[ML-General] Weird Smell from Wanhao Duplicator i3 Control Box

[Ryan Coons]

Do have a recommendation for a MOFSET card? I was told to get either this
one:

https://www.amazon.com/BIQU-Power-Module-Expansion-Printer/product-reviews/B01HEQVQAK/ref=cm_cr_dp_d_hist_4?ie=UTF8&filterByStar=four_star&reviewerType=all_reviews#reviews-filter-bar

or this one:

https://www.amazon.com/dp/B01HCVJ3K2/ref=cm_sw_r_cp_ep_dp_PI.Cyb7TB37GQ

Both have mixed reviews, either working like a champ for all-time, or
broken out of the box, or catastrophically failing and danger-heating
within a month. What do?

Cheers,
Ryan Coons
