Fan setting and control
I try to setup firmware configuration, and have problems with fans. I have a corexy printer with one extruder, RAMPS 1.4 and Repetier V 1.0.0dev.
Actually, I don't understand the definitions and settings about fans and temperature control, so please help.
I have the hotend cooling fan connected to D9 and so I can control the fan via Repetier Host manual control.
I have installed a fan extender board on the servo pins and have tested this with a small ,Arduino test program. The two servo outputs work on Digital pins 4 and 5.
What I want is:
- Hotend fan only controlled by extruder temperature (e.g. start at 100°C with low PWM setting and go to max PWM setting 255 when reaching target temperature.
- print cooling with a second fan which ideally gets manually controlled via Repetier Host. Don't know whether this fan could also be controlled by a Slic3er setting.
