Сброс температуры I3 MEGA S

Здравствуйте. Товарищи, помогите) Есть принтер MEGA S, перед печатью изначально выходит на рабочую температуру. Начинается печать и во время печати первого слоя начинает скидывать градусы. До этого печатал температурную башню. Но после появления проблемы перенакатывал Cura, перепрошивал принтер на сток. Ничего не помогло. начинает на 230, опускается далеко за 200.

Начальный g код

Я только недавно начал заниматься 3д печатью и пока никак не могу понять в чем проблема
