When extruding from pellets, it needs to be far drier than it does when printing.

After making abs colorant i dried it before extruding, just lined a baking tray with foil and pored it in then put it in the middle of the oven for about 50c for 3 to 4 hours.

I found out that I got good results with 2 filament guides, one 1cm away from the extruder at the same height and another an inch down and 4 inches from the end of the extruder.
I also found that the fan should be directly pointed at the filament RIGHT AS IT COMES OUT of the extruder.

Do you think I should make a fan guide to point the air at the tip of the extruder and what is the best guide for the filament?
My temp is set at 155C and I dried the PLA so there it is not wet.
The filament is better than last time but not good enough since the filament either sticks the the nozzle and clumps up or becomes really thin.

i'm extrude pla  and i 'm using 2 heaters band one in the middle of extruder  at 171°c and another on the nozzle at 176°
and it work fine

I think I'll try drying the PLA and running the extruder at 155C. Thanks for the quick response. I though it would take a few week but It only took 1min for a reply.

Luckily since we extrude slower it isn't as important as it is for industrial extruders, but the drier the PLA, the better.

155C sounds about right. There is no perfect temperature as there are different types of PLA, and colorant can effect melting temperature also.
