Hello,

As the title says, I just noticed that the connector for the print bed on the back of the controller is VERY hot at the end of a print. I know it draws a lot of current, but is this to be expected? Prefer not to start fires, as a general rule.

This is a TAZ 5, by the way.

Thanks!

The connector used on the taz 4 and 5 isn’t rated for the full possible amperage. There are retrofit suggestions in the forum here that have been tested to work, the thread is here [https://forum.lulzbot.com/t/taz-5-heated-build-plate-connector-very-hot-and-smells-like-magic-smoke/4474/16](https://forum.lulzbot.com/t/taz-5-heated-build-plate-connector-very-hot-and-smells-like-magic-smoke/4474/16)

Alternatively you can eliminate the fitting and run wire directly.

Thanks as always! I ordered one of those metal connectors, and am probably going to just run the wire directly in the mean time. Thanks again!
