Marlin Bed Temperature Settings
From Open Source Ecology
- Time and temperature rise settings are found in Configuration_adv.h - if a rise of a certain temperature is not observed in Marlin - printer shuts down: [1]
- But what about the opposite - if the temperature rises too fast?
- basics in configuration.h - [2]. Set duty cycle.
Fast Heater Design
- This forum post indicates that SSRs are fine in bang-bang or PWM switching. Switching frequency should be under 10Hz. [3]
- Switching time of AC SSR is 8 ms, so Max switching frequency would be 120 hz for AC relay. [4]
- Default bed and extruder heater frequency is 7 Hz [5]
