I dont think having the ballscrew offset on the X axis is helping accuracy very much. Id prefer to go for a smaller ballscrew mayber 10mm or even 8mm and run it through where the original leadscrew was. Your mounts also dont look very rigid at all. You need solid couplers and I think a better option for mounts would be thicker aluminium plates supported by 4 pillars. All this could be made on the lathe fairly easily without the needs for an external supplier.
You may be right. I did put 12mm ball screw later and it got better. Yet, it is possible to put it beside, but you require a hugely more rigid connector.
Great video, very useful for my planned conversion. Do you think it is worth adding a gear reduction system for increased torque? I'm thinking about using a belt and some pulleys.
Thanks James. Everything is possible, but I have not found torque a major problem. I would love to have a lower speed and higher torque, but it is easier to focus on what we have. Making noisy gears to me a bit too much effort for little output. What I want is a good rotation speed indicator (with 1/100 turn readings) and computer-controlled speed
Полмиллиметра это как то уж очень многовато. Наверное эти тонкие нежесткие кронштейны надо выкидывать? Ну или как то их большего сечения вырезать? Или поправок после контрольной проточки и измерений на паузе после неё хватит для нормальной точности? Только тогда код надо параметрический для машининга писать-генерить.
Mach 3 to start with; then Fusion 360. And it took forever to understand how to use Fusion for G-code. Possibly, I shall make a video on this at some point...
@@is_it_science Yea, that would be awesome to see how Fusion gets gcode saved. I'm all new to this, and using UCCNC software instead of Mach3 and vcarve pro for generating gcode, Fusion 360 looks very hard.
I would love to, but I am barely able to keep up with the other interests... It is surprising, why the Chinese do not do reasonably-priced CNC lathes....
