Hello any help would be hugely appreciated purchaced a kit a while back for the lowrider 3 and build using the guide on the website had it running( in its test phase) but had an issuse with homing going backwards to arrow directions. So from forums decided to flash firmware for skr-pro board now nothing wants to move tried few other firware file but to no avail the system setting on LCD screen show in info system : unknown system machine: 3d printer board : bigtreetech_Gd_tft35_v3.0 firmware:v27.x feb15 2023 in 120mhz SPIFLASH USED 96.78%
THE SKR-PRO BOARD IS BIGTREETECH SKR-PRO- V1.2
dose anyone know of anyways to get this moving again wireing is good and all was good till flashing attempts please any help as I scoured everything I can find and read thread after thread please help thank you in advance
Welcome to the forums, folks here will help you get things sorted out.
Did you purchase the controller from the V1 Shop? If so, it should have come pre-loaded with the proper firmware. Since that firmware did have it moving, but had some hiccups, probably the best thing to do is try to put back on the firmware that was originally on it (or the most up to date version available from V1).
(clipped out incorrect links - see recommendations below)
I don’t have a Lowrider myself, and use a different controller. Folks with first-hand experience should be along soon with additional guidance.
Once you do get moving again, double-check the endstops are working properly. The homing cycle moves to trip the switch, then backs off, so “homing in the wrong direction” may be caused by a switch already being tripped when the cycle starts.
If your board came from V1 it already had the correct firmware. You just needed to swap the connector to change motor directions. Check out this page for explanation on how to do that.
thank you for coming back to me flashed the firmware linked but still no movement or still saying no printer attached ? yes it was preconfigured from V1 when I got it
thank you had don’t that to get them going the correct direction for the arrows but maybe the homing thing was a stopper motor being triggered and them in the wrong hole but now I think its a firmware issue
I flashed the tft screen also might that stop it form talking to skr board or something or maybe memory is full and firmware not loading on even thought file extension changes ??
It sounds like you have made several changes that were probably better left unchanged. No matter, let’s try to get you working again…
Firstly, I think that the link that @ttraband gave you may have been incorrect. You want the file titled “V1CNC_SkrPro_DualLR_2209” (note the “LR” in the filename).
Secondly, if you reflashed the TFT, you may need to flash that again with the correct firmware.
You should start by going to the V1E Docs page for SKR Pro here.
Then scroll down to the FIRMWARE and TFT sections to find the links for the files you need.
For the SKR firmware , after you follow the link to the Github page, you need to go to the bottom of the list of the most recent release (currently V515 Marlin 2.1.1) , then select “show all 37 assets”. This will display all of the available V1E firmware releases. Scroll down until you find the one for SKR Pro DualLR (careful, there are some other versions like Turbo or V1.3 that look similar).
Then follow the instructions on the V1E documentation page to reflash the firmware using an SD card.
For the TFT file, it is similar. From the TFT section of the documentation page, select the link for the TFT Github page , then select the latest stable version (currently 3/22/23 Bugfix Rollup). Download the zip file and follow the instructions on the V1E documentation page to install the files.
Note that after you have finished, it may take up to 30 seconds for the TFT to see the SKR Pro, so don’t despair if the “Printer not connected” message shows up to start. If it persists, then report back, as it may be a wiring issue.
Can you please post pictures of your SKR board, showing the cables going to the TFT board, and also photos showing the same cables where they attach to the TFT board. I want to check if your connections are somehow crossed or otherwise incorrect.
Also its better if you pull the plastic guards from around the sockets where you want to hook up DuPont connectors. They will slide on much better and be much more secure. Like they are now you will be fighting loose connections all the time ( I speak from personal experience here ).
so are you suggesting the skr-pro bored is fried or bricked ? and tried flashing the correct firmware im told but it dosent seem to change this am I correct in thinking to place extracted files on root of sd card and inserting in sd card reader for tft panel and letting it do the update thing and for the skr bored the if the .bin file changes to .cur that it has flashed ? as these happen but info screen stays like this picture
What’s the obsession with flashing at the drop of the hat?
If it was V1 sourced, it shipped with everything already correctly configured.
You shorted the 5V rail with the endstops. The 5V LED is now on, so you’ve cleared the fault with the endstop. You may, or may not have, blown the board with just that.
You have also repeatedly tried flashing the board, when it didn’t need that.
You may, or may not have, corrupted flash.
If the microprocessor is alive, and the voltage regulator is healthy, but the flash or bootloader is borked, then it could still be fixable. But all of that is racing down rabit holes that might make things worse.
No, you have it completely wrong.
To flash firmware in an SKR Pro board, you put firmware on an SD card and put that in the SD card reader on the SKR.
To flash firmware on a TFT35, you extract the firmware distribution onto a freshly FAT32 formatted SD card and put that in the TFT35 SD card reader.
Two totally different microcontrollers, and two totally different flashing methods.

Welcome!
If I am saying something you already knew, please forgive me.
The TFT and the board each have their own firmware. Flashing one does not affect the other.
