what do you think about this combination ... drivers http://www.pminmo.com/l297-8/l297-8.htm interface http://pminmo.com/3axisopto/3axisopto.htm or is the better to go for those drivers and interface pminmo has in his shop L297-8 board and 4 axis interface ? http://pminmo.com/forsale/blankpcbs.htm i don't need 4axis on current machine, so it's not a problem.  |

| One is arranged for the DIY'er to make via toner transfer, the other takes advantage of the fine trace capability that at commercial pcb house can do.
