How does this compare to the 3D preview in your file?
Usually if the actual cut doesn’t match the 3D preview the issue is a mechanical one. 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
-
(for the Pro) Lubrication of the linear rails: https://docs.carbide3d.com/assembly/linear-guide-maintenance/Linear_Rail_and_Guide_Maintenance_02-17-2021_v1.0.pdf
-
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. Measuring belt tension, squaring and calibration
