FireSlide™ MakerSlide Nema 11 stepper mount (16T)

Function

MakerSlide mount for Nema 11 5mm shaft stepper motor that drives GT2 belt running through MakerSlide top channel using a 16T pulley. Provides M3 mounting holes for optical endstop Mount also has slots for inserting screwdriver to adjust belt tension. The height of the stepper mount provides clearance for extrusions passing over it, which maximizes the carriage traversal distance for a given MakerSlide length.

A provided, optional spacing washer can assist with exact GT2 pulley alignment.

Requires

  • M5x10mm screw (2)
  • M5 extrusion nut (2)
  • Nema 11 stepper with 5mm shaft (1)
  • M2.5x8mm screw for stepper (4)
  • GT2 16T pulley (1)
  • GT2 belt (twice as long as your MakerSlide)
  • RECOMMENDED: Optical endstop (1)
  • RECOMMENDED: M3x12mm screw for endstop (2)
  • RECOMMENDED: M3 nut (2)

Assembly

  • The provided stepper washer can sometimes be useful in getting the exact spacing necessary for proper alignment between the GT2 pulley and the MakerSlide channel
  • Use the notch in the mount to reposition and tighten the pulley as needed
  • Steppers run hot (125°F is typical) and you may want to anneal your mount by running it for 30m or longer without belt tension. Annealing will relieve stress crystallize the pastic for stability under stress.
