Flashforge finder printing with wood pla

Hi folks.

Got my finder a month ago and i am loving it so far.

Just to experiment i got 2 different flavors: wood and metal.

Metal totally clogged my extruder so had to disassemble the printer and ended changing the nozzle; with wood i’ve been able to finish just one print, all the others start but at a certain point, like some minutes after start, the printer stop extruding filament but still goes on with the task. I tried increasing the temperature but my last print clogged the nozzle. Should i just change brand of filament (using formfutura wood filament) or i am doing something wrong?

With normal PLA i print with no issues.

Cheers

What slicer? Slow the print down with wood and also look at retraction settings.

I am using the stock slicer, flashprint, but also tried simplify3d with the same results. I am printing at 80mm/s, is it too much? At what speed should i set it up? And what do you suggest for retraction?

Thanx for answering

Yes, way to fast! I “wood” start out at about 35-40mm/sec overall. I don’t recall my retractions off hand but pretty standard PLA so maybe 1.2 at 1600mm/min.

Thanx mate, will give a try hoping not ho have to disassemble my extruder again

What brand of wood filament? Also would be good to google printing with wood filament to see what others are doing. You can kind of get an idea of things to watch for.

I think speed was your main issue.

I am using formfutura brand. While the normal Pla is great and never had any problem, the wood instead. I would never imagine that speed would give clogging issues. Will make a test today.

Cheers mate.

I generally print fairly slow anyway but I think the idea on wood is that trying to extrude to fast (faster printing) can cause the actual wood particles to get jammed up because they can’t get through the nozzle that fast.

Think about trying to pour Olives from a jar with a smaller opening … go to fast and they can bunch up at the opening of the jar. Slower and they can fall out as you pour. Odd comparison but it just popped into my head!

Might be odd but gave me exactly the idea about what you mean thank you very much!
