Just started using skeinforge as a slicer, looking for greater detail than slic3r can make. Slices fine, but when the build begins to run, it just dumps out way too much plastic making a gooey mess. I can actually watch the line feed in at a rate of probably a couple of meters per minute. I just calibrated skeinforge, as shown on youtube (http://www.youtube.com/watch?v=s3iXnLo0kYs). but it still is just pouring out the plastic. I don't have a problem with slic3r doing this. Any ideas? https://reprap.org/forum/read.php?154,239591,239591#msg-239591 Thu, 21 May 2026 15:47:12 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?154,239591,241816#msg-241816 https://reprap.org/forum/read.php?154,239591,241816#msg-241816 nophead Skeinforge Sun, 01 Sep 2013 15:45:48 -0400 https://reprap.org/forum/read.php?154,239591,241807#msg-241807 https://reprap.org/forum/read.php?154,239591,241807#msg-241807 gwfami Skeinforge Sun, 01 Sep 2013 14:49:39 -0400 https://reprap.org/forum/read.php?154,239591,241804#msg-241804 https://reprap.org/forum/read.php?154,239591,241804#msg-241804 gwfami Skeinforge Sun, 01 Sep 2013 14:41:49 -0400 https://reprap.org/forum/read.php?154,239591,241795#msg-241795 https://reprap.org/forum/read.php?154,239591,241795#msg-241795 I triple checked the speed and dimensions tab and didn't see anything that might have caused the problem. What I did do, however, was to change the filament packing ratio from .4 to 1.5 (dimension tab).

Here's what it did.
ratio = 0.4 - really squishy, lots of plastic gobs, print head like a John Deere tracked tractor plow through plastic.
ratio = 1.0 - not as squishy, not as much plastic ooze, print head not like a hand plow through plastic.
ratio = 1.5 - no squishies, no plastic ooze, print head now not plowing at all.

I'll keep you up to date, the test print is supposed to take another 2 + hours to finish.

I would think that these two parameters are the ones you need to check. I think at least one of them appears in two places for different situations. I'm not at my PC now to give you more definite answers.]]> jbernardis Skeinforge Sat, 31 Aug 2013 20:01:35 -0400 https://reprap.org/forum/read.php?154,239591,241578#msg-241578 https://reprap.org/forum/read.php?154,239591,241578#msg-241578
If you send absolute E gcode to firmware configured for relative E it extrudes ever increasing amounts of plastic. However your E values are far too big anyway. They increase at a rate similar to the distance traveled whereas the filament should be fed into the extruder much more slowly that it comes out.

Since skeinforge is known to work correctly you must have some setting wrong. AFAIK the only things that affect it are on the Speed tab and the Dimension tab. When feed rate and flow rate are set the same Skienforge works out the volume of plastic needed for the specified layer height and filament width. It then uses the filament diameter to work out how far to feed it for a given XY move.]]> nophead Skeinforge Sat, 31 Aug 2013 17:42:28 -0400 https://reprap.org/forum/read.php?154,239591,241561#msg-241561 https://reprap.org/forum/read.php?154,239591,241561#msg-241561 gwfami Skeinforge Sat, 31 Aug 2013 15:55:31 -0400 https://reprap.org/forum/read.php?154,239591,241414#msg-241414 https://reprap.org/forum/read.php?154,239591,241414#msg-241414 nophead Skeinforge Sat, 31 Aug 2013 03:56:36 -0400 https://reprap.org/forum/read.php?154,239591,241366#msg-241366 https://reprap.org/forum/read.php?154,239591,241366#msg-241366
What could cause the high E numbers?]]> gwfami Skeinforge Fri, 30 Aug 2013 20:28:11 -0400 https://reprap.org/forum/read.php?154,239591,241363#msg-241363 https://reprap.org/forum/read.php?154,239591,241363#msg-241363
The E numbers you have seem very high - so the problem is in the slicer, not the printer - it's just doing what its told.]]> jbernardis Skeinforge Fri, 30 Aug 2013 19:56:51 -0400 https://reprap.org/forum/read.php?154,239591,241355#msg-241355 https://reprap.org/forum/read.php?154,239591,241355#msg-241355 nophead Skeinforge Fri, 30 Aug 2013 18:18:38 -0400 https://reprap.org/forum/read.php?154,239591,241330#msg-241330 https://reprap.org/forum/read.php?154,239591,241330#msg-241330 I went in, calculated the e offset, setup the carve and other parameters, entered the filament volume, and a few other minor things. I left most of the parameters alone.

Here's the first few lines of the g code. It's for a ring mustache (mustache ring?) from thingiverse called mo ring. Something simple to start with, I thought.

I just calibrated skeinforge, as shown on youtube (http://www.youtube.com/watch?v=s3iXnLo0kYs). but it still is just pouring out the plastic.

I don't have a problem with slic3r doing this.

Any ideas?]]> gwfami Skeinforge Sun, 25 Aug 2013 13:39:01 -0400
