For some crazy reason I decided to build another CNC hot wire cutter. This is going to be much larger than the one I currently have. It's going to be one cubic meter in size. I don't plan on cutting anything that large, but the dimensions will provide a steeper cutting angle and allow cutting more parts in a single run.
The frame will be primarily be 2040 extruded aluminum. I'll be re-using the electronics box from the current hot wire machine. It will be configured to use both a tension spring and bow for the wire itself.
In a total overkill decision, linear motion will be guided by MGN12 rails.
There will be two frames (X/Y and U/V axes) mirrored to each other. 1/8" aluminum will be CNC milled into the necessary brackets and mounts. 3D printed parts will round out the build for additional bracing, foot mounting brackets and wire management.
I can make all of the STLs and DXFs available if there is interest.
Let's get this project rolling...
Cutting the aluminum parts.
A little bit of cleanup on a Scotch-Brite wheel and these are ready.
In the background the 3D printers were cranking away making more parts
Mounting brackets for the feet
Making wire management clips
Corner braces (gyroid infill)
