Stringing (Ultimaker Original)

[LePaul 321]

Hi

I was reviewing some Tips and Tricks and have a few questions.

I've been lowering my print temperature to about 200-208C and keeping the print speed at 45-50. (travel speed 150). I'm still seeing a lot of stringing, especially on prints that have multiple objects.

I am printing with Ultimaker PLA blue (2.85mm)

I seem to have trouble with extruding material if I go below 200, thus why I am finding myself in the 208 C range

Extraction is enabled. No heated bed plate

Using the 15.06 version of CURA

Should I print faster and hotter? Say 220C and double the print speed to 100?

Print one object at a time?

I'd try lower and slower but, again, trouble extruding when i go lower in temp

Thanks!

Hello Iepaul

Stringing happens more when the temperature is higher. So try to print at 195 or 190 C and with speed 30-40.

When you bring down your speed you don't get any trouble at all.

Also make sure your nozzle exterior is relatively clean, sometimes some residual stuff on the side of the nozzle 'drags' the newly extruded material along creating thin string. I find if you have a lot caked on, set it to 90C and it peels off like a skin. (you can do a cold pull too while you're here. )

Good tips....I'll try slower and if i can get the extruder to play nice under 200C
