Sold the Ender 3 clone, cleaned up the modified ender 5 pro and listed it locally now as well.

In the mean time been increasing the work the K1C has been doing. The Ender 3 clone I had rigged up with a pi 3b for octoprint and new owner didn't want it. So it needed a new home as ill repurpose it as a DreamPi, just waiting on the modem to show up.

Printed a little hot which made the hexagons not come out quite right but the more I used a 0.6mm nozzle for grunt work the happier I have been with the print times.

Designed and printed a new handle for the sliding screen door.

Replaced a part on the CNC to realize there was another broken part. Going to try modifying it a little to make it beefier to prevent a repeat. Thankfully happened while not in use.

And ever since I saw glow in the dark filament I had the urge to construct additional pylons. 5V UV led came in so they will glow nicely. This model doesn't scale up to the size of a paper towel roll nicely and needs to be tweaked if I make more than 2 but good starting point.

has anyone played with those combo CnC machines? the ones that run from $2K - $5K or so?

I looked at them very very closely and I almost bit, the snap maker one is even on sale right now through RepRap warehouse (I assume this is the kind you mean anyways)

Snapmaker Modular 3-in-1 A350T (Flash Sale)

A350T has several upgrades based on Snapmaker A350, offering a faster and quieter printing experience. The product includes everything you need to start your maker journey: Newly designed Linear Modules Newly designed 3D Printing Module Newly designed Power Module with intelligent fan speed...

Honestly I had almost bit on buying one but working area is why I didn't. For me a CNC is most useful in large format, processing a full sheet of plywood is functionally extremely useful for me. CNC small things less so that can be made with cheaper/smaller tools. That and the cool things like the rotary attachment (to make say chess pieces out of wood) are extra.

The lowrider CNC basically cost about the same once assembled but now I can cust 4x8ft material vs 350x350mm. Also I was eyeballing it before my hatred of bed slinger designs.

I need a new surface to host the printers and wash station. So I picked up one of these cheap workbenches.

The ikea desk I have been using is just not solid enough. But while I have been assembling this thing it hit me that if you bought two of them and mixed and matched that parts. If you assemble two "backs" together so you had 4 tall posts instead of a front and back and using a couple sheets of plywood /plexi would make a really good start for an enclosed space. And you would still get enough pieces for 2 work benches. One of them would simply be a single height without the tall part.

Very similar workbenches are availiable from a lot of stores most of them not priced very high.

I'm not quite set on doing it myself since I have a secondary chamber for the resin printer but it might be worthwhile for someone else.

I know a lot of people using shelving racks and something similar can easily be done but the addition of a couple drawers for nozzles and such is a nice addition.

I had to take the top shelf off because the 3d printer tent is a little too tall. But all the spare nozzles, cleaning tools, wrenches, allen keys etc are all in the drawers now. Filaments are in the sealed tote with desiccant. What doesn't work about this right now is the wash station. The resin printer the lid in on a hinge, the wash station it needs to come up so I'd have to pull it out each time I use it. I think I have something better it can sit on then I can use an additional tote for the resins and related and shove that where the wash station is now.

Last little while all of this has been sitting on the CNC so it hasn't been getting used. All of this having it's own organized home should really help.

Also i had the resin printer in a home made ikea enclosure but the door broke on me and this branded one was BNIB on market place for cheap. If it wasn't for the additional enclosure there would be enough clearance for the top shelf, or to build a in place enclosure as mentioned above.

Shorter half got me a second workbench. Wash station now accessible and have some open space to do things like soldering since the garage is still unheated I can keep doing things more comfortably though the winter.

Also made just enough selling a fancier server to pay for a ferret pro 3d scanner including the taxes, was hard to justify buying one otherwise.

Prusa finally came out with a Core XY printer.

Prusa CORE One+ | Original Prusa 3D printers directly from Josef Prusa

The CORE One+ is a fully enclosed CoreXY 3D printer with active temperature control designed for top print quality and speed. Easy to set up and made to last, this rugged machine is perfect for beginners and professionals alike. Designed and manufactured in the EU. Get the most out of your CORE...

I think they are too late and too expensive. The Creality K1Max is under $1000 CDN, while the Core One kit is $949 US plus shipping and duty. The K1Max is 300x300x300 build volume vs. 220x250x270 for the Prusa. Maybe they think their only competition is the Bambu X1C?

I forgot to post what I've been working on lately. My dad used to build fly-by-wire gas powered model planes when I was a kid. I've always been interested in remote controlled planes since that day, so I decided that my next project would be to 3D print my own RC plane.

Note: Any RC plane, drone or helicopter over 250 grams requires you to get an RPAS license in Canada. I don't have one yet, but plan to get one before I ever attempt flying this thing. Info here: https://tc.canada.ca/en/aviation/drone-safety

I decided on building a trainer. This is the Eclipson Go 1 Wolf, modeled after a pre-WWII glider. The model is free. Eclipson's models are very well reviewed by Flite Test on YouTube. https://www.eclipson-airplanes.com/

I bought a roll of eSun foaming PLA-LW. After a few attempts, I finally dialed in the settings in Cura and ended up with this after about 70 hours of printing (print speed is limited to ~50 mm/s with foaming PLA)



What you see used up less than 1/3 of a roll. The exterior skins are only 1 layer thick at .4 mm so it's super light. So far I've had time to glue up the fuselage then had to put the parts away for a couple weeks while we had an aborted attempt at selling our house. I intend to assemble the wing, ailerons and elevator flaps then paint it all white with some leftover rattle-can lacquer I have (the filament is more beige than white). I'll put some red striping on the wings and rudder so it's more visible from farther away although not the patterns Eclipson shows.

The random parts I'm buying to make it will add up to around $200. They will be reused when I crash this. It's inevitable. The idea is that you can just re-print the parts you break and re-build for cheap. Eclipson uses the same servos and motor for all their models with the idea that you can re-use them on another model when you are tired of flying this one. For me this is a proof-of-concept, to make sure I can build something that will fly and land. Then I hope to make other models that are capable of more aerobatic flight once I have a few flights under my belt. I also bought a small P51D warbird off Amazon to hopefully get used to RC flying in real life but the weather's been crappy. I've spent many hours in flight sims over the years, dating back to Falcon 3.0.

Anybody else on here ever done something similar? I'd love to hear about your experience.

Local retailer taking pre-orders on k2+ (350x350) for $1800... I don't know if at the price it included the multi-material or not.

I'md still really happy with the K1C. if I was to complain about anything about it so far is that the X1c multimaterial would have been nice but wasn't happening for the price difference (k1c + 10W laser was cheaper than the P1P?) but really I have hit a few times where the K1C is just a little small and kinda wish I had a hardened K1-Max instead (doing a lot of CF, wood, did an aluminum mini sword last week really like that one).
