Extruder not working correctly after firmware upgrade

Hi all

I upgraded the firmware to v2 from the Velleman download page (Firmware_k8200_marlinV2).
Everything is working, except that no or hardly any filament is extruded.
The extruder seems to be working fine, retracts etc without problems. By manually turning the large gear the filement is extruded as usual.
Also when pressing the button in Reptier host the extruder does what it should.

Can anyone give me a hint on where to look?

Thanks

Hi all

Ok, it’s working again :slight_smile:
I uploaded the v2 firmware again, the only change I made was:
#define EEPROM_CHITCHAT

However, now I can read the EEPROM values (they were all ok), and the extruder works fine.
Strange…
