Duet maestro cooling in a passive heated chamber



  • I have a duet maestro driving an anycubic predator enclosed in a plywood and plexiglass triangular prism-shaped enclosure. The enclosure is close to airtight; the only significant gaps are at the bottom where the power and ethernet cables exit.
    I ran a test by just heating the bed to 100 and letting it sit there. The hotend(not-heated) reached a temperature of 45C. From this I assume that the air temperature in the chamber is about the same. Based on what i've read in this forum, 45C chamber temp is sufficient to keep ABS from warping, so can avoid adding an active chamber heater, as it seems that the bed can heat the chamber enough.

    My question is this: will 45C air temp be a problem for the duet maestro?

    That depends on what motor currents you are using. With a higher ambient temperature, the drivers will obviously get hotter at a given current setting.

    It's more usual to put the electronics outside the heated chamber.
