Yeah, Aliexpress, and it's the JennyPrinter4. The y stop works, sort of, but the z and x does not. I've tried testing them manually, and nothing happens. Makes homing a bit tricky... :) I'm still awaiting respons from the seller on this as well, but it has been a lot of issues with the printer and the purchase in total that has made me open a dispute. I doubt anything will come of it, but have to try.
