Hesine M505 (China Prusa I3 copy) - how to config LCD in Marlin?

Hi all!

I bought Hesine M505 (Prusa I3), Melzi 2.0 board and strange LCD screen 20x4 with 5 buttons.
I can't configure Marlin to work with this LCD. Strange two white lines on this LCD and no more text. But i can connect with printer using Repetier-Host and i can control exitruder and move them.

Can anyone help me with configuration Marlin for this strange LCD?

I am having the same problem as you. I tried to update the firmware to a "working update" from someone on Thingiverse and the screen is now solid blue with white bars.

I came across a forum with a solution for the 5 button LCD. Someone made this firmware: [www.dropbox.com]

It works for the LCD display but it's not printing properly anymore. I think the configuration of the machine is totally different. I'm not an expert but I think the ZAXIS_STEPS_PER_MM is set wrong for our machine (Anet A8-B by Hesine)

Hope this gets us in the right direction.

Someone from another forum - P802M posted this info. This might help.

The leadscrew Zonestar3D has was pitch 2mm but number of start is 4 that mean its pitch = 4*2 = 8mm so step is 400
Some use the leadscrew that pitch 2mm too but number of start is 1 that mean its pitch = 2*1 = 2mm so step is 1600

The GT2 Pully is 16 tooth so step is 100,
Some use GT2 20 tooths so step is 80
