New printer motor problems

[PyramidHead76]

I've just unboxed my brand new Elegoo Mars printer, but there's no movement on the Z axis, just motor noise. If I give it a helping hand it'll move, but as soon as I stop pushing it sticks again. It's not going to deal with the force of an actual print, if it can't lift the empty build plate.

Is this likely to be fixable, or do I really have to send the whole lot back to Amazon?



Thanks,
Neil.
