  1. Printing problems with red PLA

    The fan works correctly at all times. I have printed with red PLA again and I haven't got problems in 4 pieces, but the problem of non extrusion return again, I saw that and I stopped the impression when this happened and unload the filament, this time no appear widening, so the widening is produced by the heat of the printcore while the drive wheel push the filament into the printcore. Imeasure the diameter of the filament and this is about 2.80mm, it is right. I think that I have a defective filament in its composition or it has some impurity that obstructs the nozzle or causes the material not flow well and clog the nozzle finally. Now I changed the filament to green PLA and I haven't got this problem.
  2. Printing problems with red PLA

    Sorry, The parameters with wich I have printed are: - Print temperature 220ºC (also probe with 200ºC and 210ºC and obtain good results when the nozle does not lock) with inicial and final temperatures (when change the extruder) 5ºC under the print temperature ( 195ºC when I print at 200ºC, etc...) this is somewhat higher than the predetermined temperatures that appear in CURA when you set the print temperature. · Layer height: 0.2mm · Line width: 0.2mm · Velocity: - Print velocity 50 mm/s - Infill velocity 50 mm/s - Outer Wall velocity 35 mm/s - Inner wall velocity 40 mm/s - Support velocity 25 mm/s (PVA support)
  3. Printing problems with red PLA

    The PLA is a Ultimaker filament. I have mesured the filament diameter after the problems and, now, this is correct, the diameter is between 2'80 - 2'85mm, but I don't know if the diameter of the filament was greater in the moment that problems appeared and this causes blockage in the print core because the material does not enter, and then the drive wheel grind the filament or if there is another cause that block the nozzle and then the thickening appear due to the high temperature near the print cores and that the drive wheel contiue pushing the filament. There are any way to predict when this may occur? This is important because these problems waste a lot of time. The parameters with wich I have printed are: - Print temperature 220ºC (also probe with 200ºC and 210ºC and obtain good results when the nozle does not lock) with inicial and final temperatures (when change the extruder) 5ºC under the print temperature ( 195ºC when I print at 200ºC, etc...) this is somewhat higher than the predetermined temperatures that appear in CURA when you set the print temperature. · Layer height: 0.2mm · Line width: 0.2mm · Velocity:
  4. Printing problems with red PLA

    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!
