How did you conclude it was tower B's stepper that was at fault?

@dibs I just put my hand to try to stop the slider.

# Delta printer misalignment at first few layers

(Asked by: username_0 on 2018-01-16)

At first few layers, each layer has offset to -X/-Y direction base on previous layer. But above ~2mm, it is vertical.

I've checked the printer build that there is no noticeable error in towers. Tried both manual calibration and Marlin auto calibration `G33` with z probe.

No idea what's the cause and don't know which part I need to check with.
