To fix the bed use 2mm longer M3 screws for the bed and i used nut to mount the bed, because there are no thread in the laser cut plexi stuff. Use the trapesoidal nut adapter 3d printed part, to mount the leadscrew to the X idlers. Use the prusa manual to create your printer BASE The differences: Use the coupler to mount the trapezoid screw to the Z motor axis It takes about an hour by hand but much cheaper. Use the 3030 BOSH extrusions to build the frame if you buy 3030 V slot extrusion you have to cut the 4 M5 threads yourself into every extrusion. Cutting files is into the prusa zip files (frame) Get the neccesery 6mm thick 4 plexi frame part. Īditional parts: print 2 pcs from this adapter: I AM going to skip mechanical building instrcutions because it is almost the same as on the original prusa. i have printed most of prusa parts from the web and some additional parts many M3 screws not counted the amount :(, mainly M3x10, M3 20, M3x25, M3x40, M3x30ġ set For Prusa i3 MK2 / MK3 3D clone printer Btech double gears K2E5
M3x5.4x1.8mm A2 STAINLESS STEEL SQUARE THIN NUTS DIN 562 Mk3 Mk52 Spring Steel Iron Heated Sheet Hot Bed Platform (i recommend the original prusa ones for PLA is not working well, later ill test for ABS and PETG) use blue tape on it for better adhesion)
#Arduino mega pin configuration how to
Here is how to use:Ģ x320mm rod 2 x330mm rod and 2x 370 mm rod it is better if you buy stainless steel It is possible to use ATX PSU from old PC-s. Radial Turbo Blower Fan Cooling Fan 50X50X15mm 5X 28Ncm Nema 17 Stepper Motor 0.4A 1.8° 4pcs TMC 2130 v1.1 (so you dont need to solder it for yourself) MK52 hotbed I used 24 Volt editon but now it is possible to find 12 V ones which is better for ramps It is mainly the electronics, i am using RAMPS 14, and 12 V for now. I will only describe the parts i changed. I decided to create my version of Mk3, and i try to built it as cheap as possible. There are so many Mk2 clones but not MK3. I really liked prusa i3 printers, and i fell in love with new features, of the mk3. I am going to update this instructable it is possible i lmissed parts.
