Engineering Projects/MakerBot Improvement/printhead improvement
Appearance
Problem
[edit | edit source]Printhead is knocking over tall objects, is clipping small pieces shooting them out of the makerbot. This is with rafts and support.
-
picture of Replicator 2 printing a bracelet ... can see two green pieces of the bracelet that were knocked off

Another picture of the pieces the Replicator 2 knocked off
-
can see the big ring of the actual bracelet with all the small tiny rings around it (about 30%) done at the moment
Here are three video's showing the printhead moving, did not capture any clicking noises. video1, video2,video 3
Implement
[edit | edit source]A Spring Loaded, constant pressure on the PLA may improve the printing. Need a hardware kit.
Theory of Operation
[edit | edit source]Looks like the stepper motor has plenty of pulling power, and that this device actually creates more friction, makes the stepper motor pull even harder, but the result is a constant tension above the stepper motor, which should lead to more constant pressure pushing the PLA through the heated nozzle.
