Hi. I have verified that and the return Open on both on the axis. Could this be a motor wiring issue? I have been running my printer for some weeks with A4988 and LV8729 without any problems. Also found on watterrot that the motherboard shouldn't be powered by usb alone without the PSU, and doing that could damage the IC. I'm worried that is my case, I didn't connect it to the PSU when setting up the marlin. That is a shame if that is. :(
