Hello All, I am new, real new to the cnc world. I want to convert a small bench top mill into a cnc machine. I have wanted to do this for a long time and about a week or two ago, I found the linuxCNC.org web site. I have not at this time found a computer I want to use and am looking for one.
I have wanted to do this project for a long time. Because of that, Years ago, I found 3 rather husky stepper motors that I thought would be usable and bought them. They have been sitting on a shelf for a long time. I looked at stepper drivers the other day and thought they were rather expensive. A 3 axis unit was just over $300. That seems like a lot of money to me. It is my understanding that the printer port of the computer has 2 lines per axis. One line tells direction and the other says to take a step now. That seems pretty elementary to me. It should use a small micro controller, and 4 transistors for each axis. I had planed to belt drive the lead screws with a timing belt and use a stepper motor that has 200 steps per revolution. This will give resolution of about .0005 inch per step. I may half step, but I see no reason to micro step. Am I missing something? Is there more here than I think? Is my concept of the data on the printer port wrong? Any light on the situation would be helpful Thanks bill Mark Wendt (Contractor) wrote: > Wondered if anyone has or is using the Keling KL-4030 stepper drives > with EMC2.
