Almost there..

Been a while since I've worked on the machine but it's nearly there. All the software and firmware is setup and just a few final touches to the mechanics of the machine to go. I've had it dry-running a complete job and seems to work fine. 

The heating elements for the nozzle have just arrived from the UK so I have machined a copper heating block for heating the nozzle.
