I'm new to the Milltronics forum. Wondering if anyone can help. I have a 1999 MB-19 with Centurion 6 controller. I'm getting poor "choppy" surface finishes in softer materials like aluminum and copper. But harder materials like steel and tool steel surface finishes are pretty good. The spindle bearings are just replaced and brand new. Same situation. Any ideas?
Thanks in advance for any help.
