I seem to be getting regular partial nozzle blocks using the wood PLA filament. The first few items I printed with it were absolutely fine, but I’m currently doing a run of multiple parts and have had a couple of blockages. Now, even after trying to clean the nozzle as best as I can, the parts start fine, but by the end it looks like the nozzle is partially blocked and under extruding quite a lot. They’re not massive parts, only about a 5 hour print. After the first bigger block, I switched to a new nozzle, so there’s no different type of filament that could be causing issues. Is this a known problem with the wood filament? Is it worth trying a cleaning filament? I’ve never felt the need for one before now. ---

Wood filament is highly abrasive. So a lot of problems are solved by using a hardened nozzle. But that’s not usually a clogging issue. It does tend to clog more than normal filament. You might want to try increasing temperature. Also a lot of people like to use a .6mm nozzle but still with settings for .4mm. Might have to play with flow to get results you need. -S ---

I did just try one with an extra 5 degrees nozzle temp. That one blocked completely! I have just got some new nozzles, including some 0.6mm ones to try.When you say use a 0.6 but with 0.4mm settings, do you mean literally just change the nozzle and nothing else, or tell cura it’s got a 0.6mm nozzle, but only print with a 0.4mm line width? ---

I’ve heard of some materials getting too hot and basically burning and that causing clogging. > [@davidE1A](#): > > do you mean literally just change the nozzle and nothing else, or tell cura it’s got a 0.6mm nozzle, but only print with a 0.4mm line width? Just change the nozzle. No change to the settings. Print same as you would with a .4. The idea is that the wood filaments don’t flow quite as freely and having the slightly larger nozzle makes up for that. (BTW, I haven’t done it personally, but I think it’s been discussed on this forum a few times. Probably a year or two ago. Try a search) -S ---

One thing I forgot to mention. Have you tried drying the filament? Wood filament can be especially susceptible to absorbing moisture. -S ---

I haven’t, no. But I’m fairly sure I have no other signs of moisture - no popping, blobs or anything. It prints fine, just the line width gets thinner. But, I am now thinking it might just be that the nozzle has worn out already (especially if the wood filament is that harsh). I had to pause the wood pieces to print a couple of things with normal pla, so I put a new nozzle in, and the first print going back to the wood is looking ok again. Also, I read somewhere that when extruding the filament (when loading), if it curls up coming out the nozzle (which mine was after trying to clean it) then that’s a sign of a worn nozzle. Part on the left was an early print. The middle, the last complete print it managed, which was after doing about 15 of these. On the right, with a new nozzle again. ![IMG_20230926_123411](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/c/9/c92e8e2196c0e463c5264b2a1c86ee0f76b92f58.jpeg) The few tiny gaps I can live with, so I think I’ll see how long this nozzle lasts (I have 50 of these to print!) and then try the 0.6mm if it wears out quickly again.
