I purchased a Routakit SD cnc machine kit about 6 months ago and I am VERY disapointed with it. I have found it impossible to "tram" the gantry and 2.2kw spindle. It is the 1500x1000. My question is, can anyone recommend a ball screw frame and Z axis gantry or something that I can swap a lot of my parts to (spindle, stepper motors etc.)? I do a lot of wood 3D and signs and just want a consistent, accurate machine.
