I kinda have the same sort of problem. If you want to add sensor-less homing to your cr-10 and have the tmc2130 drivers all configured and ready to go. The TMC2209s were rumored right around the time of launch and availability was extremely sparse (and still is hard to get due to poor yields at TMC). Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. It is working for me (FINALY): The problem was that everywhere it is written to connect Drivers DIAG1 to end stop pin. EZTip #2 – Removing Stress Marks from Printed Parts. Close. 6 comments. DIAG1/DIAG pin of TMCxxxx connected to the MCU 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. Our board requires NO heatsinks even with the TMC2208 drivers because it is properly designed. Then its time to remove those end-stop switches. Visão geral: Tmc2209 tem toda a função de tmc2208, pode substituir completamente tmc2208. MS1: 0V When i add my tmc2209 to the board, do the same thing, the endstop status allways stays open | Firmware Update, Unified 2.16a is now live! Sensorless homing is simply having no physical sensors mounted on the printer. Details. In none of them can I activate sensorless homing detection. @spazwart What board you use? 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? M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) EN: 3V While i have sensorless home ON they don't work and printer react to mechanical endstops. I know this thread is about sensorless homing on the TMC2209, but was hoping someone with skill can help me at all :), Just to close the above : for v3.0 of fystec drivers you have to follow the jumpers mentioned here to even get them to work: Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. Yep, I have the same problem with MKS TMC 2209 on MKS SGEN_L. id inspect the jumper 0 ohm resistors on the FYSETC TMC2209 boards if your having UART issues. Can you post pictures of V2 and V2.1 so I can compare? The TMC2209s are still very new so a board cannot be tested for 10+ months when using the TMC2209s when they have not been out for that long. Yep, I have the same problem with MKS TMC 2209 on MKS SGEN_L. US $34.67 - 48.18. Step: 0.2V If // Stall detection DIAG = HIGH : TMC2209, the pullup doesnt make sense. ie the driver itself, what changes in config if any? : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. Can anyone confirm that it works when hybrid threshold is set to 0? Thanks again!! The TMC2209 are rated up to 2.0A (2.8A Peak). I have adjusted sensitivity from 0-255 and even taken the belt off my XY but the motor still just turns maybe 2/5mm before stopping on a home command? 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. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. running SKR 1.3 /TMC2209/ COREXY just as OP. to your account. https://wiki.fysetc.com/Silent2209/ TLDR; The Creality machines do not need more than 1A per stepper driver and sensorless homing is useless (and inaccurate) on a printer that already has endstop switches. Marlin will then rehome Z axis and restore normal current setting. @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. I don't know - I switched to Bigtreetech Drivers instead of the Fysetc and it worked. If you're only going to use them as standalone (drop in replacements) there's not a lot of difference, although I would say the cooling is a big factor as the TMC2208 generates quite a bit of heat that's why it needs such a big heatsink and active cooling. I'm frustrated. Level your X axis by trying to move the Z axis past its physical limit. hide. When I replace it with BTT TMC 2209 all works fine. I don‘t think it is the SKRs fault, since sensorless homing works just fine using the Bigtreetech TMC2209. The Red boxes represent the header jumpers to be fitted for X and Y homing Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. I don't plan to invest more time in crappy drivers. It is expensive to go to a 4 layer, 2oz copper PCB so they do not do it to cut corners. Per Trinamics own datasheets they specify a 4 layer PCB with high copper content (aka 2oz) on each layer. I can confirm that the Hack suggested by @thisiskeithb works perfectly fine on my MKS SGEN_L with Watterott V2.0 drivers. The second part of RABZY88's solution above: #14464 (comment) works for the Fysetc TMC2209 V2.1 driver: I had to desolder the diag pin and invert it on the driver board. New user coupon on orders over US $4.00. The flexible microPlyer interpolation unit provides up to 256 subdivisions, allowing perfect sinusoidal control even in systems with limited pulse frequencies; these are also designed because stealthChop2 ultra-quiet technology is widely used in 3D printing. Now it appears to be Successfully merging a pull request may close this issue. None of the chinese boards are properly designed from a PCB copper weight per Trinamics own datasheets. 3. We personally did all firmware testing and configuration in house instead of tossing out hardware to our customers without working firmware like these other companies did (and still do). 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). The TMC2208s are a very well supported and established stepper driver in this market. Same setup here SKR 1.3, and BTT TMC2209 v1.2, was having the same problem using source from BTT repositories, my situation was trying to home to XMax and YMax, found 2 possible solution. I put the endstop cables on the SKR in the G and S pins in the endstop min pins. The text was updated successfully, but these errors were encountered: I tried, but the sanity check won't let me: I have Jumper on XST and YST. Sort by. privacy statement. 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. Always ensure that there cannot occur voltage spikes on power up. X and Y always triggered. @TheNitek can you enable hybrid threshold for x and y and set them both to 0 then play around with sensorless homing sensitivity. 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. SpreadCycle : 3V (when the UART pin is connected on the jumper) - 0V otherwise Instead, the TMC2130 can be used as a sensor. ", maybe @teemuatlut can say something, why the behavior does not correspond to the TMC2130, so I guess this is as intended. Where these drivers differ are as follows: Max Current Output – On average the TMC2208 drivers are rated up to 1.5A (2.0A Peak) continuous motor output. StallGuard for sensorless homing. 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. We believe in FULLY testing our products before we sell them to you guys like a professional company should do. After that I need to cleanup the configuration.h parameters a bit an we should be good for now. Just tried again and now the printer moves (not having a good sensitivity yet). Log in or sign up to leave a comment Log In Sign Up. I am really confused, because with my SKR 1.3 and BTT TMC2209 V1.2 sensoress homing won't work, regardless of what setting i choose. Jako předešlé modely umí spreadCycle, ale zároveň přináší vylepšený stealthChop2. so that was the only change? I have watched this video https://www.youtube.com/watch?v=dOJbSrWVu_Q configure everything as he has set the sensitivity to 50 now it works. TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation,maximum efficiency and best motor torque. MS2: 0V Actual behavior: Axis don't move, X/Y endstops are triggered. I'm frustrated. Drivers were bought direct from Watterrot and M122 is returning valid looking driver register values, so … 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. This issue has been automatically locked since there has not been any recent activity after it was closed. StallGuard for sensorless homi… Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding StallGuard4 for sensorless homing. Compatible with existing 3D printer electronics, with a standard step/dir interface, it is easy to use. Stall Guard4£ºStall Guard can load and stall detection for stealthchop. 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 Creality printers (and most other consumer machines) will barely ever pass 1.0A of output needed for the stock motors. Already on GitHub? I wonder if a power cycle was necessary. This information applies to TMC drivers that are integrated to the mainboard. 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. We wanted to make sure that we had reliable parts going on our boards that we were also able to get in high quantities to produce our boards with. this was designed to completely enclose the xaxis belt drive and is only useful for sensorless homing! We purchase ALL our main IC parts from verified vendors like Digikey and Mouser to ensure that we get genuine parts from the real manufacturers. You are right the sensitivity value is a pain to find. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. Posted by 7 days ago. TLDR; The Creality machines do not need more than 1A per stepper driver and sensorless homing is useless (and inaccurate) on a printer that already has endstop switches. ), dedicated port reservation, wiring settings are more convenient. UART mode: TMC2209 support UART mode. The EZBoard uses 4 layer PCBs with a custom copper content of 2oz PER LAYER. Compatible with a variety of drivers and special modes (TMC2208 UART mode, TMC2130 SPI mode, etc. The Orange lines are where they are wired to onboard. It can support sensorless homing. The device has a step and direction interface and can be configured with digital pins. TMC2208 SilentStepStick; TMC2209 SilentStepStick; TMC5160 SilentStepStick; General SilentStepStick Pinout of all TMC2xxx v1.x: General SilentStepStick Pinout of all TMC2xxx v2.x and TMC516x v1.x. I have one outstanding issue that I am perplexed by. Having the 2.0A is nice for bragging but it is not needed at all on the consumer printers, especially the Creality Machines that have small motors. I got sensorless homing working for a while then it stopped working ! RX: 0V Ok it just gets weirder and weirder, got the V2.1 TMC2209 drivers installed and got no UART on any of them, replaced it with a known good V2.0 and got UART...so I buzzed out the 0 OHM resistors... nothing... no circuit. After all, the 2209 chip has just been released for several months. TMC2209 says HIGH is triggered, so I guess the above should be correct. It appears the pins have moved around on the new step drivers: 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. 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. Changing the drivers from the 2208 to 2209 at a moments notice would mean selling you products that we could not faithfully say were tested to their fullest extent in terms of software and hardware. Instead, the TMC2130 can be used as a sensor. ... TMC2209 SilentStepSticks feature coolStep and stallGuard4 (optimized for stealthChop), which can be used for sensorless homing for 3D printers. Putting a heatsink on top is not what Trinamic intended to be done to the TMC220X line of drivers. ... At digikey TMC2130 is more expensive than TMC2208, so using TMC2208 would be cheaper. My guess would a (design) problem on the Fysetc drivers. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. Reference threshold, stallguard, sgresult. Také neumí sensorless homing. Obviously there are many people with problems using TMC2209 with sensorless homing. However if i return to mechanical endstops it works. I am only going to detail the steps necessary to make the TMC2209 work without sensorless homing, ... /** * TMC2130, TMC2160, TMC2208, TMC2209, TMC5130 and TMC5160 only * The driver will switch to spreadCycle when stepper speed is over HYBRID_THRESHOLD. 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. i would check the DIAG resistors/links but its pretty late, If my sensorless endstops still dont work thats the next thing im going to inspect. Because before this was only tmc2130 normal function. TMC2208 is designed for a supply voltage of 5...36V. i am trying to build my mks sgen l bored with tmc2209 v3 from fysetc and i am getting error low 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. It’s also a good idea to add these two lines [home bump] right after the sensitivity settings to … I don‘t think this issue is related. solder bridged over the 0 Ohm resistor...all working fine on UART! Interesting: Resetting the SKR (via the reset button) does NOT reset the TRIGGER state of the TMCs. BigTreeTech and FYSETC who are putting out boards with the TMC2209s spent less than a month from the time they came up with the same idea we had (32bit drop in for Creality machines) until they sold boards to customers. - i say this because when hooking up a z probe in Z-min for example no software change is necessary? For sensorless homing, the default sensitivity setting should be ok for most printers, but of course you can play with it if it is too sensitive or not sensitive enough. m122: Stallguard thrs 0 0 0 0. control Set sensorless homing sensitivity SENSORLESS_HOMING. Can you use tmc2208 drivers with sensorless homing on an skr board or does it have to be 2209? Compatible with existing 3D printer … We'll have to see whether it's a problem with TMCStepper or within tmc_util. im sure i had it enabled before though. I don't want to use stallguard yet so i have my default ender3 endstops. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. Pin 5 = TX While this “works” on some machines it is only accurate to about 0.2mm of accuracy. Stallguard is disabled i guess? It allows the motor to detect step loss at up to 1 full step of the motor. share. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. TLDR; The Creality machines do not need more than 1A per stepper driver and sensorless homing is useless (and inaccurate) on a printer that already has endstop switches. Sensorless homing included! Hours: [BUG] Harsh X axis sensorless homing on TMC2209, https://www.youtube.com/watch?v=dOJbSrWVu_Q. However, the latest version of marlin2.0 confirmed the option to add 2209 senorless homing. did you find a solution for it. Compatible with existing 3D printer electronics, with a standard step/dir interface, it is easy to use. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. We’ll occasionally send you account related emails. A few prerequisites are needed to use sensorless homing: 1. Using the correct PIN sensorless homing works in general. TH3D Studio LLC This solved all my problems, I feel so dumb! Pin 3 = NC StallGuard capable TMCxxxx stepper driver 2. 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. That‘s just the normal setup you have to do for the SKR and that‘s exactly the setup which doesn‘t work. Ao mesmo tempo, tmc2209 tem melhor dissipação de calor, suporta maior corrente, função sensorless-homing do apoio. Hobart, IN 46342. I ran a m122 and got the results below.
