MKS SKIPR

MKS SKIPR is an all-in-one board launched by Makerbase for running Klipper. It integrates the RK3328 SOC running the Klipper host and the STM32F407VET6 MCU responsible for executing specific machine actions. It meets the use of most 3D printers.

Features and advantages

• SOC uses Rockchip's 4-core Cortex-A53 architecture RK3328 with Armbian system, perfectly running Klipper host
• MCU uses STM32F407VET6 of Cortex-M4 architecture, 168Mhz main frequency, easy to control various machine actions
• Retain the rich interface resources of MKS PI [with 1GBytes of DDR3 memory, support HDMI screen interface, PI-TS35 screen interface, provide wired Ethernet port, 3-way USB interface (can be externally connected to the main control board, USB wireless network card, USB camera, U disk, USB keyboard and mouse, etc.)]
• Support booting the system from TF card and EMMC module (EMMC module is more stable than TF card, and has faster read and write speed), and provides supporting EMMC burning tools
• Support 7-axis stepper drive to meet the requirements of most 3D printer models
• 3 independent MP1584PEN DC/DC modules provide a strong guarantee for the stable operation of the entire board circuit
• 3-way controllable fans, plus 3-way normally open output, can independently select VIN, 12V or 5V voltage
• Design Schottky diode protection for MOS circuits and temperature measurement circuits
• Design the back EMF energy absorption circuit to protect the stepper driver module
• The Z+ interface can independently set the voltage selection to adapt to different models of PROBE

Download and install system images

Makerbase provides a complete Klipper firmware transplanted based on the Armbian desktop system, and directly supports klipperScreen. Users only need to download the image file provided by Makerbase, burn it to the EMMC module or TF card, without a lot of construction work(If you have purchased a package that includes an EMMC module, the EMMC module has already been burned into the system before leaving the factory, and you do not need to burn it again unless you want to update a new image.).

Hardware Preparation

• An EMMC module or A TF memory card not less than 8G
• TF card reader
• PC with windows operating system installed
• Wireless network card or network cable
• Type_C cable

Software preparation

• System image download link: https://drive.google.com/drive/folders/1tTuSvF9OL2qtPXElau8YOXn2sWbdxa9e?usp=sharing
• Install balenaEtcher v1.5 and above, download link: https://www.balena.io/etcher/
• Install putty, download link: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Flash system files

1. Insert the MKS EMMC module(need an EMMC adapter) or TF card into the card reader, and insert the card reader into the PC
2. Format EMMC module or TF card to FAT32 format before flash system files
3. Unzip the downloaded image file
4. Run balenaEtcher, import the decompressed image file->Select TF card->Click to start flash
   
5. After the flashing is finish, insert the MKS EMMC module to the EMMC interface of MKS SKIPR or insert the TF card into the MKS SKIPR's host TF slot, then power on MKS SKIPR board

MKS SKIPR network connection

Using the Ethernet

Just set your router to using DHCP, plug the network cable into the MKS SKIPR, done.

Using USB WiFi Adapter

MKS SKIPR supports USB WiFi Adapter, but not every type is guaranteed to be available. Now, we the types we have tested available include those based on RTL8188CUS(VID:PID = 0bda:8176)/RTL8188EUS(VID:PID = 0bda:8179)/RTL8188GU(RTL8710B)/(VID:PID = 0x0BDA:0xB711). According to the current testing experience, it is not recommended to use adapters based on RTL8188GU(RTL8710B), it has been supported on MKS SKIPR, but it's driver takes a lot of CPU load(about 27% in our test). Other adapters like the one based on RTL8188CUS/RTL8188EUS have a perfect perfomance. Insert the USB WiFi adapter to one of the 3 usb ports of MKS SKIPR, you have two ways to config it to connect to your router.

Through the config file on the TF card

• Before power on, insert the TF card to the PC with TF card reader, it would generate two disks on PC
• Open the "Boot" disk, find the config file "wpa_supplicant-wlan0.conf" and open it with text editing software (e.g. notepad, notepad++, etc.)
• Modify the ssid and psk according to your router, save the config file
• Remove the TF card from the PC, and insert it to the MKS SKIPR It would connect to your router automatically.

Through the serial software(we using Putty to describe below)

• Prepare putty according to the steps
• On the shell, use the command of "armbian-config" to enter config tool, then choose "network" -> "WIFI” to choose the hotpot to connect to the network.

Get the IP of MKS SKIPR

After connect MKS SKIPR to the network, you can get its IP address in two ways

From the Serial software on PC

Enter the command “sudo ifconfig” and view the IP

From KlipperScreen

If you have a PI-TS35 or HDMI screen connected with MKS SKIPR, it would run KlipperScreen after system boot. You can find your IP address on the "Config"->WiFi

Enter Fluidd interface

After connect the MKS SKIPR to the network, you can directly enter the IP address of MKS SKIPR with your PC's browser, and you can enter fluidd interface(Makerbase's image has installed fluidd, of cause you can install other interface).

Using Serial software on PC(we using Putty to describe below)

Putty is a famous tool, you can use either SSH or Serial to connect to the MKS SKIPR.

• Connect the MKS SKIPR with the TYPE-C cable to the PC, supply power to the PI, check the COM port in the device manager of the PC, and then open Putty
• Select the COM port, set the baud rate to 1500000, and click “Open” to connect

• If you open a black empty window, click the Enter key, and it will ask you to enter the login user and password
• There are two users in the system provided by Makerbase:

  root user: root
  user2: mks
  their origin passwords are the same: makerbase

• After enter the user and password, you can enter the system now.

Config MKS SKIPR's serial parameter on Klipper

On MKS SKIPR, the RK3328 SOC uses the /dev/ttyS0 to connect to the UART1 of STM32F407VET MCU.
On the "printer.cfg" file of Klipper, the serial should be "/dev/ttyS0":
[mcu] serial:/dev/ttyS0

ADXL345 connection and configuration

If you want to use the ADXL345, it is very easy to connect on MKS SKIPR.

The MKS SKIPR image has the acceleration calculation library and the dependent library installed by default, no additional configuration is required, just configure the ADXL345 and test position parameters in the "printer.cfg" file.

1. Configure adxl345 in the configuration file, copy the following parameters to the "printer.cfg" file
   [mcu rpi] serial: /tmp/klipper_host_mcu [adxl345] cs_pin: rpi:None spi_bus: spidev0.2

2. Save and restart Klipper, and send the query command after the web interface does not report an error：
   ACCELEROMETER_QUERY

Now the acceleration sensor data can be received. The data is similar to the following:
Recv: // adxl345 values (x, y, z): 430.619210, 831.432400, 8718.156800...

3. Configure the test position of adxl345, generally installed in the middle of the platform
   [resonance_tester] accel_chip: adxl345 probe_points: 115, 115, 20 # an example

4. Test acceleration and configure input_shaper data
   Before the test, first increase the acceleration configuration of the printer (you can change it to a smaller value after the test):
   [printer] max_accel: 7000 max_accel_to_decel: 7000

5. If there is an input_shaper function parameter in the configuration file, you need to send an instruction to turn it off:
   SET_INPUT_SHAPER SHAPER_FREQ_X=0 SHAPER_FREQ_Y=0

6. Then send the auto test configuration command to start testing the vibration:
   SHAPER_CALIBRATE

7. After the test, it will return the recommended configuration method and configuration value of the x-axis and y-axis, configure the value in the configuration file, then save and restart, the configuration is similar to the following:
   [input_shaper] shaper_type_x = 3hump_ei shaper_freq_x = 52.4 shaper_type_y = 2hump_ei shaper_freq_y = 37.5

USB camera connection and configuration

The default image of MKS SKIPR has already installed MJPG-Streamer and enable the USB camera. MKS SKIPR supports most of the commonly used USB cameras(but not guaranteed). Normally, just connect your USB camera to one of B-Type USB port on MKS SKIPR, you will see the preview video on the Fluidd interface.
If you don't want to use the USB camera, you had better to disable it to reduce CPU load:
Enter the setting item on the Fluidd interface -> camera -> default -> disable

Use with the tool header modules

Support using SKIPR with the tool header modules like MKS THR36/42, more details refer to : https://github.com/makerbase-mks/MKS-THR36-THR42-UTC

'MCU': Unable to connect after power cycle

Hi, until this morning I was more than satisfied with the board. Before that I had a SKR 1.4 Turbo board with a Pi4B. In the last few days I have converted everything to the SKIPR and have already started calibrating the printer, as I have also made a couple of other upgrades. Everything was going great until yesterday, then I switched off the printer and wanted to continue working on the calibration today.... but unfortunately the printer no longer works. After switching on, Klipper no longer sees the MCU.:

mcu 'mcu': Unable to connect
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer

Nothing changed in the config during the night.
Nevertheless, I checked these and the path is still:

[mcu]
serial: /dev/ttyS0
restart_method: command

My first try was a different SD card for the MCU, the second with the mks_skipr.bin from MKS Github and the third with my own bin with make menuconfig... None of that worked.
To me it looks like some defect. If so, that was my first and last MKS board, I have 3 other printers with SKRs and have never had a broken board. But maybe someone here has an idea I didn't think of.

The clipper log says:

TMC2209 wiring for use UART and sensorless homing ?

Hello, I hope you can help me.
Which pins from the TMC2209 v1.3 need to be connected to which pin on the board?
I would like to use the drivers in uart mode.
And use sensorless homing.

Dead Board?

Hi, I have a very annoying issue with this board.

Initially, it worked, copied my printer.cfg across and updated everything and all seemed good until I restarted the board and nothing.

Read through the small amount of info online and found out i shouldn't have updated. As I own a second board for another machine that I bought at the same time with another EMMC module I swapped this in and again everything looked like it was working. I did nothing to the configuration this time and no updates just switched the machine off again and decided to download the latest firmware and flash it to the original EMMC.

After flashing and re-installing the machine just sits there with the LEDs on and does nothing. Switched it off again after a good while and tried the working EMMC module and this time it didn't work and just sat there with the LEDs on doing nothing.

Any help would be appreciated.

The boards were purchased in January so not exactly old and this is the first chance I have had to try them.

Neo pixel stealth burner lights not working

MCU instructions

I've just received an unit and cannot figure out how to use/flash the mcu.

Flashed latest image to the emmc, connected +12v to input and booted the board, fluid gets up but cannot get info from moonraker.
I would bet that the mcu has already been flashed at factory but tried Kiauh build and flash (when asked i'm not sure if comm interface is serial, can or usb can), nevertheless when it builds the firmware it cannot be flashed to /dev/ttyS0, error 255.

Been looking around and while the docs cover the most inmediate operations, cannot find any information on mcu managment, some guidance would be very helpfull, not sure if I'm doing it completely wrong or my board has a defective mcu.

Power loss detect

Is there a power loss detect location on the skipr? I wanted to add a UPS and PWC.

Wifi

I can't connect to wifi. I use several adapters: COMFAST CF-WU815N; MERCUSYS MW150US; noname on MT7601U; noname on RTL8188FTV. And none of them work on skipr, but on my home pc with manjaro each work correctly. What should i do?

Cant reach the board over WiFi

Hi,
I've been trying to solve a problem since yesterday.
The connection works perfectly with a LAN cable, but the attempt to connect to the WIFI fails.
Only if I enter the command "sudo dhclient -v" via (LAN)SSH does the board find the IP that I have already set in the router for the WiFi connection.
Unfortunately, even then I can't connect properly, when I enter the IP, the Mainsail interface shows the window "Connecting to 192...", alternating with "initializing" but unfortunately it never works beyond this window.
I can then also connect via WiFi through SSH, but unfortunately with errors, as if I had no access to the storage space. Can't make updates aso.

What ive tried:

• configured "wpa_supplicant-wlan0.conf"
• added "timeout 5" to the "dhcpcd.conf"
• edited "/etc/network/interfaces"
• edited "/etc/netplan/50-cloud-init.yaml"
• edited "/etc/network/interfaces.d/wlan0"
• installed realtek drivers
• tried system on EMMC and on SDCard system

I don't know what to try next. I don't want to leave the printer connected to the LAN cable because I would have to leave a 10m long cable halfway through the room.
I'm using the "comfast cf-wu810n" WiFi Stick that comes with the board.

EDIT for more informations:

Before i "sudo dhclient -v" i get this when i try "ip a":

Can't invert endstop status using Klipper

I just bought a MKS SKIPR and installed the Klipper on that, but I have a issue when I try to invert the endstop status.
I using the TMC2209 via UART.
I already set (p. ex.) [stepper_x] endstop_pin: PA14 and !PA14 and no effects abut the status, always I get the same.
Looking in Klipper documentation, the ! is the just thing must be changed to invert the sensor status.
Anyone has a clue abut that?
Thanks in advance.

CAN BUS skipr

Hello. I got into the hands of mks skipr. I am engaged in the manufacture of printers and I am looking for a good fee for myself. Mks skipr, good compact board, productive board. But I need it to work completely, help me set it up and I'm ready to buy them in large quantities!!! The essence of the problem: can bus does not work normally. It was possible to connect external boards via the can connector only if you connect the MCU to the HOST via an external USB cable, but this is not convenient and there are no free usb. How to make everything work normally? I did it according to your instructions on your website.

When I home an axis the motor moves until the endstop (mechanical endstop) is triggered, bumps back, axis X and Y is ok, but in axis Z the motor doesn't stop moving in the direction of the endstop.

MAX31865

hello!,

I need help with the configuration for MAX31865, I can't get it to work correctly :c. I need to work using the Z4 spi.

Any One have diagram for MKS SKIPR V1.0?

any one have diagram for mks skipr v1.0 i want know Where can i get this part? it broke 2 item

please replay me
thank you
best reguard

USB Host power

Hi,

is it possible to power the "Pi" part of the board with the USB Host port when no power in main power connector ? Thanks

mcu shutdown overload

Durinig printing i receiving "MCU 'mcu' shutdown. Timer too close This often indicates the host computer is overloaded". printer during stantby mem 87%. camera is connected it and no work. use ethernet net connection

CANBUS

How can I activate and use the CANBUS, otherwise the MKS Skipr is not usable for me?

Bom file

Hello, Is it possible to share the bom of parts file ?

Can i connect and configure the MKS-PWC V2.0?

not connected to wifi. need to manually connect on each boot

I need to manually connect to wifi on each boot. entering pasword on mks Pi display. Is there any way to make skipr save wifi settings and connect to wifi automatically?

list of issues

EMMC not getting detected on 2 TF card readers tried with 2 different adaptors and two EMMCs, TF card readers read other TF cards without problems

ADC out of range on first boot, with nothing connected to board
Internal error during connect: bad marshal data (tuple size out of range) - on second boot
Not getting detected when connected to LAN via cable. Ping to displayed IP - fail
MKS pi screen lags like crasy, hardly ever detects touches - unusable
When connected to any of USB ports, board not getting powered
Same on second skipr board

Rotate screen

I'm put MKS SKIPR with PI-TS35 in to Sapphire PRO printer but screen on PI-TS35 is upside down. It is possible to rotate the screen 180 °.

LCD Rotate

Hello, maybe someone can help me how I can rotate the display that is connected to the ribbon cable?

Hallo, vielleicht kann mir jemand helfen wie ich das Display was mit dem Falchbandkabel verbunden ist rotation kann ?

Stepstick Jumpers

where can i find a manual for set stepstick jumpers. on my build i has 2209 for X & Y, 2208 for Z and Z1 and lv8729 for extruder. the tmc´s run on uart and the lv8729 @ 128 steps. i set the jumper analoque to other mks board, can you confirm that i make it right? ;-)

Make CAN interface work properly (Not only CAN-to-USB !!!!)

Currently, only CAN-to-USB communication is possible with the SKIPR board. This really sux, as the board has a CAN connector which is not functional as it seems.
I could get my FLY-SB2040 to work in CAN-to-USB mode, but for that I would not have needed the SKIPR board, this would have worked with any other. You are giving away the selling point for your board. PLEASE DO SOMETHING.
