The glass is flat, the 4 corners all are the same distance from the nozzle (2 sheets of paper), but in the center, the nozzle is against the glass bed... that is flat... the gantry is eq...

That will come once I can ensure the hardware of the printer is working properly.. and this is where my problem with the impossible to level bed...

Turns out the steps was the problem. rather then the 2560 it should have been... it was only 50...

Good idea, I will look into it. I have printed off a set, But I will be doing some modifications to them to help make them more stable.

I'm going threw a MESS of a build, I updated to Marlin 1.1.8 and I had a steps problem. I compared it to the 1.0.2 firmware that was on it and made some edits so that things matched. They don't.. My print now looks like this: MVIMG_20190703_183602.jpg The board is an A+ board so the 1.1.8 firmware s...
