Fans and ambient temperature
I have my Robox Dual next to my desk, and assume many others have it somewhere close to their workstation as well, and was just wondering if it's supposed to make as much noise as mine is doing now. I think the majority of the noise comes from the fan on top, that seems to run at max continuesly during all prints regardless of material or ambient temperature settings, and I'm not sure if it's always been like that or if it's changed at some point in time. I do suspect it's not always been like this since I used to be annoyed by the stepper motors and bed resonance, but now I can't even hear that because of the fan noise.
I've also noticed that for some filaments, like TitanX, the ambient temperature is set very high (60 degrees I think?), but never seem to climb above 30 or so. If the fan is running faster, or more frequently than it should, I assume these "issues" could be related?
This is the description page for the M105 command Espen refers to. https://robox.freshdesk.com/support/solutions/articles/1000138396-m105-command
Ambient temperature threshold is set using M170 command
M170 - Set ambient target temperature [S] S=Override Temperature °C . This command sets the ambient temperature using data supplied from the reel EEPROM. [S] provides a manual override for custom temperature. e.g. M104 will set the ambient temperature to the value stored on the reel / previous value sent, M170 S35 sets it to 35°C.
eg the following command entered into the GCODE window and sent to the printer
will set the system so the ambient fan will extract the build chamber to try to keep the temperature below 60°C.
The sensor is just behind the head at the bottom left on the rear of the gantry, it is visible just below the finger wheel.
