    I have seen a couple of posts regarding the KL23H286-20-8B steppers, but none that answer all of my questions.

    current setup:
    – TinyG
    – Motor 1 = Z axis
    – Motor 2 = X axis
    – Motor 3 = Y axis
    – Motor 2 – Y axis
    – all 4 motors = KL23H276-28-4B (280 oz-in.)
    – 24V, 15A power supply (specifically, this one)
    24V Power Supply – Ebay

    Everything is working pretty well, but I would like more torque (I have had a couple of occasions where the motors will slip/stall. I have altered the configuration to eliminate these issues.

    I would like to move to the KL23H286-20-8B, and have purchased one to give it a try. I have tried both bipolar series and bipolar parallel, but the motor stalls/slips with either configuration.

    My questions:
    1 – What is recommended wiring configuration for the KL23H286-20-8B motors (i.e. bipolar series or bipolar parallel)?
    2 – Approx pot. setting for this motor based on recommended wiring?
    3 – Recommended TinyG settings for this configuration?

    I know others have used this motor with TinyG and have had good success. It seems like I must be missing something – I’m just not sure what at this point.

    Have you seen this:

    Parameters: It is much easier to spot configuration issues when parameters are reported in mm, not inch. Also highly recommended that parameters be entered and managed in mm mode, not inch. TinyG is native mm, all inch infor gets converted.
    Also, please put your configs in a cloud drive folder and post a URL, much easier to compare from there to a “known-working” parameter set.

    How did you initially enter parameters? CoolTerm, Chilipeppr, ?

    What is can quickly see is a 3 axis screw machine ($_tr=0.1 in).

    Are you sure that the screws are not binding along route of travel?

    Add URLs to your motor specs as well for easier location. I am not familiar with those specific motors. We seldom have to discuss motor specifics, they just work(when wired correctly).
