I like the way you routed the belts and the tensioning using the adjustable pulleys in the motor mounts. Very nice, except that it's an awful lot of pulleys for the motors to have to bend those belts around. It looks like you're using steel core belts. I suspect the pulleys are too small and that will lead to the steel cables inside the belts breaking. Then the belts will stretch in the areas where the cables are broken and that will cause all sorts of mysterious problems with print quality. Maybe the cores are already broken?
The config file and the over-ride file look fine (I just looked at them for the stuff that controls the motion- there could be other problems). The config file used to have a parameter that controlled the pulse duration to the stepper divers, but they seem to have taken that out. I wonder if there is some problem with the pulses being too short for the external drivers/cables to them.
I'm not a big fan of config-overrides. I'd suggest putting whatever is in there into the main config file and deleting the over-ride file, once you have all the settings worked out.

Also the brackets for the idlers look like they could suffer from layer separation one day. Is there a chance to change print orentation?

Nice bracket designs! What material are you printing them from, plain PLA?

I second O_lampe's comment on the layer separation. They would be strongest if printed in the orientation they are mounted. You would also get a tighter tolerance hole to mount the idlers.
What diameter Z lead screws are you using? They look beefy.
