Octoprint with Pi 4 and Hyperpixel 4.0: Display shift

Get Help Electronics
1

I am using the Octoprint (OctoPrint 1.4.2, Python 3.7.3, OctoPi 0.17.0) on a Raspberry Pi 4 with a 4" Hyperpixel 4.0 display on my Prusa Mk3s.

Everything is fine at the beginning, the display is perfectly aligned on the screen. After printing some time the display shifts to the right so that the left side of the screen is blank and the right side is moved out of the display and can not be used any more:

It is reproducible and happens on every print. To be honest, I am not so familar with the Raspberry Pi and I do not know how to fix it. Any ideas. Would appreciate any help. Thank you.

I am having the exact same problem as @elmar2001 and this is my versions:

  • OctoPrint 1.4.2
  • Python 2.7.16
  • OctoPi 0.17.0

Used Chris Riley's video to get this done on my prusa i3 mk3s with a Raspberry Pi 3b+ & HyperPixel 4.0

Have tried changing the sudo nano /boot/config.txt with:

#uncomment the following to adjust overscan. Use positive numbers if console
#goes off screen, and negative if there is too much border
overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

&
sudo nano /etc/octoscreen/config

but this has not helped.

I am suffering from the same issue. Anybody has found a solution yet?

Ditto, I have the exact same issue.

I too had this issue. Apparently its caused by a too long file name. Using shorter names for my gcode files worked for me. A fix may be on the way.

Hi, I love your screencover.
Got the same specs. Pi4 with the hyperpixel 4" display.

I would like to print it too, do you have the stl files still or can you give me a link where to get the files from?
