That’s pretty normal. These bots are very susceptible to EMI, and that is a symptom. If you are running Sailfish, you can press the right button, which will reload the screen properly.
If it concerns you, you can re route all the wiring away from your LCD ribbon cable under your bot.
This is a picture of the bottom of my bot.this is pretty common.it’s something to do with shielding the cables and display i’ve heard.
it is resolved with a restart once print is done. happens to my machines about once a week randomly.
I just re-read your OP, you say you can change temps from the menu? It has been a while since I ran non sailfish firmware, but I don’t think that that is a stock feature. Some of the cloner’s pull more bits of sailfish into their code, mainly the larger then 2G SD card. You should be able to press right to refresh the screen.
I’m running sailfish. Actually, it has done this in the first print I did which originally caused me to upgrade the firmware in the first place as I was wondering if something on the rom might be corrupted.
Pressing right fixed it, thanks, didn’t know that
I’ll look into that, thanks. I’m considering some ESD shielding anyway to make sure the bot doesn’t fry down suddenly due to me touching something. It’s attracting a LOT of dust anyway to I figure the process of printing itself seems to cause a lot of static buildup by itself too.
I’m not sure if I’m happy or sad to hear that it happens to non-Sailfish machines. My machine with original firmware works perfectly. The one with Sailfish died within 1 day of upgrade. Maybe it’s just a coincidence.
So, just for your knowledge. Original firmware, is Sailfish(ish). MBI pulled sailfish’s motion planner and other items into its firmware around 7.0 The only difference is the amount of maintenance that each has received. MBI firmware is long abandoned, Sailfish 7.7 is still maintained and has addressed many bugs, both trivial and the very serious ones that could lead to disaster. did you know that original firmware wont report higher then 260C on the extruder, even in a runaway heater situation. USB printing is never recommended.
To blame sailfish on borking your board is silly and pure non-sense, Not meaning any offense( and also not being involved with your installation or troubleshooting), but 99.99% of sailfish installation problems are user generated. Myself included, I failed to follow the directions and had issue with printing in the center.
The garbled screen is a pure and simple hardware issue, neither firmware will cause or prevent it. Sailfish allows you to deal with it, by pressing the right button. Wanhao has started to insulate the ribbon cable with some sort of shielding. I have posted pics of how I have dealt with it.
Done this to me too, all I do is press the left arrow key and it returns to normal
Hi I have a problem with this screen appearing half way thorough a print, however when my screen gets garbage, my X motor starts to grind very loudly. Would this also be do to interference?
