RE: Mk4 screen goes blank after some time
Ugh. Looks like I might have the same problem. New MK4S Pre-assembled. 🙁
RE: Mk4 screen goes blank after some time
Hi,
No Wonder. It was just a matter of time before the first MK4S showed this issue (a look at the MK4S kit assembly manual reveals that they did not change anything on xLCD display cable installation procedure).
Improving to the MK4S Prusa was only interested by making money (Who needs NFC on a 3d printer ? A display that works efficiently is what people need !).
Solving complex technical issues seems not to be their priority.
RE: Mk4 screen goes blank after some time
Hi, don t be so hard. They have very good mechanical and software engineer. But not very aware of electromagnetic. They are replacing displays, but rhe problem’is only the ribon cable. Short solution is simply to separate individual cables or shield. Long terme is stopping using parallel communication between module and use serial. // bus must be shielded… and in modern electronic only used on motherboard.
RE: Mk4 screen goes blank after some time
Hi Lucas Quigna,
It's not to hard, it's realistic.
Simply replacing displays and ribbon cables, instead of sending properly shielded ribbon cables, to those who complain about this issue is not realy customer oriented.
Recognizing his mistakes and deal with the consequences is customer oriented.
Proposing an MK4 to MK4S upgrade (keeping the non-shielded ribbon cable), for 109 Euros, seems more profit oriented.
RE: Mk4 screen goes blank after some time
I created this topic and want to tell you about my solution:
1. They sent me a new cable, after replacing it nothing changed, the problem remained.
2. They sent me a new display and another cable. But by the time I received it, the problem had solved itself and has not recurred in a year. The problem went away after printing with PETG plastic. I think that the power supply simply needed a higher load.
RE: Mk4 screen goes blank after some time
I have also (had) issues with my LCD. I have just chatted with the support team. After many suggestions they asked me to boot the printer with the LCD outside its cover. That seems to have done the trick. Apparently the LCD or the board its mounted on is very sensitive to "bending". Try to loosen up the screws holding the LCD cover together.
