetone vapor techniques.

From my quick testing, I think I'd greatly prefer sanding spot filler/primer to petg, it seems really.. hard. It's the outer face of my 10" ring, I'll see if I can find someone who can do that in abs as I do want to make a change.

where is the website that has all the ways a benchy can go wrong with its recommended settings. ? Trying to use up some old PETG (seems dry) and getting oddness i have never seen before : I need to tune retraction but this looks like it lost its poo poo a few layers in .... part cooling kicking in? I have it set very low but maybe the 5010 makes it much more efficient ? It freaks me out i get poo poo layers, then i have whole sections smooth as butter. My calibration cube was excellent

Smoothing out FDM prints always sucks always forever always. Two coats of filler primer, a light sand, another coat of filler primer. If that isn't smooth enough, you're not gonna get it smooth.

Minwax wood putty works very well on pla, you need about half as much hardener as the instructions say, at room temperature. Also it is much easier to sand in the first three hours. Don't let it cure indoors in an unventilated space (like your bedroom in the winter) it puts off a lot of fumes

I don't know the quality of the cloned Einsy, but the rest of the parts are going to be drat near 1:1 with Prusa's quality (if not from the same OEM -- RUNICE). I will grant that shipping's pretty steep (and I didn't catch that), but even then $600 shipped with the mainboard is cheaper than $800 shipped for the Prusa.

Hey all. Been printing about a year and a half or so on an ender 3 and had the hotend nozzle thread partially strip, enough to warrant a replacement. Ordered and replaced with another oem, wiring as well which was very straightforward. Once reassembled it emits the loudest, most constant alarm it can manage. Screen starts booting as normal, but that's about how far I get before I have to switch ot back off. All connections checked over with same results. It's not the thermal runaway alarm either, that one has a rapid ramp up to a constant tone. This one is just on from the start. Getting a lot of results linking it to a BSoD but I'm not having that. Any thoughts as to where I should start my investigation? Printer is basically stock with the exception of the extruder.

Combat Pretzel posted:Step files would require slicer developers to adopt a geometric kernel for conversion into polys. And these are considered voodoo code. No, STEP is a NURBS format. You are correct that it's vastly more complicated to process a NURBS model than a triangle mesh. And unless the slicer developer is going to try to implement some form of NURBS editing (which is far more complicated than just viewing the geometry), you're just going to immediately triangulate it for slicing anyway. So for most people the only advantage of importing STEP files is that they could choose the triangulation resolution, which doesn't give you any benefit over a properly exported STL. I agree that I would like STEP files of printable mechanical parts to be made available alongside the STLs, because it's much easier to do precision editing of the geometry if that is required. Also, just a comment on terminology: parametric modeling is the technique where everything in your design is driven by dimensions and relations. A STEP file contains mathematical spline-based geometry called NURBS surfaces. While most parametric modelers create NURBS surfaces, it's not a requirement that they do. SolidWorks, Creo, Unigraphics, Inventor, Fusion (in some modes) and CATIA are all parametric NURBS modelers. Rhino and Alias are freeform (non-parametric) NURBS modelers. Blender, 3ds Max, ZBrush, Cinema 4D, etc are all freeform polygon modelers. OpenSCAD is a parametric polygon modeler (and the only one I'm aware of).

They are all pretty "fast" though: green is 1.5 min working (15 dry) and white is 2.5 mins (20 or 25 dry) or something. So any of the three colors (green, red, white) is probably more or less the same -- but for 3d printing stuff I'd prefer more working time personally.
