have the power transistors STP55NF06 that have VGS (TH) 2-4V and therefore do not fully open when operating 5V and with larger current sampling, such as direct switching of 3D printer heating, excessive transistor heating and without efficient cooling It will overheat and subsequent destruction!
Specifications:
designed for Cartesian coordinate system
can be expanded with various accessories for temperature measurement.
Input voltage 12V
NOTE:
