I had a similar problem during one my first overnight prints. It turned out that Windows did an update, AND a restart. Since then, I always disable the internet connection.

MatterControl can rotate, scale, and mirror. It's free and easy. I pretty much just use it to rotate models then export and use Slic3r, but it can also slice and print as an alternative to Slic3r/Pronterface.

I also like this possibility, very cool idea. I remember Jin was working on something like this.

Since we all measure our filaments prior to slicing, how important will it be to make sure that all of the filaments are within .01-.02mm of each other?

Hey jimc I'll give rsilvers' drive another shot over the weekend. I am using ABS for the drives with an 80% infill. They seem to work fine when printing PLA. The first time I printed ABS (using 245*) I melted the you-know-what out of the stock drive. I had Karen send 2 more and I trashed both. I fin...

Have you tried printing this drive with close to 100% infill? http://www.thingiverse.com/thing:267137 It works very well and as long as your cooling fan is working correctly. You will get better results with this drive than the stock one. Yes, rsilvers' model is great, love the way the filament tub...

Ummmm, yeah. :?[/quote] Maybe I should have been a bit more specific when describing the problem I have with ABS filament drive. The drive isn't literally breaking. It's the groove that holds the hot end in place that deforms, allowing the hot end to move. It would seem that this is a critical area ...

Thanks guys. I think that I'll still have it (and the motor mount) machined. I'll get back to the group when something else breaks because of the aluminum parts.

Hi Guys I seem to be going through filament drives like crazy. With ABS it's about 2.5 drives per roll. Typically the failure is on an overnight build when the model comes loose, apparently sticks up too far, and gets clobbered by the hot end repeatedly, resulting in a loose groove in the drive for ...

Rick, Thank You!
