| OUT1/2/3 up to 6A each

This is the recommended current, but in the data sheet the max mosfet current is 9.6A, other data, the previus version mosfet is 50A.

with 50A mosfet the 15A fuse will work and avoid overload.

May be it is necessary to read well specifications after new version but the components after fuse must to be dimensioned to enduring until fuse work.

OK, you can not protect the duet against any risk but The problem is that there is a fused to protect circuits under VFUSED, a good desing muts to keep this in account.

Of course after this incident we will put fuse in not protected lines.

our duet 6hc has burned after a shot circuit in OUT3. In previous versions the circuit had a 50A mosfet but in v1.02 the mosfet maximun current is 9.6A.

The mosfet has a cooper dispator and can enduring more current than 9.6A but in this case was not enough and the mosfet becomes burn before the 15A fuse works.

For me this is a desing fail, the circuit must to be protectec and designed againts any overload.

WE have a problem with 5V duet line, our 3DTouch autocal do not work well, we need to put a condensator to filter else the autocal do not work.

I do not have oscilloscope and i do not know if the problem is noise or electric curling.

the mount is: duet, 12V power source and autocal.

duet 6HC V1.02

We do not have this prblem with previous versions.
