Skeinforge Dwindle
From DEMOZENDIUM
Dwindle is a plugin to reduce the Feed Rate and Flow Rate at the end of the thread, in order to reduce the ooze when traveling. It reduces the Flow Rate by a bit more than the Feed Rate, in order to use up the pent up plastic in the thread so that there is less remaining in the ooze.

Operation
The default 'Activate Dwindle' checkbox is off. When it is on, the functions described below will work, when it is off, nothing will be done.
Settings
End Rate Multiplier
Default: 0.5
Defines the ratio of the feed and flow rate at the end over the feed and flow rate of the rest of the thread. With reasonable values for the Pent Up Volume and Slowdown Volume, the amount of ooze should be roughly proportional to the square of the End Rate Multiplier. If the End Rate Multiplier is too low, the printing will be very slow because the feed rate will be lower. If the End Rate Multiplier is too high, there will still be a lot of ooze.
Pent Up Volume
Default: 0.4 mm3
When the filament is stopped, there is a pent up volume of plastic that comes out afterwards. For best results, the Pent Up Volume in dwindle should be set to that amount. If the Pent Up Volume is too small, there will still be a lot of ooze. If the Pent Up Volume is too large, the end of the thread will be thinner than the rest of the thread.
Slowdown Steps
Default: 3
Dwindle reduces the feed rate and flow rate in steps so the thread will remain at roughly the same thickness until the end. The Slowdown Steps setting is the number of steps, the more steps the smaller the variation in the thread thickness, but the larger the size of the resulting gcode file and the more time spent pausing between segments.
Slowdown Volume
Default: 5 mm3
The Slowdown Volume is the volume of the end of the thread where the feed and flow rates will be decreased. If the Slowdown Volume is too small, there won't be enough time to get rid of the pent up plastic, so there will still be a lot of ooze. If the Slowdown Volume is too large, a bit of time will be wasted because for a large portion of the thread, the feed rate will be slow. Overall, it is best to err on being too large, because too large would only waste machine time in production, rather than the more important string removal labor time.
