Are Cantilever 3D PRINTERS still VIABLE!? (KP3S, Prusa Mini, etc.)

👉🏻 Are CANTILEVER 3D PRINTERS still viable in 2023 AND BEYOND? Well, this is the question I will be answering in this video and providing a detailed comparison of the prints. And what better way to do that than modifying the KP3S PRO cantilever 3d printer with dual z linear rails.

I have only owned one cantilever printer, a RatRig VMinion. It is my favorite printer for low layer height small form factor detailed prints. Naturally being a RatRig it's been run with Klipper from the day I finished building it. Funny thing it that it does it's best at up to 70 mm/sec or 100 to 130 mm/sec, VFA shows up right around 90, must be hitting some resonance. Interesting video. Stay well!

Well done with this video. All the causes were examined and fully explained with good fixes. You earned a new subscriber!

I just recently built a homebrew cantilever for fun using ender 3 parts and a Bambu a1 mini bed. Fully tuned it with klipper. I get the waves like you showed but I plan on using it for quick prototypes of small parts so it’s fine for me. I like the small size of it and it was fun to make

[GillesBruno]

Same here ! I was just taking the klipper route ... and finally changed my mind : thanks !

[tadeus]

Great video! I dont use bearing on single Z, is it necessary on dual?

[mg_customs]

I love that channel! Whats the cube you're printing off? Looks like a good benchmark test

I still have and use my original Ender 2 cantilever printer and despite having many printers and even one that cost 18 times the cost of the Ender 2 this Ender 2 is my most reliable printer, I can just send it a file and dont even bother to watch the first layer go down, it just works, I have thought of adding linear rails to it but considering I have it set up absolutely perfect I dont want to risk spoiling it, it will get some new POM wheels eventualy and I have already swapped all the fans for quieter ones and added a part cooling fan (yes they came without part cooling as PLA had only just become popular) and have a spring steel magnetic textured PEI bed on it. whenever I have a part that will fit on this machine I use it despite having a printer that will print 4 times faster, I just love using the Ender 2!

Does this mod work for a regular kp3s V1?

[stefanguiton]

The quality of these videos are great!

I think about modifying a Prusa mini. The problem there in my opinion is the belt tensioner of the x-axis, as the x-axis is made of two rods with a plastic part for the idler at the end. You adjust belt tension by turning two normal screws. This means the lenght of x-axis variates a bit when adjusting the belt tension. So in adition to the extra z also modification of x is needed.
But still it might be an interesting project.

Dropping in my two cents a year later.
What is there against printing outer walls first and only lowering acceleration for those? I already did that on an older printer.

[DuyNguyen-muml]

I really like your design. i thought about it but don't know how to make the z axis the best. Thank you very much. I printing the parts and will assemble it shortly.

Try linear advance and input shaping or just go for klipper, i do that😊

[TechieSewing]

I like the idea of cantilevers as good enough solutions: small, light, cheap. Still Klipper is good even with slower speeds, especially compared to native firmware with no 'preheat PLA' command?
I do like how it looks with two rails, there is that completeness of square frames.

[ivanhernandezsanchez]

Can i try it on my kp3s? (NO KP3S PRO)

[cristianjosadec]

Hello, very good inf i have the kp3s since they came out, now with the Bambulab A1 the game change about the speed but for the price i would prefer a bigger machine .

Like the Ender 3 v3 se that is very cheap and can print at 250mm or Neptune 4 even faster .

[stevehofner]

Well I think about putting my KP3s into an Ender 3 frame and allready converted the frame to the belted z-axis mod. Still not sure if it it really worth all the effords and required time to develop and print adapters...

[FilmFactry]

Two things: What if the bed (y axis) was isolated (independent) from the print head (X and Z motion). No transfer of vibration. What if you used a dual rail on a single Z column.

[Michael_john_mentzer]

im def making this whe n iget my kingroon kp3s pro v2, its so cute

[Pony_Tech]

does it jam without the second screw on the Z axis?
