I've added a 1cm bumper to the carriage that hits the endstop switch on the y axis because I've added a fan on the backside of the extruder which needs a little extra room.
I've substracted one cm from the build volume y but now the line for cleaning the nozzle gets printed into the air in front of the build plate.
I'm not sure which of the two settings "Origin offset" or "Toolhead offset" I should change now?
