    I bumped PWMmax up 1step at a time all the way up to 255 and motor never moved

    Is it just this one motor, do the others work OK?

    I can't see the detail well on the video, is the motor exceeding the limits when it starts to move, that will cause a shutdown for safety reasons?

    I replaced arduino, thanks for hanging in there with me. If you don’t mine can you help me with the other setting when you get time

    The rest of the SMC3 settings depend a bit on the specific hardware and rig design, but are detailed here: https://www.xsimulator.net/communit...driver-and-windows-utilities.4957/#post-48121

    While written with a different control board and software in mind, the basics of this simplified introduction to PID are the same, and there are also links to more accurate but technical PID information, depending on how far down the rabbit hole you want to go: https://www.xsimulator.net/community/faq/a-laymans-analogy-guide-to-pids-pid-tuning.219/

    Hey guys I’m gonna definitely need some help tuning, my #2 motor swing done and hit the table and hitting the clip shutting down the motor. How do I limit how far the arm swing?

    The Clip Input and Max Limits define the range and also the reverse breaking band between them: https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/

    Clip Input Used to create a band at either limit of the target range beyond which any values sent to the SMC3 are clipped. In addition to this clipping, if the motor feedback does move beyond this range (typically through inertia), the SMC3 will attempt to brake the motors hard by driving them in reverse until they are back out of this limit zone. The value can be anything from 0-255 (however can’t be less than the current limit setting). Reverse braking is applied in the band between the Clip Input and the Max Limit settings. Reverse braking can be disabled - refer to PWMrev.

    Max Limits Used to create a band at either limit of the feedback range beyond which if the motors move (typically through inertia) the SMC3 will automatically shutdown the drivers and keep them disabled until reset. This is essentially a safety mechanism if something goes wrong. The value can be between 0-255 (however can’t be greater than the current clip setting).
