    Some of what you might be seeing is the different colors in the black walnut that the flash picked up, but i am still not happy. I have new pinion gears all the way around and a new z motor. I am currently cutting a Texas Ranger badge and not happy with it at all. I am going to try and re-cut the finishing tool path again tomorrow and see what happens.

    One thing that is often overlooked when chasing down apparent Z issues on a Buddy is the condition, adjustment and cleanliness of the powerstick V rollers and pinion. If the rollers are not adjusted properly the table surface can flex up and down as weight shifts from table movement.

    Good one Gary...

    Power up the control box & wiggle the table in all directions...check the powerstick pinion while you're at it.

    Nothing like owning up to your own mistakes. The only reason I am posting this is to help someone else not make the same mistake in the future. I watched shopbot’s video on how to change the pinions and how to achieve the same position on the shaft. I thought that I did this correctly but was wrong. The gear protruded out to far only a tiny fraction of an inch and I believe that it was causing me to loose my z ever so little. After conferring with tec support we figured it out and correctly positioned the gear. I have just done a new carving with no issues.

    Congratulations - It might kick your butt the first time, but after you learn you'll know what to look for. (Hopefully anyway...)
