WHAT TO LOOK FOR IN A COREXY DESIGN

SolidCore CoreXY Belt Path Diagram
SolidCore CoreXY Belt Path Diagram

When you think about a good machine build you have to consider a few things. How developed is the design? Many common designs will have:

  • Contributors designing fixes, mods and other spun off remixes.
  • How many mods are there that could allow you to modify your printer for custom applications
  • Is there a user group that you use as a resource to troubleshoot or upgrade and update your build. While there are many resources to draw upon User groups will keep you in the circle of news, updates and creative solutions.

SolidCore CoreXY Mechanical Arrangement

The mechanical arrangement of components such as motor and idler mounts, linear rails, carriage and gantry may or may not allow for add-ons such as an enclosure or heated chamber. For example, motor and idler mounts placed on the inside corners of the frame gives the needed clearance to mount an enclosure. Each design has it’s own advantages and disadvantages. The configuration above eliminates any design constraints of scalability so the overall length and width of the 3d printer build can be completely scalable.

HeVort DIY 3D Printer: Non-Planer 3D Printing

The HeVort is a design that takes bed leveling to the next level. The Hevort 3-point bed tilt also changes the way parts need to be supported so for models with overhangs facing ‘uphill’ into the angle, supports aren’t needed. Although non-planar printing is not really widely implemented yet, there are new slicer post and processor components  for printing at fixed angles other than 90.  In the future, we may see more non-planar printing. This would allow you to print a part in vertical mode and add another component at an angle without need of support material or other mechanical aids.

With non-planar printing becoming more and more popular, it’s not surprising that slicer toolpaths are available. This means you can optimize how your layers are printed and reduce support needed thanks to angled orientation. One problem with 3D printing is that it can be difficult to support overhangs.

The HeVort uses a mechanical setup that consists of linear rails mounted to the bottom of the build plate along with 3-point bed leveling. It’s a concept called Non-planer 3d printing. Some refer to the setup as True Bed Leveling.

As slicer software advances, software will soon be able to generate optimized toolpaths for printing fixed angles. Combined with layer optimization, support material will no longer be needed.

CrazyCreatorCube Toolchanger

The CrazyCreatorCube Toolchanger was designed by Hendrik and Andy to develop a stable and efficient tool changer 3d printer. The main focus of this tool-changer project is to make a 3d printer tool changer with great 3d printing quality, easy maintenance, and cost efficiency.

E3D Tool Plate Compatible

The tool changinging 3d printer is 100% compatible with E3D tools and 99% of the CrazyCreatorCube parts can be found in stores or ordered online. Another goal of the 3d printer project is that the printer build should be possible for anyone with basic technical knowledge to build and assemble the CrazyCreatorCube.

Kinematic Bed System

The 350mm x 330mm bed or build plate uses a kinematic system to connect to the bed supports and the heated bed is moved along three axes and completely auto leveled.

Magnetic Tool-Changer

The magnetic ToolChanger uses a remote system which means the motor that rotates the safety bolt and holds the tool on the tool changer, sits on the frame and does not increase the weight of the print head.

Print-Head / Extruder

While a remote extruder is used in the classic CrazyCreatorCube version, a normal Direct drive extruder or Bowden extruder can also be used.\

Voron 3D Printer

BEST COREXY 3D PRINTERS 2021

VORON 2.4

The Voron V2 by Voron Design is a well engineered printer with a very promising future. It has a huge community that loves their DIY builds and is very well documented.

  • Build volume: Scalable
  • Extruder: AfterBurner
  • Enclosure: Open or Enclosed
  • Moving Gantry
  • Electronics: Duet3D / Klipper

DESCRIPTION

The Voron V2.4 is a light weight and compact corexy motion system with a superior design. The printer has a moving gantry /  fixed bed that utilizes four point z-axis belts which is very unique for a corexy. The design is easily enclosed and has a lighter moving mass which sets it up for high speed prints with beautiful parts. While the V2 is a great machine it’s probably not the best for first time builders but does have a build guide that some say is far superior.

Although the four Z-axis motors implementation and expansion board may be challenging for some there are many more builds much simpler to choose from that will produce great results. The Voron V2 has precision linear rails for the X- and Y-axes and dual-drive extruder. The design uses four independent z-axis stepper motors that are belt driven which eliminates z-wobble that most machines experience. The light-weight moving gantry design increases print quality with it’s belt driven system which makes this corexy 3d printer design a community favorite.

Voron 2.4 Specs

  • Light-Weight Carriage Design
  • High speed prints with fewer defects
  • Better at printing tall thin things 
  • Great community support on Reddit
  • Less moving mass of the extruder carriage

Voron 2.4 Build Volume

Voron 2.4 3d printer kits are available in three sizes:

  • 250mm x 250mm x 250mm
  • 300mm x 300mm x 300mm
  • 350mm x 350mm x 350mm

BEST COREXY 3D PRINTERS 2021

The advantage the Voron’s fixed bed and belted z-axis that the moving mass isn’t at the top of the printer. While most 3d printers print objects at the top of the machine, the Voron’s fixed bedMoving gantry travels down to the bed. This mechanical arrangement keeps the moving mass towards the center of the machine This configuration makes the design more stable allowing for faster movements and 3d printing.

Blackbox Multi-Tool 3D Printer Toolchanger Platform

BlackBox ToolChanger Platform

While there are many open source 3d printer designs available, most of them are limited to specific 3d printable plastics. The Blackbox was designed and created by Marc Schömann of Layershift.xyz, who has a different approach to 3d printing with multi-materials. The Blackbox is designed to be a flexible platform for multitool fabrication. The multitool / multimaterial manufacturing platform for printing highly exotic materials and integrated assemblies.

Water Cooled-Toolchanger

The Blackbox was designed to produce high-end parts that challenge most 3d printers. The Blackbox 3D printer is a fully open source design that uses water-cooled printheads and a direct drive toolchanging system. The water-cooled setup offers more precise thermal control that’s more reliable and consistent. These factors are the secret ingredient to high quality 3D printing.

Most common 3d printers are limited to printing single materials and colors. The blackbox has a different design goal. The Blackbox design aims to provide a machine that can produce high-end parts from a range of many different materials.

  • Build Volume: 300 mm x 300 mm x 275 mm
  • Full enclosure
  • Direct drive toolchanger 
  • Water-cooled toolheads 
  • Belted  Z-axis
  • Automated leveling and calibration
  • Price: $2,900

Belt Drive Z-Axis

The belt-driven Z-axis has a 1:10 pulley reduction that allows the bed and layer height to precise movement  The frame is made from 4040 t-slot profiles and can print up to five materials at a time with the toolchanger.

Water-Cooled Tool Heads

The water-cooled tool heads are exchangeable cooled passively by the tool bank or the x-axis. While the tools use Bowden tube setup, the X-Axis carries one direct driven Extruder for flexible materials and uses a laser to keep the print area warm. The XYZ-axis all use linear rails and the  X-Axis uses a lightweight carbon support.

We first discovered RailCore Labs and the open-source corexy design at MRRF 2019. The Railcore 3d printer was designed while Tony Akens and J. Steve White were discussing an idea of a 3d printer with linear rails on the x,y and z-axis on Reprap IRC.

The Railcore uses 15mm frame extrusions and M3 hardware that brings down the cost. 15mm Extrusions use m3 hardware is much cheaper compared to m4 or m5 hardware. Although 15mm extrusions and m3 hardware may be less rigid the printer gains it’s rigidity from the reinforcement of the side panels. Many more design decisions were made to make the printer build as space efficient as possible while maximizing build volume. The printer build gains it’s rigidity

It is a well thought out design that has verity of CNC machined upgrades to pimp your printer. The prints that are made from the machine are absolutely beautiful. This 3d printer build is most commonly found using the Duet Wifi to power the system. The print quality is spectacular with it’s high precision 0.9 degree steppers. The pros of the Railcore corexy is:

  • Linear Rails on X,Y and Z-axis
  • Enclosure
  • 15mm extrusions to reduce the price of BOM
  • All-metal parts
  • Space & Cost efficient

While a toolchanger option isn’t currently available you’ll probably see a design oneday. Tony Akens explained in a fb post that the Railcore wasn’t designed for a toolchanger. RailCore Labs plans to retro-fit the E3D Tool Plates but it’s not built for toolchanging. Tony goes on to suggest that one would have to modify the printer and change how the RailCore works. He explains that bolting on components is easy by design but may complicate the RailCore bed leveling. He suggests that the Jubilee is somewhere in between the RailCore and the E3D ASMBL but has future plans to work with Joshua Vasquez the creator of the Jubilee.

CROXY CROSSED GANTRY 3D PRINTER

Designed and built by Wes Cherry

CroXY is a fully enclosed 3D Quadrap printer with a crossed linear rail gantry design, direct drive extruder and a kinematically mounted bed that moves in Z with three ball screws. Although this printer isn’t exactly a corexy it does utilize the same kinematics.

BEST COREXY 3D PRINTERS 2021

WHAT IS A QUADRAP MOTION SYSTEM?

The Quadrap mechanism is similar to a corexy but one or two extra stepper motors. It’s a cross between a core-xy and the ultimaker’s XY mechanical arrangement.

  • X- Axis
  • Y-Axis
  • X2-Axis or Y2-Axis / Both X2 abd Y2-Axis

The crossed members at the print head carriage allow low moving masses because none of the motors (X,Y or E) are moving with the extruder carriage. The corexy’s belt stretch issue is minimized when scaled up but resistance may increase.

  • Minimized belt length
  • Increased Resistance

Complete CoreXY Kits vs Self-Sourced BOM Part Lists

While many designs are available in complete corexy kits, some open source 3d printer designs are currently still self-sourced, meaning that builders will have to source individual 3d printer parts and get it all together which results in complexity as some parts may take long to receive and increases the chance that one might order the wrong part number.

Community Contributions & Published 3D Printer Mods

As more 3d printer mods and upgrades are increasingly announced in community groups and forums newly published designs that tend to be open-source and contributors announce their next printer designs such as anti-wobble lead screw nuts and belted z-axis drive mechanisms. 

While some corexy designs are familiar to others it’s a great environment for the community as design options and functionality evolves. There’s more opportunity for designers and contributors to make their own mark or be the first to design their own unique versions of an idea from one printer applied to a newer 3d printer platform. Design concepts and unique features inspire the development of open-source 3d printers.

BEST COREXY 3D PRINTERS 2021

Cantilever Bed vs 3-point Bed Leveling

While many of the original corexy printers used cantilever beds, carriage wheels or smooth rod the newer and better corexy published designs are now using linear rails and have adopted more functional mechanisms such as belted z-axis, toolchangers and non-planar 3d printing concepts such as 3-point bed leveling or triple z with kinematic coupling bed mounts for tilting print beds for perfect bed leveling.

Although the simplicity of older corexy reprap printers were less technical and easier for newbies, the increasing number of options and features can easily be adopted from corexy design platform to another, which has exponentially inspired contributors as they work to identify or fix potential issues or increase overall print volume.

3D printer designs such as the HyperCube use a cantilevered bed lifting mechanism which is fine for what is now considered a smaller print bed size. For example, most earlier designs have 200mm print beds but newer 3d printer options are available with larger bed sizes as many 3d printer platforms average around 300mm x 300mm beds and increasingly push the limits of build volume to 500mm if not larger. 

Heated Bed- DC vs Mains Powered Beds

While older corexy designs used DC-powered heat beds newer machine platforms are implementing mains-powered heat beds which allow users heat build plates much faster, however there’s nothing to stop you using a DC bed on a Voron or a mains bed on a HyperCube. It’s just wiring.

Build Volume- Scalability vs Reliability

While some designs scale up well beyond 300mm and other print volume sizes most 3d printer designs are offered in standard bed size options many people have moved away from the common 200mm bed size. Although, a smaller bed size reduces issues such as bed leveling and simplifies printer movement of a machine’s motion system movement.

BEST COREXY 3D PRINTERS 2021

Dual Z vs Triple Z

While earlier corexy 3d printers used the more common cantilever bed lifting mechanism which utilized a single stepper motor 3d printer with a dual Z axis lead screw setup mechanical layout which also worked well. However, there are plenty of Hypercube and D-Bot mods that implement dual-Z or linear rails or other components that increase accuracy and repeatability.

BEST COREXY 3D PRINTERS 2021

Thingiverse vs Github

There may be more mods available for the HyperCube and D-Bot style designs, but staying current with mods and other design alterations can be messy as previous users downloaded or contributed on platforms such as Thingiverse which is increasingly becoming more and more outdated due to inadequate search results and depreciating usability. Designers and contributors have migrated to platforms such as Github to download or share files which results in a much more organized approach that keeps the community up-to-date with design revisions. 

Rods vs Linear Rails

Many of the earlier 3d printers were designed around cheaper mechanical parts such as carbon rods or stainless steel smooth rods which were once commonly used and recommended. As the cost of linear rails become cheaper and cheaper due to the economy of scale and increasing number of buyers and large volume production of manufactures and suppliers. 8mm steel rods and linear bearings are slowly being somewhat phased out but still used on cheap kits found on Aliexpress. 

8-Bit vs 32-Bit Electronics

The 8-bit Marlin based boards such as the classic Ramps 1.4 have also been abandoned for more functional and customizable control boards and firmware that use 32-bit electronics with 24V Power Supplies and better stepper motor drivers like the Duet3d board. These control boards offer better documentation, support and large communities of technical users that share methods and firmware code to configure almost any 3d printer you could possibly design.

Customizability vs Availability

If you are looking for a cheap way to get started, building open source kits like the HyperCube and D-Bot is a good way to get started as you mod and upgrade your printer to a more functional machine. It’s much cheaper to build as you recycle or reuse parts like linear rods, lead screws and bearingsThe availability and access to mods miscellaneous parts with multiple design iterations.

Building a HyperCube or HEVO (Hypercube Evolution) can be quickly built which will get you started 3d printing as quick as a week spending on experience and mechanical knowledge some 3d printer designs can take months with the large number of parts and unfamiliar mechanical parts which may need more skill to assemble correctly. For example, corexy design options such as the Voron 3d printer can be a steep learning curve as one adventures off assembling the large number of 3d printed parts that may or may not fit together depending on how components were printed or choice of filament.

The Rat-Rig V-Core 3 is a much simpler core xy design with less parts and a straight forward build guide. While both the Voron 2.4 and V-Core-3 have linear rails which new users maybe challenged to properly align the linear rails.

Hevort vs Rat Rig

The HeVort printer is currently available by self-sourcing parts from the BOM parts list. Many builders would prefer to buy a complete kit with all the components instead of sourcing everything on my own.
