Qidi Tech 1 - Replicator 1 clone

Check for loose connections on the bed and on the main board. Look for any pinched wires.

You might swap the two extruder's heater and temperature sensor plug connections at the motherboard and see if the problem followed those. If the problem follows the swapped components, then the issue is most likely associated with those swapped components. As physical temperature involves significant thermal inertia, the issue is most probably with the temperature sensor. Bad connections / a failed temperature sensor are probable. Replacement parts are available from QiDi and there are videos on you tube (search for "qidi tech") showing how to perform the replacement. If your QiDi is still under waranty, contact QiDi for the parts. Sometimes they will ship via DHL which will cut several weeks off the delivery.
