Spoiler Board facing is not flat (Saw-teeth effect)

 cnc-milling, evo, ts_evo_usage, ts_fab_usage, ts_pro_usage, usage

▶  Description of the problem

When doing a facing, instead of nice and flat surfaces, your machine leaves a "wavy" or "Saw-teeth" surface.

▶  Possible origins

This is caused by the spindle not being perfectly square to the frame. It is very common and easy to fix with a calibration of the machine.  

▶  Solution

Follow the calibration method described in the Calibration Methodology to fix this issue.
