Hey Guys! I got my new G0704 2 days ago and am really loving it except for one thing. The speed controller on the spindle motor does not seem to be stable. I ran the break in for the spindle bearings just like the manual stated but the speed jumps all over the place while the spindle is turning. Ive seen spikes as much as 500 RPMs when I start spinning at 1000. For example Last night, I started at 1000, it jumped to 1100, 1300, 1490 then back to 1100 then down to 980.
Its not just the tach thats wrong either the spindle is changing speed too. I havent had time to call grizzly yet. Do you guys have any ideas?
