And, although compared to the MESA board, these are really cheap, as Gene and Andy have stated this too doesn't have optical isolation. So it works fine with my Bergerda AC Servo but won't with the mini-mill without first optically isolating the PWM input and using an isolated 15V power supply. https://www.aliexpress.com/item/33021792064.html By the time you've done that the MESA is probably a better deal. > http://store.mesanet.com/index.php?route=product/product&product_id=205&search=SPIN John _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
