I know for heatsink, but it is designed for 25 A, i tought that this 8-9 A will be nothing fot it.
It is connected now with mechanical relay....
But i have another Q - in Marlin, is there any code that for controling when it start heating and stop heating .
If set let say temp= 100 oC
why not heat to 102, then turn off relay- till it reach 98 oC and then again turn on relay.
Insted of - when reach 100,xy it shout down relay, and on 99,9 it turn on again ...
many clicks for controlling temp it is not neccesery to be exact 100oC...
