Portable 3D Printer

For an updated version on my own website, go to https://www.designuitinspiratie.nl/3d-printer/draagbare-fdm-3d-printer/ Portable FDM Printer I wanted a printer that can be easily transported without being damaged during transport. So I built this printer. The housing is as compact as possible while maintaining standard print dimensions. This one prints 200x200x380mm. To keep it light, the housing is made from 9mm plywood. It's essentially a square box with the printer mounted inside. You can create your own housing or frame. Of course, the housing is an advantage if you want to print ABS. Then I wanted this printer to be as fast as possible because there's not always much time to print on site. Therefore, I used a Bowden setup and very light X and Y cars. The vase printed in the picture was printed at 60mm/s in PLA. I want to test this printer with higher speed but didn't have time yet. The red fan ducts on the side of the nozzle are not my own design. Because my printers are often connected to polluted mains (there are welding, milling, and grinding machines nearby), there's a simple mains filter built-in. This filter kills most of the EMF frequencies going to the Arduino. The Atmel chip can behave strangely under EMF stress. Normally I prefer a second ferrite coil but didn't have one. For the schematic, see the picture. Note that the capacitors need to be X2 and Y2 class so if they fail, they're guaranteed not to short. C1 & C2 need to be of class X2. C3 & C4 need to be of class Y2. Also, this filter needs to be in a metal case (see picture) and must always be earthed. The controller is an Arduino and a Ramps 14 running on Marlin. I included the marlin.ino in the Zip file. For information about configuring Marlin, consult: http://marlinfw.org/docs/configuration/configuration.html To hold the Teflon tubing in place, I used a gland nut. The original tube holders I have don't work very well for some reason. If you have questions or think I forgot something, feel free to ask or comment.
