repeating lines in carving - z axis losing steps

I just finished setting up my workbee and when using the end mill the finish and calibration seems spot on. However, when I did a carving test I'm getting a regularly repeating line that looks like the z axis is skipping. I made sure everything was tight and still happening. Different files and cam softwares produce the same result. any ideas? Thanks for the help.

Hi Eric,

This is called a tramming issue. The best way to tram a router is to buy a tramming tool like this: ++https://www.machine-dro.co.uk/edge-techn...

This will measure how much out of tram the router is. You can make your own version with an indicator dial on a rod.

To Tram the X, this can be simply done by moving the router mount up or down on the left or right side. If you use the Height Reference tool, this should get it perfect: Assembling Your Original WorkBee Router Mount

To Tram the Y, also known as the nod, is more difficult. Minute adjustment is needed. Therefore adding something as thin a tin foil underneath the top/bottom of the Z-Bracket to get the correct adjustment would work.
