Hey Phil, got a follow up question-- so I calibrated the potentiometers, which helped a great deal. I carved an octagon on the machine using a 1/8" 2F upspiral bit. Used the default settings for soft maple. 711mm/minute & 0.7mm depth.
When moving north west the cutting got significantly louder. Is that normal? I adjusted the feed to 600 mm / minute b/c I thought it may have been moving too fast. Loud again, but couldn't tell if it was better or worse. Any ideas on why only certain parts of the carve with be louder?
