extruder upgrade hitting back of gear.


Recommended Posts

Posted · extruder upgrade hitting back of gear.

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.

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
