Just wanted to throw in my 2 cents: Probably the best upgrade to a stock Chiron printer. Removed 4 screws on the bottom, popped the old ones out, put these in. I opted to change the order of the wires rather than mess with the firmware, then it was a simple matter of checking the voltages with a multimeter (I just stuck with about 1.15 and its going ok). It's all unbelievably silent now, and my first test print came out looking great.
