Thank you. Sorry so long in noticing your response. I do have the spring loaded plunger and still no-go. I've tried so many things. Oh well. Thanks again.
Does your rep2 have the spring loaded filament loader upgrade? We had issues with our replicator 1 loading ninjaflex, but a upgrade from the plunger loader allowed it to feed. We've also had some issues with feed gaping, best to clean out the nozzle and try to live leveling the build plate.
I love the idea, but I can't, for the life of me, get my ninjaflex to work at any setting on my Replicator 2. I can only get a few layers and then it binds up on the gear drive and spools around it. Very frustrating.

No raft or support needed.

NeoPixil ring and accelerometer lays on the back of the Flora.

Align the Flora inside the body. Use a micro pencil to mark the pin outs.

The pins of the NeoPixil are marked from the inside of the body.

Position the accelerometer in the center of the NeoPixel Ring.

Use a needle to puncture the markings and stretch out the holes.

Thread strips of 30 gauge wrapping wire through the holes.

Lengthy wires secures the Flora and the accelerometer in place while soldering.

Pull wires to the edge of the pad and bend the tip to secure the connection while soldering.

A complete circuit diagram and tutorial can be found on adafruits learning system.

JST connector will reroute the power for a compact circuit.

Solder from the on-board JST connector on the Gemma.

A slide switch will makes it easy power it on and off.

Shrink tubing secures and protects our solder connections.

The wires in the power circuit are positioned inside the body and fitted on top of the Flora.

Position NeoPixel over the wires of the accelerometer and thread the appropriate wires to the pins.

Bend down wires to secure the NeoPixil ring.

Cut the wires short, strip and solder the NeoPixel ring.

Remove any access wire from the NeoPixel ring.

Thread the Accelerometer and bend back the wires to hold the circuit in the center of the ring.

Strip, solder and remove the access wire from the accelerometer.

Reduce the length of the battery cable and heat shrink the connection.

Pop the slide switch through the cavity for a tight fit

Carefully position the battery on top of the circuit.

Align the back cover to the cut out of the slide switch

Press down on the edges of cover to protect the circuit.

USB easily plugs into to the flora to reprogram sketches.

The pins on the band snap in to securely hold the body together.

Side the switch to it on power and keep your New Years resolution while staying safe and glowy.
