ENDER 3 stock LCD NOT working, NO power LED #1

Closed jarjartee closed 5 years ago

jarjartee commented 5 years ago

Just received my Gen L board , flashed firmware in Arduino - all works apart from when connecting to power from 24V PSU - NO LED but fans are going. Tried 2 different tutorials to get LCD working BUT NOGO

pattonwebz commented 5 years ago

I had to flip my display ribbon upside down on screen side (and cut the tab so it could go in the wrong way) to get it to work.

jarjartee commented 5 years ago

Tried all that , problem is NO power LED when connecting to 24v which indicates a problem 6CC5792C-4586-4EAD-9309-47EFF55C8799 somewhere - USB connection is fine on its own but does NOT WORK whilst hooked up to power.

Sorry I misunderstood your issue originally. I don't know anything to help with your current problem sadly :(

(sidenote: I have my endstops wired the other way. GND - D pin. I see yours are wired 5V - GND. Maybe that's a power sink? Just a though)

thisiskeithb commented 5 years ago

The current pins file in this repo is not setup for the Ender-3 display (CR10_STOCKDISPLAY), but look for SGEN-L + multiple LCD support in the main Marlin repo soon!

jarjartee commented 5 years ago

Patton - YOUR're a STAR - swapping the end stops did the trick - there's life in the display now as well BUT not quite right configured - thanks Keith

Here's a link to the PR in Marlin's repo with Ender-3/CR10_STOCKDISPLAY (and several others) support: https://github.com/MarlinFirmware/Marlin/pull/14411

Happy to have helped and I am glad you shared that picture so we could figure out what was up :)

thisiskeithb commented 5 years ago

@jarjartee: The SGEN-L is now supported upstream in Marlin, so give it a test.

pattonwebz commented 5 years ago

@thisiskeithb with the new changes do you think that will mean all of us that flipped our cables will need to flip them back round too? I guess it will bit figured I'd ask if you know since I'm unlikely to do any flashing of an updated marlin anytime this week.

thisiskeithb commented 5 years ago

You'll have to continue to rotate your cables on MKS boards.

pattonwebz commented 5 years ago

Good that I asked then before trying. Keeping cable flipped suits me fine. Thanks for the info :)
