Well… I did something stupid. I was trying to move the stop in the other way, So I tired to bridge the stop on the ramps to trigger, and now my lcd looks like this…
Don’t feel bad i have done the same exact thing. I jumped the positive on accident, I thought I knew the ramps like the back of my hand… negative and signal, negative and signal.
I haven’t bought any from amazon. Most should be fine though. I think most of the complaints about them are BS, but you never know.
I have a hot air soldering station due to arrive so I can do some repairs. I have a ton of 5v regulator fried megas that need a quick fix. but I’m sure it will be a while before I have any refurbs ready to sell.
