Rather than try and master an untested plastic, I think I will shift gears and go back to PLA. Has anyone had success with PLA from a vertical filastruder?

The temperature of the hotend drops because the fan is controlled with the same switch as the motor.

To my knowledge, no one has attempted HDPE.

Looking at the pellets I think these may be HDPE pellets, not ABS. Has anyone tried extruding with HDPE?

Another strange note, when I start extruding the temperature of the hot end drops by about 10 degrees.

While I wait for reply's I am going to try a higher nozzle temperature. Will post the results.

I am trying out an ebay pellet vendor who sells pellets left over from an extrusion molding machine. I am noticing some blobbing and I think it maybe related to the temperature of the hot end. Basically, can someone help me understand:

If the filament is coming out too thick is the temperature a) too high or b) too low. I know I will need to dial in the temperature these pellets require blindly, as I don't know the specifications for the ABS pellets. Any advise on how to do this properly?

Thanks,
