TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation,maximum efficiency and best motor torque. 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. This feature is so sensitive that it can actually take the place of traditional endstops. running SKR 1.3 /TMC2209/ COREXY just as OP. My M122 comes out as follows: New user coupon on orders over US $4.00. Obviously there are many people with problems using TMC2209 with sensorless homing. If you have different problems then open a different issue providing all information needed for it to be debugged. 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. The motor supply voltage VM is a strong power supply with a high voltage. It’s also a good idea to add these two lines [home bump] right after the sensitivity settings to … @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? SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. ), dedicated port reservation, wiring settings are more convenient. Interesting, even with a manual switch endstop override im only getting "Open" status, can somebody explain the need for enabling "#define SENSORLESS_HOMING"? We will not rush products out the door and waste our customers money just to make quick sales on products that are poorly designed and made. P.O. I can't get movement on the Z axis. The Creality printers (and most other consumer machines) will barely ever pass 1.0A of output needed for the stock motors. Someone else on a BigTreeTech FB group was having issues with a CoreXY too. 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. 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. X and Y always triggered. 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. Drivers were bought direct from Watterrot and M122 is returning valid looking driver register values, so … Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. Here is a video and the configs files in the description. View details & Buy. TX: 0V The TMC2208s are a very well supported and established stepper driver in this market. 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. 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. Marlin will then rehome Z axis and restore normal current setting. 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. Mine is working I am just setting the right sensitivity now. EN: 3V Because before this was only tmc2130 normal function. The TMC2209 is an ultra-silent motor driver IC for two phase stepper motors. So I can both confirm that it should work, but its not working, and its not in a state where it should work either. Jako předešlé modely umí spreadCycle, ale zároveň přináší vylepšený stealthChop2. The choice to go with the TMC2208 over the TMC2209 has many reasons that have to do with the machines the board is intended for and the design cycle of our board. It appears the pins have moved around on the new step drivers: 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 control Set sensorless homing sensitivity SENSORLESS_HOMING. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) I don't know - I switched to Bigtreetech Drivers instead of the Fysetc and it worked. I went for the TMC2130 over the TMC2208 because I want to play with setting crash detection on my Ender 3. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. If i remove endstop cable it's always triggering. Log in or sign up to leave a comment Log In Sign Up. This way it now connects the driver board to the SKR board and sensorless homing works correctly. They both are running StealthChop V2 for extremely quiet printing. 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. Yep, I have the same problem with MKS TMC 2209 on MKS SGEN_L. im sure i had it enabled before though. If I remember correctl the hybrid threshold is set to 0 during (sensorless) homing anyway. Actual behavior: Axis don't move, X/Y endstops are triggered. This solved all my problems, I feel so dumb! Can you use tmc2208 drivers with sensorless homing on an skr board or does it have to be 2209? I can confirm that the Hack suggested by @thisiskeithb works perfectly fine on my MKS SGEN_L with Watterott V2.0 drivers. We believe in FULLY testing our products before we sell them to you guys like a professional company should do. @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. The text was updated successfully, but these errors were encountered: I tried, but the sanity check won't let me: Always ensure that there cannot occur voltage spikes on power up. I don‘t think it is the SKRs fault, since sensorless homing works just fine using the Bigtreetech TMC2209. 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. So thanks to your picture and video I watch I've figured That by soldering 1 pin to the drivers it should work kept coming up with unrecognised USB device and i triple checked the serial settings? Pin 5 = TX Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. The strange thing is that there seems to be some really weird numbers on the z axis. Are your chips legit? 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. | Firmware Update, Re-wiring 2 Pin Fan Connectors | EZTip #7. TMC2209 says HIGH is triggered, so I guess the above should be correct. Right now my Y-Stepper is triggered forever. Box 137 Hours: 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. 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. | Firmware Update, Unified 2.16a is now live! It is very clear that they rushed to market as all of them had major electrical design flaws in their boards that all had later revisions performed and their early adopter customers were left with hardware that did not work and/or failed prematurely. I installed TMC2209 from Fysetc on my SKR 1.3 of my CoreXY and tried to get sensorless homing to work. So, in my case, sensorless homing worked fine for X and Y but as I said in the beginning, we wanna have this value as low as possible for both axis so we don't get any false positives during printing. I'm frustrated. TMC2209 DATASHEET (Rev. 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. TMC2209 pinning is compatible to a number of legacy drivers as well as to the TMC2208. StallGuard for sensorless homi… Can you post pictures of V2 and V2.1 so I can compare? 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? DIAG1/DIAG pin of TMCxxxx connected to the MCU 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. So what I'm going to do is reducing the sensorless homing sensitivity to 64, that's again in the middle of 0 and 128. The TMC2209 is an ultra-silent motor driver IC for two phase stepper motors. 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. Zároveň jako TMC2100 neumí sensorless homing. Sensor-less Homing (aka StallGuard) – The TMC 2209 added a new feature that was from the TMC2130 drivers. hide. 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. In none of them can I activate sensorless homing detection. Here's the demo video: I'll update the PR shortly with the AVR version. Instead, the TMC2130 can be used as a sensor. Putting a heatsink on top is not what Trinamic intended to be done to the TMC220X line of drivers. : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. 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.
