It was pretty painful honestly, but like all good problems, it ended up being a great learning experience.

It’s an issue with square tooth belts that at certain positions, the tooth of the belt either slips into groove on the pully, or doesn’t (catches on corner of tooth) Same position on axis/same number of steps, but one layer the tooth slips in, one layer it doesn’t. Causes layers to shift randomly by fractions of a millimetre on one axis only. Usually manifests on structures with smooth vertical sides.
