A CNC mill is a pretty handy tool for rapid prototyping, as well final production of parts. I was recently gifted (very generously!) a 2418 CNC Mill. Woohoo! It’s a small DIY machine for cutting/carving detailed shapes in plastic and wood.
It took a few hours to assemble. I found I needed to refer to several sets of instructions to put it together. So I’ve tried to make a more comprehensive, one-stop instruction set in this post.
Overall dimensions of the frame are 340 x 330 x 230mm – width x depth x height.
In the box
Allen keys (supplied). I recommend a ball-end allen key, which makes it easier.
Paintbrush to brush off aluminium shavings left on some parts.
Put on some good ‘flow’ tunes. My recommendation is Lost Shapes by Waveshaper.
File the rough edges off the brackets.
Assemble the vertical frame (‘portal frame’).
Attach portal frame to base frame.
Assemble the table.
Install y-axis screw and motor.
Install the oblique supports.
Install Z/X axis.
Align the top support pedestals to be flush with the top of the portal frame (use a square). Tighten the grub screws on the top rod. Align the bottom pedestals to be 26mm from the top ones and tighten. Tighten grub screws on bottom rod. Check the ZX assembly slides smoothly from one end to the other. When it’s good tighten up all the bolts and check again.
Install the stepper and idler bearing, ensuring everything is aligned.
