Hello,
I wanna add a MAX7219 led matrix to the SPI port close to RGB pins.
Can´t find in definition or scheme what are the corresponding pins in mcu or if those pins are share with other devices.
Can you clarify it?
I´m not gonna use SPI steppers, but I´m using sd reader at exp2.
Thanks

A problem in the software or a marriage of the board?

I am using the S6 board for a telescope project (OnStep).
It works, and controls the scope as expected.

The issue is that connecting I2C devices (e.g. BME280 for ambient temperature, pressure and humidity) does not work at all.

• connect SD card module and see content (m20 g-code)
• place firmware.bin to SD card, power on and nothing. I see previous firmware

Dear Fysetc guys,

Can you please assists me. I've ordered your motherboard S6 V2.0 in order to upgrade my Ender 5, and want to know if i connected all the jumpers correctly. Please see the picture.

Also I've ordered TMC 2226 drivers, are they compatible with that motherboard?

Which parts of the software i need to adjust for Ender 5?

With best regards,

Jevgeni

Hi to all.
Help will be advance appreciated.
My project is a OnStep conversion for my telescope to replace DC motors with Step motors.
Trying to flash my board I get the following meesage,
14:39:33 : RTS low
14:39:33 : DTR low
14:39:33 : Serial Port COM6 is successfully opened.
14:39:33 : Port configuration: parity = none, baudrate = 9600, data-bit = 8, stop-bit = 1.0, flow-control = off
14:39:35 : Timeout error occured while waiting for acknowledgement.
14:39:35 : Timeout error occured while waiting for acknowledgement.
14:39:35 : Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...
As it says port is oppen, but do not know what to do! I looked to assure the jumper in BOOT0 was porperly done, also have 5v thrugh USB, verified cable connection, Also I had reinstalled SMT32CubeProgrammer, all my thoughts to define the problem had exausted.
As you can see, I'm very limited and would like to flash the board and get to next step, to be able to do bench test.
All recomendations and help will be appreciated.
Miguel.

So, today I have installed a S6 board on my ender 3. Drivers, endstops, stepper motors, bed and hotend work find, but I have a strange behavior when I power on pwm layer fan. Infact in FAN0 connector it run always at 100% of speed. If I connect the fan on FAN1, it is always off. At last, if I connect the fan FAN2, finally it works as aspect ( pwm mode).
I want to specify that the hotend is connect to E0 24V connector, and the thermistor is connected on TE0 connector.
Could anyone explain me this behavior, or help me to resolve this?
Thanks

btt tft35 connection

Which pin can I use when connected?

I am using the S6 board for a telescope project (OnStep).
It works normally for most functions.

However, when having the GPS connected, the board would not enter DFU mode when the BOOT0 button is pressed, then USB cable is inserted.

If I disconnect the 5V going to the GPS, then DFU mode works normally.

Any idea how to solve this?

Hello all I have a Fysetc S6 V2.0 board. The eeprom will not retain the program after reboot. I think I have everything enabled it's just not persistent

Hello, I ask for your help, fysetc s6 v1.2 and tft81050 when connecting bltouch before parking the printer does not raise the z axis when AUTO_BED_LEVELING_BILINEAR the z axis also does not rise after the first touch.

hello I bought a S6 V2.0 board and i have a question about power supply.
Can i use a 24V power supply for power input and a 12V power supply for bed only (using bed in)?
In this configuration the GND must to be common or not? And the hotend’s heater in this configuration (24V in) goes at 24 or 12V?

If you use the NVram at location 0x50, data to all other devices are corrupt. Meaning I2C is unusable.

To reproduce problem. Access NVram, then access another device on I2C. Such as BME280 or DS3231.

I'm having a problem.
I installed the cables as shown in the figure below:

BL Touch is working.
I can test it out.
But when the BL TOUCH touches the table, the Z Axis keeps descending without stopping.
I have to turn off the printer quickly.

Hi,
i've got error with new bootloader and klipper firmware with S6 board.
Firmware uploaded using STM32cube and DFU.
Sequence:

1. Enter DFU Mode
2. Upload Latest bootloader
3. Restart Board
4. Upload latest klipper compiled firmware. Start address set to 0x08010000
5. Flashing successfull
6. Attach S6 to RPI
7. Starting Klipper, Firmware working OK, I can print
8. When I reboot board with BOOT jumper set to DFU - it goes to DFU mode (expected)
9. Whet I remove DFU Jumper and reboot board - USB cannot detect board anymore. It becomes brick.

I can repeat steps 1-7 to make it work again, but it is not expected scenario.

Please, advice what to do with that, thank you in advance.

Hello all,

I migrated from a F6 board to the S6 board and was testing my functionalities. I encountered an issue in which my print fan is not controlled properly. When controlling the fan via repetier or the LCD, it does not start until I reach 95% of the PWM. In the region from 95-100% the fan just turns on with maximum speed. No PWM change is observed. I did not change any settings (except the correct pin assignment within the S6 fan connections) between the firmware for the F6 board and the S6 board. What can cause this issue?

Below are some specs of my setup:

• Firmware: Marlin 2.1.2.1
• Board supply: 24VDC
• Fan supply/type: 12VDC (also connected the jumpers on the board to 12V)
• Normal PWM mode (i.e. No fast PWM defined)

Please let me know if you need any extra info.

Thanks in advance!

Hello.
A defective endstop and/or a probe can feed voltage (let's say 24V) directly into the STM32, burning it. There is no diode or current limiting device on the endstops.
Any idea why?

I have the FYSETC S6 2.0 card and I'm trying to use the TMC2209 V3.1 driver
I'm using the FYSETC MINI 12864 V2.1 panel with SDCARD.
The TMC CONNECTION ERROR message appears on the panel when I turn on the card.

I'm trying to test the engines with Marlin BUGFIX 2.0 and 2.1.
It is returning the same error.

I always get the message 'TMC CONNECTION ERROR'.
Even if I put it in the 24v source with the pins in DC5V or in the USB.
Even if I put the pin on 5V and DC5V.

I'm trying to run TMC2209 V3.1 in UART.

Hello,

I have FYSETC S6 powered by 24V DC Power Supply. Measuring +5V and GND from UART Pin, it reads 4.95-5.0V as expected. However, when I connect Raspberry Pi to USB plug, +5V changes to 4.3-4.4V. This makes my PT100 amplifier inaccurate as it needs 0V and 5V inputs, not 0V and 4.3V input.

If the control board could use internal 5V2A supply even when USB device is connected, it would work better.

After a bit work I was able to get a generic "blink.ino" sketch uploaded and running when using the Arudino IDE and the settings found here: https://onstep.groups.io/g/main/message/43912 and changing the upload address to 0x08010000 in the "stm32CubeProg.sh" script. ( 0x08008000 doesn't work even when I use the newer bootloader, not sure why)

However when I upload the same code using platformio the program doesn't run after uploading. Here is my current is .ini file for platformio:

[env:fysetc_s6]
platform = ststm32
board = fysetc_s6
framework = arduino
upload_protocol = dfu
board_upload.offset_address = 0x8010000
build_flags = -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC -Os

Does anyone have any tips to get the DFU upload working in plaformio for the S6? I assume I could use the same .ini which is used for the marlin build but I can't seem to figure out all the settings since many of the settings are found in separate scripts called by the ini file.

The output from the terminal during the upload:

Wrong default TX RX pin definition in latest Marlin version

FYSETC S6 is proving a great board for klipper. and in conjunction with a RPI Z2 and Fluid/Mainsail is almost a perfect setup for most people to use or upgrade to.

the only issue thing that stops me recommending this as 100% perfect is that its not currently easy to upgrade the MCU firmware when klipper is updated without disconnecting the board from UART and rejumpering to setup for USB.

Section 3.3.2 of FYSETC's own wiki states this should be possible
The UART socket next to the limit switch can be used to connect serial devices such as the wifi module, or to update the firmware through the serial port.

Recently FYSETC released a bootloader compiled for the similar Spider board which uses the same MCU as the S6.

therefore quick questions :-

1. Can anyone tell me if a suitable equivalent is available for the S6 that i'm missing or havnt found
2. could I load the Spiders bootloader firmware (klipper-32k-Uart.bin) on the S6
3. How involved would it be to compile a suitable bootloader for the S6 that enables serial uart flashing
   and finally is there any other way to flash over the RPI serial UART that would work without needing a special bootloader ?

I am unable to find any info regarding v2.0.

Hi, not sure this is the right place.
I tryed to upload new bootloader 0x8000 with stcube.
Once loaded, always with dfu and VScode I uploaded Marlin S6_8000 env but once I reboot (boot jumper and power off/on) no usb port happears.

Since it doesn't work I re uploaded boot_10000 and marlin s6 env and it works.

What's wrong?

Hi,

I received my Fysetc S6 1.2 today and noticed that the silkscreen designators do not match the schematic. For example, on my board Z+ is labeled with PB12 but the schematic says Z+ is PA3. Is this an error on the silkscreen or does my board have a different pinout?

Thanks
Felicia

I like a lot this board, but a thing I miss a lot to use it is a drawing with the correspondent pinout in place, so I wold like to know if you could provide some good stuff in this way.
some like this:

or this:

Thanks a lot.

Hi,

I've got the S6 2.0, running Klipper with an RPi3B.

A couple of weeks ago Klipper was updated and I needed to update the firmware. It's a procedure I've done previously but since I don't do it often, I can't say I'm able to do it in my sleep. Now, for some reason after updating the firmware, the card's not found in fluidd. I figured that I must've done something wrong and at this point I feel like I've tried everything at least three times and that I have a feeling the card is borked.

The last thing I've done is that I flashed it with the STM32 CubeProgrammer software, and reflashed the bootloader (64k version) starting from 0x08000000 and then flashed my klipper.bin starting from 0x08010000. The klipper.bin I compiled with low-level extras enabled, STM32F446, 64k bootloader offset, 12 MHz crystal, USB (PA11/PA12) as comms interface. Didn't touch USB ids nor GPIO-pins.

After flashing, I powered off the board, removed the DFU-jumper, reconnected it to the Pi (USB) and run "ls /dev/serial/by-id/*" which gives me "No such file or directory".

I also reinstalled my fluidd so there's a possibility that I've messed up something with the configs as I used to have the controller connected to the Pi with UART and not USB.

I'm not sure what more information you need, but I'm happy to provide any logs or whatever could help anyone to figure out the problem.

Thanks!

Top right of the board

Please tell me the pin number of the FFC connector

Is there a difference between the pinout of version 1.2 and ver. 2.1?

According to this diagram, E2 heater is PC8:
https://github.com/FYSETC/FYSETC-S6/blob/main/hardware/V2.0/S6%20V2.0%20Postion.pdf

But in this diagram, PC8 is given as the bed heater output: https://github.com/Klipper3d/klipper/blob/master/config/generic-fysetc-s6-v2.cfg

I have found this to be PB15.

HI,
I read on the onStep wiki that it is possible to connect the ST4 to the board.
The connection requires the use of "2.2K Ohm bussed resistor network 5-pin".
I wanted to know:

1 - Is it necessary even if SHC is not used?
2 - How do you connect the cables of the ST4 cable with the bussed resistor and then everything on the exp1?

Thanks in advance
Alessandro

Please add the .step-file for the v2.0.
I want to make some closures but no CAD-programm can read PDF3D-file.

I am running the S6 board with the Fysetc TMC2209 drivers and every time I enable TMC_DEBUG in configuration_adv.h and upload the firmware to the board, I do not get serial communication from the USB port after rebooting from a firmware upload. With this disabled I don't get the full diagnostic information when sending an M122 command. I have posted this problem in multiple places (Fysetc forum, contact form on their website and tried to join their facebook group) and have not received any response from Fysetc tech support from ANY of my posts. SO now I will try here.

Hello all,

I purchased a S6 board (to replace my F6 board) and I would like to connect my BLtouch to the board. I unfortunately saw that the BLTtouch PWM connector should be connected to the Z-max pin. In normal operation, I use the Z-max endstop for homing. Therefore, I want to utilise both Z endstops (Z-min for BLtouch, Z-max for homing). Are there any alternative pins to connect my BLtouch PWM connector? If so, which pin do I need to assign to Servo0. In extend, if possible I would like to keep the 3 pin connector assembly (i.e. not connecting single BLtouch wires throughout the board).

The S6 V2.x board runs on Marlin 2.1.2.1 firmware.

Please let me know if you need any extra info.

Thanks in advance!

Hi

added the STMduino library to the Arduino, and can now select the S6 board in the menu
but the arduino IDE does not show any port available

do I still need to flash the firmware?

tried the ST cuberogrammer route- but no connection possible (after boot button procedure)

thx

I know that 2.0 board is on development and I know that some TMC drivers have a lot of issues (they die) when vmot is missing but vin is present. To solve this issue it's a common way to use vin with a diode to power vmot.

I don't know if 2.0 may be powered (via usb?) with no 12/24V. In such case TMC lose their cnf and requires a reset + reprogram when 12v/24v is given (I noticed this acting at reverse, tmc fully programmed and removed 24V, once 24V comes back tmc 2209 registers are wrong).

There are some issues reported in Marlin about this weird behavior. On a different test board (ramps) I solved this powering TMC vmot with 5V + diode. It seems that 5v instead of 3.3 solve the issue.

Since I'm looking for 2.0 board it would be a good thing if it may solve such issue

Thanks for your attention

Can someone explain in very simple terms how to "cut the jumper" so I can run a PT100 through an AD597K board?

Hi, how do I connect the endstop from ender 3 to fysetc s6 v2.1?

The 10K R24 pullup resistors are not populated on board Version 2.0.
This should be reflected in schematics

I'm facing a very weird issue with bootloader. I'm using an old 60x sd card, 256MB, FAT32, with firmware.bin file in it.
When I turn off and on it seems to hang (SD is on LCD).
During boot lcd is clean and stay clean
Very often it hangs, some time boot without updating firmware (rare) and some time it works correctly.

Anyone else had this issue?

Is boot source available that may let me fix it by myself?

Hello. Can i upload g-code from usb disk (like on skr2 or robin nano v3), or only sd card? If not what needs to be done for this?

Hi, I have a SPI TFT with touch and SD card (http://www.lcdwiki.com/2.4inch_SPI_Module_ILI9341_SKU:MSP2402), all using SPI for communication. When I use the TFT and touch in SPI1 both works fine, but when I use the SD in the same MISO and MOSI, the TFT and Touch became unstable, so I decided to use the SPI3 (PC10 for SCK, PC11 for MISO and PC12 for MOSI) for SD and SPI 1 for TFT and touch, so I see that the SPI3 didn't work. I tried to invert and use just TFT in SPI3 without sucess.
There are any way to make the SPI3 to work?
I don't use SPI step drives, so, if there are no way to use SPI3, is there are any way to use SPI2?

I am using Klipper firmware for Fysetc S6(version 2.1) board. I installed Fysetc S5160(version 1.2) driver to X and Y driver sockets. I am getting "Unable to write tmc spi 'stepper_x' register GLOBALSCALER" error in both slots. 4 jumpers are installed on bottom positions as described in the README. TMC 2209 drivers work in these sockets with UART configuration. I tried 4 different 5160 drivers so this shouldn't be a faulty driver issue.

Klipper docs say that this error might be the result of shared SPI bus:

Note that if the driver is on a shared SPI bus with multiple devices then be sure to fully configure every device on that shared SPI bus in Klipper. If a device on a shared SPI bus is not configured, then it may incorrectly respond to commands not intended for it and corrupt the communication to the intended device. If there is a device on a shared SPI bus that can not be configured in Klipper, then use a static_digital_output config section to set the CS pin of the unused device high (so that it will not attempt to use the SPI bus). The board's schematic is often a useful reference for finding which devices are on an SPI bus and their associated pins.

I looked at the schematic but I couldn't find out if the SPI bus is shared. Sample config file for F6 has a static_digital_output section but sample config file for S6 doesn't have it so I am not sure.

Try to use more than 2 I2C devices and the board locks up. this is with the latest 2.2 library .

Yo!

So I'm slightly confused about the documentation regarding this feature:

"Limit switch socket 24V/5V/3.3V optional, ready for more other equipment, such as -inductive sensor, BL-Touch"

I've got a couple LJ12A3-4-Z/BY lying around and the only problem I see in using it, is that the signal going to the MCU would be 24V. I've been looking at the schematic for the board and I can't see there being any components to pull that voltage down.

Am I missing something or is there an undocumented way to connect it without extra components or do I need to solve the 24V to 5V signal some way with extra components?

( The printer is an Ender 3 with the Fysetc S6 2.0 running Klipper. )

Hello,

ive been following

Enter DFU mode first

    First power off the board
    Set jumper on 5v pin and DC5V
    Place jumper on BT0 to 3.3V pin
    Connect USB cable to the board and your computer
    Power up the board with 24v

I tried 2 different cables but i cant get it in dfu mode. is there anything different on 2.1?
