Printer doesn't work after latest Prusa Slicer update?

I haven't used my Prusa MK3 for a couple of months.

I wanted to print something the other day so I loaded up Prusa Slicer. The slicer notified me of an update so I let it do that. It's been a while since it last updated.

After I sliced the object I sent it to the printer. As soon as it gets to the printer this is what the printer does:

Before I send the print job to the printer the screen does show the normal screen. It's just when it recognizes the print job that it starts to flash the screen like that. The print never actually starts either.

Does anyone know whats going on and how to fix this?

I can simply power cycle the printer and it goes back to the normal screen, but as soon as I try starting the print job again the screen starts flashing.

Try printing gcode that worked previously. If you can't find anything, download and try the samples from Prusa.

I just attempted that and same flashing screen issue, unfortunately. I tried printing off a gcode file that I successfully printed off a good year or so ago.

I rather suspect a defect on the printer. Normally a slicer update should not change anything in the Gcode start and end print settings.

Have you changed anything on the hardwre? Are the LCD cables connected properly?
I would also test it again with a Prusa template.

good luck!

wbr,

Karl

The printer has been untouched for the past few months, as I haven't printed anything at all recently.

I just tried loading Prusa's treefrog file onto the SD card and I'm getting the same error with that, unfortunately.

Try to use a different SD card.

Same issue.

I actually just tried to simply use the "pre-heat" on the printer screen and I'm also getting the same thing there. Hm.

Do you have a multimeter and can you check the voltage of the power supply? What is displayed on the LCD?

To be on the safe side, I would check the plug contacts on the printer board for corrosion, loose contacts and also the voltage-carrying wires for short circuits.
The internal resistance of the heating cartridge should be approx. 14.4 ohms and that of the heating bed approx. 4 ohms.

RE: Printer doesn't work after latest Prusa Slicer update?

I had different issue with latest update. Just after change of firmware when I tried to prepare to print PLA printer was making reset. I made all calibration etc but it was the same all the time, so I've download previous version of firmware:

https://cdn.prusa3d.com/downloads/firmware/prusa3d_fw_3_10_0_MK3S_1_0_6_MMU2S.zip#_ga=2.64371629.349009632.1623577855-1265665550.1623577855

and now its ok.
