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.

thanks i am going to look into the rollers tomorrow.

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.http://www.talkshopbot.com/forum/att...id=30886&stc=1

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

Glad you found the problem.

I have been having the same tooling marks on 3D carvings. I tried the suggestions above and found that the root cause for my Buddy PRS Alpha was the z pinion not being adequately greased. I took an automobile grease gun and liberally applied grease and ALL TOOLING MARKS disappeared. I hope this may help someone who is having similar problems
