HI Lucas,
thanks for your hint. After I studied the datasheet I am convinced. And yes they have resolved at THB6064 the mandatory sequence of power switch ON / OFF as well. That is good news.
I studied the public information provided along your kits and I feel now that any own effort is obsolete. Now I decided to spend same money I have spent before for Chineese drivers again - but into something working fine.

At your kits you have a heat sink. How warm does it get on long term and heavy duty. Is it recommended to add a blower to the heat sink?
What gauge and what length do you recommend for motor connection? Is it necessary to mount the drivers in very proximity to motors as to travel with the mill movements.
