@@EdwardBraiman i get tmc conenction error , i hope you have 10 or even 5 minuts of your time to help me fix it

First is you system powered by a power supply and not the USB power. Second check to see the are correct TMC stepper driver in video. Third swap steppers if issue persist with other steppers to see if system issues follow. Between steps to power down system.

This videos scope is for SKR v1.3. you will need to read the manual for bigtreetech TMC 2208 as they may require changes. Also there is directions in Marlin firmware you need to follow.

Well you should use the datasheet and equation in the firmware to start, but for testing it's okay.

They should be soldered on bottom if you purchase from bigtreetech, but you can inspect with a camera zoom to check.

@@EdwardBraiman yup got mine from them bundled with the mobo. But the mobo just died a few hours earlier, it turns on but the main chip became a huge resistance lol. But thanks, I will keep that in mind when ordering a new one, I had initially soldered mine like that, bottom wise, but even though the motors were working it would not home for the life of me, that's also something I have to work on.

Sorry, to hear about your motherboard. Do you know what caused the issue?

I would start with default setting after computing RMS and divide the connection using the technique ... kzfaq.info/get/bejne/r9iDhtOkmcC7gZ8.html ... Start as if you're working with one motor. Let me know how it works out.

@@EdwardBraiman All working good at default settings. Sure is quiet with 32 bit board and 2208 drivers.

Yup.

@@EdwardBraiman Thanks a lot Edward!!!

You're welcome.

Check defualt axis steps per unit. The reason I added drv8825 was to show the numbers being changed. So try doubling the number for that axis. Let me know how it goes.

@@EdwardBraiman double the numbers to decrease the distance moved? I thought it would be half? I will try it as soon as I can and will get back to you. Thank you for your speedy reply.

Np

@@EdwardBraiman okay so a little update on my firmware situation... there is nothing wrong with it! I came back to it after a day at work powered it up and all of a sudden everything was moving fine. Not sure why this is as i had done several power cycles already. Either way after following your tutorial my printer now works flawlessly so a Big Thank You!

You're welcome.

The jumper caps in correct position are still required. On underside of TMC steppers there was a quality issue that myself and other early adopter's experienced with zero ohm resistor falling off. Since then it's been mostly corrected.

Are you programming board from Raspberry pi?

@@EdwardBraiman No just running Octoprint. I actually find it easier to pull the sd and upload directly to the sd from Platform IO. Are you thinking I don't have to switch the jumper if I am not programming ? Seems like I tried running Octoprint without switching into program mode and it didn't work at all but I may be wrong.

What happens if you try the way in the tutorial?

Ich hatte eines, das einige Probleme hatte, aber die anderen vier schienen gut zu sein. Anscheinend fehlte ein wenig Lötzinn, aber es war in Ordnung, nachdem ich es mit dem Lötkolben berührt hatte.

Soon.

@@EdwardBraiman Thanks

You're welcome.

There are three modes you can use on tmc2208. I'm only addressing UART mode of stepping in the video. Soldering normally is not required unless there is a defect in manufacturing.

It maybe related to me switching to VScode from ATOM with Platformio plug-in.

Edward Braiman I will look into the above I know more about SKR 1.3 than I did yesterday, if the file structure was fully open I would be able to do all the work required, I think you said for the usb and power supply, you can use both at the same time, presumable you need a jumper to short out all three pins? Thanks Simon

The jumper is only for two pins.

It's for contrast. I'm trying to show people where to adjust steps, so they know later for the TMC.

It may check the datasheet in the summary below video under documents.

This might be a better option. www.trinamic.com/products/integrated-circuits/details/tmc5160/

@@EdwardBraiman Hi do you know if the TMC5160 compatible with SKR v1.3 printer board, I've looked at spec, step driver is not listed?

Sure, but my two week vacation is a couple of weeks away.

Yeah, that would be awesome. I have struggles with my original BTT TMC2209 as well - Did everything as in the Video but the drivers do not register (Testing X connection... Error: All LOW). I did not try it out with the correct voltage from the power supply, only powered by USB - can this be the problem?

@@ThePixelbuilder Have you gotten any further? I seem to be in the same situation you are. BTT TMC2209 v1.2 with BTT SKR v1.3 on all steppers (X, Y, Z, E0) and when just connected to Pronterface via USB, I get the same message you show. Any other sources of help that you have found? I didn't think I had to do anything with the solder pads due to the UART jumpers on the SKR v1.3 board.

Is the PSU connected and powered when I saw low, the power was disconnect. I'm getting ready to do a video on tmc2209 UART maybe today inn SKR 1.4 and maybe tommorow on SKR 1.3.

@@mkirich you the the power supply from the PSU with USB alone it did not work for me.

Depends on you level of experience. As a beginner I recommend starting with drv8825. When you become more confident, then tmc2208. And when you're very experienced, then tmc2130. This is only because as a person gains knowledge they'll understand what's going on.

Originally yes, but they fix most of their quality control issues, so it's not recommended anymore.

They had an issue with zero ohm resistor falling off at least in my case.

Tell me about the hardware you're using?

Edward Braiman It’s for a CoreXY printer and it’s the big tree skr 1.3 and big tree’s tmc2208 to control all 5 steppers (I have daul z). I’m using Marlin bug fix 2.0.x. Also, I don’t know if this is ok, but I’m ejecting the micro sd card from board and putting that in computer and then putting it back in rather than uploading through USB. Also thanks for fast reply :)

Are they TMC 2208 UART Steppers? Can you tell me about your settings in Marlin firmware?

Edward Braiman Dang! I think you may be right, I got the combo from aliexpress and it was the TMC 2208 DIY x5 option instead of the TMC 2208 UART x5 option. I didn’t even realize there was multiple options. So this means I need to order new stepper drivers right?

Well unless you can modify yours to work the same.

Not anymore, they should be in place when you order the steppers.

@@EdwardBraiman thx and good to know. I ordered my board and steppers a while ago and it was a real pain to solder the pads together

Just remember most the time this should not be required. Also soldering can add danger of stepper failure.

@@EdwardBraiman in my case, the drivers did not have the 3 pads joined together

It's called SPI, for serial peripheral interface. It's a hardware configuration with software to communicate via specified hardware address. The reason I don't go into extreme detail is to have some ask for more detail. In the case of the pins file, the pin for a specific stepper like TMC 2130 in a SPI configuration will say move the stepper this amount base of PWM (pulse width modulation). This can also be applied to other device like LCD, data transportation, ECT. Keep in mind I'm trying to teach a simple task for people to maintain interest in 3d print and learn on there own in greater detail. If I spent 45 minutes explain how packets are assembled and transfered over a wire people would become bored. If I start talking about the software protocol development and abandonment by 🍎 corporation. If you would like I can talk in great detail as I've worked on SPI for a number of years professionally? Personally, I want people like yourself to challenge me by challenging yourself to teach others with empathy and encourage learning. Thank you for explaining to me I was not detailed enough, I'll work on it while trying to keep the tutorials fun.

Sorry I water down the tutorial as a way to keep most interested in learning how the printers function. I want to make it look easy to learn.

I'm using the firmware default in the video, otherwise as you noticed it will cause confusion. Great catch, for people in a similar situation as you. The actual values can be dereived from the RepRep calculator on Marlins webpage. Sometimes I'm just trying to hit the main setup points and skip the finer details. I'll try and remember to say something for SKR pro v1.1. currently I'm holding back on those videos until I have several.

@@EdwardBraiman Thanks, totally new at 3D printing but I've been a computer geek since the 80's. Loving that I have a reason and motivation to pull up my old skills for a practical purpose for this toy that makes toys.

It appears to support SPI for TMC2130 at least with the tests I ran. It's tied to the TMC 2130 step stick Bigtreetech produces. It may have issues using other SPI devices at same time. I had issues with it working consistently with USB jumper in 5v position.

I'm thinking about it.

@@EdwardBraiman would love to see you doing the skr v1.3 with tmc2209

It maybe nessary depends on you configuration. If you're upgrading and direction changes yes. If you building initially then you may plan for it.

@@EdwardBraiman thnx Edward

@@EdwardBraiman is my assumption correct, for the UART use (with SRK v1.3 or v1.4 boards) Vref Max on TMC2208 doesn't have to be set per potentiometer

Yes.

@@EdwardBraiman thnx

I just did x and y, because I was reenforcing how to set it up without making the video too long.

I've not tried to, but should be possible.

I do not have the Big tree Tech drivers.

Well you'll need to check the datasheet for UART configuration on those steppers. It should not be that difficult. They explain which solder pads are required. Let me know how it turns out.

The board can do CNC as for machine types unsure, but anything is possible.

@@EdwardBraiman I believe it can, CNC is not much different than a 3d printer. The printer lacks an analog for the spindle and all inputs and outputs need isolated, but that is not hard to do. I just got one in and will be attempting to use on a CNC router that I am building. I will let you know how that goes.

Not sure I understand, the video is for tmc2208. Could clarify?

Okay I think I understand you're saying to do TMC 2209 you'll need to add a jumper. Good to know.

@@EdwardBraiman a) I still have a cashed copy that labels TMC2209, guess there was a typo when uploading? b) the communication problem may not just be for 2209. 2208 and 2209 communication is rather identical. It's the problem that the pinout of the step sticks seems to be not standardised. My 2209 are FYSETC v2.1 and you recognise the variant with seperate Rx/Tx pins, the pin sequence is EN, MS1, MS2, TX, RX, CLK . There seems to be an 1kOhm between Rx and Tx pin and only the Rx connects directly to the TMC chip. This sticks obviously have an integrated Rx/Tx sepearation circuit that conflickts with the BigTree layout. This separation circuit is already on the SKR layout when you check their shematic. Otherwise you get level problems between Rx and Tx on the micro controller ports because of the added 1kOhm on the stick. So the SKR1.3 connects the UART jumper to the sticks TX pin only, but expect a single UART pin going directly to the TMC pin on the step stick and do the Rx/Tx break out with the 1kOhm in the SKR board layout. By the additional jumper I can fix this and bypass the 1kOhm on the step stick between Rx/Tx and the SKR gets access directly to the TMC chip pin. So I spare myself the modification on the step stick with solder irron and tiny surface mounted components. Just wanted to note, that you need to be carefully with step stick VARIANTS out there. That's because the step sticks aren't standardized for the Rx/Tx pinout and you may get similar problems with random 2208 sticks as well as some 2209. There is no guarantee that they do it as Bigtree expects it. I think Bigtree takes this in consideration on their step own step sticks, but when using random cheep chinese supplies you can have the same UART problem with any 2208/2209 clone sticks.

@@EdwardBraiman He's referring to the title of the video. You wrote "SKR 1.3 - TMC2209 UART v3.0" instead of "SKR 1.3 - TMC2208 UART v3.0"

Should be done electronically.

I've only done 1 board with Marlin2.... the board does not connect to platformio. Its the suite you use to edit & compile the firmware. Then you copy the file over to your SD card. With the printer off insert the card then power on. The firmware will "auto install" to the printer. Tim at TH3Dstudios did a good demo/walk thru of this with his EZLite board.

Watch "TF drive Marlin firmware loading"... on this channel

I'm researching Raspberry pi printers, but Klipper documentation is very sparce.

There different, but similar. I like them both.

Check the examples folders for Marlin firmware, they may have what you need.

@@EdwardBraiman I have LPC1768 failed error all the time. Can you help me with this ?

Three things come to mind, configuration.h motherboard, serial port. Platformio.ini, Default environment is LPC1768. Also try doing a fresh unzipped build with default configuration. Also make sure your computer is connected to internet while building/compiling to pull need files. Hope this helps

@@EdwardBraiman I connected skr1.3 with Ender 5 but showing me TMC CONNECTION ERROR info on the screen . I can move axis but problem is I thin k with Extruder stepper.

Bigtreetech finally processed my order for tmc2209, today. I've been trying to aquire for months.

Oh my, lucky you!

Third try is a charm.

First does a defualt folder project build okay? What I'm saying is open a fresh download that has been unzipped and click check mark in platformio inside ATOM.

If it's not working checkout the instructions on how to install ATOM with Platformio instructions on marlinfw.org. You may also need to install Git to make it work from ATOM.

Got it fixed! Not sure how, but in case someone has the same issue.....? Pulled the microSD and put it in a card reader. Showed the original cursor file along with the BIN. However, the BIN was showing a size of 0. deleted the file then used Atom again to upload the build but left the microSD inserted through the card reader. New BIN showed up. Plugged it back into the board, then the USB into the machine, and BINGO. It worked. Not sure what happened the first time but we're good to go now!

If it makes you feel any better, the same issue occured for me until I realized the operating system takes a moment to recognize device again. Also, I've made the mistake of not specifying, "#define serial_1 -1" several times.

Well, I appreciate the video. It helped this NOOB. Now I just have to get my ABL set up, everything wired, and I should be good to go!

Check the solder joints on the steppers. Sometimes this have a weak joint or check the jumpers. Also try moving steppers to see if problem moves. Try swapping E and Z first.

Forget about it, I just solved it! It needs to be connected to a decent powersupply, as the 5V USB connection does't seem to suffice. After hours of tinkering it now works :)

Good to know. I had many problems trying to get the tutorial as usable as possible. Thanks for the update. I'll be doing SPI tonight and it was difficult to make as clear as possible. I'm planning to explain RMS in another tutorial, just needed to find a way to explain for as many people as possible.

Alright, copied a firmware.bin directly to disc and restarted and it came up.

Platformio will handle files for LCD.

I'd update, but not sure board is sold anymore.

If you're seeing what you think is a Marlin firmware error, you might want to open a bug on Marlin Git page.

Are you using ATOM/platformio plug-in? You may want to change to VScode as it will work better. I know some of my tutorials have ATOM, but I've changed due to support of platformio being discontinued. There is a SKR 1.4 tutorial where I explain install.

It's on advanced tab changing number 16 to 32 or 64 or 128 or 256.

If you're using platformio, do you have Git loaded? What's the error message?

The drv8825, was tuned before video.

Is this a fresh download? I'm unsure of the issue other than something with chip select, which is normally used in SPI. If you download a fresh copy of Marlin firmware and see it again I suggest opening a bug on Marlin firmware GitHub page.

yeah, it's a fresh download from yesterday, from a file that was last uploaded 18 days ago to the git hub site here.. github.com/bigtreetech/BIGTREETECH-SKR-V1.3/tree/master/BTT%20SKR%20V1.3/firmware/Marlin-bugfix-2.0.x/Marlin/src/feature/touch Guess I shall open a bug on the page.
