Need some help printing in Laywood

[entomophile 9]

I have been trying to make some prints on my UM2 of the UM robot in Laywoo-D3 on the normal quality defaults. I have tried at 190°C and 210°C (100% fan, 100% flow, 2.85 mm filament). I have tried with a 60°C bed and no heated bed. Each time the nozzle gets clogged and the print fails. I am not leaving the material in a hot nozzle. I clean the nozzle, get the laywood flowing nicely, and immediately print. Each time comes out like the picture. Any ideas on how to get this stuff to print? I know the wood fibers are up to 0.35 mm but I have read where people have successfully printed with 0.4 mm nozzles. Between the clogs and how easily the stuff snaps, I am starting to regret shelling out big bucks for this stuff.

PS-filament is feeding just fine, no skipping or grinding.

I had lots of problems initially with woodfll from Colorfab, which I assume is similar to laywood my problems were greatly improved by increasing the layer height.

From memory it was more than 0.2 or maybe even 0.25 after this it printed very well, the finish is on the rough side anyway with woodfil - I guess its all about keeping the filament flowing at a good speed.

hope this helps

Thanks for the advice. I printed at 190°C with a 0.2 mm layer height and got ONE good print. Two other attempts after that failed. Maybe I'll try again at 0.25 mm but I've had enough of this stuff for today. Back to some PLA prints for now.

Laywoo is tricky to print with a .4 nozzle it's possible but you'll get a lot of clogs...

One trick i learned from using woodfill fine (which is more compatible with .4 nozzles) is to keep a good constant speed and to avoid many retractions.

For laywoo someone on the french forum did some intense testing and came up with the following values:

temp from 185 to 245°

Flow 130-140%

Fan 70% layers stay soft 100% is better
