    Hi there, quick question, I have 4 Pibot toshiba tb6600 motor drivers powering my ox cnc motors, 3 of which, when I power up, both the work and power lights come on solid with no signal from breakout board and one that only the power light comes on. The 3 that come on are for the 2 x y motors and the x motor. The one that doesn't come on is the z driver. All connections to motors and breakout board have been made. Lights the same with breakout board powered or un powered however work leds do respond correctly when pulses are received from bb. Any ideas?

    All drivers respond correctly and work as should.. Rather bazaar, can't seem to find anything in the manual about the led function.


    Thanks for reading

    I'm a few years late to reply but this is likely due to a short between stepper motor wires
