yesterday for the first time in a year i connected my printer and wanted to calibrate (i moved houses so it got knocked around a bit) but the build plate didnt move when going to the next points (tried all 9)
i did move when initializing
then i found the cpu utility and saw update rom so i searched for roms and found the following
so i downloaded the mk2 extended rom and flashed it but now my printer is unresponsive to the initialize button on the printer and it doesnt show up in the software (and not the cpu utility either)
any ideas if i can reset or reflash the cpu somehow? ive got arduinos to do something
yeah they told me to just buy new cpu, which sounds weird to me, power users should be able to reflash with for example arduino (or something similar) to fix a 50 euro board (it’s just software on the board which is messed up I guess)
Yeah, that’s a tough one to have to swallow. It sounds like the flashing algorithm only allows a forward-flash …it checks if the firmware version is higher, and if so, allows the forward-flash to happen. Sounds like there is no code to allow the lower version flash to proceed. Sorry this has happened to you, maybe there should be a warning somewhere that reverse flashing is not allowed.
