OTOH when I built a new box for my drive electronics, I used 1/3 & 3/16 thick alu panels & stuck a 6" rotron 120 volt noisemaker inside the mostly sealed box, then put a another much quieter fan to skim the top with shop air. At 99F in the shop, a probe stuck through an empty cable hole & inside about 3" said 107F inside the box after about 7 hours on time. That is good enough for the girls I go with. :-)
And it should stay relatively clean inside. I'll see how dirty it has gotten so far in the next day or so as I intend to check dipswitch #4 on the A axis driver, it is not powering down to 50% drive when idle, so that motor is running noticeably hotter than the other 3. If the switch is set, I'll bounce it back, as I bought an extra driver when I bought those. Precisely for that reason. :) > Jon Thanks Jon.
