I’m having trouble milling long, horizontal lines. It seems there’s a consistent upward arc as the mill travels across the right side of the machine. The machine also “slows” near the center of the cutting arear. There’s also slight bowing and arching when milling rectangle designs.
I’ve read about more powerful PSUs, adjusting chain sag, and feedrate. However, before I go down any of those paths, I’m curious if anyone can diagnose based on the photo below. The red area is the latest example.
