Hi there I got question about connection of vfd to Mesa 7i96 and configure it . I got Lg ic5 vfd , on other boards (windows one) I have been using 0-10v and relay. So how I can setup it in Linux cnc plus Mesa 7i96e. I know that there been many of topics but all of them saying something different . Main question is do I have to supply 10v to board first and then Mesa is setting it up between 0-10v and what shall I put to hal file I tried to set-up it by stepconf and when program start there is some error about spindle, when I comment everything about sipndle it starts, all steppers, homes ,limits works just spindle-vfd not . Thanks for all advices . P

you can use this to a simple Filter to get to your 0-10V on the 7i96 1USD see PDF
