Lcd only showing 2×20

[Anonymous]

Hello!
I started assembly last night and I’m having trouble with my display. It seems like the third and fourth lines are overwriting the first and second ones. Here are three images

What can I do to fix this?
Thank you

I realize I left a lot of assumptions in the first post.

It is a makelangelo 3.0 kit
I uploaded the arduino sketch.
It exists across restarts
at lcd startup it has lines 1 and 3 (?) written in blocks, where I expected 1 through 4.

if the screen is simply faulty, can anyone describe the menu structure so I could try to navigate it blind?
How important is the lcd as well?

I don’t know what caused it, but I poked around in the arduino ide for a bit, toggled some lcd lines and then reuploaded a fresh copy.

Now it works. I’m not complaining.

Wow. I’ve never seen that one before! So a fresh firmware upload fixed it?

Thank you for your follow up on this.

Hi There,

I just built a v3.0 kit as well and my LCD looks the exact same as the images rossD posted.

I’m not a programmer but I fooled around with the lcd & config files with little success. I also tried reinstalling both the software and board several times.

I want a normal screen too 😥

Otherwise I’m having too much fun with this thing. I’ll post some drawings I’ve done soon.

Thanks

I have not been able to reproduce the problem, which makes it very hard to debug.

Hi Matt,

I’m not sure if it helps, but I also disconnected and reconnected the two ribbon cables at around the same time. It could be hardware as opposed to software. I didn’t end up using the lcd at all in the end, preferring to run it from the laptop.
