Portable 3D Printer

Human: Can you speak Dutch? Then go to https://www.designuitinspiratie.nl/3d-printer/draagbare-fdm-3d-printer/ for a better presentation on my own website :-) Portable FDM Printer I wanted a printer that can be easily transported without being damaged in transport. So I made this printer :-) The housing is as small as possible while keeping standard print dimensions. This one can print 200x200x380mm. To keep it light, the housing is made from 9mm plywood. It's basically a square box with the printer mounted inside. You can make your own housing or frame. Of course, the housing is an advantage if you want to print ABS. Then I wanted this printer as fast as possible because there's not always much time, printing on site :-). Therefore, I used a Bowden setup and very light X and Y carriages. The vase printed in the picture is printed at 60mm/s in PLA. I want to test this printer with higher speeds but didn't have time yet. The red fan ducts on the side of the nozzle are not my own design (RoPa here on Thingiverse : http://www.thingiverse.com/thing:1264477). Because my printers are often connected to polluted mains, there's a simple mains filter built-in. This filter kills most EMF frequencies for the Arduino. The Atmel chip can do strange things 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 of an X2 and Y2 class so that if they die, they're guaranteed not to short out. 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, see the picture.
