Making the Ponoko RepRap Y Axis Assemblies

PonokoYAxisAssembly-dsc04445.jpg

The Y Axis is the one that moves the X Axis assembly back and forth. There are three main components: Y Idlers and the Y Motor Assembly. The Y Idlers are possibly the simplest of all the RepRap assemblies to make, so we'll start with them. You'll need to make two.


PonokoYAxisAssembly-dsc04441.jpg

This is the collection of parts that you need to build a Y Idler Assembly (you'll need two of them):

  • A M8 70mm bolt (or as pictured, 70mm of M8 studding)
  • One M8 nut (or if you're using studding, two)
  • One M8 Nyloc nut
  • Four M8 washers
  • One 608 bearing.

<repeat count="2"> Attach the Idler Mount to the axle. If using a <part a="ifbolt">M8 70mm bolt</part>, put the head to the left. If <part a="ifstudding">M8 70mm studding</part>, screw a <part a="ifstudding">M8 nut</part> onto it. Then in this order, <part p="M8">washer</part>, Idler Mount, another Idler Mount, <part p="M8">washer</part>, <part p="M8">nut</part>.

Attach the Y Idler Bearing to the axle loosely. Add to the M8 stack a <part p="M8">washer</part>, a 3mm disc laser-labelled with Y1D, the <part>608Z skate bearing</part>, another 3mm disc, a <part p="M8">washer</part>, and finally the <part p="M8">nyloc nut</part>. Make another one and set these aside. </repeat>

Parts for the Y Drive Rod Assembly:

  • 500mm M8 studding
  • 4 M8 washers
  • 4 M8 nuts
  • 2 ball chain gears


PonokoYAxisAssembly-dsc04447.jpg
You'll need a <part>M8 500mm studding</part>.

Screw one <part p="M8">nut</part> down the studding until about 45mm of thread remains. Slide down a <part p="M8">washer</part>, the ball chain gear, another <part p="M8">washer</part>, run a <part p="M8">nut</part> down, slide a <part p="608Z">skate bearing</part> down to the nut, and follow it with another <part p="M8">nut</part> (see the next photo for the bearing and nut). Make it finger-tight.

On the other end of the rod build the same assembly: Screw one <part p="M8">nut</part> down the studding until about 45mm of thread remains. Slide down a <part p="M8">washer</part>, the ball chain gear, another <part p="M8">washer</part>, run a <part p="M8">nut</part> down, slide a <part p="608Z">skate bearing</part> down to the nut, and follow it with another <part p="M8">nut</part>.

There are three lasercut pieces needed here. Put <part p="4 M3">washer</part>s on <part>four M3 30mm screw</part>s and insert them into the 5mm Y Bearing part with the large (bearing-sized) hole, then the 3mm Y Bearing part. There will be a gap here where 8mm posts will go, then the 5mm Y Bearing part with the small (slightly larger than 8mm) hole. Slide on <part p="4 M3">washer</part>s and <part p="4 M3">nut</part>s. Screw them on just far enough that they won't fall off, for now.

Slide the Y Drive Rod's bearing into the hole in the Y Bearing Assembly.

The Y Motor Mount.


PonokoYAxisAssembly-dsc04458.jpg

The Y Motor hangs off the end of this assembly. When you make the second Y Motor Mount (<part p="four M3 30mm">screw</part>s, <part p="4 M3">washer</part>s, and <part p="4 M3">nut</part>s) attach the Y Motor Mount to the end. Set this aside for the PonokoRepRapXAxisAssembly step.
