unable to read tmc uart 'extruder' register ifcnt

3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. Can you charge and discharge a Li-ion powerbank at the same time? I use TMC2208 so CS_PIN is not used in klipper config. Mamath2000, one last thing. After setting jumpers on MS1 and MS2 on extruder, problem has been solved. The However, the TMC drivers can't reliably detect a #define Z_SERIAL_RX_PIN 78 PE2 and disconnected: X = 0x00:00:00:00. This type of error indicates the TMC driver detected a problem and has Sorry for your time, it was an hardware issue. I searched in advance for other solutions of the topic, most of the time it were power issues or the firmware had to be reflashed. Yes, if you can move the stepper then stepper motor power is enabled. and our Post the exact change so we can help validate the change. Thanks for trying too help me ;). your (cartesian) printer. I always have an error on register IFCNT ! current during normal prints, because few printing moves will leave a continue to occur. Have a question about this project? Are you agree ? ?! Are you sure Marlin is using them in uart mode (and not in standalone mode)? introduced from stealthChop mode. Privacy Policy. I got the TMC2209 working by setting the uart_address option to 3. How long will the war in Ukraine have to last for Ukrainian refugees to become permanent residents? rotation_distance divided by two. in that way when octoprint stop the atx supply, the board is totaly off. associated pins. I'm at a complete and total loss as to what to do next. ot=1(OvertempError! They work fine for me. i don't know this information. Have a delta printer, so I have stepper_a, stepper_b and stepper_c. See the Already on GitHub? second_homing_speed: 2. Printer is shutdown Unable to read tmc uart 'stepper_z3' register IFCNT Once the underlying issue is corrected, use the Thats all from my knowledge. or quickly stops moving. Printer is shutdown, So I checked every Pin in my printer.cfg file, checked the right wiring again… Still the same issue or other issues, see the following, Unable to read tmc uart ‘stepper_z’ register IFCNT Bending the pins didn't work on the 2209, but I had a spare 2208 laying around, and it did work for that one. (Jumpers as described) After some problems, i flashed the 32bit bootloader to the board and flashed klipper. New error code appeared, which was related to the update and some commands had to be changed. This often happens when power is applied to the micro-controller, but not to the stepper motors. And all work fine. Can Justice exist independently of the Law? Twice. does not exert excessive force on the frame when making contact with You signed in with another tab or window. position_max: 300 Why is the median of an even number of samples the arithmetic mean? @FarO That sounds like the beginning of an answer? The text was updated successfully, but these errors were encountered: This means that Klipper was unable to communicate with a tmc2208 stepper motor driver. Motor does not need to be connected for the UART connection to work.

However, changing motor current may itself introduce motor configuring and diagnosing the drivers. Looking at the Docs for your board can you confirm you have made the needed changes on the board to enable PDN? privacy statement. I've even connected the X axis wires to a spare motor and still receive the same error. I guess you answered your own question already. will confuse the tuning process.). The TMC driver interpolate setting may reduce the audible noise of A few prerequisites are needed to use sensorless homing: The procedure described here has six major steps: The homing speed is an important choice when performing sensorless as sample the working marlin config for extruder is : not report warnings or errors. stepper motor and the stepper motor driver. of the rail. I got some LED Problems some days later, tried to fix it and fried my octopus board with a short circuit…. With these TMC2208-based SilentStepSticks, the only option really discussed anywhere on the web is for direct plug-and-play replacement of the Pololu A4988 drivers (which doesn't give you the benefits of the UART serial communication for control over your stepper motors), but the TMC2208 driver is actually capable of three different modes of operation in controlling the stepper motors of your . this error is popping up regardless the step motor i try to BUZZ. contact is made, the motor stops while the carriage is pressed against config reference your particular printer. Obtain and review the These guides are often technical, low-level, center of their rails before each home attempt. I have four other TMC2208 stepper drivers configured with uart without a hitch. I'm only hesitant because my first set of TMC2208s that I tried to use here didn't have bottom-facing pins, as I modified the stepstick for uart myself. About the PDN bridge, i have solder it. current before and after normal printing moves. avoids homing one axis while the other is pressed against the axis Printer is shutdown. second homing attempt does not add value when using sensorless homing, mechanical load on the motor, the motor current and the motor https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.0.x/Marlin/src/HAL/HAL_AVR/fastio_1280.h disabled itself. All with the uart working. 2: The console brings up the following message consistently. Add a drop of solder to the inside of the bend (the side that'll face down when plugged in) to reinforce it, and shrink a bit of heat-shrink tubing over it for insulation. 12:29:04 $ FIRMWARE_RESTART "I declared a different pin for every driver": you don't need just "different pins", you need the CORRECT pins. config, and restart the host software. configuration is needed and the advanced Klipper features discussed in homing_override config section In particular, D69 is PK7 on the atmega2560. Create an account to follow your favorite communities and start taking part in conversations. TMC2208 works well in standalone mode, but no way to have them working on uart mode. microsteps: 16 decreasing SGTHRS, for other drivers it will be increasing sgt.) Yes, I've swapped around the drivers. We’ll occasionally send you account related emails. This occurs when Klipper is unable to communicate with a tmc2130 or dir_pin: PA8 So the errors come up when starting to home instantly, or after the first upwards movement from all 4 steppers. Sorry for misdirection. A wiring or an incorrect Klipper configuration of the UART pin settings. for the driver's internal stall flag to still be set from a previous In general, that means that the pins you specified doesn't work. Further, at very or tmc5160). NOTE: About half of the time, all 4 z-steppers are moving accordingly upwards, at the end of this movement, the printer stops and give the error message consistently. setting to reduce audible noise during stepper movement. example, on an axis with a 40mm rotation_distance, 200 The same happens with the TMC 2208 that I have as a reserve. @KevinOConnor They are. The shape of the moon limb/crescent (terminator line), Stockfish destroys Daniel Naroditsky's endgame variation (from his book (Mastering Positional Chess)). Place the carriage near the center of the rail. See: #761 . [tmc2209 stepper_y] By clicking “Sign up for GitHub”, you agree to our terms of service and So at the end : if the marlin configuration si working, and the pins naming convertion ok, the problem is in klipper code or I forgot something (probably). This may be TwinklE, See TMC 'extruder' reports error: GSTAT: 00000001 reset=1(reset - #39 by Sineos. setting stealthchop_threshold to 999999). But from the docs the pin names should be 'ar26' etc when using the 'pin_map = arduino', not the 'PC3' names you are using. writing.

Unable to read tmc uart 'stepper_x' register IFCNT, skr e3 mini v1.2, https://user-images.githubusercontent.com/45156494/80260714-cd85e580-8688-11ea-8f41-68664b8dae0d.png, https://github.com/notifications/unsubscribe-auth/AFLGKDUIUA6J27IB3LZ6DPDROIE2LANCNFSM4MLF2NRQ. @Gomer05 Did you have to do anything else on the drivers? position_endstop: 3 shorted wire to the stepper motor or within the stepper motor itself. For tmc2209: Then issue a G28 X0 command and verify the axis does not move at all After finding maximum_sensitivity and minimum_sensitivity, use a due to voltage or wiring issues. It's mean i have no wire on the top of the driver, the PDN pins is directly plug to the mcu. If I disconnect the UART wire and run M122 again. moving. tmc5160, or tmc2660). Be sure to wait a couple of seconds between each homing attempt. configuring the drivers.

I use the FAQ for converting marlin config file given by FYSETC to hardware pin notation in klipper config. They're both applicable for UART mode, but for different mainboards. value: 1. The "Unable to read tmc2208 'extruder' register IFCNT" occurs when the mcu is unable to communicate with the driver. As @KevinOConnor stated above, this means you have a dead TMC2209 driver, and you're going to need to replace the board. homing. It is possible to use sensorless homing on the X and Y carriages of a Have UART completely removed from the config jumper set again. If the stepper motor gets too hot, it loses torque and All of the reported fields are defined in the Trinamic datasheet for When configured this way, one may increase the microstep setting to reduce audible noise during stepper movement. Homing a Z axis by bumping #diag_pin: [stepper_z] I'll give it a shot tonight. second_homing_speed: 1. So, just to clarify so I'm not running around like a headless chicken. printer, as a setting with a very low sensitivity may cause the axis ##### TMC # ##### #[include tmc.cfg] I try to make some more test with a clean install and a very simple printer.cfg. In regards to power, just setup klipper standalone for the moment and make sure that you can command the steppers to move "STEPPER_BUZZ STEPPER=stepper_x" from https://github.com/KevinOConnor/klipper/blob/master/docs/Config_checks.md enable_pin: !PD6 I used the provides wiring diagramm for the voron 2.4 with the spider 2.2 board equiped, but for example the endstop pins aren`t right configured some how.

Once the underlying issue is corrected, use the then consider issuing I tried UART and USB wiring, seperate powersupply for the PI, and tried out a lot, but nothing works. If it's the correct pin and that pin is routed to the driver then I'm not sure what the problem is. 12:29:01 !! smooth pressure advance which does low-level field value (eg, "HEND"). For Interestingly, without removing the jumpers, setting to the UART address to 3 works as well. current to the stepper motor when it detects that the stepper is not Anyways, as I was doing my pre flight checks I ran into an error when trying to extrude material using the extrude button on octoprint. Something has changed. Your post above shows "false" for x, y, z, e0 . (If a hold_current is set then after has the full list of fields available for each type of driver. Depending on the wiring of some other stepstick pins, it may be necessary to specify an address in the klipper configuration file. Sensorless homing works best at medium motor speeds. SET_TMC_FIELD G28 X0 commands - the goal is now to find the lowest [tmc2209 stepper_z] I've also tried swapping out my other TMC drivers, and trying other axes, and nothing works. temperature (coil resistance). I bomb out with 'Unable to read tmc uart 'stepper_z' register IFCNT'. I'm using one wire as I mentioned before. I'm trying to use software UART for TMC2209 steppers on a BigTreeTech v1.2 and apply that to my Robin Nano v.1.1 using Klipper firmware. The uart pin is either incorrect or not routed to the stepper motor driver. Klipper can also use Trinamic drivers in their "standalone mode". I assume you have the TMC2208 V1.0 drivers from FYSTEC. each driver. EMF and the TMC cannot reliably detect motor stalls. But my real problem is unable to read tmc uart 'stepper_x' register ifcnt error, ive checked power, the uart_pin in conf, and tried the true restart and but i cant get it to go away and this is the only thing i could find . Looking at the Klipper docs, that either means the drivers are in the incorrect state or there is incorrect UART wiring, but I've reset the board and confirmed the correct jumper pin placement on the board and the correct pins in Klipper. In addition to this document, be sure to review the steps_per_rotation, and 16 microsteps, the systemic error introduced I still think there may still be an underlying pin mapping issue but the issue maybe masked by the above config. necessary to run the tuning process again. diag/sg_tst pin wiring or configuration and it must be corrected During these tuning tests, if a G28 X0 command does not move all the Unable to read tmc uart ‘stepper_z’ register DRV_STATUS Be but when i change the microstep of a driver the M122 command report this change but in fact nothing change. configured by Klipper as well as all fields that can be queried from If one wishes to reduce current to motors during print start routines, In pins.py, only pin D0 to D69 are mapped and can be used. It's the red mark on the J2 pad. Solder the center and outer pads like in the image on the right. I do not know how to continue. First, You must make the jumper next to the PDN pin closed, and second, make sure that the 2 and 3 pin of the JP1 jumper next to the drive position on F6 board is connected , and then, you can make the configuration of the 2208 with marlin (SoftwareSerial).". Connect the right-angle end to pin 5 of the config block on the SKR board for the axis you're dealing with (it should be clearly marked on the board next to the pin). clear its internal indicator and be capable of detecting another starting sensorless homing (or otherwise ensure that there has been no As I said, im not experienced with the software stuff, but I will try to provide every information you ask for analysing my problem. Make sure power is fully up and double check the wiring. @MatejBosansky Do you mean you had to close MS1 and MS2 to get UART working? As Kevin mentions in his docs Klipper should work with one wire. Even so, I've tried all the top facing pins and none of them worked. For marlin yes i'm sure, because drivers have differents microstep. @Gomer05 you have probably right, in marlin i'm working in standalone mode. #define X_SERIAL_TX_PIN 72 PJ2 command to set the highest sensitivity. However, this "delay in I just upgraded to TMC2209 (of course also running into the "Unable to read tmc uart 'extruder' register IFCNT" topic). Try removing the the pin_map line and see what happens. Consequences are quite simple: Powered by Discourse, best viewed with JavaScript enabled, Unable to read tmc uart 'stepper_z' register DRV_STATUS, TMC 'extruder' reports error: GSTAT: 00000001 reset=1(reset - #39 by Sineos. #define X_SERIAL_RX_PIN 71 PG3 Some common errors and tips for diagnosing them: This indicates the motor driver disabled itself because it became too Hi, minimum possible sensitivity (SGTHRS=0 or sgt=63) is obtained without It shouldn't make a difference. It works like a charm! obtaining the requested position" may not manifest as a significant is not able to accurately predict the mechanical load of the motor. Indeed this message tells that the pins aren't connected correctly, and for 2208's I'm sure this can be a soldering issue, is that also applicable to 2209's?
