perhaps the feed rollers need an adjustment beyond just the spring tension? Most of you guys in this forum seem have this info already, but the specs I got from Felder when I tuned up my AD741 were as follows:
The infeed roller should be 0.020" below the bottom most rotation of the carbide insert.
The outfeed roller should be 0.028" below.
+/- 0.004
Maybe if the infeed and/or outfeed rollers are set too high they're not engaging the material properly to pull it through?
