trying to figure out what's happening and was wondering where I should start. I currently have the E3D v6 and my printer all of a sudden stop printing about 4 hours into the print. The extruder actually stopped on the print. At first I thought The might of been a power outage but not the case. I removed the part and tried to reprint again. The printer started the level check and then froze? I went into simplify 3D and check the temps and noticed the bed temp goes up but the extruders not budging. I checked for loose wires and don't see anything. The small fan is working fine. Where should I start troubleshooting?
