Hello ,

I got maybe an issue , by connecting everything to my board.

4 stepper drivers for 3 axis and extruder

I was doing some work on my heatbed so I moved the carriage on my X axis
and I heard the high pitch sound , which can be heard if you normally turn the power off.

with the Z axis and Y axis I don't get the "power feedback thingy"

I measured the cable to exclude a faulty cable

My printer is an XYZ Davinci Pro 3 in 1 , I rewired the whole printer and I will be using only the enclosure ,the stepper motors from the original

who knows what is going on ?

Hello, I am attempting to use driver 3 and was specifying the pins used here. PA0 is the pin used for the heater, and when I attempted to use !PA0 my hotend started heating. Luckily I caught this before something bad happened but my god, please get the pin mappings correct.

Now I don't know what the pins used for driver 3 are.

Hi,
I am wondering if it is possible to flash the firmware on my Octopus Pro V1.0 with vscode/platformio using the USB-C connection.

this is my platformio.ini setting:
[platformio]
src_dir = Marlin
boards_dir = buildroot/share/PlatformIO/boards
default_envs = BIGTREE_OCTOPUS_PRO_V1_F429_USB

in plotformio device list the board shows up as COM12.

building the Marlin firmware and flashing it using the SD card works fin, but as soon as I want to directly flash it using thw USB-C connection I get the following error:
Uploading .pio\build\BIGTREE_OCTOPUS_PRO_V1_F429_USB\firmware.bin

What do I do wrong? Or is the board not able to be flashed usinf the USB-C port (hope not...)?

Hello,
I noticed an error in the pinout diagramm of the Octopus Pro board.
The pin 'PD11' ist listed for BOTH FAN4 AND DRIVER1 CS. I guess FAN4 pin should be 'PD14' like on the normal Octopus V1.1 board?

I am struggling with the combination of Octopus Pro & MicroProbe V2.0.
Is there anyone out there who has gotten it to work well?

User error - delete issue

Can not find any description for a new 1.0.1 pro board (429) where is explained the function of that tactile button switch next to the SD slot and aligned with a wifi card black connector.

This is about the F429 variant:

There is a trailing "comment" in the memory map in the USB interface descriptor for the Internal Flash device:

iInterface 4 @Internal Flash /0x08000000/04*016Kg,01*064Kg,07*128Kg챐ƨ⹔뺿䭼뛮컸

챐ƨ⹔뺿䭼뛮컸 translates to English as "It was so big".

This can be observed with the device in DFU mode with the command:

lsusb -d 0483:df11 -v

dfu-util (v0.9) tries to parse this string and fails with the message:

dfu-util: Failed to parse memory layout

Please update the bootloader to remove this string.

see also: https://klipper.discourse.group/t/make-flash-octopus-pro-board/11953/5

I am trying to set the board to have dual Y axis, but am struggling in understanding how.
Which config lines should I modifiy?

Is there any way to have both SD Card and USB Drive work together. If I enable #define SDCARD_CONNECTION LCD and #define USB_FLASH_DRIVE_SUPPORT I can only use USB Drive. when I insert SD Card nothing happens. also when I enable #define MULTI_VOLUME when I insert SD Card nothing happens too, but when I also plug in usb drive I can access both SD Card and USB Drive. Is there any way to make it detect both SD Card and USB Drive?. I used latest Marlin 2.1.2 release

Hey,

i am using Octopus Pro with TFT70, and whenever i configure PT100 with the board in marlin bugfix, it shows "no printer attached"
if i use normal thermistor in the configuration it works well but with the PT100 it is not.
i have done everything with the configuration but it is still same.

so please help me to remove this tag from the screen

The PE11/GND pins are reversed in the color version of the pin diagram for Octopus Pro. The other, older version, is correct.

hi, how configure the jumper for a NTC 100K for an ender 3 mk8 hotend stock,please ?
in the doc, i can look for a PT100 / PT1000 with 2,3,or 4 wires, but don't look for a NTC100K

thanks

Hallo,
can the btt octopus pro v1.0 read the sensor data via a adafruit max31856 of a thermocouple type j? I connected the max31856 over the exp1 and tried the spi3 but im getting no signals.
Here are the codes that i use:

I have a 446 and I can get it into DFU mode no worries. (BOOT0 is fine)

It flashes klipper and reboots into it fine.

But if I remove the boot0 jumper, it just doesn't work.

And after this, if I check dmesg

So it's definitely booting klipper. But now if I turn it off remove boot0 jumper, it will not boot at all.

So I assume boot1 is broken?

How can I reflash it to get it all working again.

Board intended for 4 Hotends.
so ... multimaterial is choosen and requires more than 300C (even such is only by some, most thermistors works till 280С ) - then inputs T0-T3 will be useless.
One Input for PT1000 solve not control of individual heating.
connected thermistors at "300С+" will be dead, replacements to PT100/PT1000 - no t enough connection points
seems that was only single-head-extrusion developed on that board . /also as lower model without "pro"/

example:
Support material = solvable PVA = low themperature 200-230С - can be used on thermistor
3 Main Materials ( as PC =310, or PEEK =360) => 300С+ => only one of them will be controlled on PC1000 input

With the MCU Power Jumper in place can the USB-C connector be used as both power to a Raspberry Pi 4 and for serial communications. It looks like it can, but I don't see this mentioned anywhere.

I have a problem where the jumpers for the DIAG pins to run sensorless homing, have no connection to the pin of the endstop.

Is the H729 a newer version???

I get a new H723 and find a broken spi1 connection on the PCB to the driver.
Workaround is to use PA6 of EXP2 and connect it to the driver line by using a jumper cable.
May it run into other electrical issues by doing it?

MAX31865 is working fine.

Hi,

I am trying to use a PT1000 with the MAX31865 module plugged into Motor7 slot on the Octopus Pro 1.0.1. The printer reports a MINTEMP error for the temperature when I have the LCD controller EXP2 is connected to the Octopus Pro EXP2.

The printer can successfully read the temperature ONLY if I disconnect the EXP2. I am using the ULTICONTROLLER LCD with my board and it's EXP2 pin out is the same as the standard LCD EXP2.

My pins configs is below. I commented out the MAX31865_CS_PIN listed in the BTT MAX31865 manual because it seems that TEMP_1_CS_PIN is now used in the latest Marlin instead of MAX6675_SS_PIN. Is my configuration correct and is there a solution to use the LCD mounted SD SPI and stepper motor SPI at the same time?

//Define E3 or TEMP_SENSOR_1 on MOTOR 7

I'm building my Voron V2.4 based on Octopus Pro (STM32F446). According to the wiring doc (https://docs.vorondesign.com/build/electrical/v2_octopus_wiring.html), I connected my hot-end heater to the HE0 screwed connector (PA0 pin). When my assembly was complete, I started testing the heater. I set the target temperature to 50 degrees. Mainsail UI showed me that heating was started, but the temperature was not growing and after a few seconds Klipper reported a heater error and disconnected.

I double-checked my wiring. Everything seemed to be fine, but the heater did not work. Then, I tried to measure the voltage on the screwed connector HE0 after triggering the heater one more time, but the multimeter showed zero.

Then, I changed the Klipper config to use PB11 as a heater pin, reconnected wires to the HE3 connector and everything started working as expected.

Does anyone know what could be wrong with the HE0 connector? May it be due to misconfiguration or my mainboard has a defect?

I'm using Marlin 2.0.9.3 and windows. I have been successful in uploading firmware but when it comes to connecting the board to my computer (I'm using pronterface) it won't connect. Before you give me the same responses that I've been getting from everyone on the internet.

Yes I have set serial port 2 to be -1
Yes I have tried to update drivers (couldn't really find them though)
Nothing shows up on the device manager

I'm probably doing one small thing wrong, but any help is appreciated

jumpers double checked under the driver module, no idea how to continue?

Hi

What is the pin to which "SPK1" is connected?
If it isn't connected why include a speaker onboard?

I have the Octopus Pro v1.0 board with the stm32F429 to replace the original board of a Sunlu S8 Plus. Pretty much the rest of the sunlu S8 is original, so by configuring the Octopus Pro with 1 x driver, 1 y driver, 2 z drivers, and 1 extruder driver, the extruder is the same as the z-axis ones, like if it worked in parallel, and it seems to me that it specifically copies the z2 driver, since by disabling Z2_DRIVER_TYPE the extruder driver stops working completely, along with the z2 driver.
This issue occurs in firmware 2.0.9.3, 2.0.9.5, 2.1.x, 2.1.1
I would appreciate the help.
These are my configuration files:
Configuration.zip

According to the sales website and manual, Can bus is still over RJ11 connector. Not the XH2.54*2Pin connector that is stated on the GitHub page

I have tried every combination possible to use the onboard MAX31865 chip so i can run a PT1000 on the Octopus Pro with klipper, no matter the settings the error says EXP_1 or EXP_2 in use as they also use the SPI bus 1, I know many others have had this problem, There has to be a way to use this sensor which is one of the main reasons I purchased this board, is there some work around or a specific config I can use to allow me t use both the display and the PT1000?

The value for the MAX31865 Reference Resistor is not noted as far as I can see, this is a needed value for configuration. Is it the standard 430 resistor or something else?

Hi all,
I would like to connect my NEMA 23 to the Octopus Pro.
I have the drivers for them which are (by title) TB6560.

I would like to know which set up should I use since I changed some information in the code (changing the driver), but I think I am missing something in the jumper set and probably in the wiring too.

I used a sort of "blank" drivers to attach the externa ones (the one in the picture).

From that I used the same wiring setup I had on a another board I used to use with raspberry (the protoneer). but it does not move at all.

I have for now all the jumpers under the driver.

Hi, I am using Octopus Pro + TMC5160 Pro (printer RatRig V-Core 3)
I use 24V PSU and 60V PSU only for XY steppers.
If steppers are enabled, hotend temperature with 2 wire PT1000 is unstable, it jumps +-2°C
Issue will disappear when i disable steppers.
How to solve this, please?

Even in the latest version of the Marlin firmware, there is no definition to support the H723ZE chipset in the boards.h. How do I use it?

How can I get the ez5160 pro's diag pins to be used on the octopus pro board?
The ez connector diag pin is located on the clk of the octopus pro board.
can you make another ez connector for octopus board?

Issue:
The SPI bus cannot communicate with the “TMC5160 PRO” driver.

Notes:
• STEP/DIR work.
• Not able to communicate with SPI
• Tested two TMC5160 PRO drivers with the same result.
• Octopus Pro V1.0 STM32F429ZGT6
• Using the latest Marlin Firmware from (https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0.git)

many of ESP12-(S/*) modules on amazon/aliexpress/ebay have other pinout (on silkprints they are same for available same-sized ) as on BTT used
make sure and at least take a look on position of GND and 5V pins
other pins are questionable ...
if you have/bought such - will be needed an adapter

I have the next hardware:

• Octopus pro F429
• U2C module

According to pictures for the canbus on the octopus. I have to connect the octopus USB-C port to U2C USB-A port.
But i can't get this to work. I did put the bridges for the USB-A to enable

I have flashed the octopus with al kinds of firmware and settings.
What works is the RJ11 connector. When connecting th SB2209 to the RJ11 and the USB-C to the raspberry pi, then everything works.

But that is not how it is in the manual.
Please post a link how to configure the firmware to get the USB-C to connect to the USB-A, all in canbus

Can I plug a USB wifi adapter into the USB-A port instead of buying a ESP wifi module?

The F429 version of the Octopus Pro v1.0 can be flashed via DFU over the usb-c port, but unlike the F446 version of the same board DFU-UTIL is not able to reboot the board in DFU mode and flash it.

It is probably just a matter of having the F429 bootloader updated so that dfu-util can reboot the board in DFU mode and flash it, verify and reboot in normal mode without any physical interaction, like the F446 already does.

Hello,

I am thinking to use octopus to control a 6 axis robot, is there is a way to develop a new firmware for custom applications. Unfortunately i cant able to find source files any API or header files specific to STM chip in the source files that I can use to develop, If any one created own firmware using Octopus pro please help with the process

Thanks in advance

I have a bunch of BTT TMC5160 Pro v1.1
I used them on MKS Monster 8 v1.0 without issues.

But on BTT Octopus Pro v1.1 STM32H723
I got "Unable to write tmc spi 'stepper_z' register" issues while executing Home actions.
In SPI bus settings I tried software spi pa6 pa5 pa7 and spibus : spi1. I also tried to set spibus speed to various speeds, all yield the same error. CS pins are configured correctly.

I read that v1.0 and v1.01 versions have the PA6 MISO diode issue.

I checked the forward bias of my diode is 0.57V, the direction is also correct (cathode properly connecting to buffer chip output and anode to pin 42 of mcu).

Also the motor driver MISO is properly connecting to thr input pin of the buffer chip.

Can anyone point me towards some directions?
Anyone got success with Octopus Pro v1.1 and TMC5160 Pro v1.1?

I do not want to jump wire the MISO from driver directly to pin 42 because this may fry the input pin of the STM32H723 MCU as the Maximum Absolute Input voltage of this MCU is just 4.0V as stated in Datasheet.

Looking for an direct alternative to connect a second LED bar on the board besides the neopixel port PB0

The Readme lists a table of pinout changes for the Octopus Pro v1.1. It incorrectly shows that Motor4-EN has changed from PA0 to PA2; however it is actually Motor3 that has changed.

They run for couple second but then this error massage ,and same error after restart.
My thorough research seams 8 mhz crystal on 429 version causing the problem need 12 mhz version please correct me if Iam wrong and help me find a solution.(it is not wires problem wires are all brand new Ldo , and same board and motors run perfectly fine on BTTtmc 2209 with no problems.power supply meanwell 24 volt 600watt power supply .
Thanks.

The Octopus pro V1.1 board with the STM32FH723ZE chip is lacking with clear information. I feel like in an effort to save time any information on that particular board was vaguely put in the margins of manuals with a similar layout. To me it screams lazy and does not make that part of the build process possible to move forward confidently without stress of ruining the board.
