Let’s take a step backwards and start from there, so we an try to get you going if the SKR survived.
You say above that wiring was good, but your steppers were moving backwards from the arrow directions. Most likely, this was because your stepper connectors needed to be flipped for whichever motors were moving in the wrong direction.
Flashing wasn’t, and isn’t, the starting point.
Now that you’ve done a bunch of random flashing, we’re going to have to sort that out.
Do you have a computer and USB cable that can let you run a gcode sender?
We may not need that, but since you’ve attempted to flash both the SKR and the TFT, your system is now in a bit of an unknown state.
One way we can check quickly if your system is completly blown or not without doing any more potential flash damage is to try and connect to the SKR over USB with a gcode sender.
What we need to do at this point is to carefully troubleshoot and decide which parts work and which parts don’t work, and then for each of those things we will need to methodically fix each one.
Please, no more random flashing. Let’s take this step by step and the community can help you find the right way forward.
Yes to USB and computer to connect to had connected in past but couldn’t get it talking to estl cam or something could you suggest a gcode sender please and I will try this thank you
There are two parts of the troubleshooting we want to do.
First, we want to see if your SKR USB is recoginized by your computer when you plug the USB in.
There’s a USB to UART chip on the SKR board, so when you plug it in, your computer should recognize that chip and a COM port should appear. How we do that test depends on what operating system you have. For windows, you need to be in device manager to see the USB enumeration and note what COM port shows up.
If a COM port doesn’t show up, then you either need the USB drivers, or the board is damaged.
If the COM port does show up, then we want to connect UGS to that port so we can send commands and see responses from the terminal.
The first commands we’ll send will be to ask marlin for diagnostic info.
If the COM port shows up but we can’t get commands to go into Marlin, then we’ll do some more troubleshooting around that.
There are many hundreds of running machines all over the world, so lots of folks have figured it out.
Your thread is still open if you feel up for constructive troubleshooting.
If you’ve made or would like to make progress that’s a great place to continue.
usb device dosnt seem to show on laptop it’s running windows 10 dosent show in device manager and the sender software doesn’t see it either was going to try another laptop but had lent it to a friend so was trying to get it back
That laptop may need USB to serial drivers in order to work.
When you plug it in, does an unidentified device show up in device manager, or does nothing at all happen?
If you get unidentified device then you need drivers for the board.
Using the square USB connector on the SKR is the correct port. The other port is intended to provide an option to plug in a USB stick, but that isn’t supported in the current SKR firmware.
That is my recommendation. All options I can think of now involve electrical test equipment and component replacement. Probably better to replace the SKR.
one last thing to check- on the SKR there is a jumper that sets whether the microcontroller gets power from USB. make sure that jumper is set if you’re only plugged into a computer,
yeah might be a bit before I can do that but next step thank you all for the help with this
