Has someone managed to install this?

I using Arduino 1.8.8, win 7 32 bit.
I get error message "U8glib.h: No such file or directory" when trying to upload the new firmware.

I can not get this to work.
Error message: U8glib.h: No such file or directory

I have downloaded U8glib.h and placed it among the other .h files. It wasn't included in the zip-file I downloaded first. But it does not work.

Hello max_headroom,

You need to download that library in arduino using it's library manager, see the link here

But for the B2X300 you do not need to compile the firmware on your own using arduino as we have the precompiled version available on git that can be easily flashed using Cura, see this link here: viewtopic.php?f=17&t=1595

If you have any problem using the machine or with any of the processes feel free to contact :)

Best regards
