Thanks for the quick response. Nice to know it is not just me. No sense having slots in the extruder bracket if the only way to mount the motor is HARD against the outside limit. It is obvious that the either the top slot is misplaced or the quality of the gears provided in the MakerFarm kit is very low. Kind of ironic that they are gears made by 3d for 3d. Hope this is not a sign. Not willing to deal with feed issues until gears wear in... pulling apart to file and clean the gears. Job one after my first good test print will be to make and replace all kit parts. Not happy. MTF
