1)Clean cutter but dry tissue left inside
2)Probe gets broken
First, the only way to remove stuck parts is pulling them out, or replace the whole component.
Here are some
Make it go round, and pull it out by a pliers.
2.Remove the rough edges
Went rounds between removing rough edges, dry cloth, little wd40 on tissue, dry wipe again.
Done 4 or 5 times, and it moves in & out smoothly
1.Clean machine esp. remove metal filings by the brush inside the package
2.For machines that has been used for years, open it, clean inside parts, and lube ball screw and cross rail
