For some reason, when I went to hit preheat PLA, i saw that the nozzle temp wasnt coming up but the bed temp was (i had it set for 200/60 before). So i went to check the preheat pla settings and both temps are listed as 0. For PLA and ABS both.

After i entered my numbers and hit save, it would show up until i turned my printer off. When i turned it on again, it again would show 0/0 under preheat settings but it now actually went to 200/60. I vividly remember the numbers not being “0” before. It always showed my 200/60 settings.

Lastly, I am unable to factory reset. That button doesnt do anything for me. It just beeps, but nothing is actually done.

What is going on?

Can Creality provide an actual solution? It’s incredibly frustrating to have to keep setting my own preheat temps on the lcd every single time i turn on the printer.

I just tried it again with a different sd card. Same thing. It begins at 0 0 for both ABS and PLA. (This is a different card that worked fine before). I entered the new settings (200/60 and 250/100) and hit save on each. I even auto leveled again.

Then, upon turning the printer off and back on again. It is back at 0. Why is this happening? And why doesnt “restore to factory” do anything?

I’m not understanding why this works sometimes and sometimes it doesnt. I even had one time where it listed the correct preheat temps but when i actually hit preheat, the temp would stay at 0 while the bed temp heated to the correct value.

@admin this isn’t a solution for me. I never changed gcodes on my sd during the time this issue happened. Literally nothing changed during the time this switch occurred.

Nothing else was added or removed from the sd. In fact, the sd stayed in the machine the whole time.

@hansamann did you set the 4k block size? That did the trick for me

@admin yes i know the hole size. But what nozzles are compatible with this printer? Mk8? V6? I’d like to know because I’d like to order different nozzles for high temp prints.

I know that the standard nozzle that comes installed is 0.4 mm but what about the nozzles that come in the tool drawer as extra? I don’t see sizes written on them and I’m not able to find any info on them. What sizes are these?

@Stonedog03 did the same thing. Took a while to figure out how to do it on a mac but i was finally able to. And it worked! Thank you!

I updated the board firmware no problem but the screen firmware is acting odd. I’m getting the blue screen after about 2-3 sec, but it immediately says SD Card Process . . . END ! And lists the different type of files below with all of them having a number of 000 on the right.

I assume it would list the number of each of those types of files included in the screen firmware, no? I tried to redownload the file, reformat the micro sd, nothing.

Some info - i have a micro sdhc (not sdxc). Is that compatible? What else could be the reason?
