So, I’ve been getting some odd chatter lines in a few areas, and was wondering if anyone has suggestions on how to remove them.
I’m carving letters in relief, so they stand out by 1/4". To the left of some letters, I’m getting a distinct line of chatter marks, I’m guessing by the bit rubbing against the side of the letter. See picture below. It only happens when the bit is going one way, not the other, and it only happens once the depth gets to a certain point. The machine is calibrated and is working great.
I’ve tried both Easel and sending gcode from PicSender, same basic result (although in different places). Anyone have suggestions to eliminate this? I’m making a lot of these signs and it’s time-consuming to sand them out. Fortunately it’s soft wood, but still.
