New cloud has inconsistent X wobble

It’s quite possible that the engrave head is moving on the gantry.

With the power off, open the lid and if the module is cool enough, grab the laser module (or engrave head) close to the work, wiggle it and see if the module is loose on the gantry.

I would also attempt to wiggle the work area and finally confirm that the work hold-downs are sufficient to prevent the work from moving while engraving is happening.
