Hello, i am new on this forum and i also build this interface and driver.
I put the schematic that i use. It is inspired by http://www.cnc-dag50.it/content/view/23/42/.
I prefer to work witout PIC because i think that L297 have all to work well.
About breakout board i do with the same Ic hcpl2630 but i don't undestand why you use after 2630 another Ic.
I put also my schematic and pcb made in DIP Trace(it is free version).
I want to make an image and reconfigure my cnc driver.
Thak you
