BTT TFT35 with Duet 2 Wifi

TimsWorkshop

Hi All - I've read the previous posts and have switched my TX/RX pins on my cable so that I can use my BTT, but something weird happened.

About two weeks ago when I first finishing setting everything up, I plugged in my TFT and it worked... Said printer attached. A few hours later it stopped working and not sure what caused it.

I've just used the most recent version from the BTT Github and copied over the correct files, renamed config_rrf.ini to config.ini and uploaded the new firmware... All flashed properly. But I can't get the TFT to work.

I've set the M575 command on all three options (S1/S2/S3), but neither of them work. I've also made sure the TFT Baudrate setting is 57600.

M575 P1 S1 B57600

Is there something else I'm missing?

@infidelprops
what about the wiring? Did you check Vin on the TFT? Maybe there's a voltage regulator on the TFT that died after a few hours?

@o_lampe Thanks for the quick response mate! The TFT actually works and turns on... just says no printer attached.

@infidelprops try swapping the Tx and Rx pins around... and check the speed setting in the TFT.

HTH. P.

@paulhew Thanks Paul - I've switched the cables already and made sure the speed settings were the same, but I'll give it another go now.

@infidelprops I take it you have seen this page..

You show a S1 in you M575, this shows M575 P1 S2 B57600
I appreciate you have tried all combo's.

Power off for 10 secs and back on again with the TFT connected.

Other than that, @o_lampe could be correct.

@paulhew Thanks dude and yeah, I've seen that link and have all those configured. I'll keep sussing around with it
