Recently, our extruder has a very strange problem.
When it extrudes PVC, it will produce a pungent sour smell.
![Shocked :shock:](./images/smilies/icon_eek.gif)
our tempature setting is 135
The extruded pvc cake has very rough edges and is very soft, as if there is a lot of air in it. Has anyone encountered this problem? Could it be the problem of the extruder screw? Many Thanks
Roger
