How to control the Cooling Block temperature with a pwm driven pump via PID (or bang-bang)?
Water cooling can be that strong that you want to reduce the cooling power for the hotend.
I have a Thermistor in the cold part of the hotend and like to PID-control the temperature of the cold end, which is water cooled.
How can I tell the temperature_control module not to heat but to cool?
Or is there another solution?
