TMC 2208 on Fystec F6, Unable to read register IFCNT

[szaghi]

Hi all,

thank you very much for your great work, it is really appreciated.

I am not able to make working my new Fysetc F6 board with TMC2208 in UART mode, please see below my klippy log.

I have tried to dig deeper my self reading older issues, but I have not understand what I am doing wrong. The only doubt I have (and not yet able to test is) is related to the board powering, I have connected it only to the raspberry via USB without 12V PSU supply. Is the PSU powering relevant for driver register reading?

I am a newbie (although @SimoneBnc is kindly trying to help me) thus surely I am doing some very silly mistake.

Thank you for any hints and apologize my self if this was a well known issue.

Hi Simo, yes, I hope so, I followed your last video where the guy suggest to solder the 3 pads near the chip, I having the Fystec TMC2208 v1.2 with 3 pads instead of 2. The jumper configuration should be right, I have shorted the 2 left pin below the drivers.

[klipper-gitissuebot]

Hi @szaghi,

It did not look like there was a Klipper log file attached to this ticket. The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions).

Unfortunately, too many people have opened tickets without providing the log. That consumes developer time; time that would be better spent enhancing the software. If this ticket references an event that has occurred while running the software then the Klipper log must be attached to this ticket. Otherwise, this ticket will be automatically closed in a few days.

For information on obtaining the Klipper log file see: https://github.com/KevinOConnor/klipper/blob/master/docs/Contact.md

The log can still be attached to this ticket - just add a comment and attach the log to that comment.

Best regards,

@szaghi
i am not sure but the logfile looks incomplete to me.

[szaghi]

Hi @Stephan3 let me know what I have to do to create a complete log, I have just followed the indication to do a M112 command after I saw the unable to read... issue

[FHeilmann]

I'm not familiar enough with the tmc2208 in particular. But in case you haven't considered it, think about that the communication with your drivers might not be working at all and the "IFCNT" register is simply the first one that fails to be read.

-Florian

[szaghi]

Hi @FHeilmann thank you very much for your insight. In case the communication is not working at all what do you suggest? What can I do for checking? I have some LV8729 drivers

[Stephan3]

@szaghi did you solder the pad on the buttom? show us a picture.

[szaghi]

@Stephan3 yes, maybe my soldering skill is the problem... here is my very bad pond bridge

[Stephan3]

@szaghi Ia ma not Sure about those clones as i use usaly watterotts. Regarding to this you did the soldering wrong?

[szaghi]

@Stephan3 this is an open question for me. For now, I followed what is stated here

It seems to me that for the 3 pads version (v1.2) I have short all 3 pads, maybe tomorrow I can try shorting only the 2 upper, if it is what you are suggesting.

[KevinOConnor]

Is the PSU powering relevant for driver register reading?

Yes. In all common configurations, the TMC drivers are powered from "motor power". So, if the external power supply is not enabled then one will not be able to communicate with the drivers. Be sure to bring up the external power supply first, then issue a RESTART command to have Klipper initialize the drivers.

@KevinOConnor

OMG, I am very sorry my lazyness, I had to test it with PSU power immediately, I hope to be able to check it later today (hoping that my soldering is not a totally lost of time). Thank you very much Kevin.

[JamieAKing]

Good new ...The soldering looks good (by good I mean the same as mine,) so the chip should communicate with Klipper.
Bad news .... I have the same board and drivers and have had very limited success.
I hope you have better luck than I’m having, if you do could I ask that you post your stepper configs so that I may compare.

Steps taken so far....
Z is working. I had to set interpolation to false and micro to 16. I also followed the steps in issue #196 to setup auto_grad and stealthchop threshold
Extruder now working as I type this but only after the above is done AND stealthchop is disabled (set to 0), noisier but not drv8825 noisy. I have tried a silly high stealthchop_threshold 100000 in case the pressure advance movements were the culprit of very small very fast direction changes but still receive low side short A
I have yet to find a xy configuration that is reliable.
Patience is at an all time low and I’m currently awaiting some 2130s to replace the drv8825 that are currently running the XY
Hope this helps a little
Best of luck
Regards
Jamie

[szaghi]

Hi Jamie, thank you very much for your insight. Maybe tomorrow I'll be able to power on the board (the printer is busy, I have to stop printing for a while to power the F6). Anyhow I am really a newbie regarding stepper configuration, I am simply following Simone that had success in using tmc2208+f6+klipper.

I'll post my progress here, I hope tomorrow.

Cheers

[Mamath2000]

Hi friend,
yes : TMC2208+f6+klipper, it works like a charme since at least 6 mounth.
how have you configure jumper on the board. perhaps your problem is just a F6 setup issue.

push a picture of the board

[KevinOConnor]

I'm going to close this as I'm guessing the original issue was resolved (motor power needs to be supplied).

-Kevin

[szaghi]

@KevinOConnor I am very sorry for my huge delay. I have not yet found the time to check (the work is insanely huge in these days...), but I am almost sure you are right. I'll post my results as soon as I can.
