So I think we all pretty much like ReplicatorG and its a great solid printer interface regardless of what you are running; from a MakerBot to a Duplicator 4X to a DIY RepRap it works great. Except that its so CRAZY slow at generating gCode. Well, I just found something that might help... next time you are slicing, go up to the gCode menu, select "gCode Generator" and click on "Slic3r 0.X - Experimental" and then slice as usual - it's way WAY faster!!
I did a side by side comparison and slicing with the normal "Skeinforge (47) - Legacy" setting took my MacBook Pro 34min while the new Slic3r 0.X setting took that same model 1min 12seconds. VERY COOL!!
Give it a try and see what you think... have a great day and remember; Keep Calm and GEEK on @ MakerGeeks! http://www.makergeeks.com/
