 The changes shown here require knowledge in the field of Arduino IDE, Marlin and electrical engineering and can overwhelm normal users. Also, I would like to point out possible dangers that exist in certain interventions. All adjustments have been checked for function.

-**What is this about?** \\
+**Why someone would do this** \\
-The TMC2208 is a German development. This tutorial is about making the A5 quieter. It is not my intention to explain all possible options of the TMC2208. Like me, most users will buy these stepper drivers just for one reason: to have silence. I focus on installing and configuring these drivers.\\
+Silent motors, sensor-less homing and higher voltage than the TMC2208s.
-Why use only two TMC2208?\\
-The most noise comes from the Y-axis and the X-axis. Because the Z-axis rarely moves when printing you do not hear much noise. The TMC2208 can deliver less power than the standard A4988 driver. One Z-axis driver needs to power two motors at the same time. The avaliable motor current is divided between both motors. \\
-You rarely hear the extruder motor. If you hear it, then at the retract. The extruder motor, however, requires a lot of torque to press the filament through the nozzle. Much torque means a lot of electric current. This is exactly what the TMC2208 __can not do__. \\
-For these reasons I used the TMC2208 only for the X and Y axes. \\
-The TMC2208 stepper driver includes the function of TL-Smoothers. So it does not make sense to install this extension when using the TMC2208.\\
--> I have written a separate article on how to reduce the noise of the extruder motor. \\

 Note:
-If you opt for this optimization, then always do both the hardware,
+If you want to do this mod, you MUST do both the software changes and the hardware changes.
-as well as the software conversion.
+I HIGHLY recommend the SPI mode and that you purchase the V1.1 instead of the V1.0 for the basic fact of a few extra dollars and much less work.

 **Please first pull the A5 mains plug**\\
-Before you install the TMC2208 module into the MKS GEN_L motherboard you should remove the pin named "NC" for safety reasons. "NC" means "Not Connected". I do not know if this contact is connected to the driver board. I have removed this "NC" pin therefore. So one experiences no unpleasant surprises.\\
+Before you install the TMC2130 module into the MKS GEN_L motherboard you should create your cables as per the wiring diagram below and confirm that your drivers have the SPI and other settings correct. I am unsure where exactly the Z and extruder CS pin should go as I didn't have the extra drivers for those axis and DaiHai's wiring diagram on his video was incorrect as I would get readings from the drivers that would be FF:FF:FF:FF meaning that the pin wasn't seeing any data come back from the driver. I got this wiring by trial and error testing. If you don't have the printer erroring on you trying to connect to it then you have the correct pins. If you are trying to get the Z and extruder to be on TMC2130s then I would suggest once you can connect to it, confirming the right pins are plugged into the right connectors by removing them and making sure the one you removed is the one erroring with an overtemp error once you try to connect to the printer again.

 When inserting the modules into the sockets, it must be noted that the mounting direction is different as with the A4988 driver (see photos).

 IMPORTANT POINTS:
   * When measuring Vref on the TMC2130, you need to measure the voltage from the Vref hole on the V1.0 and the poteniometer on the V1.1, (see photo) to ground.
