Cube 3D printer community

Thank you Dan for detailed info.   Although I am not sure a about the melting point being different with various colors.  I don't  think the chip makes a difference. I really think cube 3d 2nd gen.  Is using a bit of a thinner filament  than standard 1.75. I will try your suggestion and get the filament that you are using. I also agree the alignment  of the filament is important so the stepping motor and pulley has an easier time feeding it in.   Storm,  i agree with Dan do not remove anything  especially  the fan. For PLA printing i actually add an extra small fan the cool the print bed...  Just remove the cover,  and adjust the pulley.  (i did end up getting a better 7mm wrench but you could use the one it came with).  It's  the first bolt in the front. You alse have a clogged extruder/ head it sounds....   That is easy to fix.  Just use to supplied tool to unclog  the head with.
