Any chance we can get this version of Slicer up on the web for AstroPrinters, either as an update to the current Slic3r version or as a separate slicer?
I have been playing around with the stand alone version and they have made some nice improvements, mostly noticeable in the support material (important until Astroprint supports multiple extruders, having good decent with a single material would be really nice and the current versions of Slic3r and Cura on Astroprint seem weak here) and also some improvements (I think) to the infill choices.
This plus some other enhancements and claimed performance improvements which should help the AstroPrint back end seems like this would be a good update.
