Black ABS

[34Ford]

, I will never forget the roll of White ABS that came with my printer... I haven't been able to buy as good as a white since, off anyone, INLCUDING Flashforge. The next white batch they sent me was an off white, and the batch after that was white, but more glossy white off colour. Their original white that came with the machine, printed Dry and perfectly.

The White I got with my machine was this amazing snow white, it was really really bright white.. the best white ABS I have still ever seen printed. I have bought dozens of whites now, and still can't find one as white!!
Every white I buy now is a little off, or bone colour.. man I just want pure white, like cocaine white!

You must have gotten some that is gone now, although I am new to these printers, the white that come with my Pro today is not a bright white.

I order one or 2 white rolls every fortnight, and I change suppliers every single time just in the hope I will find it again. It is the closest thing to a 'white plaster' print I have found, for someone like me that loves to paint, it's sorta like my favourite abs to print and paint.

Couldn't find the "change advice" post you talk about but I'll tell you what I've been doing lately. I either added to or started a thread about cleaning clogged nozzles. That talked about heating up nylon in the extruder, then cooling it "some" and then extracting it. The semi-cooled nylon would drag out a perfectly shaped model of the inside of the nozzle, and anything left inside, would come with it. It works fantastically for me.

So, I now have applied that workflow to all my filament even when I'm not clearing a jam. Before I remove or swap a filament, say ABS, I set the head to about 110C and let it sit for a few minutes. Then I slowly pull that filament out with some needle nosed pliers. I grab the filament near the hinge and rest the tip on the top of my extruder body's surface. I then lift the pliers very, very slowly, by the handles. It's sort of like a lever with the pliers tip resting on the extruder and my hand lifting the handles. I lift the filament out mm by mm until it comes free. And, it's shaped like the nozzle's inside with a little tip that was left from the nozzles .4mm opening (or whatever diameter the nozzle is). I then know I got ALL of say, the Black, filament out. So if I put White in now, I have virtually no contamination of color and I know it's clean inside.

This is a shot of the nylon cleaning but it shows what the extracted filament should look like:

You mean 210C don't you? 110C and it won't even get soft????
