Description

This is a 3d printed CNC Machine, it has a similar design philosophy as the generic 3018 machines.
It uses a mix of mechanical and 3d printed parts.

All the 3d printed parts are shared as STLs, and a Bambu Lab print file has also been been attached.
The picture of the Final assembly is shown below

ASSEMBLY

Assemble the Frame in the given picture
Attach bearings to the Y-Axis and fit is inside the frame in the given pictures
1. If the bearings are tight, use sandpaper
2. If the bearings a loose, take tissue paper (as a filler) and surround the hole with it and fit the bearings.
The 380 mm extrusions run across right to left, giving the width of the machine
The 340mm extrusions run along the x-axis
The 280mm extrusion run from bottom to top, giving the height
Then attach all the corner bracket pieces with M4 SHCS screw (6mm length) washer and t nuts.
Attach the vertical supports, or the Long L bracket with M5 screws and t nuts
Attach the Side mounts for the y axis.
Attach stepper motors with M3 SHCS length 20mm screws with 12mm spacers(3d printable)
Attach the 8mm lead screw end support bearings
Attach flexible couplers to both the motors
Attach the 2 8mm rods and the lead screw
Now, fit bearings on to the z axis assembly
and also attach the T8 nut on it with M3 SHCS screws of length of 6mm
Now, complete the whole Z-axis assembly with lead screws, 8mm rods.
Now, let's make the bed of the CNC
1. Attach 4 2040 extrusions along their length with the help of long brackets
  shown below. 4 of them can be used in conjunction to connect them.
2. Attach the bearings blocks on the adapter block with Philips round head screws length 6mm, then attach the block onto the bed with M4 SHCS screws of length 6mm
3. Attach the T8 Nut coupling and the X-axis limit switches with the help of M4 SHCS screws, length 6mm
  Also attach the T8 nut onto the coupling with M3 SHCS screws of length 6mm
Now attach the stepper motor to the adapter bracket with M3 SHCS screws of length 6mm
Then attach the block to the frame with M5 SHCS screws of length 14mm
also attach the Flexible coupling
Now attach the linear motion shaft support to the frame, Make sure they are equally spaced from the stepper motor and not so far away from it.
Now attach the supporting bearing block(KP08( of the 8 mm lead screw on the other side of the stepper motor with M4 SHCS Screws of length 8mm. with 4mm 3d printed spacers between the frame and the block
Now attach the 8mm rods, the lead screw, the bed on to the rest of the machine in a systematic manner
Then attach the adapter for the X-axis limit switches, making sure they align with the part that presses on them on the bed.
Now attach the limit switches on the y-axis, x-axis, and z-axis.
That's it!
Make sure you oil up the smooth rods, the lead screws, the bearings and especially the extrusions the y-axis is riding on!
