3.6.16 Update

Overall Effector Update:




      Here is an update to the Kinematic attachments to the effector. Previously, the white kinematic attachments were way too short which affected the stability, but increased the load capacity. As that was not necessary, a steeper angle is the better option as stability in the effector is far more important than load capacity for a bowden extruder design. The current iteration of the Maxwell Kinematic system with the split Vee design and Nd magnets has shown to be very repeatable.

      As I designed the effector to allow the magnets to sit inside the effector, and the Split Vee kinematic mount is screwed above it. This also means that the magnetic field is apparently below the effector, and is there so that blower fan/LED ring/ IR sensor / shroud can be magnetically attached. Above is a GIF of the effector holding up a screwdriver to show the magnetic effects. With 3 magnets in conjunction, the magnetic effect is actually quite strong.




  Just an example of the Kraken sitting inside the effector. Ignore the wiring, it's not great at the moment...



    This is the all new and improved Kossel Extender, It simply just wraps around the bottom vertices. It looks simple because it is. The old design (seen below) was designed too large and was in fact just getting too unwieldy to print. It was wasting practice, and had an unnecessary hole for wiring, but in fact, the entire thing just needed to be redesigned. So this iteration just has the main attachment and then the large spacers (100mm) for my printer are just added onto it. This also allows it to be more applicable to more printers as just the extenders have to be scaled without affecting the main attachment piece.
