5mΩ is absolutely normal for a 15A ATC fuse. A fuse is by its nature a resistor.

They are very different types of connection. You can probably get die sets which would allow one handle to be used, but this is usually the more expensive option.

@Danal said in CAN-FD cable:

Preferred cables will be marketed with terms like "High Speed" or "ADSL" or both. This indicates a shielded cable. I used these: https://www.amazon.com/gp/product/B011SS7LYU/

Which is very visibly not at all a shielded cable. There is no point in it being - the connector has no shield, the system it is intended for use in has no shield... If a foil is presented inside there unterminated, it's at best useless, probably harmful..

Cabling required should be nothing more than a common two pair cable and 6P4C connectors.

@TeddyFluffkins said in Fried 6R8 inductor and Z1284PI - why? Wiring problems:

I switched one of the two endstops to blk GND and red 5V

You placed a dead short across the 5V rail.

@doctrucker That would be the aforementioned expensive electronic fuse - a MOSFET with rough current sensing.

There are plenty of cheap ones on the market but stretching to 30V substantially reduces options, especially if sourcing from small scale distributors.
