I just recently purchased a kossel mini kit and assembled it. I tried to adjust the firmware settings to start to calibrate the head and travel and lost the lcd display when I uploaded the changes it also says there is an invalid library in c: users documents adrunio read.me txt when I do try to upload the firmware. I am using marlin 1.8.1 that is supposed to be the latest version

I was wondering if anyone else may have experienced a similar situation

I chatted with someone from work and they suggested that I download an older version of arduino so I did find the 1.06 and this did not help

I also read where I may have to download the u8glib so I did this and included it in the libraries and it was still no help

I also tried loading the u8glib manually using only it and it still gives me the invalid library note and my lcd display is still not displaying any information
