Experimental Crossed Cantilever 3D Printer: Last Two Benchies

[@peterfoldesi483]

A single aluminum square tube behind each linear rails could help a lot with rigidity, and it would cost next to nothing as well With that and a bowden setup I believe it could reach ridiculous acceleration and speed

[@Eric_In_SF]

Took me a second to see what was going on, but that’s actually pretty clever. Now it’s got me thinking about a system, similar with just having another set of rails on the other side with the belts extended all the way around.

[@elboniske]

You just invented ultimaker

[@illRun4Clownident]

Just a thought: Look into preloaded bearings

[@Gabs_Labs]

Very cool idea!

[@willcubemakes]

Love to see more progress! Are you eventually going to trade that wood plate in favor of a 3d printed/cnc'd plate?

[@CasualCNC]

In this form it was flexing a lot, in the next iteration I'll try one fully 3d-printed.

[@willcubemakes]

@@CasualCNC As a bonus, it will be easier to make more without sacrificing consistency!

[@dhivan]

This is so amazing

[@Brocknoviatch]

Coming along nicely!

[@oscargatenby-thomas5653]

Could you make a dual nozle setup by having one "dock" by going into its corner and another coming from opposite side i wonder if thats possible

[@gsestream]

double up the supports, from all sides, but you dont have to motorize the other side

[@Iisakki3000]

Interesting setup

[@Michael-j2r2d]

Well it works quite reasonably. I'm not sure why you've chosen a dual cantilever design. Is it space saving or access? Ether way great stuff Personally i think, an Hbot style cantilever might work better. XY motors to the rear and Z rails 2/3rds to 3/4th to back (or where ever the average balance point would be). Does close off one side a little more but should keep access about the same. It would remove one brace and add four idler pulleys so no real weight changes.

[@CasualCNC]

The design had no specific purpose, just trying out something different. It might seem like a space saver on the first look, but print-part / printer-size ratio is not that good. However, placed on a desk, it feels so much smaller than an enclosed one. "Looking cool" is probably the biggest advantage of this printer. There is some magic when it prints.

[@SultanAlAmeer]

This is really interesting can you share the STL files of your work progress?🙏 Im interested to build one i have all the parts needed for this design.

[@SultanAlAmeer]

It is one of the best design good job 👍

[@bluemat.]

Very cool project, are this 3D printer running on klipper software? and is running on a default cartesian kinematics?

[@CasualCNC]

It is default cartesian running on Marlin in this video. Next iteration will use klipper, HW is underway.

[@bluemat.]

I get it, yours printer reminds me core xy kinematics. On klipper you can expand printer capabilities for sensorless homing, input shaping and other nice features.

[@brockm2263]

I love this project, is it gonna be open scource, if so then when is it gonna release.

[@CasualCNC]

I haven't decided on that yet.

[@badgermcbadger1968]

Why would you want to make one anyways, it's a gimmick design

[@seelyw.4818]

Super spannend - weiter so!

[@CasualCNC]

Danke! Die zweite Iteration ist unterwegs und ich hoffe auf spürbare Verbesserung.

[@Eliasporchet]

Build series?

[@LeShrimpDuMer]

Is it a cnc shield? And are there any alternatives?

[@CasualCNC]

The version in video uses Arduino MEGA with RAMPS v1.6 running marlin firmware New iteration I'm currently working on is based on Manta M5P running klipper, which I definitely find to be a better alternative, but more expensive.

[@3707_here]

It’s a CoreXY sliced inhalf…

[@m_IDEX]

Nice! 👍

[@JermyCoon]

Impresionante

[@maks-i3b]

Coll design, what hotend are you using?

[@CasualCNC]

At the moment it is a really cheap one: DollaTek Metal J-Kopf V6

[@maks-i3b]

@@CasualCNC Ok, so it's a v3d V6 clone. How do you think how will ender 3 style hotend perform there?

[@CasualCNC]

@@maks-i3b On the first iteration, I wasn't paying much attention to the hotend. I've replaced the original 35 W heater cartridge by 50 W one due to a broken cable. Heavy blobs seen on the second benchy may very likely be improved by tuning the extrusion. This printer won't reach extremely high printing speeds, so a high performance hotend won't bring much, I assume. Any advice on which hotend should I go with?

[@elementzero_0]

i love this and need more. Please turn your channel into you thinking of and testing novel 3d printer ideas. Heres an idea, a 3d printer that has 4 legs and a nozzle in the middle of the body where a belly button might be. Then you can have it print, maybe even crawls around and print. Heres another idea, a large scara 3d printer, like where the arm is 1 meter plus long. im a hardware guy, so i can design the items but cant code the software, so i have all these ideas but cant make them work.

[@mattgavioli6762]

it's an interesting concept, but it's one i don't find an actual point about... i mean, it's undeniably novel and cool looking, but compared to a cantilever i3 cartesian printer you're not reducing the footprint of the machine that much, and it loses for sure a lot of the rigidity that's exprected from a "cube" chassis printer i'd be glad if you could provide other infos about the machine aside from that, good job!

[@kennykd97]

its stupid just use normal cartesian and save 2 linear rails
