HI,
Can’t seam to get anybody to help me? 13 days and no reply? Am i doing something wrong. Don’t understand, Used to get help from this website all the time!
…just installed a Sb2240, everything works until i go to purge the extruder. Then a i get this Error: Unable to write tmc spi ‘extruder’ register DRV_CONF

I feel like its a .cfg problem but can’t figure it out. Any help would be greatly Appreciated.

Thanks in advance.

I don’t know which help you are expecting.
I can look at BTT Data:

I can look at your config:

[tmc2240 extruder]
cs_pin = EBBCan: PA15
spi_software_sclk_pin = EBBCan: PB10
spi_software_mosi_pin = EBBCan: PB11
spi_software_miso_pin = EBBCan: PB2
driver_tpfd = 0
run_current = 0.650

And at the reference one:

[tmc2209 extruder]
uart_pin: EBBCan: PA15
run_current: 0.650
stealthchop_threshold: 999999

# [tmc2240 extruder]
# cs_pin: EBBCan: PA15
# spi_software_sclk_pin: EBBCan: PB10
# spi_software_mosi_pin: EBBCan: PB11
# spi_software_miso_pin: EBBCan: PB2

To check SPI, you can query ADXL.
If ADXL is working, then it is the correct configuration and then probably, maybe you have a TMC2209, not the TMC2240 on your toolboard.
If ADXL is not working, something is really wrong.

You can physically look at chips on the board to check that.

Hope it helps.

## What you get:
## - a generic fan "Nevermore" which is adjustable in GCODE and in Mainsail/Fluidd
## - Commands in your 12864-controller to turn the fan on/off or adjust in 10%-steps
## - a Macro to turn the fan off some time after the print.
##
## Slicer integration: Add "SET_FAN_SPEED FAN=Nevermore SPEED=1" in your start-macro
## (or less fan depending on your needs, like SPEED=0.8)
## in your end print code, add "UPDATE_DELAYED_GCODE ID=filter_off DURATION=180"
## this keeps your Nevermore running for 180s after the print finishes to clean the chamber a bit more.

I do have the SB2240, it was previously working. I started to have issues with my thermistor, and the thermocouple on my Ace rapido hot end. I replaced the ceramic heater and the thermocouple. eventually was able to complete a one PID_CALIBRATE HEATER=extruder TARGET=260, after that the thermocouple again gave me issues, so i replaced the SB2240 board thinking maybe that’s the problem .I completed the canbus setup with klipper. Same problem again. I then changed out the thermocouple a second time and now it works only until i try to use the extruder motor. I have tested the motor and it works as it should. I have switched drivers on my octopus with a gantry driver that i know works. Still no luck. I want to add that i did upgrade to a Meanwell LRS-350-24 power supply. Not sure that has any effect on my current problem. I will try the AXL query.

i just realized that i’m not using the octopus drivers for my extruder.

Well, this is a nice history, but it does not relate to each other and does not relate to the ability to read/write info from TMC.

Then, the only thing that I can come up with, you are not connected to DC input from your power supply, and your board is powered from USB.

In that specific case, everything, except the driver, the heater and fans >=12v would work.

Heater extruder not heating at expected rate
Transition to shutdown state: Heater extruder not heating at expected rate
See the 'verify_heater' section in docs/Config_Reference.md
for the parameters that control this check.

Well, looks like it.

In the last log lines, I see that your heater is working and connected to ebb

I have the jumper removed from the SB2240 and the Can cable is connected to the UtC. If I’m getting the picture here, The Sb2240 is not reading the TMC, which the TMC is connected to the SB2240. But all other pins that are being used are working. Hmm. I guess i can try going back to my previous SB2240 and see if i have this same problem. I changed out because i felt that the thermocouple pin out had quit working. Do you think its a firmware issue, being worst case scenario i could bite the bullet and just start from scratch and re-flash everything? This things been down for almost 5 weeks. Ready to burn it!

Thanks for your help. My apologies for my comments.

Definitely, TMC on EBB is connected to EBB, you can simply get that by the pins in the config. You always define pins from either the main MCU (without prefix) or with the prefix - secondary MCU.

In your case, the TMC Driver of the extruder is physically on the EBB board, so there is not so much freedom to do things wrong.
There are just pins, same pins are used for ADXL, so SPI is working.
CS pin looks fine, according to the scheme from BTT, it should be PA15.
TMC2240 has a switch between UART/SPI modes, but according to the scheme, it is disconnected - default to SPI.

So, the only reason when this chip will not respond is if it has no power, but your board receiving it because without power, the heater will not work.

Firmware has no clue, what are we talking about.
From a firmware perspective, there is no difference between all those pins, the same applies if ADXL works → spi pins work, so the TMC Driver connected to those pins should also be able to answer requests.

Firmware has no state, so there is no magical reason to reflash, like people like to reinstall systems or reset smartphones. It boots up, receives config from the Klipper instance, and just services the commands.

So, generally, there is no reason to reflash it to the same firmware/version/config, like “never”.

So, I think you got the idea of how it is supposed to work.

If ADXL is not part of the board, try to disconnect it, it can mess up with SPI.
Looks like it is not.

The ADXL is built in to the SB240. I guess i could comment it out.

So I reinstalled my other SB2240 (the one that had thermistor / thermocouple issues, the issue i was having with this board was that when heating it up it would take for ever to go from 180 to 200, and at 200 it would start to smoke and burn the filament. Like it thought it was at 300 instead of 200. I am using a RTD PT 1000 2 wire.) I didn’t want to wait for the system to shut down for the klippy log.

With my old sb2240 The error no longer appears, however i have the same issue with the thermistor/thermocouple.
So is it that the new SB2240 is no good? Weird that each board has it’s own issue!

klippy (14).log (1.2 MB)
I commented out the adxl, same issue.

12

The ADXL is built in to the SB240. I guess i could comment it out.

I can’t find him on the schematic.

I commented out the adxl, same issue.

Well, the whole point was if ADXL is implemented in a way to be the only device on the bus, which can be true if it is external.
If you did read the ADXL documentation above, you can notice, that it will behave in not compatible way if it is connected, not if you are using it.

So, commenting it out changes nothing.

With my old sb2240 The error no longer appears, however i have the same issue with the thermistor/thermocouple.

Unfortunately, Then I think, I can’t provide additional help here.
As you noticed, if the same config with the same firmware, works on the different board, then it means something is probably wrong with the board.

@Trev could you share how you’ve wired your SB2240? Please explain both CAN and Power along with all the jumpers you’ve installed.

Are you sure that you’ve configured your new board exactly the same way as your old board?

In my experience, when you have a TMC communications error with a TMC Chip built into the board and everything else working normally, it’s due to a power issue.

I have the SB2240 powered from the U2C through the Can hi and Can low, and the positive & ground running to my LSR 350-24. ( Black & White wire. White is live)

Which i have just installed almost as these issues began to happen. I did not check the output the new UPS, i recently did check it, it was less then 24 volts. might i have wrecked something? I have it at 24 volts now, i tried heating up and extruding, but same result.

Jumpers on the SB2240
I have a small fan in V_4W 5 VoltFan to cool the SB2240
i have the tool head fan V_FAN1 24 volt
and the part cooling fan V_FAN2 24 volt
The config is the same as i had posted earlier.

Thank you for the help.

I can see the U2C connections in image _184815 but I can’t make out the CAN connections on the SB2240.

From what you’re writing, you are running four wires from the U2C (24V/GND and CANH/CANL) to the SB2240?

Can you show the cable and the connections at the SB2240?

Can I ask why are you using a U2C adapter when there is a CAN bridge on the Octopus?

17

You are right. All the SB 2240 wiring is connected to the U2C Via can cable. The U2C is then ran by type c usb to the raspberry pi.
When I first bought the printer un assembled, I found a youtube channel called Old Guy Melts Plastic, From the bench series. He mentionedthat was better to have the octopus control the motors and the U2C control the can adapters. I had no clue what I was doing so I just followed what he did in order to upgrade to the sb2240.

Your CAN wiring into the SB2240 looks good.

I have no idea why the “Old Guy” says that a separate U2C should be used rather than the USB-CAN bridge on the Octopus.

Anyway, the particulars of the CAN connection really aren’t that relevant to this discussion - what I was looking for if you have a USB AND a CAN interface in place which could result in some power problems that could mean the TMC2240 on the SB2240 was not getting appropriate power.

Since it looks like you are powering through the just the Microfit connector then I think you’ve got a bum SB2240 board - sorry, that’s really annoying as you are replacing another defective one.

I’d suggest that you contact BTT and tell them your tale of woe (including how long you’ve been down) and see what they will do for you. While you’re waiting, I think you’re going to have to order another replacement board.

Sorry.

19

No need to apologize. If all I have to do is throw more money at it I’m a happy camper, i have more money then i have experience with this printer. Chuckles. Thanks so much for your help. I will get another replacement and post my findings.
