defect?

[iIiastro4KiIi]

My m3d Micro is running some grey hatchbox pla. I've noticed for a long while that it hasn't been sticking to the build platform with the plan that it came with. it stopped printing overall for a few weeks until i got the matchbox. it was not sticking to the bed for most of the prints.it has been sitting in my basement for a couple months now. i tried to use it but Now the X axis arms are going crooked about 1/2 hour into every print. Im using a Low Poly Pikachu as a test. I'm hoping i can still get a refund.

Is it a defect; or is this happening to a lot of people?

(not saying there isn't a lot of people that have m3d defects)
