This halo is designed for the 250ZL series of the RailCore II printers. Click here for Railcore II ZL series info

This halo works only with larger (magnum) pulleys.  The number of mounting holes and their placement are slightly different on this halo as compared to the original halo, to specifically accommodate the larger (magnum) pulleys. The larger (magnum) pulleys are now placed inside the halo perimeter where as the original (smaller) pulleys were placed outside of the halo frame. 

This halo is NOT compatible with the original RailCore II (small) pulleys.  If you have any questions about compatibility, please ask prior to ordering, as we are not responsible for ordering errors.

The halo is a large structural element that helps align and rigidize the idler pulley mounts, motor mounts, and printer frame.  In keeping with the style of our other Railcore products, the halo is custom milled in-house, with a beautiful shiny face and sides, and chamfered edges.

This part replaces the idler pulley mounts and the motor mounts with a large, one piece structure.  It has access holes to allow easy adjustment of the top 4 corner cubes and a large open center for easy access.

We recommend having an assortment of M3 bolts/screws, in the 8mm - 16mm range, on hand to attach any accessories to the halo, as needed.

The 250ZL halo overall dimensions are approximately 532 x 413 mm (21 x 17 in).

We take great care to provide the highest quality milled aluminum parts, but minor tooling marks or superficial surface marks may be present from time to time.
