A tutorial of building a High-Speed 3D CoreXY Printer from complete scratch. Can I beat the Bambulabs with a frugal 3D Printer made from available spare parts on hand? Let's find out! :D
PDF guides, BOM, Links & Firmware Samples GDrive link: drive.google.com/drive/folder...
A FRANKENSTEIN BUILD:
Like many others involved in 3D printing, one often accumulates spare parts and discarded components from past 3D printer upgrades and modifications. If you have some spares lying around, you can indeed put them to good use by building a fast CoreXY printer out of them.
TESTING THE FORBIDDEN IDEA:
Is it feasible to weld a steel frame for a 3D printer? (A question that has intrigued the 3D printing community for quite some time.) It's an idea that is often dismissed, as the possibility of building a skewed and misaligned frame is highly likely. The video shows how to overcome that obstacle and defy the old 3D printing taboo of using a welded steel frame.
WHY WELDED STEEL?:
3D printers are often built with aluminum profiles costing around +$100 for CoreXY designs. However, if built around a frame made from home-welded steel tubulars, the frame cost would go down to $4. Steel tubulars are common and abundant, as they are used as home construction materials. The idea of using a welded frame also introduces possible benefits for increased rigidity, essential for high-speed CoreXY builds.
MY JOURNEY IN 3D PRINTING:
Building the courage to construct a CoreXY printer was something I had to overcome. I started my 3D printing hobby back in 2015, with the ANET A6 (pre-release) being my first 3D printer. At that time, affordable printers came in kits you had to assemble with a provided box of materials. This experience played a crucial role in giving me an understanding of how 3D printers work. In 2016, I got my first SLA printer (FSL Pegasus) and my second FDM printer (CR10). From 2016 to 2023, my CR10 remained my main workhorse and favorite. I never really had a reason to upgrade to a new printer, as I was happy with my unit. I just needed something that works, and my urge to stay up-to-date in 3D Printing died down. In 2023, upon seeing the release of Bambulabs (the new kid in town), I finally had the urge to buy a new printer. This is when I discovered the world of Vorons and CoreXY communities existed. I had so much 3D printer junk by this time, so I decided to build my 3D printer from scratch in 2023, the MK1. It was a cantilever bed slinger design; I filmed a tutorial for it, but I never released it as I considered it to be a failure, as it was only as fast as any Ender 3 or i3. By the end of 2023, I finally decided to build my MK2 based on a speedy CoreXY design inspired by seeing Vorons. It was a personal project I never got to document into a video. After a few months of use, I was really happy with it! Thus, I made the MK3 specifically to be filmed for this video tutorial.
UPCOMING PREQUEL:
The entire video's original runtime was around 59 minutes long. I had to cut them down into chunks. I made a "How to design a CoreXY" chapter, which was removed from the initial release and will be uploaded separately.

I'm Back! :D Some of the cruddy components used were intentional. I just wanted to bring life to some of my old discarded 3D printing components. Holding a square with shorts, the machine is not designed to be a precision build, it was literally just a frugal project for the thrill of doing so. I'll update you all when I migrate to Klipper. Hopefully input shaping would make an impact on the next test prints.

Some notes about welding from a professional MIG welder; Get comfortable. Don't be anxious or anything; welding requires a steady hand. Especially on thin steel like you're doing here. Sit down to weld until you get comfortable enough to stand and weld. Get your face closer to the weld, so you can really see what's happening. Don't be scared of it. Yes, weld spatter will get on you. Yes, it burns. You get used to it. I usually weld with my face as close to the weld as I can, less than a foot (30 cm) away at most. You need to be able to see the weld puddle flowing to where you want it to go. The puddle will do what it wants and you must simply guide it in the direction you want it to go. You need gloves. That will let you get closer to your project and brace yourself for smoother lines. Imagine trying to draw a perfectly smooth, straight line with a pencil on paper without touching the desk, while holding the pencil by the eraser with one hand. This is effectively how you're welding here. Use your off hand as a brace for your torch hand to pivot on, don't grab the torch with both hands. I usually rest my elbow or forearm on the bench. Also, what you're using as a thumb rest is just a hook to hang the torch by. Torch height and angle is very important. This is what appears to have caused the excessive spatter and the majority of holes in your welds. Proper height and angle allows for correct heat distribution and wire feed for good penetration, assuming you're using flux-core wire. If you're not, then you need gas and height and angle are even more important so the weld puddle stays shielded by the gas. You want to stay between 5-15 degrees from perpendicular, and the wire should stick out around 3/8" (1 cm) from the nozzle. If you're using flux-core, you should "drag" the torch away from the weld, and double the stick out to 3/4" (2 cm). Also, flux-core wire produces slag that needs to be chipped away with a chipping hammer. Very basic settings guide: If it's just popping and not making a consistent puddle, turn your wire feed speed up. If you're getting excess spatter with correct torch height and angle, turn your feed speed down. If you're making a weld that looks like a worm sitting on the surface of the metal, turn your heat up. If you're burning through too quickly, turn your heat down. Of course, settings are very important. But you also have to match your travel speed to your settings. Too fast and you won't get good enough penetration. Too slow and you'll burn a hole right through. You want it to have a consistent "sizzling" sound, and the edges of the weld should be flush with the surrounding material. Also, make sure to match your wire to the type of welding you're doing. Pay attention to the diameter. You'll need different torch tips for different wire diameters. Tips and cups are consumables, and will need to be replaced often. Gloves and hood glass, too. I go through a glass a day, a pair of gloves a week, and tips every few days. Of course, I'm welding 10 hours a day. Finally, welding is a skill. It takes practice. It took me at least 100 hours to feel even somewhat comfortable doing what I'm doing. Practice on anything you can find to weld together. Start with welding on flat, then progress to vertical. Get comfortable; you should feel like you're sitting at a desk and doodling. Grind your metal before welding it. Weld straight lines on a scrap piece of metal. Practice different weld joints, starting with butt welds, then progress to laps and corners. You're doing great, for a beginner. My welds looked worse.

This reminds me so much of the starting days of 3d printing, when there were no kits or tools specific for 3d printers, so you had to go around the hardware shop to find what you needed and use old pc power supplies as power source.... And in the end if you printed a cube that looked more or less like a cube it was such a success

@TechBuilder 2 ай бұрын

Those were the days! 😭I can recall when I was little and asked my parents for a RepRap, I had a hard time convincing (in 2010) on how useful it can be at home. I waited a few years later until I can afford a printer with my savings, eventually I got the Anet A6 (i3 clone). I really missed the days when a bunch of parts I never knew existed (that all came in a box) and had to install them like Legos. The first print was the most rewarding thing I've ever felt at that time. The excitement would probably have been much more intense back during the pre RepRap's Mendel era, those things were so bare and crude getting to print a cube would have been indeed immensely rewarding.

@quigleyscorner4881 2 ай бұрын

This is a great inspiration because I have tons of old parts lying around. I started with the Mendel v2, un 2011. The only place to get printed parts was through eBay, and hardware vitamins and minerals from Home Depot. there were no commercial printers designed for desktop. We printed our own extruders from PLA or ABS - and they worked better than the MK series without gear reduction. There were no 1.75 versions, and now I'm left with dozens of spools of 3mm (not 2.85, actually 3mm) spools. I am designing a retrofit extruder.

Welding; Some tips here from a automotive fabbricobbler: Get shielding gas and throw that core flux garbage in the bin. Tap weld first each corner, i'd fabricate this by building the top and bottom squares first, just a spot weld on each corner, cross measure, machinist square to check it's square too, and you should be able to get within 0.1mm relatively easily with just tape measure -- errors show exponentially when cross referencing. Add more spot welds, allow that corner to cool while spot welding the opposite, and go cross hatch opposites, regularly rechecking it remains square. REMEMBER; Smaller the issue, bigger the hammer! So if you are off by say 0.25mm you'll need a big hammer. Fortunately, small single handled steel mallets are only like 5$ Remember to well all 4 sides fully for maximal strength. Cooling allow the stresses to give up, and as you add spot welds, it gets harder and harder to get off square, but more internal stresses will build if you go too fast. After the 2 squares are done, then just the uprights, same process but this time after first or second spot welds on each corner i would probably add on top a 25kg or 2 sacks as weight to force it to be in place and allow me to weld it faster together. Otherwise the same procedure. Slow is smooth, smooth is fast; So without weights and time you can get it better squared. **NOW ALTERNATIVE METHOD** Print huge stiff corner brackets on 45 degree angle. Adjustable, no welding, no heat shrinkage / thermal expansion / thermal warp issues. See how Slant3D has made their Mason printers. Tho much less stiff, you need 10x thickness for PLA to be as stiff as steel. So for 1.5mm wall steel RHS, you need 15mm walls, or a minimum of 15mm fully solid plastic to match the stiffness.

I know you said this was your first foray into mig welding, just a word of caution for you, besides your inexperience with welding, the fact that the steel was galvanised would be another reason you had issues, but the big concern is that you tried to weld through the zinc instead of grinding it away before you weld. This is a big no-no in fabrication and should be avoided at all costs. You are young and most likely not had any issues because of it, but please, going forward, remove the shiney coating before welding .or better still, just don't do it.

@chrismichaelyoung 2 ай бұрын

Inhaling zinc fumes will cause cancer. Welding without proper clothing will cause melanoma (also cancer). And yeah, galvanized metal is overkill if he's just gonna paint it anyway.

You can actually tell by the uniformity of the surface that this is definitely not galvanized. Galvanized almost always has variations and or a pattern, along with a silvery color that looks like silver spray paint. This is most definitely plain uncoated cheap mild steel. But this is the internet, and there are always know it alls that have to add their incorrect inputs. So keep doing your thing!

Small tips : you could add a fan blowing on the SKR E3 for better cooling of the drivers. You could also do go direct drive by printing a Sherpa Mini/Micro extruder housing, and just get cheap BMG internals and a cheap Nema 14 8/10 teeths motor. You could also print frame braces to stiffen the frame more, as you plan on printing fast with it. Good job again !

Thank you! That sherpa BMG tip sounds good! I'll consider it! :D While I haven't had problems with my SKR Minis running without fans, my peace of mind does suffer thinking one day it could break without cooling. Thanks for bringing this out, you've encouraged me enough to add fans on it. Cheers!

I initially thought KZfaq is pushing another clic bait.. But you have done a great job with this one.. Impressive.

I landed here as i am using an old Ender 3 Frame right now for Rebuilding it to an Voron Switchwire configuration. Your build is realy great, without Heatchamber i would compare it more to an very upgraded Tronxy Setup, i got my X5SA-400 pro up to 300mm/s with standard Parts, and some additional Printed Parts inclusiv an Dragonfly Hotend. For others which can't weld, maybe look into a Printer called Teebot. I got the Suitecase Version from 2014. You need a Printer but there the Corners were printed connectors for Steel Tubulars Screwed together. Very Solid. The biggest Advantage in my Opinion of Steel Tubulars are Magnet Add ons and Mass. The Heavier a 3D Printer is the higher his Innertia, which in it self reduces vibrations. A Steel Tubular Printer makes so much sense thinking about it, that the only reason not using it maybe the Problems in properly Welding it. You seem to have found a great solution: Good enough to Adjust the Rails for it. Very ingenius Solution which lot of Builders don't think of it as they are fixated on Aluminium. There a 0.3° deviation will be carried over to the Rails, thats why they don't weld it. On a Flat Steel surface you can correct it. I think thats why your Mark III is better then your Mark II in deviation.

Well done! the quality is shocking, but the fact that you still designed it and it works is an achievement lol You got skills and luckily for you, you can get the parts cheap enough to make a monster. Well done once again!

I once heard that if you have woodworking skills, every problem looks like a woodworking project, if you can weld, EVERYTHING becomes a welding project! When I bought my first welder, I found this to be true. Welding is FAR cheaper than the alternatives, primarily because steel is cheap. It doesn't even matter if you can't create perfect (or even good) "lapped coin" welds, ...you just need to grind A LOT (and you will use a lot more spools of wire.)

Genuinely loved this video. I'll be replicating it soon as it's cheaper to use the material you've used than ordering the pre cut aluminum frame

Watched this whole thing knowing I’d never take the time to make my own printer. Really good video and put together very well. I’m sure all of the editing and footage took a lot of time!

Thank you! The editing took more than 2 weeks to finish apparently. It made me feel burnt out as of the moment, I'll probably take a few weeks of rest before I start the next video haha

Way to go! Great project. I can't weld either and it is a skill that I would like to learn. I might suggest that although squareness is very important rigidity is even more important and with a steel frame you get a lot more rigidity and stability so it will be interesting to hear if this translates into better prints as compared to bolted together aluminum extrusion frames... I am not sure about some of the 3D prints for things like motor mounts. If it is something like a plate that is simply being evenly compressed (such as an adapter plate for a motor to the linear motion hardware) but if there are any cantilevered features, etc then there will be some flex going back into your project. Your Benchy and vase at slower print speeds looked good by the way! Overall great project - i am impressed.
