Y axis assembly
Ormerod Y axis assembly
Y-idler-end and Y-motor-end sub-assemblies
The Ormerod Y axis assembly instructions at Reprappro are to use interference fit when assembing the machined smooth rods and the lasercut polycarbonate y-axis-end-plates.
These fractured during assembly and it may be wise to decide on a preparation process that includes opening up the holes to a specified size or by changing the design to use printed clamps.
