Rostock Max (Delta) - E3D v6 Mount and Layer Fan

thingiverse

Two things drove me to design yet another V6 mount and layer fan: 1) The absence of a compact efficient layer fan for delta printers, which I needed since I have an enclosure on my RMTv2. 2) My old bulky layer fan was woefully inadequate. It would get caught on prints and ruin hours of printing, and didn't even cool very well. I drew inspiration from the Atom 2.0 Delta printer, google it! A rather fancy delta printer! This layer fan is the second attempt, my first design had issues with the air stream being too far from the nozzle, which meant that the PLA would just look terrible. These are the fans the holder was designed around: http://www.mpja.com/5VDC-Mini-CPU-Fan/productinfo/32166%20FN/ To get an effective layer fan I had to pull in the air stream very close to the nozzle to achieve the results I wanted. On the first few layers when the fan turns on, it will lower temperatures by maybe 3 degrees. It shouldn't be any more and it doesn't cause any jamming. As you get farther from the build plate the temperatures normalize out. I have 60 hours of testing and printing with this setup (with long 15 hour prints). You must make sure the fans are seated correctly in the holders. Assembly Instructions: The collar and ring for mounting the V6 are pretty standard and straightforward. The notches are to keep your wires close and through the effector. Steps: 1) Flip the effector - smooth side facing the bed. 2) Put all wiring through the effector hole before mounting. 3) Seat fans in holder - NEED to be fully seated. Use vice grip to push fan into holder. The fans are metal, so don't need to worry about being gentle. 4) Place ring and collar mount on V6 - Collar opening facing toward z arm (backwards). 5) Hook up all wiring if you haven't already done so. 6) Re-calibrate bed level with new nozzle height. 7) In your slicer set min fan speed to 35% and max to 100%. Print Settings Printer Brand: Rostock MAX BYOL Printer: Rafts: No Supports: No Resolution: 200 Infill: .2 - .5 Notes: I printed in ABS, because I needed/didn't have a layer fan for PLA. Should be able to print in PLA without issue, the mount and layer fan holder aren't touching or near any hot zones. Connect the laptop fans in parallel to a single 12v fan line on your printer.
