A Thingiverse Collection named: Printer - CoreXY / H-Bot. BLV mgn Cube - 3d printer. By Blv Jan 29, 2019. BLV mgn Cube - 3d printer. If you are willing to build your printer with sufficient rigidity the H-Bot design is probably. Son of MegaMax 3D printer: www.instructables.com.
Check out this 3D printer (translated) which [Arkadiusz Śpiewak] has been working on. When sending in the tip about his project he made the important distinction that it isn’t finished, but he has reached that critical threshold where he has printed items with it.
He decided to go with a design that is sometimes referred to as an H-bot. If you’re completely unfamiliar with it, you may find this H-bot design article helpful. The gist of it is that this technique makes it so that the motors used to move the extruder along the X and Y axes are themselves stationary. One large timing (toothed) belt makes a circuit around the top of this cube in the shape of the letter H. This is a bit easier to see in [Arkadiusz’s] rendered image found after the jump along with video of an early print test.
The Z axis uses two motors mounted along the bottom of the cube. These raise and lower the bead, instead of moving the extruder itself. All-in the printer should have a maximum object size of 30x30x30 centimeters. It’s being driven by a Smoothieboard, which was mentioned quite a bit when we were discussing using the RA driver board with a 3D printer.

Hi,
I'm quite new to making a 3D printer, I'm in a process of doing so. I've initially planned to move the motors with print head for X axis, but I saw these CoreXY printers and I decided to make the printer like that.
So I searched and saw a lot of different CoreXY implementations, if I can say it like that. So I saw the http://corexy.com/theory.html and understand how to place the belts and motors, but can someone please share a diagram like that for these other types of CoreXY like C-bot, D-bot etc.
I wan't to know what are the possibilities here, so I can chose the best one.
Thanks!
