PEI coated spring steel is the best. I have a double-sided one (TwoTrees?) I have to check out for Vine. I'm excited to be able to flip for more/less grip depending on what I'm printing. IIRC, the textured surface is better for PETG.

man in the eyeball hat posted:I am interested in getting an Anycubic Photon Mono X (potentially 6k, depending on how much money I feel like spending). My main concern is finding the right place to set it up, as I live in a two-family building. Nowhere in my main unit is appropriate, but I do have a semi-shared basement with space to possibly set the printer up. The basement is mainly used for storage, and a few days a week I go and lift weights or do laundry down there, otherwise it's unoccupied. I mean it’s not like radon gas or anything, but I also wouldn’t stick my face over a vat of resin and inhale deeply either. Phrozen Aqua 4K doesn’t smell too strong. You’d probably smell the ipa more than the resin (at least my wife does and she has a bionic olfactory sense. What I did over the winter was to get a grow filter and duct and just recirculate the air in my workshop area. That worked really well, though when I change my IPA in the wash station I have to crank up the speed to compensate. Now that it’s not freezing out, I really need to cut a hole to vent it outside. Are you sure there’s no way to vent? What about near where the dryer vents?

I'm looking to get into 3D printing, with the usual recommendation being the Ender 3 V2 I've been shopping around and was just wondering if anyone had experience buying in Canada? Is there any vendors I should avoid at all. I found this one that's steadily dropped in price over time in a potentially sketchy way and there's this one from Amazon that has some freebies. But I have no clue who is trustworthy in this space.

Is there any weird fuckery I need to do between Fusion360 and Chitubox to get accurate dimensions? I have a part I designed in F360 that I know for a fact should fit on my Anycubic Photon build plate, but when I open the STL it towers over the build plate until I manually scale it down. F360 is set to mm units, and when I export the body/3d print/etc I have verified that “mm” is units. If I do a point to point measurement in F360, the part is dimensioned correctly. A specific hole in my part is 65mm diameter as expected. I can start a new design, import my stl with mm units and everything dimensions correctly, so I don’t think that F360 is exporting with incorrect coordinates, and it interprets the coordinates as mm as I would expect. But then when I open the STL in chitubox, the same hole which should be 65mm is now larger than my build plate, obviously incorrectly. I can’t find a way to do a measurement in cbox but it’s very obviously wrong, and more annoyingly I have no idea how it’s interpreting what it’s being fed so I can’t figure out how I would even begin to guess at a proper %age scale reduction to get it to print 1:1 as designed. Any thoughts? I’m open to other slicers, but I feel like there’s something very obvious that I might be overlooking. E: F360 part, diameter 66mm  Export settings, mm  Mesh, re-imported to check (roughly, by eye):  And yet:

Is your F360 file in MM as well? On the left in the tree thing under document properties there's In/MM. I know I've had issues with importing things before that the document itself was in metric but even though I changed the export specifically to imperial it stayed in metric.

Yeah, though I have no indication that this is actually importing in inches. Everything about cithubox says it defaults to mm, f360 swears up and down that it is doing coordinates in mm space, so i'm just at a loss to understand exactly where this is going sideways

Dumb question. I wanted to post pictures with this and I remember taking them but they aren’t on my phone and I’m out of office all week. Oh well. Any suggestions for dealing with very fine strings with PLA? They are almost Spiderweb or cotton candy like. They mostly seem to happen when the head is done with supports. If I print without supports its usually a little cleaner. I’m also noticing some minor zits on some spots where specific geometry is ending the path perpendicular to the main geometry… if that makes any sense. I’m on a GCreate GMax2 - the hot end assembly is basically an E3D Chimera with upgraded heaters. I’m fine tuning the factory settings for it in PrusaSlicer. I’m printing usually with Atomic or Matterhackers Pro PLA at 205 degrees. Previously I’ve found lowering the temperature helps - around 195 does better. I’ve messed with retraction - doubling the default config from .75mm to 1.5mm, but I didn’t see a huge difference.

RabbitWizard posted:"Hot air rework station" is different from "heat gun" Orient it the same as the first picture. No supports. It's a...16ish...hour print. I printed it with 20% infill and it seem like it didn't use a lot. I am going to print another with a denser infill. This one feels a little brittle Edit: I have to get me one of those PEI steel plates. Transparent PETG might as well be super glue.

mattfl posted:I've got a bad thermistor wire on my Voron and I'm going to have to tear apart all the stupid cable chains to replace it, this is going to annoy me. Yeah, I had this happen on my Ender - don't have chains but one of the sleeves that I assume came with it. I wasn't 100% sure it was the thermistor so I just left it taped to the outside of the main bundle of wires to test (seemed to fix the thermal runaway errors). I still kept getting clogs and stuff so decided to change the nozzle. I preheated the hotend to 185 before I did but it still rounded the nozzle off with the dinky little spanner, then I sheared the jerk off with my locking pliers. My new hotend just arrived tonight so going to try and swap that in over the weekend and hopefully she'll be right. All these issues are really bumming me out, has stalled a few related DIY projects.

I have had issues like that importing things into Lychee (especially if it comes from someone else), so it's not impossible people may run into this. It's easy enough to just change the XYZ scale in your slicer to the proper size in mm, and then export it as another STL.

Oh, right, and I got my stuff for extending the print height delivered this morning. The aluminum profiles from the Ender3 are already 400mm, and a 2-pack of 800mm ones was kinda the best option. Leadscrew is only 600mm (700mm are way more expensive because of package size), but having so much space above the x-Axis I can use the whole length and get a print height of 500mm.I have no idea what to do with it yet but I'm kinda glad I didn't go for 350mm or something because that was a pain in the rear end and I wouldn't do it a second time. The holes in the profiles were too large to cut M5 threads, so I had to use M6 which means bigger screws which means drilling bigger holes to fit the screwheads. Then you realize that there's a small bevel in the current profiles where the wheels go and the new profiles have way smaller ones so a pipewrench and a hammer are now "3d printing tools". Did you know that there doesn't seem to be a G-Code to tell your printer the new height it can use? You have to compile the firmware for that. I guessed it'll take 2 hours when I started, it took 7.

Slowly getting my printer table built how I want it, got the pexiglass installed now and sealed, going to work on finishing the door up this weekend and my chamber for 8+ rolls of filament to feed my mosiac will be complete. Been a hell of a journey, will post some pics once I finish it up. Built a custom passthrough with an aluminum plate for the filament feeds. Need to find a largish amount of bowden tubing, though to finish up that part. Most places seem to sell 3ft for stupid prices though. On a random note, I did manage to print up some replacement pieces for my grandmothers walker that seem to be holding up well. The deck destroyed the old ones. Just glad to see my modeling is slowly getting better to be able to pull off a functional print that fit and worked in one print. I am sure my prusa is to thank too.

I remember a Prusa blog post that went into a lot of detail about this. The short version is that you can print direct onto fabric, or you can print onto parchment paper / baking paper and make an iron-on. The only two filaments worth trying are PLA and TPU/TPEE. https://blog.prusa3d.com/how-to-print-on-t-shirts_55588/ I remember the main takeaways were: - Flexible filament printed directly on the fabric was very durable (and permanent, not coming off without tearing the fabric.) - PLA worked surprisingly well (either as an iron-on, or direct) but is not as permanent or durable. Looks surprisingly good, though.

Prusa XL with the 5 print heads ought to be interesting. 14.5" is wider than 95% of T-shirt prints, and 5 colors makes you pretty competitive with most silk screen shops. One person could probably run 5-7 machines at a time giving you ~30-40 prints an hour

Deviant posted:The cricut app works great if you can get over how rear end backwards its workflow is though Well, first, it wouldn't start until I updated the app. But there's no newer app in the store. This was only after I logged in, however, no notice about running an old version at startup. Then I switched to my Chromebook to run it, and it started a job, but died because the Bluetooth connection dropped. I managed to get it going the third time, and it does a good job, but it seems like it's just a CNC machine with some proprietary control language that ties me to this dumb software which tries at very opportunity to get me to buy something. Like, you have to go select "please show me the stuff I've been working on" at startup because it defaults to "look at all the junk you could buy". In short, I don't like it, and want to try something else. I seem to recall somebody had hacked their cricut to use a new firmware or controller that accepted gcode. That might be an option, if I can find something to output gcode for a CNC cutter.

I also found a whole mess of Ender 3 hacks, as was mentioned, but it seems like the Cricut is purpose-built for this task and is probably going to do a better job. AFAICT it's just a 3-axis CNC machine with a spring on the Z axis for increasing pressure, so you would think it wouldn't be too difficult to drive it. And inkscape apparently already has a plugin for outputting CNC gcode. This is great because I totally needed a 15th hobby project right now.
