whis is normal sound?

[ksn-arts 84]

sometimes the engine makes a strange sound when retracting. is this normal? print speed is not high and 30 mm s 15 mm sec print small objects.Friends tell me what all the same temperature table is optimal for printing small items and objects from plastic Pla. i use 60 c

Sounds like your filament is too tight on the coil. The rolls of filament are way too tight when reaching the middle to end of the coil. See if the squeeking stops if you unwind a meter of filament off the coil first ?

60c bed temp for PLA is perfect.

Thanks maybe it rubs against the casing string with black wire? you do yourself an alternate mechanism extruder or work with a standard?

I dont use these spools anymore. I buy Faberdashery filament, this is supplied loose, Not on a coil. I basically leave the filament on the floor behind the printer and it unravels itself fine.

I will take a photo of the spooled filament for you that has been removed from the spool, so that you can see how tight it gets.

and if the coil placed on the floor? thread running smoothly into the extruder?

 

[skint 61]

Yes that`s correct. The standard filament guides on the back of the ultimaker make the filament enter the feeder too tightly, and the ultimaker filaments on coils are way too tight when nearing the end of a coil. I have reduced my underextrusion a lot since using uncoiled filament.

Faberdashery filament is supplied loose like this. At first i printed a filament holder to use with it, but I find leaving it on the floor works just fine.

 

I also use the standard feeder/extruder etc, no modifications yet. Working well.

thank,and dust from the floor? you did a filter?

 

[skint 61]

No dust filter. My filament is covered in dust and a LOT of cat hairs but I tend to clean out the feeder area every 5-10 prints just to make sure its not too dirty. I personally think worrying about dust is a little over-kill

and I also have a kitten running around everywhere:)))

Hey Skint,

I will hijack the thread with another related question - did you try long prints with the Faberdashery spools simply lying on the floor? Like, 6-12 hours prints? My fear is, that the coils will intertwist and overlap, preventing the print.

 

[skint 61]

hey Shurik

My longest so far is about 14 hours. When I know it is going to be a long print, I check through the filament to make sure the approximate amount is free from twists. I have done many long prints, and had one twist :( so far.
