The drivers are from Gecko. They are all model G210. The G210 model allows several different microstepping modes. I use three motors for single stepping and one set at 10 microsteps per step out of convenience since I have one project that requires microstepping (the Egg Mill) and most others do not.
The power supply components were purchased from Camtronics Inc and include two transformers hooked in series, a bridge rectifier, and a giant 18000 microfarad capacitor. A bleed resistor is installed across the capacitor terminals to safely bleed off the enormous charge that gets built up in the capacitor.
Each stepper driver gets a dedicated 5 A slow blow fuse.
The fan pulls air through the large heat sink that the Gecko drives are attached to rather than pushing it through to cut down on inefficient swirl
