I have never used a 3d printer. But have done a little research.

Be great if someone could confirm my intention is sane.

I have loads of Linux experience so my plans relate to open source all the way.

First off I am brassic(poor). So looking cheap all the way. My brother and I have a tiny narrowboat we are refitting. And plan to use the printer for stuff within the boat.

Due to this printing PA6 to go in the bilge is important. (Diesel and water bad for most other plastics)

As we are both vision impaired and old. The idea is most of the electrical mountings etc will be self designed and painted to make future access quick and easy with our rapidly worsening vision.

So my plan. I am looking at a elegoo Neptune 4 pro.

Because it is cheap but great value. Uses kipper. And seems easy to modify as I grow in use. Also supports temps needed for PA6 etc.

But I will need an enclosure to work with PA 6 and a dryer.

Dryer is cheap not an issue.

But I'm thinking of a tent enclosure. Some good well insulated ones on amazon for £50 with hose to vent out smells.

Will one of these tents be suitable for keeping temperature stable while printing PA6. And can anyone offer other advice for cheap solutions to make this easy.

On a related novice front.

Gue to the vision. One of the projects is to print mounting boards for din rail fuses etc. The idea being to mix colours.

Ie flat surface faces from and back in white. The the inner support fram in a bright colour. This will mean holes to support thumb screws etc for easy low vision future maintainance. IE easy to find the pre set screw holes.

This plan means I can swap colours when printing layers so should be easy without over (for me) briced multi head printer.

But can anyone share experience with doing this with nylon. IE how dose delays in printing the layers while swapping filament t effect the linking of those layers.

As I say complete novice o the actual doing this so any advice will be helpful.

I’m looking for some advice on how to bond a post-processed resin printed piece to a large PLA print. I assume my options are either superglue or maybe brushing resin onto the PLA, attaching the resin print, and hitting it with a UV light?

Is there a better way? Thanks!

Very nice practical example of printed test jigs for PCB assembly testing. Newpipe is down ATM, so if you're looking for something to watch, this might burn 32 minutes. I found it mildly inspirational to get making/designing some stuff again.

Openscad wanted about 25 gig of RAM to crunch this.

Hi everyone,

I'm having a weird issue with text such as the one in this image. Big or small, fancy or regular, all text comes out looking like it does in the image - cracked and hollow. I've spent the last few days trying to figure out why, and I'm stumped.

I've tried printing slower and slower and adding more and more top layers (the bottom 2 bottle caps are completely solid with 100% infil), but it doesn't seem to fix the issue.

Here's what I'm working with:

• Ender 3
  • Software 2.0.8.27
  • Hardware 4.2.2
• CR Touch
• PrusaSlicer 2.8.0
• MakerBot PLA Filament
• I've used various temperatures and speeds. All of them have generated the terrible text you see here

Thanks in advanced for the help!

Update: We seem to be getting somewhere!

The top 2 are the same ones featured in the post above. The bottom left was printed at 110% extrusion and normal speed. The bottom right was printed at 110% extrusion and a much slower speed for the text, and it looks much better! I'm printing another now with higher bridge flow rate (it was 70%, I set it to 85%), so I'll update again in a few minutes when that finishes!

Thanks for the information about calibrating e steps from everyone! It's getting late, so I don't want to mess around with that tonight, but I'll give it a shot tomorrow!

Update 2: welp.

That's possibly the worst one yet. I'm reprinting the bigger insert piece seen in the original post to check if my printer simply can't do that quality or if it's the e steps. If it's e steps, I'm going to bed...

Update 3:

Welp, seems like it's the e-step. However, it's too late for me to care about that right now, so I'm going to bed. Thanks for the help everyone! I'll work on fixing the issue tomorrow

I would really appreciate it if someone could help me with this. I'm having an issue with my Sovol SV06, which is that I get a lot of stringing. I'm still fairly new to 3D printing, so I have no idea what could cause this and how I could go about fixing this. I already searched for this issue online btw but didn't really find anything helpful.

The only change I made to this printer is that I hooked up a Raspberry Pi 4 to it and installed Klipper and Octoprint. I'm also using PrusaSlicer with the config from here.

Edit: Forgot to mention I was using PLA for this print

This was my very first 3D print on an Anycubic Photon D2. Turned out much better than I expected

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

Watch the BusKill Explainer Video for more info youtube.com/v/qPwyoD_cQR4

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

What is DEF CON?

DEF CON is a yearly hacker conference in Las Vegas, USA.

Talk Description

BusKill is a Dead Man Switch triggered when a magnetic breakaway is tripped, severing a USB connection. I’ve written OpenSCAD code that creates a 3D printable file for plastic parts needed to create the magnetic breakaway. Should anyone need to adjust this design for variations of components, the code is parameterized allowing for easy customization. To assemble a BusKill Dead Man Switch cord you will need:

1. a usb-a extension cord,
2. a usb hard drive capable of being attached to a carabiner,
3. a carabiner,
4. the plastic pieces in this file,
5. a usb female port,
6. a usb male,
7. 4 magnets,
8. 4 pogo pins,
9. 4 pogo receptors,
10. wire,
11. 8 screws,
12. and BusKill software.

By attending DEF CON, I hope to make connections and find collaborators. I hope during the demo labs to find people who will bring fresh ideas to the project to make it more effective.

I'm looking to buy ups as I have few power outage (last between 1 to 5 seconds max) where I live but I have never used one so don't know what specs should I check for

Ideally I will plug my 3d printer (about 100-160w when printing), a pi 4 with nvme drive (no idea of wattage) and a mini pc with n100 processor (around 10-20W)

Thanks for your advices

Screenshots of the UI changes on the Mac - in my opinion it is now just wasting a lot of screen estate for zero benefit.

On non-Macs they're adding an extra usability issue by hiding the top menu bar. I've gove back to 2.7.4 for now - fortunately I had my configuration in git.

Up to 2.7.4:

2.8.4:

Seems neat. If it wasn't so expensive, I'd try it.

Side note: I wanna know more about that inline filament dryer. I don't like the prep by using a box. I always forget.

I guess they're just going to end up being really good but heavily overpriced like the rest of the FormLabs products.

Oh boy, here I go shillin' again.

I just updated my 3D printable balisong utility knife so hard that it wound up with a new name.

As usual, you get the brief version here. Massive amounts of details are located, as ever, in the original post and also at the Printables link.

Want one? Of course you do. Get the files here.

Hello!

So I decided, as a way to improve my cad skills, that I would take an old laptop of mine and design a case around the motherboard and use it as a micro PC in my work area. I have nearly all of it designed, just shy of the power button.

On account of not having a sautering iron, I would rather avoid sautering a button on and was trying to go a more analogue approach by printing a button into the case that could maybe use a compliant mechanism to press in and come back out, but I am very uncertain how to go about it.

Any help appreciated

Super simple prototype but if it works... Very cool idea!

Hey. A couple weeks ago I got my old ender 3 pro out of the basement and have been trying to get a decent print with it ever since. I managed to print out one benchy without issue, but ever since then every print I do would be plagued with awful underextrusion.

I've replaced a few parts, including the hot end and the nozzle, and even did this one hack someone suggested where you put a piece of PTFE tubing in the hotend, but no matter what the issue persists. My thought was it might be the creality filament I ordered, so I ordered a spool of hatchbox filament. But the problem ended up being worse on the hatchbox filament. I've put both in a filament dehydrator but it's made no difference. Both spools have tough sections along them that don't seem to melt as easily when I pull them out of the extruder, so I'm thinking that might have something to do with it.

Turning the print speed down and increasing the flow and temperature yielded better results, but it was still underextruding on every other layer.

I want to know if there's something I can or should do before I just give in and buy another roll of filament. I've probably spent enough at this point to buy a better printer, but I guess that's sunk cost for ya.

Edit: SOLVED! I just forgot to tighten the extruder tension arm, now it's working perfectly. Thanks to @[email protected]

I have to have that spider mech.

As usual, since I already wrote a monumental piece on this in the other community, I'm just going to give you guys the short version. The long version is in the cross-post link above.

What it is: A 3D printable Axis lock folding knife, mechanically complete fully functional, with Penguin beak wave opener, one each. The world's finest; the world's only.

Jooooooin usssssss. You know you want to.

I am not a design draftsman, I'm not an engineer. My workflow is usually: I put something on the scanner, load the calibrated scan, trace the outline, throw a few sketches on various planes in there, round a few edges, print it and I'm done.

Fusion 360 scratches that itch very well but requires me to keep a Windows VM and also their free model felt more and more unusable. OnShape is a nice substitute that works fine for me, but I don't like the "free or 1500€/year" approach. Without a middle ground subscription for makers it feels that I could lose anything the second their energy prices for servers go up or something.

The list of CAD software is exhaustive, so I am looking for recommendations that fit my "eh, click, click, click, good enough" workflow. FreeCAD is way too unintiuitive for that. I have tried getting into it, but 3D printing is a tool for me and the learning curve quickly made using it another hobby.

So. Suggestions welcome. Scalding criticism about my lack of enthusiasm and consumer mentality not so much, but I guess that comes bundled with useful advice, so, eh, I'll take it.

I've been trying to troubleshoot a surface texturing issue for several weeks. I accidentally noticed the pulley had wobble, but thought it was the stepper motor at first. Nope. It's the pulley.

I'm interested in trying to build a Snappy v3
