C0 Lathe Blowing Fuses. Control board short?

[Speedy Builder5Participant @speedybuilder5]

It poses the question, Why did the diode(s) die ?

Believe me, diodes die !

Hi, It might be worth fitting a fuse in one of the motor leads,then if the motor stalls ,it will hopefully blow the fuse before damaging the controller .

No point in fitting a fuse, semiconductors blow faster than any normal fuse.

Diodes, like most semconductors fail for a number of reasons including manufacturing defects, but most common is overloads, including voltage spikes. Given it's a low cost lathe, it was probably marginal manufacture.

Moral of the story – always ask for help!

On a personal note, im really glad I "had a go" at fixing this myself. I've learnt a few things and I actually really enjoyed the process. 👍
