To mechanically check the machine, power up, install a 1/4" probing pin, jog to the center of the machine, then grab the tip of the pin and try to shift it — it should be rock steady — if it isn’t, investigate and check where things are allowed to move.
A few other considerations:
are the tool/collet installed correctly? Make sure that stickout is minimized
wood quality — try surfacing off the material
toolpath options — for smaller designs use a more acute tool
figure-ground reversal — your design is a bunch of shalllow lines, many of which are redundant for describing the insignia
