This is a case for the kind of crappy TB6600 stepper driver controller. Like the one sold here: http://www.ebay.com/itm/CNC-Single-Axis-TB6600-0-2-5A-Two-Phase-Hybrid-Stepper-Motor-Driver-Controlle-F5-/291714731792?hash=item43eb8d8f10:g:e6oAAOSwxvxW70iX

These drivers can be greatly improved by my posts on this cnc forum.

These improvements include the requirement of a fan (in this case a 40mm fan). Any fan should work for this case and 40mm fans in many voltages are available from aliexpress.com and should be able to be run directly from your stepper driver input voltage.

Fan mounts on outside of the case using some #4 machine screws and nuts (I used 11/16 long screws but that will depend on your fan thickness).

Can probably get away with much lower infill. Some bridging errors can be expected if you have bridging difficulties. Rafts are needed for ABS to prevent warping of the corners.

Hi there! I have the same www.hyu68.com HY-TB268-N6 that you do. Do you have a picture of your boards with the resistor wired in series? Based on calculations if two are wired in series thats actually .44 ohms. Would I be replacing the two onboard blue resistors with four ceramic resistors total?
