Making a mini 3d printer using C-Beam aluminum

The wire was bundled up and I started putting all the remaining parts together.

After calibration, I proceeded to test run the machine.

The plastic roll holder is located at the back and is simple.

Next is the arrangement of the control circuit mounting position and wiring. Initially, the control circuit is arranged on the back of the C-Beam.

To make wiring easier I lowered the control board position.

The C-Beam structure is often used with nema 23 motors, so to use it with nema 17 motors, I had to design a separate motor mounting structure and at the same time be able to change the clearance between the motor and the C-Beam to suit different lead screw lengths.

I looked for several ways to mount the 3D printer head to the chassis and this is the option I chose, this option allows me to change the distance between the printer head and the chassis, it is more flexible.

I used available pcb copper foil and mica sheet to make the printing table.

Another solution to a failed printhead mount.

 I had some spare C-Beam aluminum frames that I wanted to use to make a mini 3d printer. I designed a 3d file to figure out how to lay out the XYZ axes and how to connect them together.

 This structure requires the use of aluminum angle brackets and hex flat head bolts:

 However, when tightening, the bolt head was worn out, after trying again many times and still had the same problem with the connection not being secure, with slight play. I redesigned another right angle bracket by removing the protruding edge.

 I proceeded to put them together.
