When using Wood PLA, I had to make a few adjustments. The main issue that I encountered was clogging. The wood grain that is embedded in the PLA just seemed to clog up a 0.4mm nozzle very quickly. To resolve this, I switched to a 0.5mm nozzle. Additionally, I had to increase the nozzle temperature. On average, I run wood PLA about 10-15 degrees hotter than standard PLA.
Once it is finished, the results are pretty cool.
