Recv: // Printer is shutdown Recv: // Klipper state: Not ready Recv: !! Unable to read tmc uart ‘stepper\_x’ register IFCNT ### Describe your issue: Hi. I’ve tried for days trying to get my printer working with closed loop s42c drivers, but I’m always getting the same error. Any and all searches on the web lead to dead threads, useless youtube videos, or phrazes “it’s plug and play”. But, it’s not plug and play, by just pulling out old tmc 2209 driver and sticking this one in. I’ve tried changing settings in printer.cfg to A4988, tried with the jumper for TmС and without… nothing works.

PLEASE upload the **klippy.log** as file **to your next post**. The code sippet of the printer.cfg you included as text is of not much use: - It is crippled - It is not formatted as code - You attached the printer.cfg file anyway. * * * You may check the UART wires You may swap the TMC drivers ---

Your printer.cfg looks completely different from mine )). And in your settings it looks like you have TMC set up. How did you manage to get the S42B drivers working? I either case, thanks for your help. I’m sure as I deep dive in to this, your file will be quite usefull. ---

Sorry I do not know how to respond… They just work. Notice I do not have any driver for the X or the Y only the definition is needed. For my 2 Z axes and the extrudes that are TMCxxx. I have changed a few things in my config, but that is for the encoder runout sensors… I still can not get all three of them to work, or get one of them to work more then once. But that is for a different post else were… ---

Hm… That just may be the answer to all things. )) I’m afraid to do any more experiments on current printer, since I had a brick sitting on the table for over 2 months and things to print were just piling up. Planning on buying another voron kit and go crazy on that one. Thanks againg for your help. ---

I have to ask a dumb question …. did you go thought the stepper’s calibration and setting in the stepper themselves ? they are dumb until you do. ---

If you mean the calibration using the 3 buttons on the pcb that is screwed to the back of the motor, then the answer is yes. It calibrated doing a full rotation and all was good. Problems start as soon as I send g28. ---

please make sure you test it without the steppers in the printer to see it they move in the correct direction. , or if you have the good direction tested and then when it tries to home, try just the x or y only. to make sure it is not the core xy vs core yx it it moves then crashes check the endstops. Remember troubleshooting first starts with power that you have… them cut the config to the minimal possible. Save you current config, rename it, start with a blank one and just do the x and y steppers. (maybe z) then add back to it ---

I heard your advice and tried uploading as a file, but it was 8.2 mb and would not upload. Then I cut out the top part of the file and tried using the Preformatted text tab, hit enter and this happened 😑 Then I tried to edit and added [], didn’t help. I’m sure that I didn’t do something right, just haven’t figured out what yet. ---

If files are too big just zip them and upload the zipped file. We are mostly dealing here with text files that can be compressed quite well. Regarding preformatted text you can test it here in the reply window and should see the result on the right hand side. Test it with a single word or small text to get familiar with it and then fire it up! 😉 ---
