    Hi Guys

    My Y drive has gone weird on me i can move it backwards and forwards manually but when i home y does not move forwards, it moves a couple mm and thats it X homes fine..

    Any ideas ? was printing fine finished a print then when i went to start next one it would not home..

    Restored defaults flashed firmware but no joy...

    Hmmm there are several possible reasons:
    1. ref voltage
    2. bad motor
    3. bad driver
    1. I think is unrealistic because you printed and didn't change the ref voltage.
    2. never happened to me so far, the motor are quite robust so I tend to 3.

    Do you have spares? If not just power down the box then remove the Y driver and try out the X driver just to see if it work with that one...

    Hi Alex

    i plugged the Y cable into the X and then the Y worked so stepper and cables all ok, so i have plugged a new driver in that's when i could only get it to move manually and not in auto so yes it blew a driver at the end of a print, how ironic.

    Now you mention ref voltage, i did not adjust or check it, completely slipped my mind in my desperate hast to get it working last night...

    If the ref voltage is incorrect would i be able to drive it manually but in auto it would fail ? can't check until it get home from work now....

    Torque for a stepper falls as speed increases, so if your manual drive is slower than than auto, it's possible..

    As @pSimon said yes, that could happen...

    Problem solved, how unlucky can i get from finishing one print then going to the next the drive fails, so replaced and all moved in manual, but not auto, only to discover that the end stop had failed replaced that and now back in businesses. trying to fix 2 faults at once a bit of a nightmare....
