[MakeLV] Next Open Hack

Sat Jun 11 21:59:23 CDT 2011

There is no user friendly way to automate multiple prints on the ABP.  What
you have to do is load an stl, generate the gcode, then go to the gcode tab
and select all, then copy and paste multiple times.  It was great for
printing the 30 parts for the stick puzzle!
http://www.thingiverse.com/thing:6689  The problem at the moment with the
ABP is it doesn't handle tall prints too well.  Tall prints tend to get
knocked off as the belt pulls up slightly when the nozzle collides with the
part during printing.  Some people are having good success with custom made
titanium belts though.

You can get a ToM to be pretty quiet if you adjust the stepper controller
voltages right.

Oh and the scanner is a Polhemus FastScan

about $30k I'm hoping to get my head scanned with it on Monday.  :)
