// S1 2014 retrofit improvements checklist
//
//replace the wiring for motion
//brace the arms for tramming - allow controlled hoz and ver alignment over +/-4mm
//replace the build platform insert with a 3 point mounter version
//upgrade the gantry to reduce vibration
//replace the platform with 3 point system for easy adjustment
//drill out a set of mounting holes on the back
//fasten the vertical rods at the back of the machine
//reduce dust, debris and thermal interferance
