extruder upgrade hitting back of gear.

Recommended Posts

The button head on the tensioner block of "bertha's upgrade" is pushing my big extruder gear outwards. Should I throw a 3rd washer under it. This would offset the extruder gear and the drive gear on the stepper motor. The drive gear sits a bit cock-eyed on the shaft as well so there's a spot every revolution of the motor that binds up against the extruder gear. Do these issues wear themselves in after a bit of use, or should they be taken care of now during assembly ?

The new tensioner is 5mm wider than the extruder's body. Assuming it's sitting nice and symmetrical that means it hangs out 2.5 mm on the gear side, plus another 1.5mm for the button head of the screw meaning a minimum of 4mm. Each washer's only 1.5mm, so it takes 3 washers, simple enough. What I really need is a straight gear for the drive motor, then the extrude gear wouldn't be binding up and walking all over the place.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
