The configuration of the TMC2209 stepper drivers done in Configuration_adv.h seems to have no effect. I also believe that marlin 2.x doesn't always respect jerk and acceleration with new s curve algorithm, theres long threads in github about missed steps. (As noted on this page.) 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 Marlin is at version 2.0.6. That doesn't really explain anything. We install them on a SKR 1.3 board using the UART connectivity. If this is the case, Marlin offers you the possibility of resetting it with a simple button click, so it is not something to worry about excessively. Recv: Testing X connection...

Maybe I'll record the inconsistent homing behavior I'm seeing with sensorless homing and open an issue for that before cutting bits of my drivers off. Usually an end stop switch will, when triggered, connect the pin to ground for a LOW signal. Marlin 2.0 on the SKR 1.3 with TMC2209 and sensorless homing In this video, I show you how to configure Marlin 2.0 for the SKR 1.3 mainboard with TMC2209 stepper drivers and sensorless homing. This configuration is … At best it will be very unreliable, at worst you could damage the TMC2209. This means that the end stop pin is effectively tied to ground just like when the end stop switch is triggered. I can't find any information in how to install the TMC2209 to Marlin/RAMPS 1.4. I installed TMC2209 from Fysetc on my SKR 1.3 of my CoreXY and tried to get sensorless homing to work. This is the full result of M122 (TMC_DEBUG): Send: M122 BT99. However every once in a while one can get a 1.6A motor or in my case a 1.7A motor. The hardware I'm swapping from is mostly irrelevant, but it does indicate that I already have a working UART setup. Press J to jump to the feed. I have an Ender 3 with a BTT E3 Mini 1.2 Board. to your account. Trinamic drivers that support this feature are TMC2130, TMC2160, TMC2208, TMC2209, TMC2660, TMC5130, and TMC5160. The driver chip is relatively small and even at moderate 1.3A RMS motor current it gets very hot very fast. They also have one less pin than some other TMC2209 Steppers, so no need to clip or bend anything. We’ll occasionally send you account related emails. #define HOLD_MULTIPLIER 0.5 // Scales down the holding current from run current Max Current Output – On average the TMC2208 drivers are rated up to 1.5A (2.0A Peak) continuous motor output. #define INTERPOLATE true // Interpolate X/Y/Z_MICROSTEPS to 256, #if AXIS_IS_TMC(X) Recv: Enabled false false false false After powering up I've completed a number of troubleshooting routes, which includes buzzing out motor wires to make sure they are all … #define HOLD_MULTIPLIER 0.5 // Scales down the holding current from run current Marlin firmware mods for SKR 1.3 with TMC2209 stepper drivers - Configuration.h Posted by BT99 .

Recv: Driver registers: Successfully merging a pull request may close this issue. Steps to Reproduce. This is why we’re so eager about the UART Interfacing that these TMC2209 drivers offer, as it allows for far more control than the old Step/Dir method, allowing users to control all of the control lines (EN / DIAG / INDEX / MS1 / MS2 / Analog Current / VRef) via a single line of code. Recv: Z 0xC0:0C:00:00 The text was updated successfully, but these errors were encountered: Did you Initialize EEPROM after flashing? Even if you try to connect up the end stop switch to pull the pin to +VCC when triggered, you will be fighting with the TMC2209 which is trying to pull the pin low. This is why BigTreeTech tells you to snip the pin or desolder it and Marlin can't override it. Close. Recv: [mm/s] This is an example of my configuration: #if HAS_TRINAMIC_CONFIG.

This will require setting up a pull up and possibly a filter capacitor for each endstop. I have an Ender 3 with a BTT E3 Mini 1.2 Board. Crossposted by 7 months ago. The Creality printers (and most other consumer machines) will barely ever pass 1.0A of output needed for the stock motors. So let’s get to it without further delay. The only possible workaround without cutting the diag pins is to wire the endstop switches to different pins (for example on the AUX connectors). 3. This is the exact description of what the driver does. Additionally, UART Interfacing also allows for quick and easy configuration without having to rewire pins, with the actual software being … Having completed re-assembly and Marlin config, I am pretty sure that my motors are not being supplied with power.
