I am having a problem with my smoothieboard not working in Y axis and will turn off the steppers for X and Z after a couple of steps. I have switched out the stepper motors with X and Y axis to make sure it wasn't a bad stepper (the steppers were switched with zero power applied to the board) and no matter which stepper motor is applied to the X axis it works (it moves in diagonal motion since it’s a corexy setup and the Y axis motor is not working). But even with the X and Z axis working, after I step them a couple times through pronterface all steppers will stop working.
Here is a little background information….
The 3d printer I built is a corexy based printer that is driven by a GT2 belt. The Z axis uses 2 steppers to which are currently jumped together. Previous to this problem my 3d printer was running great, I had full axis movement in each direction.
Does anyone have an idea what would cause this problem? Is there a way to check if the driver is blown?
I also forgot to add that right before this problem occurred, while printing the print shifted 45° as if the y axis was missing pulses.
