Ok, so after the problems with the CNC in Kamp-Lintfort last week i found a way to export
my sketches to the CNC:In Solidworks make a 2D sketch out of your 3D part
Export this 2D sketch as PDF
Import the PDF into Rhino
Lay the parts in the right layers (inline, outline, pocket, etc)
Join the polylines in Rhino
Export it as DXF
After found this workflow it was very easy to mill the parts for my mill.
Used about 1.5m^2 of 15mm multiplex:
The joints works just fine, so the first assemble of the y-axis worked very good:
Finaly the trapeziodal-screws and the 10mm rods arrived, but my colleague who is a pro on the lathe was in holiday.
Ok, lets get fit on the lathe again. I learnd this 10 years ago, so it was not such a big problem:
The last mechanical thing to do was to find a way to mount the endswitches for min and max to the axis.
I get a bunch of these:
For the mount i desigend some angles in solidworks and printed them out on an ultimaker (Quick and dirty ;))
With all parts ready i started the assembling. I forgot to make some fotos. but here is the
complete finished mill:
I planed to use a smoothieboard for the electronics. Not much to say here, i just followed the
very good documentation on the smoothie-website.
I connected the motors to the board, using the output of extruder1 for the second X-Axis-Motor.
The endswitches are connected like explained in the docu. The max-endswitches aren´t connected at this time...
What i need to buy are some cable-chains. Till now the cables are just secured by some zip tie...
The setup for the smoothieboard was a kind out-of-the-box, just made some fine-justage.
For a first test i zipped a pencil on the z-axis:
Finaly, all works very good. The only negative point is, that the 10mm rods are not stiff enough,
so the z-axis goes about 3mm.
In the molding and casting week i used the mill to mill some foam (see Week 12).
Next task for the mill will be the composites-week, stay tuned :)
Till then, have fun!
