Welcome to the SeeMeCNC Community

Success! So, I took the J-head entirely off of the Eztruder and gently pushed all of the ABS out with an allen wrench while still heated up. So, it could have been an obstruction in the J-head or, which I hope is not the case, I have to do this every-time I wanna load Ninjaflex into the J-head, thus ...

Ordbot Hadron.

I think I'm getting it, the ninjaflex, to drive through. I just got a nasty little burn on my hand from the hot-end. Updates soon.

I don't have a Bowden tube, also there is not a visible 1" space between the ezstruder and the top of my J-head, there is only a couple of centimeters between the top of the J-head and the bottom of the ezstruder. Im taking off the front black faceplate of the Eztruder and going to try and manually ...

Updates, but not extruding yet. I got the hotend up to 220C and extruded 100mm of abs as suggested and retracted 20mm to remove the ABS. Then I fed the Ninjaflex down into the EzStruder. The tip of the Ninjaflex makes it to the top of the hotend (maybe getting inside a few mm) then it starts binding ...

Clarification - that was assuming you were using the stock SeeMeCNC hot end, sorry I didn't pay attention that your hot end may not have PTFE! On the J-head, SeeMe extruders, there is a short length of PTFE inside the hot end that runs down into the nozzle. The path may be "clear" but if there is ...

Channel83, something is not right! Can we backup and try a few things to get going: What size nozzle are you using? Try to use a larger (.4mm or larger) nozzle for these tests. If you have some ABS, load it up and feed about 100mm through the hot end at 220°C in Repetier Host "extrude" button. This ...

Have you tried hand feeding/guiding the filament into the hot end until it extrudes? And then let the Ezstruder take over. I haven't tried flexible yet, but I would assume(like Michael says) lots of experimentation may be necessary. I would turn down all the extrusion settings in a slicer so the Ez ...

I'm printing a spider in 1.75mm white right now. On my Max with EZStruder and SeeMeCNC hot end. This is my first attempt with NinjaFlex. I am printing on glass (no heat) at 215°C .5mm nozzle. I am getting a lot of "popping" noises and the first layer had 1-2cm long gaps. Tried lowering the temp but ...

Has anyone successfully ran and printed with 1.75mm Ninja Flex TPE filament through their SeeMeCNC EZ Struder? I'm using a Printrbot J-head, but the EZ struder drive cant push the TPE filament through the nozzle, it just ends up slipping out below the hobbed gear eventually jamming the extruder ...
