Demonstration of a Flashforge Dreamer with TMC2208 based driver boards installed on the X and Y axis. The stepper motor driver cooling fan (on the control board) has been replaced with a rubber mounted Noctua fan to reduce overall noise.
EDIT (09-23-2019):
I did not need to make any changes to the firmware or Flashprint to use this modification. My driver board was not plug and play because most TMC2208 drivers have the pins soldered on the side opposite of the drivers on the Flashforge Dreamer. I removed all the pins and installed new ones on the correct side. An easier method would be to purchase boards without preinstalled pins, then install them on the correct side yourself. Finally, the polarity of the stepper motors with upgraded drivers need to be reversed to compensate for the reversed polarity on the TMC drivers.
The Z axis driver can be changed as well, but I would recommend switching the drivers to Spreadcycle mode for the increased torque needed to move the platform. There are additionally two drivers for the extruder motors, but I did not see the need to change them since they produce no perceivable noise and would not benefit from microstepping. All things considered, two drivers (X and Y axis) appear to be sufficient to gain the maximum benefit from this upgrade.
Summary:
1. Plug and play in terms of software/firmware
2. Not plug and play in terms of hardware
(a) orient driver pins correctly
(b) correct polarity on stepper motors
