Hello,
I'm printing with red PLA in an Ultimaker 3 Extended. I have printed with other types of PLA, green, blue and transparent and i haven't got problems to print. But now when I'm printing with red PLA I'm having some problems. I'm using similar parameters in CURA that I used in other pieces of PLA and I obtained good results, even I have used the same gcode in fifferent occasions and once i have problems and other times this not occur.
Sometimes while a piece is printing the extruder don't print material, the print proces continue but the amount of material that is deposited is reduced an finally no material is printed, the aparience of the piece when this occur is the next:
When this occur the filament in the feeder appears worns as it looks in the image:
At the same time in the part of the filament just before to entering in the print core appears a widening as you can see in the following images:
I don't know why this widening is produced and why reason the print cores don't extrude material. I don't know if for some reason the extruder get blocked and while the feeder continues pushing the filament into the print cores appear this widening or if this may be a problem in the filament that no allow enter the filament in the print core.
Someone can help me?
For other hand other problem that I have found with red PLA is that, in some occasions when change the extruder and the print head come back to the print zone a little amount of material is being printed and this filament its deposited in the walls of the piece forming a burr:
What can produced this anticipated or this drip? At the same teperatures with other PLAs I haven't got this problems.
Thanks!
