On built in vs modular socket, we have determined that with correct installation and heat management the built in option offers superior life to little modular driver boards. This is due to the sometimes overlooked fact that most motor driver chips are designed to dump their excess heat into the board through the ground conductor on the bottom of the chip. This puts heat sinks that you add to the top of the chip at an instant disadvantage and placing the chip on a small board significantly limits the area to which the heat can dissipate from the driver chip. We have chosen to stick to the design specifications for area around the chip and board features that draw the heat from the chip into the full board ground plane. As a result our drivers barely get warm and require no forced air for cooling thereby significantly extending their life expectancy.

Also, the mainboard has 2 oz copper center as opposed to .75 or 1oz on most board, this makes it run cool even for 100 hour prints.
