A10 w TMC2130 on gt2560 v3
Posted: Sat Aug 01, 2020 1:58 am
Hi, spent few days converting my A10 to tmc2130 powered A10.
My current A10 is quite upgraded: it has 3dtouch configured with UBL ; bowden extruder and hot end from cr-10spro.
for UBL config and i still have screen and SD card support.
For UBL I step by step followed Chris basement tutorial : https://www.youtube.com/watch?v=ONpKxkil16Q);
Converting a4988 to tmc2130 with sensorles homing required some cleaver approach due to no spare SPI pins.
My convertion was based on Chris basements video https://www.youtube.com/watch?v=kMICfCa6bHk&t=790s
TMC2130 set up configuration was also partialy covered in detais by Teaching Tech's ant Tom Salanderers videos.
So 2560 v3 board has few spare pins so conversion can be quite easy . First of all gt2560 is by default partially soldered for 3 extruders... So in my setup i had E2 unused as it has no ports also on gt2560v3 there are A0-A7 pins made accessible.

GT2560 v3 pinout from marlin pins_GT2560_v3.h for E
#define E2_STEP_PIN 43
#define E2_DIR_PIN 45
#define E2_ENABLE_PIN 41
So basically there are plenty of pins for 5 axis A10 convertion to TMC2130 spi set up w sensorless homing.
So for 5 axis setup :
1) - need to prepare TMC2130 drivers for spi configuration >>>>> soldering involved >>> in my case i bought BTT TMC2130 v3 stepper drivers and some soldering required as shown in Teaching techs video from 9:35 (https://www.youtube.com/watch?v=OUadiW5QLBE)
- also cut of downwards facing SDO, CS, SCK, SDI pins as only upward facing are needed.
2) buy or prepare conecting wires for spi.
3) remove fan from mainboard chamber cover is with additional wires for SPI connection there arent enough space to fit it. think an external way to attach it.
