build frame-gantry

≪ overview | frame-table ≫

Steps

1. Prepare parts for this subsystem: Parts Americas, Parts Europe
2. Start with the outer frame.
   • For each corner attach the angle brackets with M5x10 screws. Mount short ends first.
   • Aim for tolerances of less than 0.5mm (0.02") basically making sure there are no gaps or overhanging edges.
   • T-slot nuts are asymmetric, think ahead how to load them best.
   • Try to align all brackets as parallel with the T-slots as possible.
   • Build on a planar surface.
   • The T-slot nuts can be side-loaded into the slot, pre-loading is not necessary.
   • The T-slot nuts also have thread locking glue pre-applied and do not require lock washers.
3. Then attach the left and right y-rails with the planar brackets, M5x08 screws, and M5 washers (use washers,unlike some images show).

Checklist

• Is the frame planar?
• When you measure the diagonals are they the same?
• Have you used the shorter screws (M5x08) for the planar brackets and the longer ones (M5x10) for the angle brackets?
