Y axis motors are out of Sync



  • Hi,
    I am using the Duet WiFi and the Duex5
    I am building a 3d printer and i have two y axises on it and i have one the y axis driver and one on the other on the E1 Driver. At first they weren't moving in sync and we didn't know why. we originally thought it was the motor so we switched it out for one we knew was good and it still did it. the one that wasent moving enough was on the E1 driver so we thought it might be that even though i did the M584 command to map it as the y axis. so what we did was switch the wiring the one one the E1 driver now moves the right amount but the one on the Y axis doesnt.
    If anyone has any idea of what going on it would be a great help. and it you have any questions just ask.
    Thanks

    You need to post your config and homing files so we can have a look.



  • Is this on 1.21 or 1.20?
