Hello all! So I'm working on a whole load of mods for my existing Felix 1.5 Rev E. The core to these mods is a new Z-Axis system with a more centralized axis of movement, and a Dual E3D Direct-Drive Extruder, powered by a new RUMBA board. So far, progress has been mixed. The compact design of the extruder means I'm doing a lot of testing with my current setup, and work is very busy, which cuts into the time a lot. The 2 x V5 hot ends will be driven by 2 x NEMA11 Geared motors, with a trinity labs hobbed pully. The bearing wheels for them are based on a reverse-spring mechanism, which means that there will be a spring between the two arms essentially pulling them both into the hobbed pully. That's proving to be the most difficult bit to work out, but I'm making good progress on them over the last few days. I'm hoping to get all the extruder done, printed and assembled in the next 2 weeks, although I won't be wiring it up till i get the new Z axis done first. However, for those interested, the extruder progress as follows: I've done some successful test prints in PLA of the motor brackets, and the airduct, but the next thing is to get the base, bearing arms and the lock for the hot ends done. Hopefully have some new progress parts done by mid next week.
