Orca 0.43 X-axis HGR15 and HGH15CA linear carriage and raceway upgrade

This is an upgrade to the Orca 0.43 x-axis.

I bought a raceway 360mm long, anything up to 373/374mm long should fit fine. If in the UK, http://www.marchantdice.com are great, and extremely local to me. They'll cut it to the length you specify, just make sure to email them for a quote/paypal payment, as their website doesn't have selectable prices for lengths.

As the raceway is completely rigid and straight, it stops any bowing of the axis due to tension between the original two rails, whi
