    Why'd you get the P, O, S, TB6600?.

    Hope you didn't pay too much.

    Should've saved yourself aggro and just gone with 542 or 556.
    You get what you pay for.

    As I've said numerous times before, TB6600 are OK drivers, yet you seem to want to say they're rubbish at every opportunity.
    They are by no means a high performance driver, but they're a reasonable basic stepper driver.

    It was the older TB6560 which was well known for failing, but that was mostly down to people trying to run them on too high a voltage. If you actually ran them within their operating voltage range, they were an OK driver.

    Not every application needs maximum voltage or performance.

    Hi Thanks again for your help. I now have power to stepper motors but they will not run, they sound stalled or trying to run to fast so do not rotate
    Do you have any idea ??

    Double check you have A+A-B+B- motor connections in the correct order on the driver. If incorrect you can get this happen due to dir conflict.

    Which model numbers are the motors specifically.?.
    What is actual machine?.

    Hi It is a home built and was working great until my Geko 540 gave up. Do I use all six wires fro the motor and Bipolar series??

    Ah!!!!.
    I see 8 wires.
    Best balance for both speed/torque is parallel. Also lowers your inductance. Twist pairs together and connect as folliws:

    A+ RED & BLU
    A- YEL & BLK
    B+. WHT & BRN
    B- ORG & GRN

    Then 10-45v power supply in the other 2 terminals (marked 32v & GND I think).
    Try that.


    I see your motors are 3.2mh inductance in parallel (it's lowest level avail). Not great for trying to get fast rapids on only 36v or less. Fine for general cutting speeds.

    Most likely happening because your motor tuning in mach3 is set for the Gecko drives and these cheaper TB-based drives cannot handle the same tuning setup. Try backing off the velocity and Acceleration by 50% and try again. When you have it working stable then slowly increase them one at a time until they start to stall again then back off again by 10%.
    -use common sense, if you lack it, there is no software to help that.
