TB6600 / HY-DIV268N-5A Problems, and possible solutions

[davies46]

Hi,

I'm also using TB6600 based controllers... these super-cheap ones:

and they're fine apart from after about 10 minutes any of X/Y axes will die, all indicator lights off on driver, until I power cycle it. They don't seem very warm and they don't auto-recover as you might expect if it were overheating. It's perhaps too different from your circuit but maybe someone here recognises the problem.

Over current? Totally dodgy circuit / waste of money?

Any suggestions appreciated!

(36v 15A power. driving fine using GRBLv1.1. Failed on highest power and the one down from that)
