Hi guys…I built my LR2 last spring and with the help of this great forum I’ve been able to resolve every problem which has come up so far, but his one has me stumped:
When cutting out a part it seems to cut “inside the line” on the first pass, but only on the right side of the part. The remaining passes are right on the money and I’d have a perfect part if not for the unsightly rabbet on the top right edge. This hasn’t mattered for most of my projects to date, but the time has come to fix it.
A bit about my setup - LR2 on 4’ x 6’ table, mini rambo, Estlcam, the following example was cut with a 1/4" 2 flute endmill (though I’ve had the same issue with other bits), 8mm/s, 0.10" DOC. Now some pics:
good from afar
top and left sides - no problem.

right side, notice defect goes away when cutting to the left
defect comes back for the rest of the right side

I would really appreciate any thoughts you have on what could be causing it. And for the record I double (and triple) checked the tightness of my grub screws.
