    Hi,

    just redrawn schematic and PCB on Eagle.

    I added 5v from motor supply, and the layout is made for rack mount.

    Naturally TIP112 must be mounted behind PCB on alu plate.

    I hope can be useful

    So is this a servo driver or a stepping motor driver? granted I have not gone threw all of the posted pages but still I'm wondering? Last I knew lini stepper was an opensource stepping motor driver

    berin, you are absolutely correct. The Linistepper is a stepper driver, not a servo driver. This thread apparently took a turn... LOL.

    Hi,
    Lini8 charge-pump modification appears to work only for Linistepper Version 1, with Enabled is High. In Linistepper Version 2, however, Enabled is active low. Any suggestions on how to make Lini8 modifications work with Linistepper Version 2? Best regards.

    Some components are mising in your component list (IC4, IC5, R11A, R12A, R46, R50-R52). Can you post full component list? Also I found discrepancy between schematic and pcb. In schematic resistor R51 attached to pin 4 of IC5, on pcb to pin 3. Can you check which is right?
    Regards,

    Hi Romas,
    Sorry,
    Component list attched.
    R51 an IC5's photo diode are in series, there is no difference R51 position. The differences may occur during PCB drawing.
