New Trinamic Stepper Driver, completely silent.

Hello all,

Some of you, who remember me, may know, that I have been using a trinamic control board to control the motor due to noise with the regular drivers.
There were a couple of problems with this solution:

- driver board is kind of expensive (about 100 Eur), since it's 3 axis.
- I had to write custom firmware, since it doesn't support gcode.
- it had to be wired up with a USB-Serial adapter, another possible point of failure
- i couldn't use nanodlp's Z Calibration features

Now, I present to you, the best of all worlds: Silent Step Stick!

It's a absolutely noiseless Trinamic driver in a stepstick compatible format. Now i can natively drive the motor in nanodlp.
There are a couple of things to read to configure the correct microstepping but the pins for voltage and enable etc. are compatible with other modules, so this whould work with shahin's schematics too.

Re: New Trinamic Stepper Driver, completely silent.

I've just replaced my A4988 with TMC2100 5V on my mUVe 3D printer. I can confirm, these new drivers are absolutely noiseless! I am very happy with this improvement, because my printer is sitting in my home and now the only sound from the printer come from the projector fan!
Thank you very much for shering the iformation about Trinamic drivers, adam.
P.S.
The only thing you must do after replacement is changing the step direction of the motors in Marlin firmware and set the current with the little screw on the drivers.

I have read that for 3D printers it better to turn off silent steps (stealth mode I guess) but without it, it sounds worst than other drivers. (I have TMC2100 too)

Re: New Trinamic Stepper Driver, completely silent.

I am using 16 microsteps with interpolation to 256 in "spread Cycle" mode  - CFG1/GND, CFG2/Open. I even not tryed "stealt Chop" because in RAMPS MS1 pin is tied to GND. It is very strange that your dirvers work worst than A4988

Re: New Trinamic Stepper Driver, completely silent.

I have also installed the TMC2130 driver and they are indeed very quiet. I had to star at the printer axis to check if it was actually moving.. smile

But the TMC2130 driver has a reverse direction pin. How can we reverse the direction in nanoDLP (direct GPIO control)?
