    I`m interested in the electrics you are going to need.
    And generally how it will work with servos.
    Look good though - don`t they. :thumbsup:
    The best I could do would be by one each month! :(
    They look like a good established company.
    I reckon Hytech will be watching closely too! :D

    Their "Clearpath SD" motors would be the obvious choice for CNC applications, since they would interface directly to the normal step & direction signals that stepper drivers use. They recommend a 75VDC linear unregulated power supply, but claim they are operational at only 24VDC.
    Their claim to be able to handle 150:1 inertia mismatch is most impressive, if real... probably not applicable to belt drive systems.
    And then there's this: "Teknic products are only available to volume OEM clients."

    The drivers are included on the Clearpath models.

    Brush less = no internal arcing . much quieter operation with higher efficiency .

    Superior in design and performance .

    In a word > quality .

    Has anyone figured out how to wire a clearpath sd to arduino using grbl. I assume you have to redo the config.h to allow for the differences in the wires and pin callouts. I am finishing up changing from steppers to servos but have not found any info on wiring except for a tutorial from Teknik that doesn't really apply to cnc gcode on an arduino.

    You only need 3 wires from arduino to each clearpath, ground, step, direction.
    Optionally you can also wire in the 'stepper enable' pin. Note that if you disable the drivers the motors will move freely and you will have to HOME after re-enabling.

    What controller are you going to use? I would be interested in how to wire it up etc.
