Re: Brownout reset general cause?
When you measure the resistance between 5v and gnd, on a place where is an IC, basically the ic may see a sort of supply and some parts of the ic can get more or less activated. So the results are...

At least one of the above mentioned pins on every driver has resistance of 50k ohm or higher, only few of them have a "normal" rage of 40-100 ohm. I would need to order new steppers for a possible new...

Those pins are logic input pins, so they consume in miliamps range. If the resistance is high, they consume almost nothing, and that is how it should be. The MS pins have pulldowns like 100k. So the...

Pin measuring is not really an method of getting good conclusion, just sometimes perhaps could point to a problem if its an evident short or something like that. You could try taking the driver which...

Check if your EEprom is enabled and if yes, be sure that speeds are not set to unrealistic values here. It can be a problem to switch from Repetier to Marlin or viceversa. I am running motors and 2...

I've used both Mega/Minitronics. They're both well built. Megatronics is better for easy fixing if a driver burns, as previously stated. I would highly recommend getting extra fuse(s) with the board....

IF your motor has an intermittent short, this could be tripping the driver. Note: If you do not cool the driver chips (eg: heatsink and/or fan), they will overheat if they're driving stepper motors...
