Manta m5p TMC2130 SPI configuration

General Discussion

Basic Information:

Printer Model:
cetus3d
MCU / Printerboard:
bigFreeTech manta m5p board
klippy.log

any ideas what i can do to make it work?

The first thing you can do is follow the instructions you were given when you did the first post.

Attach your 'klippy.log as a file, don’t cut and paste it into the post.

apologies, first time posting on a discourse, original post is edited

If I’m reading the klippy.log correctly, Klipper is unable to communicate with the TMC2130s on your board.

How did you set the jumpers on the board and are you sure of your IO pins (especially for the SPI bus)? What references did you use?

i used the following manual to configure my board

i connected m1 m2 m3a and m4 like the screenshot above so driver is configured for SPI and diag pin is connected

for the rest the only thing i have connected to the board is the temperature sensor for the extruder

also worth noting is that i used the default manta m5p config from klipper and then tried adding the tmc 2130 with virtual endstops but it never worked

In your klippy.log file, you have defined your SPI pins as per:


[tmc2130 stepper_x]
driver_sgt = 63
cs_pin = PD9
spi_software_sclk_pin = PA5
spi_software_mosi_pin = PA7
spi_software_miso_pin = PA6
run_current = 1
sense_resistor = 0.075
diag1_pin = ^!PD3

But, when I look at the M5P’s schematic:

These pins are defined for other functions:

Namely:

  • PA5: HB_PWM
  • PA6: M5-CS
  • PA7: HE1_PWM

Where did you get these pins to use? The CS pins look correct, but I don’t see any kind of connection between PA5-PA7 to the TMC2130s.

I think you should be using the “LCDSD” pins which are PB13-PB15 (they go through level shifting buffers U18 & U20) and get converted to “MOT” SPI pins.

hey ive tried setting software spi to pins PB 13 - 15
and using spi_bus: spi2 as per reference config

please find them in the last 2 runs in the klippy.log
klippy.log (1.6 MB)

still same result

Check your config against https://github.com/bigtreetech/Manta-M5P/blob/master/Firmware/Klipper/generic-bigtreetech-manta-m5p.cfg

i reset back to the config given here with the following changes

commented out heated bed as i don’t have it hooked up
changed extruder sensor type to PT1000 (I have a PT100 for now but it registers in klipper)
removed the comment of tmc 2130 stepper x

for the rest i didnt change anything

Triple check your board jumpers. From your pictures above, I doubt that they are correct:

  • TMC2130 are no HV drivers
  • Acc to your config, you do not use sensorless homing, so the diag jumper seems wrong
