Pocket carving not flat on bottom

[AlanDavis]

Your Z axis is not level.
I think this link can give you some ideas how to do it

Potential buyer inquiries about: leveling Z axis, dewalt 611 runout, and X/Y backlash

Please oh please don’t spend 70-80$ for a Precise Bits collet, its pointless. With the quality of the router and the lack of stiffness of the x-carve collet runout will not make a difference. I bought the elaire collets because i wanted 1/8 and they’re pretty cheap, otherwise i would have stuck to the dewalt collet.
