Screen offset issue - Reprap discount full graphic smart controller I've been having an issue with my screen on my Reprap, it's more of an annoyance than an issue really. After a few minutes of operation the screen will kinda shift over to the left, with the cut off part wrapping around to the right. I've attached a picture of this. I have no idea what is causing it, fairly sure it's not marlin as I've used a few different versions with the same result. My guess is that it's a problem with my cheap hardware. Any suggestions for solving this are welcome :) https://reprap.org/forum/read.php?4,838892,838892#msg-838892 Tue, 14 Apr 2026 04:39:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,838892,841064#msg-841064 Re: Screen offset issue - Reprap discount full graphic smart controller https://reprap.org/forum/read.php?4,838892,841064#msg-841064

Problem not yet solved?
Is this problem with marlin software, version RC7?

Try this:

Find U8GLIB_ST7920_128X64_RRD u8g(0);
you should find it in tab ultralcd_impl_DOGM.h
make backup (type // in front) and type on new line
U8GLIB_ST7920_128X64_1X u8g(23,17,16);

Compile and Upload

Worked perfectly, thank you so much]]> _matt_ Reprappers Tue, 11 Dec 2018 13:10:36 -0500 https://reprap.org/forum/read.php?4,838892,840108#msg-840108 Re: Screen offset issue - Reprap discount full graphic smart controller https://reprap.org/forum/read.php?4,838892,840108#msg-840108 Is this problem with marlin software, version RC7?

If you happen to have a repeatable mis-function, it's likely it misinterprets one command or even ignores it.]]> o_lampe Reprappers Sun, 18 Nov 2018 22:56:01 -0500 https://reprap.org/forum/read.php?4,838892,838915#msg-838915 Re: Screen offset issue - Reprap discount full graphic smart controller https://reprap.org/forum/read.php?4,838892,838915#msg-838915 Number_5 Reprappers Sun, 18 Nov 2018 20:14:38 -0500 https://reprap.org/forum/read.php?4,838892,838892#msg-838892 Screen offset issue - Reprap discount full graphic smart controller https://reprap.org/forum/read.php?4,838892,838892#msg-838892
