um2 extruder free sample

My original extruder could no longer handle certain softer types of PLA after 1600 hours of runtime, and had underextrusion because of it which could only be solved by printing a lot slower. Now it"s like it"s new again and even better for softer PLA"s as I can print them at 50mm/s without issue, normal PLA I can now print at 70mm/s without problems. Very easy to install with the online manual from bondtechs website, it only sticks out from the side of the printer but only about 4 cm"s.

This is a lightweight Volcano Head for an Ultimaker 2 using a Volcano Hotend and a Direct drive BMG Extruder including a ADXL345 for InputShaping using Klipper.

The Linear Slides are fixed used curled M3x4 knurled nuts and M3 screws from the top and bottom of the head. The Extruder is as high to be above the case not causing any colisions.

If you go beyond this in-the-middle stage the printer tries pushing harder and harder to extrude the material but eventually the pressure will be too high. Ideally when this happens the extruder motor will do what we call a skip back where the axis of the motor spins in the opposite direction for about a quarter turn to relieve pressure. This will not damage the printer, it"s an intended behaviour to prevent the filament from being ground up by the feeder. You will hear when this happens as it will make a *tock* sound and if you look closely at the filament that is being extruded you will see a sudden reduction in volume.
