Firmware bug

I found a bug in the latest firmware released in October.  Its happened to me twice where i turn the printer on and load the same print from the SD card and it will say this g code was designed for another printer (its not it was working fine earlier and was made on prusaslicer for the i3 MK3s) and it says continue, there is no option to go back so i turn the power off.  When turning back on it tries to resume a print that was never completely loaded and gets stuck in this until i do a complete erase all settings.  Today i just managed to recreate the exact same problem with same steps as above.

 

Not sure if this is the right place to post this bug, or if the manufacturer even reads this forum?

I suspect a bad SD card

RE: Firmware bug

When the printer is in the stuck routine of trying to resume a print that was never finished i have tried removing the SD card restarting the printer and it still comes up.  I guess the problem could be trying to load a print from the SD card a little too quickly after the printer has been turned on, my suggestion would be just to add an option when it says this g code has not been made for this printer it should give you the option to cancel or continue but it only gives you the option to continue.

I honestly dont think its the SD card, it can work for days and as long as i dont load a print immediately after switching the printer on its fine but i have seen the same issue mentioned elsewhere but nobody knew what was causing it and i believe this is the cause and at the end of the day looks like a bug in the firmware, i will keep an eye out on the SD card and when time permits do some read/write tests on the card.
