Help

Just installed SKR 2 on my ender 5 but after turning it on there is only blue screen on the LED. If i connect my TFT35 it just says "printer not recognised". Constant red led light on the board. Please help.

Send wiring photos and configuration files.

when you code your firmware you have to set your com port 1 value to 0 and your baud rate to 11250 then your boards will be able to talk to each other. It took me a couple of sleepless days to figure it out myself so dont feel bad

Longonwoo commented 2 years ago

Have you tried booting it in Marlin mode? It may connect there even if your BTT screen does not

Attention! SKR2 uses port 1 for communication with TFT. In Marlin, therefore, you must define port 1 on 1. Default TFT serial port speed at 115200 (not 11250). The serial port can change to 250000 in the configuration.

Yes I know that's what the documentation states. But I had the same issue after setting it up that way. I ended up watching youtube videos to see what others had done to get the BTTtft35 to work with a BTT skr board. I was able to boot. I could link to pronterface and get the board to respond and communicate with my system. I could even boot the BTTtft35 to work in Merlin mode but I got the same error "printer not recognized" when ever I went into the graphical configuration.

I found https://www.youtube.com/watch?v=57f-sG0nFeM&t=1329s from Chris Riley and he had to set com1 to 0 to get the graphical to communicate and yes I am sorry I left a 0 off my baud rate of 112500. But once I made those changes to my firmware my system could talk between the two boards.

Just sharing my experience

I wish you all the best of luck.

radek8 commented 2 years ago

If your TFT is communicating with Marlin on port 0, then you do not have a SKR2 blanket (the ticket writer writes that he has SKR2, and this is the repository for SKR 2), but some other, such as SKR V1.3 or SKR V1.4. SKR V1.3 (1.4) use port 0. It's great that you share your experience, but you have to be precise. Otherwise, you will mislead inexperienced users.

The serial port speed is not 112500 but 115200!

DinWilliam commented 2 years ago

Thanks for all reply. Got called to work so wont be home until thursday or friday. Will try everyones responce then.

You have to wait for the attachment to save, otherwise it will not open ...

radek8 commented 2 years ago

Port 1 is OK, speed 115200. You must set a parameter in the config.ini file serial_port: P1: 6 P2: 7 P3: 0 P4: 0 save and conficg.ini save to sd card, insert card into TFT and turn on TFT.

You have a bad TFT cable connection

radek8 commented 2 years ago

DinWilliam commented 2 years ago

Yes, it works with the new cable connection. .But every guide i checked said to connect to the pins i did or i have done some bad research =S thank you for your help and thanks everyone for your time

radek8 commented 2 years ago

Probably someone posted bad information or made a bad video on Youtube. You are not the first with this mistake.
