Don’t let anyone tell you you can’t print wood pla with anything smaller than .6mm nozzle and has to be steel. Printed two of these back to back with .4mm brass (stock nozzle) at 210 on the nozzle and 65 on the pei bed. Printed at 40mms and had at .24 lines. All you have to do is start with a slow print speed and a slightly faster flow rate. Make sure your nozzle is clean inside to ensure the wood chips don’t have anything to cling onto and you should be good to go.
