* in Marlin. Are your chips legit? Trinamic's sophisticated StealthChop2 chopper ensures noiseless operation, maximum efficiency and best motor torque. Details. https://wiki.fysetc.com/Silent2209/ Interesting, even with a manual switch endstop override im only getting "Open" status, can somebody explain the need for enabling "#define SENSORLESS_HOMING"? I have mine working around ~65. When I replace it with BTT TMC 2209 all works fine. I did however have to disable hybrid threshold, Ive subsequently changed around the settings and have toggled it, back to the state where I had previously made it to work, and now its not working. Nope, did that, did not work. It’s also a good idea to add these two lines [home bump] right after the sensitivity settings to keep the … This feature is so sensitive that it can actually take the place of traditional endstops. Also the TMC2209 on E not working with LIN_ADVANCE ON and SQUARE_WAVE_STEPPING OFF, I set up a bench test today with the new SKR 1.3, going to check these, i also have a new revision of TMC2209's (FYSETC V2.1) they seem to be setup differently to my FYSETC V2.0 so ill give them a whirl as well. [BUG] TMC2209 Sensorless Homing not working. Marlin 2.0 was very much in it’s infancy and required a lot of work to get it stable and working on most boards at the time. I wonder if a power cycle was necessary. Per Trinamics own datasheets they specify a 4 layer PCB with high copper content (aka 2oz) on each layer. US $47.50 - 66.00-27%. I can't get movement on the Z axis. After power on my settings are just fine.this is only about the TMCs. hide. The TMC2209 drivers with UART interface have a few more features, which can be used for motor current setting via software or sensorless homing when the driver is connected via UART to the mainboard. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. Then its time to remove those end-stop switches. to your account. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. New user coupon on orders over US $4.00. I fixed the board issue with my skr 1.3. i am trying to build my mks sgen l bored with tmc2209 v3 from fysetc and i am getting error low M-F 9AM to 5PM CST The TMC2208 drivers have been out for a long time now and well supported in many firmware that our 3D printers use. So thanks to your picture and video I watch I've figured That by soldering 1 pin to the drivers it should work Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. We’ll occasionally send you account related emails. I kinda have the same sort of problem. When I replace it with BTT TMC 2209 all works fine. Sign in Sign up for a free GitHub account to open an issue and contact its maintainers and the community. So please forgive my potato vision camera: https://imgur.com/a/cGOylQL, the only difference i can see visually on the V2.1 is the two 0 Ohm resistors across the PDN Line jumper pads instead of the single one on the V2.0, However, looking at the IC itself they have done a much better job soldering it on the V2.1 boards i have recieved with the markings clearly visible compared to the V2.0 - i hope they didnt wash these boards lol. Price should be similar. Seeing as all the machines we support with the EZBoard Lite have endstops from the factory we did not see this as a necessary feature and it is very inaccurate (think about power resume where you have to home XY again, you can be up to 0.2mm off on each axis). Each stepper driver constantly monitors the motor current that it is delivering to the motor, and this current changes dramatically when the load increases on the motor. kept coming up with unrecognised USB device and i triple checked the serial settings? None of the chinese boards are properly designed from a PCB copper weight per Trinamics own datasheets. solder bridged over the 0 Ohm resistor...all working fine on UART! I have sensorless homing disabled. Our board requires NO heatsinks even with the TMC2208 drivers because it is properly designed. It can support sensorless homing. ... Sensorless homing: disconnect X and Y endstops, BlTouch on Z-max and all *ST jumpers on. By clicking “Sign up for GitHub”, you agree to our terms of service and Jumpers on the SKR are closed any I ensured that there is an electrical connection between the DIAG pin and the endstop. The strange thing is that there seems to be some really weird numbers on the z axis. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. Also in the meantime I got a statement from a Makerbase Rep on this issue: 2209 seems to be unable to achieve senorless homing normally. I was able to get UART to work correctly by placing a jumper between the Rx and Txpins however sensorless homing didn't work so the motors did not move during homing and M119 showed the two ends stops triggered constantly. However if i return to mechanical endstops it works. My guess would a (design) problem on the Fysetc drivers. Interesting: Resetting the SKR (via the reset button) does NOT reset the TRIGGER state of the TMCs. This issue cannot be closed. After wiring up the drivers I started with the Marlin source that was already running properly on the printer, set the driver types in the config, enabled sensorless homing, and changed the pin numbering appropriately. TLDR; It takes time to test the hardware and firmware to ensure stability and reliability. Now it appears to be SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. In addition to making sure our parts are legitimate we also use name brand screw terminals from Phoenix Contact, the Chinese boards use no-name ones that are known to have issues with the terminals melting. And it is not surprising, since they have perfectly understood the “Maker” movement and have adapted to … Sensor-less Homing (aka StallGuard) – The TMC 2209 added a new feature that was from the TMC2130 drivers. id inspect the jumper 0 ohm resistors on the FYSETC TMC2209 boards if your having UART issues. I have Jumper on XST and YST. If i hold the endstop, press m119 i see triggered, if i let go it says open, all good TMC2209 DATASHEET (Rev. Heat Output – The TMC2209s do run a little cooler than the TMC2208 drivers. DIR : 3V, I'm kind of stumped as to how to get these connected to the SKR 1.3 board & working with UART as that was the reason I brought them (well I ordered the v2.1 versions). Pin 3 = TX - Or UART according to the wiki Hobart, IN 46342. If I remember correctl the hybrid threshold is set to 0 during (sensorless) homing anyway. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. The Red boxes represent the header jumpers to be fitted for X and Y homing If i remove endstop cable it's always triggering. I went for the TMC2130 over the TMC2208 because I want to play with setting crash detection on my Ender 3. In addition to that these other company boards are just barely getting working firmware (as of writing this article) thanks to work from people in the community and not the actual companies themselves. @paulpenney I think the fystec rep that was onto you is misinformed, My v2.1s required me to solder a solder connection between the TX and RX pins to get UART working. COVID19 Carrier Delays are Still Happening. If you have different problems then open a different issue providing all information needed for it to be debugged. TMC2209 SilentStepSticks can be switched between stealthChop and spreadCycle mode via a configuration pin (SPREAD). Close. Here is a video and the configs files in the description. It can replace the original TMC2208, A4988, DRV8825, LV8729 etc. They both are running StealthChop V2 for extremely quiet printing. put a jumper cable directly from diag pin X and Y driver to the Xmax and Ymax endstop pin, because the XST/YST jumper pin only connect diag pin to the Xmin and Ymin! I varied sensitivity from 0 to 250, but nothing changed. You are right the sensitivity value is a pain to find. ie the driver itself, what changes in config if any? I installed TMC2209 from Fysetc on my SKR 1.3 of my CoreXY and tried to get sensorless homing to work. also i found latest Marlin 2.0 sometimes when flashed with Platform.io bricks the SKR 1.3 - had to reflash Smoothie binary included in the bigtreetech github folder back to the flash storage and recompile fresh version of marlin 2.0 one setting at a time, not sure if its an actual setting within Marlin yet. The TMC2209s still suffer from availability issues due to poor yields in the silicon and large companies like Prusa buying most of them for their boards. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. However, the latest version of marlin2.0 confirmed the option to add 2209 senorless homing. [BUG] Harsh X axis sensorless homing on TMC2209, https://www.youtube.com/watch?v=dOJbSrWVu_Q. We'll have to see whether it's a problem with TMCStepper or within tmc_util. Log in or sign up to leave a comment Log In Sign Up. P.O. While this “works” on some machines it is only accurate to about 0.2mm of accuracy. Your personal data will be used to support your experience throughout this website, to manage access to your account, and for other purposes described in our privacy policy. I don‘t think it is the SKRs fault, since sensorless homing works just fine using the Bigtreetech TMC2209. Hey, im having exactly the same issue except my endstops are now reading "open" on X/Y but the motor just stutters as if its sensitivity to sensorless homing is very low? US $34.67 - 48.18. On the Fysetc TMC2209 V2.1 the diag pin is connected to the top of the board and there is no physical connection from the diag pin on the driver board to the header on the SKR board which is connected for senseless homing. Sensorless homing like on the TMC2130. Unified 2.16b is now live! ... Used sensorless-homing on mks sgen_l by set jumper cap like below (MKS TMC2209 V2.0): View more. and does not influence the actual endstop configuration in any way? TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation,maximum efficiency and best motor torque. Reference threshold, stallguard, sgresult. Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. #16220. I've upgraded the drivers on my Anycubic Mega from 2208's to 2130's because I want sensorless homing. this is the last thing to finish on my custom corexy and idk what else to try. The TMC2209 is an ultra-silent motor driver IC for two phase stepper motors. 1.03 / 2019-JUN-26) 2 www.trinamic.com APPLICATION EXAMPLES: SIMPLE SOLUTIONS – HIGHLY EFFECTIVE The TMC22xx family scores with power density, integrated power MOSFETs, smooth and quiet This means that we put over 10 months of testing and development into the EZBoard Lite that we are currently selling before we sold a single board to a customer. Zároveň jako TMC2100 neumí sensorless homing. Obviously there are many people with problems using TMC2209 with sensorless homing. It is working for me (FINALY): The problem was that everywhere it is written to connect Drivers DIAG1 to end stop pin. Pin 5 = SpreadCycle. DIAG1/DIAG pin of TMCxxxx connected to the MCU Stall Guard4£ºStall Guard can load and stall detection for stealthchop. I noticed that after a power cycle (actual unplug, not the reset button) all (any all everything, not just TMC driver settings) are set to 0 even though the correct values are stored in eeprom and loading the eeprom manually (M501 or via lcd) will fix it. TMC2209 says HIGH is triggered, so I guess the above should be correct. TMC2208-EVAL. I think the issue lies in the firmware as its not reliable at all on the skr 1.3. In addition to that we also went with the high end LPC1769 over the cheap (and limited) STM32F1XX processors due to its large memory, fast CPU speed, on-board EEPROM memory, and great support in the Marlin firmware. Technical Support For FYSETC Product! While i have sensorless home ON they don't work and printer react to mechanical endstops. 3. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. Level your X axis by trying to move the Z axis past its physical limit. This information applies to TMC drivers that are integrated to the mainboard. TMC2209 pinning is compatible to a number of legacy drivers as well as to the TMC2208. SpreadCycle : 3V (when the UART pin is connected on the jumper) - 0V otherwise The TMC2208-EVAL allows you to explore all ... current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding StallGuard4 for sensorless homing. @TheNitek will close this one as it seems mostly to be bad hardware, we can always reopen if there is an issue we can figurre out, @boelle Can you figure out why the sensorless homing will work for me when hybrid threshold is set to 0 only? StallGuard for sensorless homing. Lately the new electronic boards of the company BigTreeTech (SKR V1.4 and SKR 1.4 Turbo) are enjoying quite a notoriety within the world of 3D printing. Pin 5 = TX TH3D Studio LLC V3.0: Visão geral: Tmc2209 tem toda a função de tmc2208, pode substituir completamente tmc2208. Can anyone confirm that it works when hybrid threshold is set to 0? Other boards on the market advertising 2oz copper only have 2oz on the top and bottom layers, their inner layers are 0.5oz (which is standard for most 4 layer PCBs, and cheaper). We had our first prototypes made and testing of the hardware and software started in August 2018. Using the correct PIN sensorless homing works in general. It can support sensorless homing. Thanks again!! This means that you can use the driver to act like an endstop by ramming your hotend or bed up against your printer frame instead of an endstop switch. I don‘t think this issue is related. I ran a m122 and got the results below. Mine is working I am just setting the right sensitivity now. Hi, I have read this thread & stupidly thought that my TMC2209 from Fystec were the same as mentioned above & tried joining a couple of the pins etc... turns out I have been sent Fystec v3.0 and trying to get them to even work on the BTT SKR 1.3 board. The EZBoard uses 4 layer PCBs with a custom copper content of 2oz PER LAYER. I don't plan to invest more time in crappy drivers. If you see a board with Trinamic drivers on it and the heatsinks are on the tops of the chips (like the BigTreeTech, FYSETC, and Creality boards) this means they are trying to compensate for a cheap PCB by putting heatsinks on top.
