OK, i'm brand new to machining. I purchased this mill as a learner. I'v been dealing with different issues that i'm assuming all beginners experience. I upgraded to the belt conversion kit right away. Now that I've actually been using this mill, i'm dealing with some backlash issues, and the head walking downward while I'm milling. So I just bought the spring conversion kit, or should I say I just ordered it. Now I'm looking at the upgraded anti backlash nuts. The question I have is, should I continue to put money into this cheap mill or buy a better quality mill and convert this one to CNC? I will have as much in this cheap thing as I would to just buy a better quality. What say you?
