Help with Firmware Skr 1.2 tft35 v3

Hi everyone, I’m very new to this. I have my kit for my lowrider2 a year ago but due to health problems I had not been able to do anything. I wanted to know could you help me with the firmware for Skr 1.2 tft35 v3. I don’t know if there will be a place to find the files as if there is also a video or guide to know how to update the firmware. I hope you can help me thank you very much.

I put the firmware for TFT like instruction but now the screen is like this. Some idea why is this?. Sorry for my English.

According to the above, that means the skr cannot talk to the Drivers.

Do you have the drivers installed, and jumpers correct??

This information gives me from Repetier-Host. I really don’t understand much, I’m more than a novice at this.

So the info looks good. Do you have 2 pair of power connections??

Yes, the power to the board and from there a bridge to power the motors. The motors are handled by Repetier, but if I want to move them from the touch screen, the message “printed not attached” appears and the motors are not moved. That’s normal?. Because my idea is to drive the lowrider2 directly without a pc, can this possible?

In the screenshot, the screen is in marlin mode. But it shows the tmc connection error.

In the response from repetier host, the tmc error has gone away.

In tft mode, you’re getting no printer attached, which is most likely that the baud rate in the screen needs to be set to 250k.

But, I would advise you to go back to marlin mode for now. The tft mode isn’t as reliable as marlin mode. I think the tmc error will go away. I’m not sure what caused it, but the repetier host printout shows they are fine. In marlin mode, you can click the wheel to get to the menu.

Thanks jeffe. I wasnt able to help anymore. I was just searching tmc errror

It is correct in Marlin mode it is working fine I can move the motors. Thank you very much. I have the table ready, I just need to buy the steel tube and start to assemble lowrider2. Once I have assembled if any doubt arises again, I will bother them again. Thank you very much.
