So it is about time I start a project log. This one is going to take some time (as I don't have any time or the $$ needed). What I am doing is taking my X2 that has been converted to CNC (X and Y only) and giving it an overhaul. The mill was originally converted using FigNoggle's CNC Plans. I wasn't happy with how the Z was in plans, so I had never finished the conversion. As it was, the mill got heavily used (for those not familiar, I was making and selling some bike bits). I also never did anything about the leadscrews. Stock they are*yoda voice*. Same with the nuts. I have just adjusted it out the best I could and used backlash comp in Mach3. Accuracy has been going down hill for some time now. It is at the point of being, unacceptable. The plans? 1. Replace the stock lead screws with some precision acme screws and acytal nuts. I already have the materials from another project that never happened. This way I don't waste anything... Going to have to extend the X screw to work with the design in my head... 2. Use the base from LMS high torque mill that has the longer Y axis. I can't afford the whole BASE & Table, but I should be able to get some benefits from the base alone. 3. Re-design the motor mounts from what I have now. I will go into more detail about that as I plod along. 4. Re cut the 55* dovetails to 60*. I have read on CNCzone about some people that have done this. Apparently it allows for a thicker brass gib. I am still up in the air if I am going to do this. 5. Design an actual Z axis that I am happy with. I have a spare column. I have the gas strut conversion kit. I also have the longer rack. I have ideas, but nothing concrete yet. I started working on this last night. I will straighten out my picture hosting and then start posting what I am doing. **I know some people will ask, why not just start with an X3 or a G0704. Well, I just don't have the cash and may not have the room for one soon. Got to keep my hands busy... |

Interested in how you are going to CNC the head. The fignoggle plans and the steele plans always look crude to me John s. |

Minor tool gloat... Picked one these up from ebay. Was going to build Bog's version, but at the price of this one, $49 usd, I decided not too. |
