1 , each one will do functional testing.
2 , especially with a 3Pin 70cm connection for easy connection to the ramps1.4 use .
3 , the official wiki design a diode D1 ( to prevent reverse power ) ,
resulting in a pressure differential between the two sides of the ground ,
so that the thermocouple output signal Sg,
to the motherboard rear end becomes Sg + Vs,
so will lead to temperature allowed,
our version using 0 ohm resistor in place of the
diode temperature measurement more accurate.
1 , and the official version is not fully consistent ,
revised official version of the differential problem ,
with 0 ohm resistor instead of a diode D1 .
2 , due to low production , small welding difficulty , using manual welding.
Suitable for : ramps1.4 and Ultimaker , etc. can be used.
