I am fairly new to CNC but I have completed the build of an MDF CNC machine and got it running. I realized my Z axis is in bad shape and decided to build the CNC router parts standard Z axis. My thought was that it will help me to slowly upgrade the other two axis to aluminum in due course. I got all the parts yesterday evening minus one little part. Cory at CRP was very helpful in discussing my need and guiding me to get the correct parts. I will document the build here for the benefit of other newbies like me and to get some feedback from the experienced folks out here.
Here is what i am building
