The automatic operation of the blowing fan causes that the hot end cannot be heated

For help, I click to start printing. After returning, the hot bed starts to heat up, and then when the hot end starts to heat up, the blowing fan will automatically start, causing the hot end to fail to heat up. We didn't encounter this problem when we didn't use ratOS. Today, we tried to install ratOS. What needs to be changed to prevent 5015 from running automatically when there is no printing

so you enter a temp in mainsail and then both are on?# jsut want to make sure we are on the same side you say you have a dual 5015? did you spliced the wires or do you use two connectors? you must have messed up it somewhere i would disconnect one fan to see if ti works and then test the other fan that behaviour is not right

Manually set the temperature rise 5015 will not operate, and the temperature can rise normally Splice the wires and merge two 5015

Each time you click to start printing the part, and then the hot bed is warmed up

What is the maximum temperature of the hot bed in ratos? Is it the maximum temperature problem

That's strange. The temperature does not exceed the maximum value Surprisingly, they engaged themselves and did not move anything
