EEPROM Datasize Error for BTT E3 Turbo #45

Open ckiefer opened 2 years ago

Hi

I am using the latest code from anycubic-kad-bugfix-2.0.x to compile the firmware for target anycubic_mega_zero2_btt_e3turbo_bl_e0fan.

Without doing any changes to the Marlin code, I am getting this error when powering up the printer:

It's still working with the firmware I built a few months ago. I am sharing a zip file with the new, not-working firmware as well as the old, still working, firmware. mz_btt_e3_turbo_firmware_20220416.zip

Any help is highly appreciated. Christoph

With drastic Marlin version changes (e.g. from 2.0.9.x to bugfix-2.0.x) it might be cases that layout of EEPROM is changed and might require re-initialisation from defaults+save those defaults to eeprom (M502+M500). If you have custom calibration values, don't forget to re-apply them and do M500 again. If that doesn't fix the issue, let's have a look more in details. it might be so that something was broken in bugfix-2.0.x branch for those borads. I still need to update branches to latest 2.0.9.4/2.1 releases + rebase development on bugfix-2.1.x branch. Hopefully during vacation in the end of July I'll have more time for that.
