Hi guys, my first post here.

Just finished building this cnc plasma structure. Trying to get it dialed in.

I have nema 23 motors and rack and pinion.

Why is it so damn noisy?

It sounds like a vacuum cleaner with a bunch of rocks tumbling around in it.

I ended up sanding the 2x2's to make them smoother but it barely helped.

Its not nearly as loud in the video... but you get the point.

Everyone else's machines sound so cool, like electric cars and mine sounds like rocks in a tin can?

thanks!
