    MPG Pendant update and issue

    Hey guys this is an update from the last post about the MPG I fought for weeks and finally got going , well for a while ....I was running the router that has the mpg on it and the driver blew out which was expected so I changed ll the tx14--- drivers it comes with to a stepper online driver same as the tb6600 drivers and all seemed to work well beside the MPG . Here is the thing I can jog no problem on every axis except for the y axis and that is the one that blew the driver before . Using the keyboard in Mach3 jogging works fine no issues in y but when I go to the MPG y will only jog in the plus direction . Has this happen to anyone else or does any one know what this could be ? Should I change the stepper motor out ?

    If the stepper works when jogging with the keyboard then the stepper should be fine. I would be looing at the MPG. Check the direction signal going into the drive to see if it goes hi and low when you change direction.

    Yes all that worked fine before having a driver burn up

    You could try swapping the X & Y motors and see if the problem follows the motor.

    So the problem went from the y to the x as I switched the wiring so this told me the motors are good ?? I don't know if I need to replace the driver and the motor because it worked when I flipped the wires . This makes me think the wiring has burnt out or the connector has a short any suggestions???

    Update.... I have tried just about everything v
    I replaced the motion controller board thinking it my have been an issue with it but I get the same results so I am stuck.!!! I can jog the machine with the keyboard in mach3 with no issue thats whats got me . When I try jogging with the mpg pendant everything works except for the +y direction. Im out of things to try other than replacing the motor and driver does anyone have anything I can try before I replace the motor and driver ?????? Just for the record I have moved the wires over to the x axis and the issue follows the wiring and when I swap the wires at the driver the problem follows
