OK, I found one, the version numbers in the configuration.h and configuration.adv.h for the A10M in the example files are; #define CONFIGURATION_H_VERSION 02000902. I think they should be, #define CONFIGURATION_H_VERSION 02000901. They don't work with the 2 but do with the 1. Now I just have to clea...

I'm about to flash the latest Bugfix 2.0.X to my GT2560 v4.1b.

Has anyone done this recently, have any problems or have any tips?

That looks like under-extrusion. I might confirm there's no obstructions in the hotend. I once had some a piece of hardened filament half clogging a nozzle that looked like that, so maybe further up in the head?

I just bought am A10M off eBay, still tweaking it in.
