Hi!
I would like to make linistepper but can't find PCB
I found only layer without tracks ( http://www.piclist.com/images/member...-Q33/board.jpg)

Kits for sale and PCB alone at http://www.piclist.com/techref/io/st...step/index.htm

$35.00 for 3 boards.

Good luck.

I know that, but I want to make pcb at home, is that possible?

If you search for Linistepper in this forum, you will find several threads that talk about making the PCB. Here is a thread I found that has a PCB image. You may want to contact the folks who are going this. I believe they are using Eagle for the layout.

Scroll down the page and look for Posix. It looks like board files are posted.

Hi!
I saw that, and first, I wanted to build that, but I think that it is problem to put this board on heatsink. Then I started drawing my own single layer board, but I didn't make it... I will try to make my borad; but if i fail, I will make this one.
One question: If I put my power transistor on heatsink, and connect them to borad by wire, would I make a mistake?

Good luck.

Thank you!

I don't understand how the board that Posix designed would be hard to get a heatsink attached to it? Heatsinks from salvaged PC powersupplies or a good size strip of aluminum bar or angle would work well. Put one or many 12v fans on the case holding the cards and the cards should stay cool.

I use a HobbyCNC board with old XT powersupply heatsinks and a 12v fan. These run cool.

Because I will use one big heatsink, and then I must put whole board on heatsink, if you understand what I mean, I can't put L profil on 4 transistors like on original linistepper, because 2 transistors are on one side, and 2 on the other sinde of board.
And I am not sure if heatsinks from PC power suply would work fine...
