steel nozzle, wood filament, and Lack enclosure

This past weekend I put together my Lack Enclosure on my MK3. I completed it all besides the plexiglass since I had to order some online. I printed a quick raspberry pi camera mount and it worked fine. I then got a roll of wood filament from Amazon yesterday, so I decided to install the steel nozzle and try out the wood. I've always used Pretty PLA settings on slic3r and I kept it. I tried to print a small jewelry box, and while the brim looked perfect, the first layer of supports did not stick well to the bed (see photo). I played with the z height a little bit, I washed the bed with soap and water, and I increased the nozzle temp to 218 degrees. The first layer worked well, but in the middle of the print I ran into a bad layer. I let it finish, and when I pulled it off the bed the print broke in half at the bad layer. Any suggestions, or experience with first time users of a steel nozzle and/or wood PLA?

Re: steel nozzle, wood filament, and Lack enclosure

The wood filaments I've played with have a tendency to intermittently clog my 0.4 mm nozzle, leaving gaps in layers. Reading the filament fine print I've seen the common disclaimer Wood Filled filaments are not compatible with 0.4 mm nozzles; 0.6 is the common minimum listed with most of them, a few wood filament manufacturers state 0.8 mm minimum. Filamentium suggests 0.5mm minimum. ColorFabb is the only maker I've found that suggests their filament will survive a 0.4 mm nozzle.

ps: one suggestion is to increase flow to 110% to compensate for the occasional clog.
