Reservoir Heads
Cold Flow is our term for fluid or emulsified (non-filament-based) materials which are deposited at room temperature, with or without UV Crosslinking.

Settings
Some settings for the EMO-Type heads (like temperature, prime/unprime values) will vary, depending on what material you are printing with. Nozzle diameter should accurately reflect what nozzle you have loaded (1.6mm is default) AND what path width you sliced for. Temperature commands will be ignored by heads with no temperature control. Having said that, here are our default shipping settings:
| Settings | EMO, VOL, KRA, COD, VCD, KCD Heads and New KR2 (17mm Tubes, Various Gear Ratios) |
SDS, CSD, VSD, and CVS Heads (Various Tube Diameters, Standard Gear Ratios) |
