X and Y always triggered. I wonder if a power cycle was necessary. This information applies to TMC drivers that are integrated to the mainboard. MS2: 0V Box 137 Mine is working I am just setting the right sensitivity now. Does it work with sensorless homing uncommented in the config? Obviously there are many people with problems using TMC2209 with sensorless homing. It appears the pins have moved around on the new step drivers: Printer moves korrekt, but even software endstops won't work. This way it now connects the driver board to the SKR board and sensorless homing works correctly. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. Can you post pictures of V2 and V2.1 so I can compare? Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. Stall Guard4£ºStall Guard can load and stall detection for stealthchop. 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 have SKR1.3 + ender3 and endstops work without remove diag jumpers. Use our official configuration first and open SENSORLESS_HOMING , if that works , then compare our configuration to yours , … This is not an issue since we did not cut corners like other companies on the copper and layer content of our EZBoard. 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. @sn4k3 I have the SKR1.3, I have my config in github. ... Used sensorless-homing on mks sgen_l by set jumper cap like below (MKS TMC2209 V2.0): View more. this is very bizzare as i can read positive voltage from TMC2209 DIAG1 to Xmin signal pin? Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. 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. The strange thing is that there seems to be some really weird numbers on the z axis. @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? Drivers were bought direct from Watterrot and M122 is returning valid looking driver register values, so … @TheNitek can you enable hybrid threshold for x and y and set them both to 0 then play around with sensorless homing sensitivity. Obviously there are many people with problems using TMC2209 with sensorless homing. SpreadCycle : 3V (when the UART pin is connected on the jumper) - 0V otherwise Hobart, IN 46342. Just tried again and now the printer moves (not having a good sensitivity yet). Unified 2.16b is now live! Visão geral: Tmc2209 tem toda a função de tmc2208, pode substituir completamente tmc2208. 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). While this “works” on some machines it is only accurate to about 0.2mm of accuracy. 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. P.O. The TMC2208s are a very well supported and established stepper driver in this market. Are your chips legit? We'll have to see whether it's a problem with TMCStepper or within tmc_util. with jumper pin still in XST and YST, download the source from Marlin main repo, adjust the config accordingly and compile from there.. seems the BTT repo is outdated, no cable jumper required here.. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Actual behavior: Axis don't move, X/Y endstops are triggered. TMC2209 pinning is compatible to a number of legacy drivers as well as to the TMC2208. The endstops only work when i remove the tmc2209 from my skr1.3 Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding StallGuard4 for sensorless homing. Reference threshold, stallguard, sgresult. I have the SKR 1.3 board and Fysetc TMC2209 V2.1 driver boards. So thanks to your picture and video I watch I've figured That by soldering 1 pin to the drivers it should work EN: 3V Instead they switched to the TMC2208 for a while so they could ship their boards. solder bridged over the 0 Ohm resistor...all working fine on UART! 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. My M122 comes out as follows: Stallguard is disabled i guess? 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). Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. m122: Stallguard thrs 0 0 0 0. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. 100% Upvoted. 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). This issue has been automatically locked since there has not been any recent activity after it was closed. Details. #16220. It can support sensorless homing. Per Trinamics own datasheets they specify a 4 layer PCB with high copper content (aka 2oz) on each layer. Then its time to remove those end-stop switches. US $47.50 - 66.00-27%. report. 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. The Orange lines are where they are wired to onboard. I went for the TMC2130 over the TMC2208 because I want to play with setting crash detection on my Ender 3. 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. But I could not manage to get sensorless homing working with the MKS 2209 drivers, no matter what I tried. StallGuard capable TMCxxxx stepper driver 2. Have a question about this project?

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. There are absolutely zero differences in print quality between the 2208 and 2209 since they are both using the same core technologies to control the motors and they are the same noise levels. im assuming this is only necessary for the TMC drivers themselves? Your stock endstop switches on a Creality machine are accurate down to 0.02mm or less. 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. Instead, the TMC2130 can be used as a sensor. I have sensorless homing disabled. MS1: 0V Jumpers on the SKR are closed any I ensured that there is an electrical connection between the DIAG pin and the endstop. - i say this because when hooking up a z probe in Z-min for example no software change is necessary? 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.

Sensor-less Homing (aka StallGuard) – The TMC 2209 added a new feature that was from the TMC2130 drivers. They both are running StealthChop V2 for extremely quiet printing. TLDR; TMC2208s are much easier to get in bulk from genuine suppliers and due to how long they have been out they are proven to be reliable drivers. I don't want to use stallguard yet so i have my default ender3 endstops. If I remember correctl the hybrid threshold is set to 0 during (sensorless) homing anyway. hide. TMC2209 DATASHEET (Rev. Sort by. It's possible that the stepper init for 2209 is still missing a step. Nope, did that, did not work. Thanks again!! 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. 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. Here's the demo video: I'll update the PR shortly with the AVR version. 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: Pin 3 = NC As of writing this article there are still issues with the sensor-less homing working correctly on the 2209 drivers and Marlin 2.0. If i hold the endstop, press m119 i see triggered, if i let go it says open, all good It allows the motor to detect step loss at up to 1 full step of the motor. Compatible with existing 3D printer electronics, with a standard step/dir interface, it is easy to use. I ran a m122 and got the results below. The motor supply voltage VM is a strong power supply with a high voltage. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. In this way, if in the future you want to change the configuration and use them in Sensorless mode (without mechanical limit switches), you can do it without any problem. Many of the other companies (like Big Tree Tech and FYSETC) pulled a bait and switch on their customers because they couldn’t get TMC 2209 chips for their boards. I kinda have the same sort of problem. save. Stepstick boards due to their small size usually will require heatsinks to keep the TMC drivers cool. Can you use tmc2208 drivers with sensorless homing on an skr board or does it have to be 2209? ), dedicated port reservation, wiring settings are more convenient.

Stall Guard4£ºStall Guard can load and stall detection for stealthchop. Right now my Y-Stepper is triggered forever. I have Jumper on XST and YST. 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. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. 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. So I ended up with Watterott drivers on X and Y and MKS drivers on Z and E. UART is no issue on either of the drivers. Happy! The device has a step and direction interface and can be configured with digital pins. Sign in It is expensive to go to a 4 layer, 2oz copper PCB so they do not do it to cut corners. I tested it with Marlin versions 1.1.8, bugfix-1.1.x and bugfix-2.0.x. We get this question a lot and we see some people saying that they don’t want the EZBoard because we are not using the latest TMC2209 drivers from Trinamic. 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. TMC2208.
