Will be posting questions in G-code corner on how to stop the wax blocking the holes in my punched tape reader soon. :rofl:
you use a pointy crayon to poke it through

It's taken me three hours to figure out how to use the toolbox in there!
cad can be a bitch to get into, keep pressing though, by the time you have finished your build you should be ready to design a time machine and catch yourself a hendrix gig

try your best to draw your finished machine to absolute perfection... it gets really tedious finalising your drawing, making sure everthing is going to fit just the way you exspect it to

most of us have to do at least a little bit of re-design halfway through our build due to an over sight in our drawings... its not to bad if you have the machinary to do the re-work, a nightmare if you havn't
