Rumba with TMC 2130 driver

Has anyone experience with TMC 2130 drivers on a Rumba board?
I watched Tom's video on the TMC 2130 and how to hook up to Ramps. But not sure how to apply it to my Rumba. Found a Rumba on Ebay with standard mounting.

Its almost identical (just different pins)

Firstly get the latest marlin installed on your board as normal, as firmware is most of the battle

The driver are still wired the same way with the 4 pins up

You use the ISP1 port to get your SPI pins (MISO, MOSI, CLK (all 3 of these goes to each 2130)
You then need to find some free io pins, one for each 2130 this is how the controller selects which tmc 2130 its talking to. There looks to be a bunch available on exp3

Update your pins.h with the io pins you used, and check for any conflicts (ie nothing else can use these pins)

enable the tmc 2130 in configuration_adv.h and cross your fingers

Can any one help me with setting up TMC2130 on rumba board I also got bl touch connected already to EXP3 (pins 2,4,6 physical pin numeration )

I plan to use max 2 or 3 tmc2130 for xy and maybe z

and for extruders i was thinking about LV8729

Currently I'm using drv8825 1/32 steps

Can any one help me to set this TMC2130 on rumba board ? I can not figured out how the real pins are numerated to pin_RUMBA.h

I want to be able to use LCD also can i use some pins from exp3 connector to control tmc2130 ?

I sorted out this connections

i used MISO MOSI SCK from ISP1 connector

my three tmc2130 (CS pins for x y z ) are connected to D14 D30 D31 on EXP3 ( needed to add CS pin to rumba board at section steppers).

also Endstops are connected to TMC2130 so sensorless homing works winking smiley

| | DIR
| | STEP
| | NC desoldered and used as pin in S position on schematic to connect it to Endstop
| | SDO goes to MISO ISP1
| | CS goes to pin D14 D31 D30 on EXP3 (each CS pin goes to separate D pin on EXP3 )
| | SCK goes to SCK ISP 1
| o | SDI goes to MOSI ISP 1
| s o | En

In that way you can keep LCD and have 3 drivers connected to rumba
