Topic: Gray filament

Hi, I just recently assembled a Filastruder and I am about halfway through cleaning the auger/barrel using the provided ABS pellets. I noticed that all of the filament which is coming out has been gray, and it doesn't seem to be lightening up. I was wondering what I should do to fix this?

I have been extruding at 180C, at a current<1A. I've only owned this Filastruder for less than a month, and have not used it to produce any filament (aside from the material I've been using to clean it).

Re: Gray filament

Hi I have my filastruder v2 and is the same I try extduding at 160  grades, at 170 grades and 180 grades and in all the cases all the time the natural pellet change to gray

Someone have an option, O was reading that is a configuration problem, but someone know how to configure or uodate

Re: Gray filament

Look at the pictures of the pellets, and the final print in this thread: http://www.soliforum.com/topic/15657/co … -colorant/

Is it similar to that?  If so, it's normal that the final print has a different appearance than the raw pellets.  Look at what happens once you add colorant though further down in that post (green).

Re: Gray filament

Thanks so much I'm gonna try just other question how I can change the amperage I try many times but it consent changes that 1.5 and it say that it possible needs 2 amp

Re: Gray filament

On the stall control board there are two dials. One limits voltage, the other limits current.  For ABS though you should not need more than 1.5A unless something else is wrong elsewhere (either in assembly, too low a temperature, or starting it too soon after it reaches temperature).  Some material has a higher viscosity like PETG so those materials could need more than 1.5A, but for ABS 1.5A should be more than you actually need.  Keep in mind the stall control board is limiting amperage to protect your motor/barrel and other parts.  You don't want to twist your barrel, or strip a gear in your motor's gearbox.
