If a cut doesn’t match the 3D preview, it’s usually a mechanical or electronic issue — please check the machine mechanically. Per the machine operating checklist: Machine Operating Checklist - Carbide 3D , the basic points of adjustment for a machine are:
-
Pulley set screws: Checking Pulley Set Screws - Carbide 3D — be sure to check all axes/pulleys (including Z on machines w/ belt-drive Z-axis, for an HDZ, check both coupler screws).
-
(for the SO3/4) V wheels / eccentric nuts: Tightening Eccentric Nuts - Carbide 3D
-
Belt tension (see the relevant step in your instruction manual, e.g., Step 5 Belting - Carbide 3D) Note that the X-axis motor is held in place on standoffs and if those bolts are loose this can cause belt tension issues. Also, belt tension for the Y-axis stepper motors needs to be even/equivalent on each side — a significant difference can cause skipping on one side eventually resulting in lost steps on both.
