💡 Why do solid aluminum frame bars stay more accurate than cheap stamped steel brackets?

Constant heat exposure and belt pull speed quickly twist low grade sheet metal. Dropping in heavy gauge extruded rails keeps guide paths dead straight for crisp output.
- Snap in fresh support walls that kill lateral shake during fast accelerations
- Fit rigid crossbars to take heavy tool heads without bending under weight
- Trust precision mounting blocks for steady smooth travel along every axis
- Load up sturdy fasteners to keep geometry locked tight through long prints
