Thermosters Not Working

Plug in thermistors and they read temperature as 0.0 degrees celcius despite correct settings in marlin 2.0. Potentially a short in my board circuitry as not connected to printer yes as still trying to get temperature readings to work. Not even dummy thermistor settings in marlin work on it.

Bootloader for LPC1768

Where can I get and how to install the initial bootloader for the newly soldered LPC1768 ?

[BUG] No TMC2208 connection on SKR v1.3

Description

After removing the jumpers under the Steppers and inserting the UART jumper, TMC2208 is still recognized as "ALL LOW"

Steps to Reproduce

1: Get TMC2208
2: Solder bridge for UART to PDM pin
3: remove jumper between stepper pins on the SKR1.3 board (not sure about that)
4: insert jumper on UART pins for axis
5: insert stepper driver
6: boot up (assuming all configuration in FW is set)

Expected behavior: [What you expect to happen]
UART Connection made

Actual behavior: [What actually happens]
UART Connection ALL LOW

Additional Information

FW Configuration:
@platformio.ini: env_default = LPC1768

Adc pin? For use with zonestar lcd buttons

I have a zonestar LCD controller and have modified the connector so the LCD section functions well. The trouble is when I try to define the adc hardware buttons to the suggested pin (beeper p1_30) in marlin, the skr boots then proceeds to crash are restart.
I know this LCD has been adapted to other boards, but the pins are obviously not similar when it comes to buttons.

Is there a pin free ( maybe from servo port P2_0) that I can use to handle the adc?

Sorry im new to posting here so if any code or files are needed im willing to provide what I have.

SKR v1.3 PS_ON Pin

I am building my own 3d printer, it is a delta printer so I decided to go for a 32-bit board. After some research, I concluded that the SKR 1.3 was the best option. With only one problem. I want to use an ATX power supply but can't find a PS_ON# pin on the SKR 1.3. Is there any way I can assign a PS_ON# pin or cant this board do this? Thanks for the help in advance.

NO MacOS support ??

So I was happy to receive my SKR 1.3 only to realise that there is little or no support for Mac OS. I know the firmware is based on Marlin 2.0x but disappointed to see little or no activity in responding to issues raised her on github. I have tried to use both the original BigTreeTech firmware and also the latest Marlin 2.0 release - flashing it to the board / SD card. I have had very little success in communicating with the board via USB cable (from my Mac) also octopi will not connect or communicate with the board. I am hoping that BigTreeTech will respond to the issues raised her on GitHub very soon

Board does not boot anymore

Hello !

Everything went fine with my new skr 1.3 ( Marlin 2.X ( Ender 5 ) for about 20 prints.
Suddenly when i start my printer i get a constant beep tone and
a blue screen ( Stock Creality screen).
So i disconnected everything switched to 5v jumper and tried to recompile the firmware as usual via PlatformIO.
I get the error "board not found". ( But it shows up normally under windows 7 )

• Already tried another sd card, same problem.
• checked fuses
• pushed reset button , nothing happens, red Led is on all the time.

I am thankful for every hint, thank you in Advance !

Analog or digital pins

I have the BIGTREETECH-SKR-V1.3 and would like to control some RGB LED lights from it on the printer. I'm looking at Thomas Sanladerer setup on YouTube. But i cant see any Analog or digital pins on this board. can i use the End Stop+ pins if so how any help please.

How can I use it with SKR + smoothiware?

DRV8825 loaded but wont move steppers

I just received the board, installed the firmware, installed correct pins and installed DVR8825 drivers but I get no movement from the stepper motors, not even a slight resistance when turned by hand. I set voltage 0.8 the driver chips are getting hot just don't seem to be working. I rechecked firmware 4 times using atom firmware compiled and uploaded just fine. I'm

<script src="https://gist.github.com/daimein2007/bda8392cc5c4be8bdeb42da9806ed9b0.js"></script>

stumped.

Smoothieware not changing ports after defining.

I have been working on getting this board to work on a K40 laser. When I define the #laser_module_pin to 2.4 . The firmware doesn't seem to respond. When it is commanded to fire through software, the 2.3 mosfet led lights up. So I tried 3 times with 2 different boards (which I may add both ended up breaking) to change the pwm pin . Now through what I have read there is alot of pins that can be used for this function. But without the board doing what it is told it is useless. So I am at a loss. Is there a dev that can help me. I was going to post this setup on several sites to promote it. So please lend a hand!

[BUG] M190 ignored (critical)

The following defect was described in the Marlin 2.0.x build that this one is built from (note link below):

MarlinFirmware/Marlin#13287

The gcode M190 is used to make the gcode wait until the bed has reached the correct temperature. However, in this build, M190 is ignored, so the nozzle and heat bed begin heating at the same time. This can increase the draw on the power supply to above specifications (in my instance, the main fuse on the power switch blew at 4A).

I tested the issue by forcing M190 in the gcode and noticed that both tools began heating concurrently. That's when I found the defect had been documented in the main branch. I assume that this branch came before this defect was addressed.

I believe this is a potentially critical bug because it can cause damage to hardware.

Poor SUPPORT and response to issues

Very disappointed to see NO UPDATES to what really should be a Production board - NOT alpha release. Yes there are reports about the board up and running fine (good) but to far and few in-between. NOT GOOD enough - 3 months sine last update ?????

Stepper driver diag0 and diag1 pins missing connectors.

In your SKR v1.3 youtube video there are female header pins for TMC2130 diag0 and diag1. On your aliexpress and github pages none of the diagrams show a connector for those two pins for each driver for sensorless end stops. Are they present on the production boards you are selling or not? If not will they work if I connect them?

Board doesn't boot after firmware install

I've compiled and installed a known working Marlin 2.0 firmware and everything works great.

I made my own Marlin 2.0 firmware for my custom printer and the SD card immediately doesn't work again. Try the other one and it works.

I thought I was smart so I edited the working firmware and again it doesn't work.

Here are my configs if anyone wants to take a peak: https://drive.google.com/open?id=12n-i3yIjOXyX-WQ-DNjE4RwaVvA7YZh3

Not sure what's up but I'v never had this issue with the MKS Gen L

1.3 hangs / crashes

Hi, I installed the 1.3 version over the 1.1 I used until now. The first minutes all goes well but after some minutes the card hangs ( display non responsive, and movement stops). In another crash it was, instead of continuing on the y axis, busy doing endless repeating moves, forward / backwards etc. After I put back 1.1, all went back to normal. Can it be a new config setting? I checked thorougly and like I said, the first minutes all goes well. The files are correct and were never a problem. Stepper drivers where 60°C and the nema's 23°C , thus way off the limits. More people having this issue?

Smoothieware+TFT35 source code not available

I noticed there is source code for Marlin (https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3/tree/master/firmware/Marlin-bugfix-2.0.x), but there is no source code for Smoothieware+TFT35 (https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3/tree/master/firmware/smoothieware%2BTFT35). Just binary firmware.bin is available.

As this code is based on the open source Smoothieware code (https://github.com/Smoothieware/Smoothieware) and Smoothieware is using GNU General Public License v3.0, you have to follow and open your source code with all the needed modifications and additions (board customizations, TFT35 communication, etc.)

5V UART are tolerant?

I use OctoPI and conect it to my board with USB TTL converter CP2102. Converter has 5v ttl logic level. Can I conected it to TFT or AUX-1 plug? Should I look for a converter with a 3.3V ttl level or I can use an existing one.

smoothieware does support Linux

Sorry, but this sentence in the instructions for the SKR 1.3 makes no sense:

Note: When using smoothieware open-source firmware, since only Windows system
drivers, the SKR board at this time can only be recognized by the Windows system
port! ! !

If you didn't find Linux driver, then you searched for them at the wrong place. Linux has drivers for all known USB to seriell drivers already builtin. Currently I don't own a SKR 1.3 board, but I use the MKS Sbase with smoothieware with Linux without problems. The SKR and the Sbase are very similar, at least they use the same CPU.

Linux supports all this boards for 3d printers much better than Windows. No installation of drivers necessary. It is really Plug & Play.

Erase the memory of the SKR 1.3 board

How can I erase the memory of the SKR 1.3 board?
I can not upload again a new version of the firmware I have installed, it always stays the same.
In an arduino board is with a script, in this I do not know how to do it.

BLTOUCH configuration issue

I've followed the instruction of this video to configure my BLTOUCH sensor:

https://youtu.be/oaXfXkPYHpw?t=244

But that seems to be outdated, the video says to uncomment this line :
#define BLTOUCH
and then comment this one:
\\#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
But after that it says to uncomment this line, that no longer exists:
#define Z_MIN_PROBE_ENDSTOP
I've tried skipping this step but as results my BLTouch doesn't work and stay blinking with red lights.
I'm missing something?, I've checked the pin connections and everything seems to be ok

Alternative option If you came here looking for help

BigTreeTech's video's and configs are already far out of date due to rapid changes in Marlin bugfix2.0 branch.

BigTreeTech hasn't really kept up well with responding to issues here, and creating Pull Requests could mess up their product delivery approach.

I've spent a TON of time getting familiar with the issues related to this, and I'm familiar enough with Marlin to help most of you get up and running regardless of your printer model.

If you came here looking for help but can't get an answer, I invite you to drop into the HackerHappyHour discord 3D-printing channel to ask your questions, and I will do my best to help get you up and running.

Another alternative you have, is by checking out my up to date configurations for the SKR v1.3. I'm sharing two links with you. one link will be to the auto-updating tip of my configuration branch, and the other will be a "compare" link that will show you what is different between my configs and Marlin's default configuration files.

The first link is going to be treated as a "production" branch, so you should consider it stable. Please note however, that I have an ender3, and the configs are related to that machine. You can use the second link in turn to see what changes I made so you know what items to look for and modify based on your printers specifications.

I will plan on pulling in the latest Marlin firmware once a week, and both of the links below will reflect those changes... so feel free to bookmark them without fear.

Marlin 2.0 - Ender 3 - SKR v1.3 config branch: https://github.com/HackerHappyHour/Marlin/tree/ender3-skr-v1.3-config
Comparison between my configs and latest Marlin 2 default configs: MarlinFirmware/Marlin@bugfix-2.0.x...HackerHappyHour:ender3-skr-v1.3-config

I've also tried my best to make my commits for this branch tell a story, or as a documentation of sorts. You can read the commit history using the compare link above, or using this link.

For those of you not familiar with git, any commit that has a ... icon next to it means there are more details in the extended commit message. I geared these as comments for you guys, to explain why I did what I did. Click the ...'s to uncover those comments.

Header pins (SPI and UART)

@bigtreetech, Please,
In next version of this board, provide a header pins with all SPI/UART pin available to use with a header cable.

E.g. I only use SPI in X and Y and don't use UART mode, but I need more pins to configure my hardware, and with a better location on hardware. Like the AUX-2 of GEN L

So. We will have a 10 pins to use:
#define X_SERIAL_TX_PIN P4_29
#define X_SERIAL_RX_PIN P1_17 < Same as CSX
#define Y_SERIAL_TX_PIN P1_16
#define Y_SERIAL_RX_PIN P1_15 < Same as CSY
#define Z_SERIAL_TX_PIN P1_14
#define Z_SERIAL_RX_PIN P1_10 < Same as CSZ
#define E0_SERIAL_TX_PIN P1_09
#define E0_SERIAL_RX_PIN P1_08 < Same as CSE0
#define E1_SERIAL_TX_PIN P1_04
#define E1_SERIAL_RX_PIN P1_01 < Same as CSE1

Thank you

[BUG] BL Touch doesn't work with "#define FAST_PWM_FAN" enabled on BIGTREETECH SKR V1.3

Description
If I activate "#define FAST_PWM_FAN" in your most recent version of Marlin 2.0 my BL Touch Probe stops working connected to my Board " BIGTREETECH SKR V1.3". The Probe shows blue LED always on and doesn't react to GCODE.
If i uncomment that line again everything works fine.

Activate "#define FAST_PWM_FAN"
Use the hardware mentioned above
Expected behavior:
Fan should be silent if running on reduced Speed AND BL Touch should still work

Actual behavior:
Fans are silent, but BL Touch stops working.

Why is the Z_probe pin the same as the X min endstop?

Dual Extruder pins

Hello,

I wanted to have more details about having dual extruder on the board, in particular the pins layout and also the temperature pin.
Any information?
thx

Had some intermittent issue with uploading firmware from sd card. Now the board does not read anything from card and over usb is not recognized.
Help please

SKR 1.3 with MKS2208 v1.1 TMC Connection Error (UART)

I got my board today. For testing, i connected one stepper (Z). according to the manual i removed all jumpers from the STEP/DIR headers and set them on the UART headers. But i always get a TMC CONNECTION ERROR on the display...

This is may current build:

BIGTREETECH TMC2208 UART dosnt work with Linear Advance

I bought SKR 1.3 and TMC2208 UART all from BIGTREETECH and all seem to work fine with Marlin Fix 2.0.x

The only issue that the extruder wont rotate unless I disable Linear Advance in marlin. I had to disable it to make it to work which is frustrating I need that option on and cant find anyway to make it to work.

#error "X_MIN_PIN is not an INTERRUPT capable pin."

Can someone help me with this error?

Sensorless Homing not triggering

I am using the original TMC2130 drivers in my board. I have all the required modifications made to my firmware. I even went as far as swapping out, inverted and non inverter endstops just to see. I have tested on the board with a multimeter the diag 1 pint to the endstop to make sure that there is a connection. Also missing from the outstanding video made for showing all of us how to setup this board, Shutting off homing bump from 5 to 0 . But all my attempts to get sensorless homing to work has gone without success. Is there anything else I could check?

TMC Connection Error

lcd shows TMC CONNECTION ERROR , and if i send m122 i get all low on xyz and e.

i have soldered the j2 pads, set TMC2208 , set both serial ports as shown in the instructions in config, set tmcdebug in config adv.
I have all jumpers removed except the uart jumpers.

is there something im missing?

TMC2208 [TMC CONNECTION ERROR]

I configured marlin and SKR1.3 to work in uart mode but i have the same message on the display.
The driver are BIGTREETECH TMC2208 SKU:UUU001758
The board is SKR V1.3, i follow the instruction here: https://www.youtube.com/watch?v=oaXfXkPYHpw
But i have the same message on display.

Attached a photo of my driver.

TMC2130-SPI with wire

How can I connect TMC2130-SPI with wire to SKR v1.3 like v1.1

TMC2208 X connection... Error: All LOW

TMC2208 X connection... Error: All LOW

But same Stepper will work in Y,Z or E. So Stepper ok.

X will work with TMC2130 in SPI mode or TMC in Standalone mode. Think it may be the X-UART jumper pins ?. How can i test. Have 12V and USB to Raspberry PI plugged in and powerd up ok.

BigTreeTech SKR board.stl is wrong

BigTreeTech SKR board.stl is wrong the outer connector of the stepper driver is 2.4mm too far in.
The two big connectors are (heatbed and 24Vin) are 1.3mm to wide
TH1 TH0 TB are 1.3mm too far to the right and should be touching AUX-1 and should be 23.9mm wide not 22.7mm.

USB Port is 1mm to narrow

Problems installing driver (Windows 10)

I'm happy to say my SKR v1.3 arrived today. So far it hasn't been smooth sailing unfortunately.
One of the things i'm stuck at is installing the drivers to control it with Repetier for example.

I get the following error when installing lpc176x_usb_driver.inf
"The folder you specified doesn't contain a compatible software driver for your device If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems. "

What can i do about this?

Max voltage for ABL and auto power pin?

Hello,
I was looking under the pin group and I didn't see a pin specific for "auto power off after print", I am assuming that PS_ON_PIN?

I am using an inductive z probe and I wanted to know the max voltage the Z-min pin can handle?

Thanks!

((TMC connection Error))

Dear Friends ,
Since 2 week i work on SKR 1.3 with BLTouach and TFT SKR.
and i have The Original TMC 2130 from WATTEROTT .
when i configured the board with Marlin-bugfix-2.0.x .
i have always ((TMC connection Error)) on / display 12864/,
and on Pronterface With (( M122 Code)) i have:

my mode is: TMC 2130 /SPI Mode/Sensor less homing for X and Y BLTouch.
Of course, i changed the processor name to(LPC1768) and motherboard name to (BOARD_BIGTREE_SKR_V1_3)

So I need your help and suggestions Please

Pronterface won’t connect to the skr v1.3 after updating TFT35 with new firmware.

I’ve been working and testing the new skr v1.3 with TFT35 v1.2.6 on pronterface. I updated the TFT to v1.2.11 and then tried to connect to pronterface. I’m not able to connect. Pronterface just says connecting then times out. I changed the TFT35 firmware to v1.2.10 from here and the same results. I deleted the firmware that came with the TFT.

Is there a way to make the skr board visible to pronterface again? This TFT firmware is a brand new beast to me.

ESP3D - where to connect?

Is there any other usable UART besides TFT/AUX-1? I need to connect ESP3D and my TFT/AUX-1 is already used by TFT35.

Missing license on the repository

Hi,

Thanks a lot for all your work, very nice to see a Chinese company make so much progress toward opensource (especially sending PR to Marlin for TMC2190, nice work!).

I was wondering what was the license of this repository? Can a LICENSE file be added to the top of the directory at it is custom for github?

Thermocouple board connection

To which pins do i need to connect thermocouple boards and do i need to set other settings in the firmware except the ones below?

• -4 : thermocouple with AD8495
• -3 : thermocouple with MAX31855 (only for sensor 0)
• -2 : thermocouple with MAX6675 (only for sensor 0)
• -1 : thermocouple with AD595

Some pictures with the contacts to be used marked on the board would be nice.

Reset button dosent reset board

Reset button does not reset my board and thermistor pins don't detect temperatures just read 0.0.
