My new little baby 3977

Dang, those tssop packages are a pain! Basically it's the same circuit as the other 3977 boards just using the small package. Third times a charm, tried the solderwick method to solder the little burger the third try, and whatta you know.

That board is a precursor to this one. 3 axis, connector for a compatable 4th axis. DB25 in, switch inputs for 3 axis of home and limit switches, 2 driver output for spindle and coolant.

Phil, looks good! Where did you get the boards made?

[pminmo]

H500,
www.olimex.com

They have done several different ones for me, I've been quite happy. They will take eagle .brd files. There are some gotcha's, their standard drill rack is pretty different than eagles standard libraries, so if you don't do some work on the components you use, the price of the board goes up in a hurry. An internation fax is required for a signed PO, those aren't cheap either. But all in all, it's the most reasonable I have found.
