Great job Rolohaun! You have done so well designing these printers. I am excited to see what's to come. Pat yourself on the back for giving the open-source community many options.
This is a great video and does exactly what you hoped. Can't wait to see the full size panda and Delta plans, but I'm definitely getting a rook once I finish my V0.
Defiant seems to be the next one I want to build. I've been looking into the k3 for a while now it just seems so cool and probably one of the faster of the bunch

I like the idea of the Fortress - it combines the linear rail XY mechanics which seem evolved from simple core with a single motor Y. The core advantage of the latter is that it fits boards which don't have 5 independent motor controls. One other positive is that the printer seems to be easily adaptable to other frame & bed sizes.
Fantastic summary, thank you. Love your honesty. I'm stuck on my (non-MK1) Rook 2020 build currently - so I'm both happy and sad that a MK1 version is coming out. That's the fun of open projects and I wouldn't have it any other way! I'm very keen to see a small delta for desktop use. They are so impressive to show off to people. Can it use 2020 and/or 2040 extrusion too? Now that I've got an aluminimum blade for my drop saw I want to use 2020 for everything! :-D Thanks again for keeping DIY printers alive.
yes a small delta is going to be awesome! Hopefully your on the discord and get that 2020 built. You can always upgrade your 2020 to MK1 later there are only a few extra parts to do so and some printing which is the best part haha
Hey there! Nice work! I'm deciding on my next project. I'm looking for a large volume corexy design and I don't need motion system speed as i expect to be bottlenecked at my hotend flow rate through large nozzles. The simplecore legacy looks perfect as the simplest and cheapest thing that could work while still retaining great quality. You mentioned that you expect the Panda line to replace simplecore, however I'm curious as the Panda seems to emphasize speed at extra cost and complexity. In addition, the Panda mini doesn't support the same volume that is available with SimpleCore. Is Panda a good idea and will it scale up, or should i stick with simple core?
I am currently building a rook 180, in 235 extended version. Your bom for it should add 4 35mm screws and reduce 4 30mm screws for the links seeing as the top rear links are too thick for the 30mm listed in the bom
Is there a kit that comes with the printed parts or another source for good quality parts ? I have the slight problem that I don't have a 3D printer yet so I can't print the parts myself
I don't like the Fortress with a single motor for the Z axis. The whole idea with a "3 point" is to have separate control of each point. The Defiant is much better. I asked this before in another video. Do you have a printer that uses carbon fiber rods? Oh, and I love your other printers. Going to build one, just have not decided yet. 👍
Carbon rods will a good OD tolerance hard hard to find for DIY, I probably won't ever use them. 3 points supporting the bed is always a good option weather it has 1 stepper or 3. Controlling each point has a con that it's only as good as your probe and sometimes that can not be acurate enough.
@@Rolohaun Good point on the leveling. Didn't think that way, because of probe leveling. I guess it works if you use springs and screws to level. I seen a RU-vid video a week ago of a guy using carbon fiber rods from AlliExpress. I thought that was how I found you. Looks very good. I have even considered buying the y-Axis from Bambo Labs and using the whole thing on different builds. Actually "Keep a secret"? I am doing that exact thing. But the videoes will not be uploaded untill Winter. So don't steal my idea. :)
I have a request for you since you are so good with designing printers, why not convert a ender 3 pro to a core XY as a project? I know there are many people out there who have already built it but there is still a lot of scope to make it better. You know it is one of the most common printers out there and when it comes to reliability in printing it sucks. So if you have the time can you please consider my request and do your magic. A lot of people out there struggling with their enders will benefit
There's the Ender 3 NG project by RH3D here on youtube which seems pretty developed. In my opinion the Ender 3 isn't very suitable for a CoreXY conversion. The frame is lacking in both size and number of extrusions, having large parts of the frame 3d printed negates the stiffness of the original aluminium extrusions. The motion system (v-wheels) is probably not going to be used if you want high speeds, so you need to buy either linear rods or rails (=expensive). For the Z axis the most cost affective solution would probably be to reuse the v-wheels, the NG uses 3 lead screws and 2 linear rods which you mostly have to just buy. So in the end you're constricted for the frame if you want to reuse the old frame and most of the other parts you end up buying. A decent aluminium CoreXY cube frame isn't that expensive to make (I made one for 50-60 euros) ...
@@Rolohaun It is also why I am finding your videos here and getting a lot of interesting takes on the designs. I still have a very old prusa with many changes over time and now I am thinking to have a nice project to convert it to corexy, but of course try to reuse a lot of things to keep cost down. I dont have an actual need for another printer, but yeah would like to have one that's as fast with decent quality as I can get it and some fun building it:).
dude, your work is AMAZING, never quit. Would you be open to consider making a machine using zipties as hardware? me and a couple of friends are trying to boil the cost of making a 3Dprinter down to next to nothing Traditional Japanese Jointry is our secret weapon ;)
