Split Pulley

I was doing my head in trying to find out why I was skipping steps running a job in poplar. After finding the problem occurring during an air cut I knew it wasn’t a hard spot in the material.

Add some manual resistance to the Y-axis I noticed the plastic pulley rotating at a different rate to the aluminium hub. I removed the pulley and found that the plastic had split.

Time to buy aluminium pulleys!
