hey all, I build a Lead 1515 with the high Z mod and have added a second Z axis for a plasma torch. I need the High Z due to the Plasma water table that sits onto of the milling surface. unfortunately this creates a fair amount of deflection and chattering during milling operations. I would like to add a second c beam to each side of the Y axis as well as a double large gantry plate assembly to add ridigety. bails I'm coping the X axis design and moving it down to the Y. MY question is if anyone has done this? is there a parts list of what is needed?
