Kit Options

Belt Path

A printer’s motors can be offset at different heights so that the belt routing runs a straight belt path and don’t have to be twisted. But this belt routing path would also mean that on one side of the gantry the belt would have the teeth on the side of the idler wheel which wouldn’t run as smooth and could lead to artifacts within printed parts.

Mechanical Arrangement

The crossed belts configuration found on the SolidCore  y-axis must be completely perpendicular to each other to prevent any mechanical binding.

Linear Rail: Supported vs Unsupported

A crossbar made from u-shaped aluminum extrusion is used as a support for the linear rails. Depending on the rail length if the  y-axis has an unsupported linear rail it could possibly lead to deflection. The load of the belt paths have to be balanced along the running plane with the pulleys. An unbalanced load can lead to the belts trying to slip off the pulleys and premature wear of the bearings.

Linear Rails

The standard SolidCore design uses MGN12 Type H linear rails.
