I checked the error log and can see E12, B Axis commutation failed. I suspect B axis is not sitting straight and is falling to the side when the machine commutates. This is usually caused by the HP coil pulling the cutting head to the side. After rebooting the machine watch closely when you turn it on to check for the cutting head moving.
Poor commutation will make the motor overheat and eventually cause a longterm current overload error.
If this is the problem try to adjust the coil to keep the B axis straight.
