Ender 3 first layer of ESD PLA printing on raft fails
The gap between the raft and the first layer is too large (you need to switch to expert mode in Ultimaker Cura to see the values of the option before you can change them) and the hotend is too hot (normal PLA generally prints at 190&nbsp;&deg;C, ESD PLA prints at higher temperatures; you could aim for 210&nbsp;&deg;C as a start), This makes it difficult to precisely deposition the first layer on the raft as the nozzle drags the hot filament causing inaccurate first layer deposition.

Furthermore, PLA generally doesn't require a raft to print the part. The Creality Ender 3 has a rough bed (like a BuildTak surface), you could print directly onto the bed surface.

Source states:


  Extruder Temp:  Typically 210-220°C.  ESD PLA is a filled product and
  has a higher melt viscosity vs. unfilled PLA.  Therefore, it is
  sometimes necessary to print at higher temperatures than your standard
  PLA to allow the resin to flow properly.


This implies that a hotend of 220&nbsp;&deg;C mot not be hot enough, in that case the filament is too cold and viscous and gets dragged because the gap is too large.
