Sieg X3 Super - Simple CNC conversion.

Using mainly commercially available parts and a few very simple fabrications

Thanks for the link to your cnc conversion. These write ups are very useful for those of us contemplating a cnc conversion. The work involved in recording your project must have been considerable. I'm interested to know how the Leadshine drivers/motors perform. They seem much smoother and quieter than standard steppers. I also like the idea of using belt drive to the steppers. I made up a simple cnc router last year, and getting good alignment of the steppers to the feedscrews was difficult. The belt drive overcomes this, as well as allowing more flexibility in positioning the steppers. I had an Emco Compact5cnc lathe, and this used a 1 to1 belt drive for the steppers.

Hi,

I decided on using the Leadshine solution as I was worried about losing steps. This is another reason why i used toothed belts to ramp up the motor torque. They self correct trying to pull back to the known position.

I have not got any other stepper motors to compare noise ratios, but is pretty insignificant when you start milling any way. I have found that the PC selection makes some difference. My original was an older scrap dell with xp and had to be replaced. My existing system , still hesitates occasionally , but is generally ok. At some point I may buy a more powerful 64 bit pc but its not really necessary. Try having a look at the pre-made aluminum mounting brackets, they can save a huge amount of time mounting the bearings.

Best wishes Mark
