Maximum enclosure temperature for Duet boards?
-
My printer resides inside a semi-sealed dust proof "booth". Now that I have the ability to produce multi-material parts, a heated chamber would likely be beneficial. However, I don't have the funds to convert my machine to a full heated chamber design and in any case, that would be difficult to do with my 6 input multi-material hot end. Nor can I easily separate the electronics from the rest of the machine. So I'll have to settle for heating the entire "booth" including the electronics that are inside it. I appreciate that this will limit the temperature that I can heat it to. The question is, what is that maximum safe temperature? 40 deg C? 50 deg C?

This is the answer I got when I asked.. for what it's worth, my old 8bit Rambo ran with no problems in 50C enclosure so I have no worries with the Duet considering I have a 24 and 5v fan in the board box.

I seem to recall the last time it was brought up for tool boards is was around 80c. But that may very a bit depending on which boards you've got in there and the individual components on the board may have different ratings.

@airscapes Thanks - I tried doing search before I posed the question but obviously didn't use the necessary key words.

Wow - that's a lot warmer than I thought would be possible. But I guess I need to be more specific. So the question now becomes, what is the maximum safe continuous temperature that I can use with one 6HC main board and three 3HC expansion boards? The boards themselves are not enclosed. The 6HC main board has a cooling fan blowing air onto the underside but the three 3HC expansion boards do not.
