An Overview on TMC2130 Upgrades for the MK2, MK2S and MK2.5
There is a lot of interest of non-MK3-Users in TMC2130 stepper drivers. As there are different ways to get this done,I want to compare those and to share the details I learned. Let's make this thread a helpful for everyone who is planning to upgrade. Any help is welcome. I intend to keep this updated.
Option1 - Switch to Einsy board
- You might run stock MK3 firmware and can get all the other features (lost-step-detection, switchless homing). However this also requires PINDA2 and filament sensor (MK2.5 upgrade)
Costs:
- Ultimaker Eines Rambo 1.1. 120 $ / Prusa Einsy 119 €
- 5V fans about 15 €
- Generic 24 V Power Supply 12 €
Total: about 145 €

Option 2 - Switch/Add the stepper driver
- Requires separate board and some easy soldering
- Costs can be reduce by upgrading not all axes
- Going back to original drivers is very easy (just plug the motors back to the RAMBO)
- Stepper drivers will be operated in standalone mode or controlled via SPI
- You might run stock MK2 firmware. However, slightly modified firmware is required if you aim for lost-step-detection
Costs:
- Genuine Watterott TMC2130 drivers 22 € / 33 € (for 2 or 3 axes)
- Generic 24 V Power Supply 12 €
- Extension board: Build your own ??? € / PRUSA MK2(S) EXT. DRIVER BOARD V2.3 by Antonio Velkov 29,99 €
- Optional: Arduino Nano 6 € or Raspberry PI for SPI control
Total: about 45 - 80 €

if you just want silence, you change X,Y and use TMC2100's and set the current on the pot, they're cheaper. if the motors have whine (where the chopper freq is in audible range) then you use a DC-DC step up to 24V (or whatever is best).... I got 6A step up for maybe $10? Total cost is maybe $25? $30?
