TFT 35 v2 won't connect #60

Closed Hobhub closed 4 years ago

Hobhub commented 4 years ago

currently, I am getting no printer attached messages I am plugged into the TFT slot on the mainboard and the rs232 slot on the screen.

Modredo commented 4 years ago

same here, the text disappears after a few moments but nothing I press on the screen does anything. Its like its stuck on the main menu. Connecting to Pronterface shows the board is alive and controllable via USB connection.

Edit: What worked was uploadidng a preconfigured bin file and icons from git after a system restart. As of today, compiling works but only if I restart VSCode, sometimes windows. Good enough. Woorks great when using linux to compile.

I have been in contact with BigTreeTech and after posting a video with my problems they suggested to check for shorts from RX to ground, and TX to ground.

wiring is listed here: https://github.com/bigtreetech/BIGTREETECH-TFT35-V2.0/blob/master/TFT3.5-V2.0%20manual.pdf

i have the SKR mini E3 board, where do i connect it and what direction? the diagram dose not show where and how...

Hobhub commented 4 years ago

this is the pin diagram for the mini E3 v1.2 https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/hardware/BTT%20SKR%20MINI%20E3%20V1.2/BTT%20SKR%20MINI%20E3%20V1.2PIN.pdf

there is a port labelled TFT this is what you should plug into. On the cable, the single connector should be the 5v use that to orient it. wiring

yes it is now, trying to figure out how to add the BL touch now... if you have any ideas on that would be helpful

Hobhub commented 4 years ago

I have had troubles too because on version 1.2 of the board they changed the pin layout for the BlTouch watch this video it explains this. https://www.youtube.com/watch?v=ikHhzOIlHPg

Hobhub commented 4 years ago

this is my compiled version of marlin with bltouch enabled (you will need to change z_probe offsets because I am using a hero me fan duct) https://drive.google.com/file/d/15o6qMwFXJAuUR8rzoibim3WETKbNvUNn/view?usp=sharing

i also have the Hero me fan duct... how to i use the bin file? i apologize but I'm new to programing and still learning but this will work perfect for me, should i just cut and paste to an sd card and insert and turn it on?

Hobhub commented 4 years ago

yes just put it on the micro sd card and plug it into the printer mainboard then boot up. You might have to adjust the z_probe Z offset to get your level right but what I've set should work.

Also on my TFT35 BigTreeTech reckons it's a defect and are sending me a new one for free, so props to them.
