how about the were to find the

The tft firmware is for the v2_e3, which has a knob. But you can compile it for the v2 without the knob.

You pasted a picture from that repo, so I assumed you already knew the answer to that. We haven’t compiled it for your screen, but the release page you posted is where the code is.

I am having a field day with SKR boards I just cannot win
loaded
V1CNC_SkrPro_Dual_2209-2.0.7.2-src.zip
changed the TMC 2130

Printer is now online.

Any help will me appreciated

Do you have power running to the motors on the new board?

spinorose · November 20, 2020, 7:27pm

I had to do these steps to revive the board

For clarification :

Jumper BOOT0 Pin to 3.3V
Get and FTDI Adapter,
Download https://www.st.com/en/development-tools/flasher-stm32.html
Make sure logic voltage switch on FTDI Adapter is 3.3v
Connect to SKR Pro 1.1 as follows : Connect FTDI 3.3v and ground to SKR 3.3v (near UART CONNECTOR) and ground pins
Connect FTDI TX to TFT Connector RX1 and FTDI RX to TFT Connector TX1 (For me the UART TX and RX Pins didnt work)
Open Demonstrator GUI, select the correct com port click next. If error appears, check wires
If OK, message will confirm connection Click Next again and and Next Again
In the next screen click the … near the downoad to device section and select the .BIN file to upload.
Click next and wait.
When done, dont forget to remove the BOOT0 jumper.

FYI Marlin firmware does not contain the bootloader, you’ll need a copy of firmware which includes the bootloader.

Phew !!! any one know what causes this Error ? I am using TMC 2130 V3.0

spinorose · November 20, 2020, 7:45pm

None of the stepper motors will still not move

spinorose · November 20, 2020, 9:01pm

Yes and still not movement

jeffeb3 · November 21, 2020, 2:40am

That is not dual endstops firmware. There should be 5 motors, not 3. Makes me wonder if your 2130 firmware made it on there.

That is saying it can’t talk over spi to the drivers. They are missing power, or they aren’t connected (are the jumpers right?). The firmware is configured for the wrong drivers. Or the drivers are soldered in standalone mode.

spinorose · November 21, 2020, 5:34am

I ordered the TMC 2209 and hopefully they show up .Thanks

spinorose · November 21, 2020, 5:36am

one other thing I noticed was whenever I have the Micro usb in the skr proI get printer not connected on the is display is that normal?

spinorose · February 18, 2023, 4:10am

Hi Guys ,

I am back at it again I change the drive to Tmc 2130 my question is do I bend any pins on the driver itself ?

This is results I get when I do and M122

Spinorose:

		Y2	0xFF:FF:FF:FF	 Bad response!
		Z	0xFF:FF:FF:FF	 Bad response!
		Z2	0xFF:FF:FF:FF	 Bad response!

This indicates there is no communication between the skr pro and any of the TMC drivers.

It does look like you are using dual endstop low rider firmware now though. Do you have a low rider or a primo?

The TMC2209 use UART to talk to the skr. The 2130 use SPI. The jumpers on the skr pro need to change to connect the spi instead of uart.

In he manual on pg 12/18, it shows which jumpers need to be installed for spi mode.

The MOTOR power input also needs to be connected:

You can see how the 12V comes in to two places on the right.

The bent pin thing is to disconnect the sensorless homing pin. You don’t have to worry about that yet. The motors need to tall to the skr pro and actually move before you worry about endstops.

And just like that it works - you are the Greatest Of All Time ( GOAT) . I highly appreciate all the support and I am building a Low Rider V3 . Thanks

Guys what is the best bin file to add to my folder ?
Bigtree LCD

jeffeb3 · April 20, 2023, 9:55am

Add them all. The screen will choose the right one.

spinorose · October 28, 2023, 2:21am

Can Some give me an idea where to connect Z endstop on my setup - I do not see one on this picture .
Do I need to make any modification to the firmware in order to use this set up . Thanks
