Printing With Flex...Help?

I'm trying out some Flex filament from Torwell.

I can get it to print, but it seems to collect some on my print head (Standard J-Head .4mm) and then drop blobs into the print.

My working settings are:

bed 70c
Tip 205c

Any advice on flexable filament may be useful. Never used it before.

Thanks,

Ive recently printed with some white ninja flex and found that gooey on the nozzle as well.
I cleaned it between prints. Its very sticky stuff.

I used 230degC for nozzle and about 60 for bed with just clean mirror glass.
It did ooze a bit and i had to watch for the start of the print to pull the ooze away.

Maybe a bit hotter to flow better and not get stuck to the nozzle?

I have yet to find any flexible material that does not ooze. Most of the flexible stuff i print holds well on glas with PVA glue.
The most limiting factor is a reliable extruder. I created my own[www.thingiverse.com], which worked quite well, but then a friend made a better one [www.thingiverse.com]
SInce each material has it's own range of temperature you will have to check for the exact type, or just try it out.
I found that you can get extremely good results with this [www.plastink.com]
It prints very much like ABS

Thanks All!

Higher temp did keep the filament from building-up on the nozzle.

However, I do think my current extruder is having trouble gripping the filament.

Again thanks,

Ive got a direct wades reloaded with no modifications for flexible filament and had to slow it down to 30mm/s to stop the ninja flex from bunching up.
And had to loosen of the grip on the hobbed bolt a bit. As it was just deforming the filament and deflecting the path a bit in the extruder.
I normaly print at 50mm/s for abs.
