Today we're going to install linear rails on the gantry of my wooden DIY 3D printer! Made from the cheapest aluminum angle stock I could find at my local hardware store, these guide surfaces somehow need to be attached to the gantry without inhibiting the natural expansion and shrinkage of the wood. To achieve this I decided to cut a dovetail dado for the aluminum rail to slide into, holding it firmly in place while simultaneously allowing for wood shrinkage as well as easy replacement should the rails wear out.

Keep in mind I got a few of these items during sale, so the total might well be above $50 now (especially with inflation)

Well, there we go! After everyone made sure the first video got enough views to render my desire to end the series useless; here's part 2 lol!
please dont drop this project because i wanna see how well wood 3d printer does :3
@@yusufmaulana960 has the advantage of less vibration than the cnc milling machine ..., it must minimize friction
@@yusufmaulana960 I used this system for my first cnc, it must have maximum precision in the realization of the channel ...
Nice progress!
finally here it comes :3 i hope this project never deprecated wkwkwk
Hi bro
Can you pls make a video on how to make a soldering iron
Already did, just look on my channel ;)
Did you patent the wheel? )))
Nah, I'm sure it'll be ripped off by everyone in a heartbeat, but that's OK 😂
Love the wooden frame! I made a CNC mill out of wood and it works great.
It will be exciting to see how well those rails work. I expect they'll be a bit noisy, but precise and long lasting.
Another cheap style of linear rail I've seen is drawer slides, from Ben Fleming's EDM book.
Also would be fun to try a simple 90 degree V groove in the frame with teflon sheet glued in it, and mating shape on the carriage to slide in it. Teflon-teflon friction is incredibly low. Even cheaper/easier to find and about just as good is HDPE sheet with graphite powder rubbed on it.
Thanks for the suggestions! After the pen plotter was done I wondered why I didn't just put a V groove in the frame which would have allowed simpler roller and carriage design much like on the Ender 3 - never considered a simple slide bearing though, especially not with teflon... Might be worth a try!
Please, don't stop! I am from Ukraine and I don't understand all what you say, but it is really interesting show )
Part 3 please
already used the system in my first cnc "Burrik7119" ... (you have complicated things ...)
... if the milling is not of the highest precision, it creates shrinkage, and bearing friction ... (the bearings must also be of good quality). it should be noted that the "w" bearings do not have an internal angle of 90 °, certainly less friction, but less stability ....
cant wait to see how this turns out. Looks pretty good stay with it your young with a sense of things and we need good engineers not more technicians. i hate fixing things but this is 2020 something if you want nice things you have to fix them and make them better. everything is designed to fail... find the fail point on common appliances and what not and replace them with better components. they are designed to fail it is job security. Technicians need paid too you know lol. me im just a caveman who lives in a van down by the river with a UA-cam Degree.
Awesome!!!!
I am from nepal
nice
I know you don't particulary like this project but it's a really good one. You are pretty much the only one I know that even tryed to make a 3D printer without one of those nema steppers. I don't know if there is anyone else have done one, but those motors are quite expensive, especially in places like latinamerica(where I'm from) and I think it would be a big step( ͡° ͜ʖ ͡°) in making those printers more accesible. Keep up the good work!!
I know, everyone just goes the easy route and buys the Nemas. There are a few (like 3 or something) 3D printers out there with steppers salvaged from old scanners, but nobody did a proper video about it. Keep in mind I'm also still doing it the easiest way possible by using those microstepping drivers, which, imho should be replaced with something cheaper as well. Unfortunately I'm not good enough at programming to do it entirely without motor drivers, as that would require pretty much altering the software from ground up - on top of adapting mechanical design of the machine to fit the unique stepper motors.
But with any luck I'll come up with some radical changes to make DIY CNC in general more accessible within the next couple of years. I have some interesting concepts that are yet to be explored :)
@@ChronicMechatronic My dude, you are not even using a shield ramps, that's already like a whole different level of DIY that none of the DIY 3d printers ever made(that've seen at least) also, the drivers aren't that expensive either, you can take the licence. Assembler is not that fun as it looks like
PD: Have you ever tryed making anything with the delta structure? those things are hypnotic
@@Eduardo-so9mk no I didn't dare even think about the delta design yet, as I presume there would be a lot of trigonometry involved with the firmware. Also the need of 3 identical stepper motors would further complicate things since it's hard to find similar steppers in e-waste...
@@ChronicMechatronic The word you are looking for is not "complicated", is "Fun"(????
U r video's are so interested

content hoarding is making your channel slump good project though
