OK, all back to normal again. Just did a couple of prints and my printer is listening to Cura again. Not sure what happened with the first print after rolling back firmware, but all is good. Thanks for everyone's support!

Thank you! I will check if those gcodes are in my gcode file otherwise add them manually and see how it goes.

Figured I will post an update here. I downgraded my printer firmware to Feb 2023 firmware. But, same issue, it just prints full speed! It does not seem to care about the print or accaleration settings from Cura. So this is most likely not a firmware issue some other random obscure thing I have no clue where to check...

Lol thanks @jaysenodell I appreicate you sharing this. For now I'm just reducing the speed on my printer using the screen until I get time on the weekend to fire up Octo.

Ok yeah updating the firmware again did not fix it. Sigh. Back to Googling and trying to find a solution. Otherwise this might be the swift kick that I need to switch over to Octa. I also have a Raspberry Pi 3b+ lying around looking for work.

@Slashee_the_Cow Lol I like your comment about Elon and Reddit. I found 2 posts on Reddit where people have the same issue, but they don't seem too phased about it. To be honest, the printing speed and quality is a lot better with the new firmware, even on full blast, but I like things to work the way they were intended to work. That said, I THINK I might have found a possible solution. According to a thread on Github, you have to flash the screen firmware first, and THEN the motherboard. I did it the other way around. Just finishing off a print then I will flash the motherboard again. Will keep you guys posted. Thanks for all the input!

Hi @jaysenodell I'm printing from an SD card. I've always used an SD Card, on both the old firmware that respected Cura as well as the new firmware that is not listening to Cura anymore. @Slashee_the_Cow I've considred going Octo, but I like the simplicity of the SD Card (for now). Its just strange that all other settings such as brim, top layers, etc are all still fine (by fine I mean the printer uses whatever I set in Cura), but it is just the speed and accaleration that the new firmware seems to be ignoring. I'm doing a reset (from the display attached to the printer) now, just to see if that won't fix anything. Will post my results here as an edit. Update: The reset did not work.

Hi everyone Printer: Ender 3 S1 Pro with the F401 chipset Printer Firmware: Ender-3 S1_Pro_JPN KR_HWv24S1_301_SWV2.0.8.28F4_F401_FDM_LASER (Firmware) Cura Version: 5.6.0 Today I upgraded my Ender 3 S1 Pro with the F401 chipset to the latest firmware from Creality's website. I installed the screen and motherboard firmware according to their instructions. I used my usual Cura profile to run a test print, just to make sure everything is fine, and everything turned out great. But, I then realized that after the firmware upgrade, my printer is ignoring a lot of Cura settings, especially the settings related to speed and acceleration. I proceeded to slow down my print, by a lot, so that the difference in speed will be obvious, but my printer still just prints full speed. (I tried multiple different 3d models, both bigger and smaller ones, but all with the same results). I also removed my Ender S1 Pro from Cura and added it again, just in case, but no change. I have no clue if this is firmware related or if the firmware expects "different" Gcodes now that Cura does not provide in the GCode file. I guess I can just downgrade the firmware again then everything will be fine, but I am hoping one of the community members might have some advice. I attached my Cura project file for one of my test print as well as the GCode file for the same test print. I also attached the profile that I used. Any help will be greatly appreciated.
