yeah I decided to burn my walled even more and bought this https://www.amazon.ca/gp/product/B01...?ie=UTF8&psc=1 stainless steel, will be arriving tomorrow. but gonna hafta wait. hopefully I can get the carriages all installed by tomorrow, and then the wiring on Monday (thanksgiving in Canada). Yeah I think it's a layer shift, and the fact it happened on a different height after reformat sd card and cube is okay, I think it's the sd card. Again will know later today if Amazon even ships it! (says it's arriving today by 9pm but hasn't even been shipped yet :P)
