sigh

Here we go. Warm was nice while it lasted.

My first winter here was really shocking. Went from -5 being a very cold winter day in Vancouver to -40 a couple weeks later in Calgary, and suddenly understood how people freeze to death. I'd never been in temperatures like that before, where you had to bundle up to not die, rather than just be comfortable.

Initially, I was still just wearing an old leather jacket, because I don't care if I'm cold briefly between house and car, then car and work... But coworkers pointed out, "What happens if your car breaks down on the side of the road?"

Printing parts for my new printer in bulk now! Gonna be a while though, need about 110 hours worth of printing parts in total.

Thanks for the link! Keep us posted.

While I was enabling the Windows Subsystem For Linux (which gives you a BASH command shell that can run Linux software natively in Windows) I noticed that you can enable native NFS support in Windows 10.

Despite everything people say about Windows 10, just look at that sentence.

NFS support AND full, native Linux command line tool usage in Windows 10.

I honestly think "Donald Trump won the 2016 American Presidential Election" is perfectly reasonable in comparison.

Early versions of the Monoprice Select Mini had a problem with temperature control, and a fairly inaccurate PID auto adjusting algorithm. I haven't done that (run the automatic calibration), this is how tight the newer Select Mini's hold temperature on the bed and hot end. Roughly +/- 0.2C on the hot end, and +/- 0.5C on the bed. Could never tell before how close it was, as the printer itself and Cura both only showed temperatures as an integer.

Gotta say, I'm really, really impressed by that.

Also: +OctoPrint is awesome. I've subscribed to the author's Patreon, because software this great totally deserves support. Nice to have a good use for those old Raspberry Pi's that have been keeping my Random Stuff drawers warm.

Wall-E is printed! Pinned him together (drilled holes in the mating surfaces, and stuffed 2mm aluminum rod into them as well as gluing) so hopefully he'll survive a little more toddler abuse.

Worked pretty well. I considered painting him, but my boy's not willing to wait - the model is sitting on top of my fridge with the glue drying, and he's sitting at the base of the fridge sobbing softly while changing "My Wall-E! My Wall-E!", so I'm just gonna hand him over as is once the glue is set.

So, The Boy dropped Wall-E today, and broke his neck and arm.

I assumed he'd break them off at the glue joints, but no: Apparently, the pinning+superglue is stronger than the plastic model itself. Good to know, I guess, but now I have to figure out how to repair a broken neck and arm :)

I'm thinking I'm going to superglue the parts together again, then build a reinforcing sleeve of sugru (that stuff is awesome) to protect the neck and arms going forward.

Turned off lights and heading to bed, when I realise my half of the living room has a couple LEDs. Just a couple.

Yeah, I keep a no led policy in the bedroom too... But it turns out having a router, three PC's, TV, KVM switches, mice, keyboards, three monitors, a 3D printer, raspberry pi Octoprint setup, and other silly little things in a small space adds up to a lot of random status LED's. Doesn't really matter, but thought it looked pretty cool in the dark. Shocks me how bright the red led is on the KVM switch - it's mounted on the underside of my desk, the big red circle is the light it's projecting on my floor!

Back into Fallout 4 for a bit; figured I may as well check out Nuka World, as I still haven't done that. Going for a cybernetically enhanced roboticist this time around; focusing entirely on intelligence and modding skills rather than the normal bout - just pistols for weapons, though I'll eventually grab heavy weapons as well. My first non-stealth playthrough!

The PLA and PETG are odorless and the whole getup is very clean. Makes it a lot easier to get Wife Approval :)

The printer CAN print abs, but needs upgrades to do it (primarily a different power supply, as the existing one can't really maintain the bed temperatures ABS needs. However, as PETG is basically equal across the board (except no acetone smoothing for post processing) there's little reason to use ABS at all imho.

First PETG print! 240 degree hot end, 60 degree bed, 25mm/s print speed, 30% infill. Printed nearly flawlessly, very smooth and strong. No zits, perfectly aligned layers (the new belt tensioners make all the difference there!), only very, very thin, minor stringing on the inside.

This stuff (PETG) is more temperature resistant than PLA, and stronger, so this is what I'll be building my D-Bot printer out of. The part here is a corner brace for the V-slot extrusion; I need 13 more of them >.<

Before I get into that, though, I'm going to build a mount for my E3D hot end - using US Water Rockets design, but adding on a brace plate for wiring connectors (so it's easy to change hot ends quickly in the future). The goal is to have a different sized nozzle on the other hot end, so I can just quickly disconnect one and connect another to get a different nozzle size, rather than having to screw around with actually changing nozzles.

Just got a PEI sheet from Amazon, and some 3M 467 adhesive film from Digikey because, as per usual, Amazon.ca doesn't sell what I actually want while Amazon.com does but won't ship to Canada. Anyhow, replaced the white masking tape on the build plate with the PEI sheet, releveled the bed, and am starting my first PEI based print.

While I always got good adhesion to the masking tape, I did find some issues with it rippling and not laying perfectly flat, which would leave visible marks on the bottom of my print. In addition, removing prints was difficult as often they'd stick too tightly to the tape, lifting the tape off the aluminum bed rather than peeling off it.

The PEI is pretty hard and glass-smooth, so here's hoping it works as well as it's proponents say.

Not different filament, it's a plastic sheet that I've glued to the aluminum build plate - the yellowish colored sheet. The extruded filament sticks to it nicely when being extruded, but pops off once it's cooled nicely. Getting both of these is tough - usually if a print is easy to remove, it's hard to get good adhesion while printing, or if you get good adhesion while printing it's hard to remove the print after.

Glass is popular, but somewhat of a pain to cut and often thick (or fragile), which leads to issues with having to adjust the Z axis (so the print head doesn't collide with the glass) or it breaking. Also, glass often needs a spray of adhesive (typically hair spray, spray glue, or just a rub a glue stick) to get the filament to stick on the first layer.

This Just Worked, wonderfully so.

My coworker gets to work this morning, says his tire made a scary clunk at the corner store down the street, then pulled hard to one side and made a lot of noise the rest of the way to work...

Oh, there's your problem.

Got Octoprint set up on an old first gen Raspberry Pi model B with a camera module. Works great; can take time lapse videos of prints! I just need to print one more track for Wall-E, then I can print a case for the Raspberry Pi + Camera and stand so it can be positioned for good video.

This also serves to untether my printer from my PC, so I don't need to worry about potentially borking a print job mid way though - something I never thought of until I realised, 5 hours into a print, that if anything caused my PC to crash I'd lose 5 hours of printing. And I've got a drawer full of old raspberry pi's anyways, so this is a good use for one.

I've already run into having a huge backlog of things to print. I've contemplated setting up a 3DHubs account to sell prints, but I don't have enough printer-hours to print my own stuff yet. Definitely need to build myself a bigger, faster printer!
OctoPrint is the snappy web interface for your 3D printer that allows you to control and monitor all aspects of your printer and print jobs, right from your browser.

It's an A&W. Pretty standard, but in 3 years they've never screwed up one of my orders, so that's unusual and great :)
