Building A Corexy 3d Printer – You may be asking yourself, why would I build a printer when there are so many 3D printers available for purchase? …and that’s a good question. There are many printers out there, and at first glance most seem to be very affordable options.
But these “cheap” printers are not without their flaws. You can buy a printer cheaply, but it won’t work the way you want, and that’s more frustrating than spending “real” money on quality components to begin with. I have already purchased 2 of these printers and spent at least the original purchase price, re-upgrading the hotend, control board, MOSFET, printer bed glass, etc. bought
Building A Corexy 3d Printer
Most cheap 3D printers are also available as kits, so you’ll end up messing up the printer anyway. So why not build a high-quality 3D printer from scratch?
My New Custom Corexy Printer Design, The Fusebox3. Just Need To Finish Up The Bom And I’ll Be Ready To Order Parts And Build.
Building your own 3D printer can seem a bit difficult if we don’t know what parts are needed. However, if we go step by step and follow this guide, we can order all the quality components we need and enjoy a project with a high-quality large printer that will open up many possibilities for future projects.
Of course, we have a caveat: this printer uses 3D printed parts. Either you already have a 3D printer for printing, you can order the parts here in the webshop, or you need to use a 3D printing service.
(The hot bed rails on the side of the printer are 336 mm long, which requires a large print base (arranged diagonally). If you have a 200 x 200 mm print pad, these are the only 2 parts you need for the external Must send print, otherwise can be purchased in my shop).
Noise level measured during printing. This is important when printing large volumes and working throughout the night. At 50.5 dB it is barely noticeable when the printer is in another room. Printer design in general. Works fantastic, can be scaled on all axes. Physical and network bed alignment. For this you need a board with 6 drivers. Linear rails in all axes, Z axis with belt drive.
Homemade/designed Corexy 3d Printer
V1 engineering printers are not as well documented as CNCs. Building a printer is surprisingly much more difficult than building a large CNC. It’s basically DIY, ask questions in the forums and we’ll help you out and hopefully add to the details here over time.
This printer was developed using open source code. There are so many variables that go into making a printer to your liking that I can’t cover everything. I’ll list how I did it, it’ll be the easiest way, and from there I’ll try to give you tips and tricks on how to adapt it to your needs. For example, I use BLTouch. You can use whatever you want. However, please note that you will need to change the extruder mount accordingly and edit the firmware accordingly.
Control board, you need at least 6 drivers. I used the SKR Pro with Marlin, an example configuration is available in Marlin Builder. Here is the optional driver 2209. ~$147
5 steppers, Z steppers can be quite small, X and Y steppers are basically XY steppers should be larger so speed is not an issue. Steppers Good Shop ~$57

For 12-24V power supply, make sure all components comply with this voltage. 45W+ for printer and heating plate, heated beds require 300W or more when unplugged. Example ~$25
The frame can only consist of profiles, profiles and panels. If you’re a hardcore fan, you could also build it just out of panels, but I’ve found that’s too seasonal to have an accurate printer. Profiles and panels are easiest to produce if you have a CNC. When using plates and profiles, use M3x10mm screws and T-nuts, and profiles only use the included brackets (M5 and T-nuts).
Hardware, linear rails use M3x8 (plus a step bracket marked “8”, “Y” step type). Minimum 3 per +1 rail (16), maximum 1 per 25mm +1 rail (30+).
M3x10mm for rafters (19), X-rail connection (4), rail support blocks (24), frame pressure parts (20), additional panels (~80). ~150 pcs+
Custom Large Format Corexy 3d Printer Build
Cut all rails by 2-3mm to give you room to adjust the square. A tight fit on a profile offers no advantage. If you use panels, you can leave 5mm or more space on the Z-profiles to allow for cable routing.
Totals here can vary, around $750 if you buy everything new. If you have parts that can be reused, you can quickly reduce the price.
In my opinion it’s best to start with the back of the frame, build it as accurately as possible and use that as a reference for the entire rest of the frame.
The X dimension (from left to right when looking at the printer) is the most important. This allows the X-rail to fit into the printed parts.

Cut the straps so far that it is difficult to pull them through the slots. If they don’t hold, insert a piece of thread into the loop.
Aligning the frame takes the most time, and the more perfectly you do it, the easier it is to get parts with accurate dimensions. This essentially consists of measuring the diagonals of all the faces of the frame and adjusting them to the best of your ability.
I spend most of my time checking the diagonals. For example, print a large square on the bed, measure the diagonals and make sure I print the squares. This directional adjustment is the position of the changes the position of the can be moved up or down. With a few test prints I can achieve 150mm of XY (flat), YZ (tall front to back) and XZ (tall left to right) within 0.1mm. Unless you really If you are printing size critical functional parts, you can skip this step. Be careful not to overtighten the straps as you should barely hear the noise. Since it is doubled, the 1/16 turn of the tension screws will provide plenty of movement. You can Stop your stepper easily if the belt is too tight.
The firmware is located in the builder for SKR Pro, V13RP_V4_SkrPro_2209-2.x.x.zip, configured for 200x200x200. If you change the size, you must also change the bed size and/or the cell size and/or the Z-height. Then recompile and stitch together.

Some resizing rules. Your X dimension must be a multiple of 25mm. All other axes can have any desired length. In CAD the spacing of the rail holes can look a bit strange, which in CAD is only cosmetic. Apart from the rails, which are usually sold in multiples of 25mm, there are no functional issues.
