    What did you drill out to make your ninja flex tube fit? I made a mistake and drilled the filament clamp so I could use a longer support tube be which was fine until I removed the tube then my filament would walk and I had to run at 20-35mm/s to print anew one to get me back to speed

    I drilled the carriage mount from the bottom, didn't drill the filament clamp. The PTFE tube doesn't fit in the filament clamp groove, but I chopped that tube off to down below the hobbled bolt for now anyway.

    Pulled it all apart, put new PTFE tube in. Seems to be a feed issue still. Problems are still happening under-extruding. Ordered a couple new nozzles..maybe my nozzle is bunged up I'm not sure at this point. Or a drive wheel is slipping? not sure how that could be.

    It turned out this entire time my problem was due to me not plugging the ramps board fan back in correctly ( I had it only plugged into 1 pin on accident )

    OOPS! That seems to have been causing the extruder motor to stop randomly, and also the Z axis would sometimes stop. All good now!

    The fan wire is so short its hard to get my fingers in there to plug it in and close the case so i missed the plug i guess, and only got it on one pin.

    I might have to solder some longer wires on that fan lead. :)

    You can simply use some crimp splices if that is easier, it is only a small fan.
    That was what we used on the last R1 we worked on. It really helps to extend it so you can open the silly thing without disconnecting the fan.

    Soldering is easy enough. Those crimp things suck.. like the ones on the Z stop switches the wires fell out of two of mine, i ended up soldering the wires into the crimp thing and heatshrinked them. they still slide onto the tabs but the wires ain't coming out now.

    You are doing it wrong ;)

    Solder splicing is always better than a crimp connection, but for that small gauge, no-stress wire a crimp will work.

    I have to admit I havnt had a crimp fall out yet... But I also don't have the fancy tools :) pair of needle pliers is my crimping tool of choice...if worse comes to worse I have a larger gage crimped that works ok as long as I'm careful

    Tin the wire and use a real crimp tool and you will not have a failure.
    Seriously though than is such a small gauge, no stress wire that twisting it together and using electrical tape would probably work
    ;)

    They are very well made crimpers. perfect for all those small crimps used in consumer electronics and PC's.
