I have, what seems significant to me, right movement at the lower Z carriage wheels. I don’t recall it being loose when I assembled. Today I ran my first test job on a piece of construction plywood. Towards the end of the job, when the spindle was moving left I noticed the bit kicking to the right and when going around a curve moving to the rear the bit would drag behind. After inspecting I noticed the nut on the lower left Z carriage wheel was very loose. I tightened it but there is still a good bit of movement. Is this normal? I’ll attempt to load a pic and video.
