Aliens have landed
It appears an alien race is attempting to communicate with me (see attached image).
Whilst I'm honoured to be their choice of spokesman for Planet Earth, they are ruining my prints....
Any ideas what's causing this???
Print just freezes midprint and garbled message is displayed...
RE: Aliens have landed
What firmware are you running, did you recently upgrade, and if you did, did you do a firmware reset and clear storage?
RE: Aliens have landed
Firmware upgraded about four weeks ago - probably 30 prints since then with no issues.
Upgraded through prusaslicer, ie the Prusa recommended upgrade process.
RE: Aliens have landed
Looks like translation is missing. Make sure you're on most recent firmware version (english language?) and you have to flash with PrusaSlicer.

RE: Aliens have landed
Weird, everything else is fine (ie clearly installed the right language version etc) - maybe try reinstalling firmware?

RE: Aliens have landed
_SEC_LANG is an indicator for missing translation. LCD should be perfectly fine. I've seen this issue on GitHub but can't find it easy anymore.

a guide how to compile with multilanguage option (100% working with Linux Ubuntu 18.04). If you compile with Arduino IDE you must set multilanguage to 0 ("Firmware/config.h" set LANG_MODE to 0).

RE: Aliens have landed
Ah, this looks spot on - only question is I'm just using the .hex file from Prusa's site and Prusaslicer to install firmware upgrade - do I need to manually compile the firmware or something?
RE: Aliens have landed
It depends on your printer: MK2, MK3, MK3S ...with or without MMU2/S?
Download the right firmware, you do not have to change anything, just transfer it with newest PrusaSlic3r2.1.0.
Good succeed!

Also - it isn't unlikely the firmware lost it's mind due to a lightning strike in Cleveland. A full reset and data clear has restored my printer's brains after such mystery events.
RE: Aliens have landed
Cool ok, it seems to be fine apart from the garbled text, so will do a full reset and restore latest firmware - ie probably wasn't aliens after all.......but then maybe that's what the government wants you to think.......
RE: Aliens have landed
My printer only required the reset with eeprom clear; I've never needed to change firmware to regain function when this has happened to me.
RE: Aliens have landed
The plot thickens - did an eeprom 'all data' factory reset and rebooted, then started going through the calibration process and shortly after testing the y axis, the same garbled text appears.....?
Thinking this can't be firmware as suspected - any other thoughts?
RE: Aliens have landed
Random data hijacking is a sign of more serious issues.
Are you connected to anything via USB? If so, you might try leaving the USB disconnected for a while as a test.
Is there a portable heater in the vicinity, one that has only recently been turned on, especially one connected to the same power outlet or circuit? If so, unplug it for a while.
And, has there been any other changes since this started happening? New firmware, new computer or other electronic device near the printer? Any environmental changes?
The printer has no electromagnetic shielding, so any nearby device can emit fields that can affect the printer.
Also, it is winter, and humidity levels drops, static electricity fields increase. A human is a great storage device for these fields and a discharge causes a large EM spike that can get into the printer and fry it's brains. You might want to consider a ground strap for working near your printer - one connected properly to power mains / earth. Even a tap bar (like a wrist strap laid flat) near the printer to discharge yourself before touching any part of the printer; or while not ideal, make it a habit to touch the power supply case before touching any other part of the printer: at least this way the spiky discharge goes more directly to earth. I'm assuming the power supply case is at earth, but honestly can't guarantee it is so an ohm meter is needed to verify;
Just a few ideas ...
RE: Aliens have landed
ps: Here's a fairly inexpensive matte that might help ESD issues. Place it under the printer, connect the snap to earth, and just be sure to touch it first. It's something we all should be doing since the printer is wide open to ESD events.

more choices:
pps: the matte can be trimmed down, too; just leave enough area open you can easily touch it first.
RE: Aliens have landed
Hi Tim,
Lots of good ideas - have summarised, but shout if anything missed/unclear.
USB - connected to octopi - although has been for months with no problems.
Environmental
- weather has definitely shifted down to sub zero over last couple of weeks
- also have moved to new table - and most notably moved it out of its old IKEA lack enclosure (found it much too fiddly to get access)
- this has moved the PSU back to the default position (was under the table in the lack set up)
- firmware was upgraded to latest version
- no electric heaters or any other close changes
- static is an option, although the garbled text is generally happening in mid print when no one is near it - will check mats anyway as look dead handy for general electronics work!
A few posts online seemed to suggest this could be a faulty thermistor on the heatbed or hotend - does this make any sense? Can't quite see how that would garble the LCD screen?
RE: Aliens have landed
Another idea: Maybe a pin is bent here and there is a short circuit? I cut too long pins with a fine cutter and also grounded all electronic components. I assume that all cables between Einsy and LCD are fully working?

RE: Aliens have landed
I'd try down-reving the firmware as my next step.
If using the old firmware does nothing, then start looking for something loose. You did move things, and I presume you were inside the Einsy cage to change power leads. Anything (wires specifically) could have been moved or bumped and have become intermittent. Reseating the two LCD cables would be my second thing to do - and do it at both ends. Also a good time to check for places where the LCD cables rub against metal. Make sure the insulation still looks good (no bare copper showing where the cable bends around the sharp frame parts).

Hi,
did you find a solution? - I get the exact same message since two days.
When I try to print via Octoprint I get the same Message in mid-print and Octoprint Status says: "Offline (Error: Temperature heated bed switched off. MINTEMP triggered ! - // action:cancel)"
I had no issues for the last month and 200h printing. Currently I'm not able to finish one single print...
Yesterday it was possible to print from SD-Card, today even this fails. But from SD-card fail seems to be different - it simple stops and don't do anything. At the moment I try to print without USB connected. I'm not quite sure Octoprint maybe cause the problem?
My Setup:
Prusa mk3s no MMU
Firmware: 3.8.0-2684
Octoprint (1.3.12) via USB connected
