Hey Cesar,

in its stock configuration, the Onefinity Standard Series with their connectors with missing serious cable management and even strain relief and the unshielded stepper cables may have unexpected position change issues during operation due to connector problems, or due to introduced EMI. See search results for plunge workpiece for examples.

See

and

for details on the possible causes of such issues.
