This covers TMC2130 and 2208

According to test results at 36V - the torque is great in Stealth Mode up to to 250mm/s - [1]

If smart controller is on Aux 3 - need to wire into Aux 2 headers - see Step 4 at [2]. Disclaimer - author questions validity of LCD working with TMC2130
Covers 3 parameters set in software - sensitity to bump stop; holding torque; conversion from 16 to 256 microsteps
Stealth chop gets you less power - how much less? Less speed. Unacceptable for fast bulk prints on large printers
Can run in hybrid mode to set Stealth mode only below a certain speed, and high speed is noisy.
Nothing about solder bridge on the driver to select mode?

Chris Riley - [3]5
Step, Dir, Enable pins face down [4], 4 pins up. Diagnostic pin goes up [5].
Sacrifices LCD for this install. SDRAMSP supports is commented out [6].
Diagnostic pin goes to the end stop signal (rightmost). So effectively, we have to solder one pin on the TMC2130 to replace the end stops. That is worthwhile.
Set x and y home bump to zero when using sensorless homing in config.h - [7]
Install the TMC2130 library via Sketch -> Include library -> Manage libraries... But which version?
Need cooling fans - [8]
For the pins that we reassign - make sure you don't steal them from EXT2 if you are using the second extruder steppers [9].

Swap motor direction by reversing 2 outer pins on either side, or reverse in Marlin Firmware. (just plug reversal in Marlin?)
If you have Marlin <1.9, that's it. But Marlin 1.9 and up, need to select the drivers that you have to TMC2208 (selection is not avilable in Marlin 1.0)

Yes! Drop-in replacement that is quiet, with Stealthchop2. [11]. Requires no firmware upgrade if using <Marlin 1.9. Question is if the torque is acceptable.
TMC2208 Instructable - [12]
Yes, can get quiet operation as drop-in replacement, no modification needed outside of small firmware change, but not sensorless homing. [13]

Marlin docs on TMC2130 - [14]
New: Marlin docs including TMC2208 - [15]
Hackaday post - summary is that it's a job to configure properly - [16]
Prusa forum - good list of references - and explanation of low torque is 12v operation instead of 24 or higher. 1A at 24V only is required to run all stepper motors??? [17]. See first response, Hardware point #9.
