FILAMENT VARIATION
Does it seem like there’s too much or too little plastic being used in your prints? This can
happen when your filament doesn’t look or behave exactly how the slicing engine expects
it to. Sometimes 1.75 mm plastic filament is actually closer to 1.65 mm or 1.85 mm. Your
extruder can handle this range of sizes, but the slicer requires an accurate description of
your filament to create a good toolpath.
To compensate for filament variation, you can create a custom profile. See Using Custom
Slicing Profiles at www.makerbot.com/support/new/Desktop for instructions.
1. Unspool a couple of feet of filament and use a caliper to measure it at several
dierent points. Average out those measurements and note the averaged value.
2. Create a custom profile and click the Edit Profile button to open the config file in a text
editor. Then find the correct “feedDiameter” setting. You will see two “feedDiameter”
settings, one enclosed in each of the extruder profiles. Change the first
“feedDiameter” setting if you are printing using the right extruder on your MakerBot
Replicator 2X and change the second “feedDiameter” setting if you are using the le
extruder.
3. Save the config file and use your new custom profile to print.
If you are having trouble with the amount of plastic being extruded and the value entered
for “feedDiameter” is accurate, look at the “feedstockMultiplier” setting. This setting
compensates for any dierence between the calculated volume of plastic going into
the extruder and the actual amount of the plastic coming out of the extruder. Like the
“feedDiameter” setting, the “feedstockMultiplier” setting appears twice in the config
file – once in each of the two extruder profiles. When changing the “feedstockMultiplier”
setting, make sure you choose the setting for the correct extruder.
