printbus... great tips...
i certainly think you could be on to something with the cooling fan and the actual temps.

With the filament. I chose the same filament for both tests, so temperature could of course make a difference, but i dont think filament should.

Also, ive always read that doing the outer permiter last was better.. that is not true? I do the outer first on my FFCP and it looks great of course... Ill try that too.

I will recheck all the idlers again (i had it really dialed in before i changed the x carriage to cloughs printed one for ABL etc.

Lots to look at here.

I just wish Flashforge made a bigger one
