I’m not sure if this applies to our comparatively intelligent microprocessor-based printers as well. @Whosa_whatsis posted a detailed comment over on @Stephanie_A ’ post at: https://plus.google.com/101448691399929440302/posts/UJ91Ek5R4be
If it does, it sounds like it’s very similar to Marlin’s advance option.

I’m still undecided if the g-code interpreter is the only place for this can be handled. I believe the slicer could be made to perform the same functionality. A slicer forced to understood acceleration parameters could then modify how to extrude to minimize blobs…

off to look at the marlin code.

@David_Grossman As I mentioned in the other thread, Marlin has had an (experimental) algorithm for this (called “advance”) for some time, and there’s currently a pending pull request to add a similar algorithm to Slic3r.
