This is project of Foldable CNC mill. The idea was to make CNC machine with fully adjustable workspace. You can put it on your table in kitchen and make some ornaments on corners or hang it on your front door and engrave your house address and after that when you finish your work you can easily disassemble it and forget that you need some extra space for big and heavy CNC machine :)

What you need to build it: 2x gate_holder.stl 2x main_gate_holder.stl 2x cover_slider_Y.stl 1x main_slider_Y.stl 1x main_slider_Y_MiR.stl 1x XZ_cross.stl 1x SliderX_1.stl 2x Slider_Z.stl 1x Z_spindle_holder.stl 1x Z_engine_holder_stl 2x butterfly.stl 4x support.stl Depends on spindle you have (I have cheap Verto 135W hand mill) 1x holder_vero.stl 1x holder_verto_2.stl

Spindle holder part has a lot of holes. It is possible to use it with different spindles, lasers or extruders.

You need also: 5m pipe 25mmx1mm (4x1m, 2x0,3m and 2x0,19m) 300mm of M6 threaded rod. 36x 626zz ball bearing (6x19x6) 6x 624zz ball bearing (4x13x5) for tooth belt 2x F6-14M thrust bearing (6x14x5) for Z axis 3,5m of GT2 6mm tooth belt 3x GT2 20 tooth pulleys 4x 42mmx42mm stepper motors 0,5Nm with 5mm shaft 1x CNC shaft coupler (5mm/6mm) 4x small bar clamps

Screws: (cylindrical, hex socket head screw) 12x M6x20 8x M6x30 4x M6x40 8x M6x45 2x M5x15 4x M5x20 4x M5x25 8x M5x35 2x M5x40 2x M5x45 4x M5x50 4x M5x60 16x M3x12 Small philips head: 6x M4x25 hex head: 2x M5x50

33x M6 Nuts 32x M5 Nuts 6x M4 Nuts

I have had some issues with slipping main gate holders and I have used sandpaper glued to small part of gate holder like on photo.

To lock tooth belt I have used small pieces of cutted plastic clamps.

I have used GRBL with Arduino nano and 3x StepSticks to drive my machine.

Here you can watch movie from tests :) https://youtu.be/5AQQKVzxxB0

2016-02-08 Updated Z_spindle_holder.stl - it is more rigid now :)

2017-03-30 There are so many questions in comments and in private messages about redesigning something to fit your parts that I decided to share Inventor project on google drive: https://drive.google.com/drive/folders/0B-ExPzdxcHOwV0o4eWRkbkVDdXc?resourcekey=0-PbTebK7kT22MLuvQNyNjRA&usp=sharing
