Thank you for the information. Yesterday I sent an email to the support. I hope to receive some help soon. I tried to open the bottom box covering the electronic but I need also to "release" at least the left side panel.
By the way I noticed that 2 wires of the Z stepper motor are crushed between the metal box and the bottom panel.
I dont know if this may cause any issue.
Contact support. We've recently identified a problem with the cables going to the front panel, which could be causing your issue.
In the mean time, you can check the bottom of the machine. Not sure how willing you are to pull thing apart, but the cable going from the display to the main electronics should not have any loops or twists in it, this causes serious communication issues with the SD card and the display. (If you're not comfortable at checking this yourself, contact support by email, I'm sure they have more solutions they can offer then I can)
We're also making some modifications to this cable to improve it, and providing better instructions for our assembly line.
