Hello all,
I am presently designing an SX3, table top mill conversion. This project will be in the planning stage until all needed components are first fully researched. I am sure anyone on a budget will fully understand that.
Right now, I am researching axis drive motors and a new spindle drive motor. My goal is to use quality servos that don't cost an arm and a leg. I came across the company Teknic and investigated their site. I am impressed with their line of servo motors, meant to replace stepper motors and associated controllers. The price is within my budget and is comparable to a quality stepper setup.
All of the new Teknic products offer extensive documentation, and is well written for a hobbyist building a CNC conversion. Each motor has its own, built in controller, that accepts direction and step signals, as well as output for position sensing. According to documentation, these motors are intended for uses that include CNC machines. They will sell any number of product to anyone, not just OEM. This opens them to the hobby market as an affordable, quality solution. Here is a motor that I have been thinking about:
