@calexfr in your home directory under CEL Robox/Filaments
it’s what I do but I don’t see profiles added in Automaker.

diStudio3D@calexfr That sounds like the filament profile is of an older format and therefore not supported by the newest AutoMaker. I would suggest using Save As… to save a custom profile, and then open that profile and the one you downloaded in a plain text editor. Then you just need to copy across any temperatures/parameters as appropriate into the new style file. I’ve uploaded a current Ninjaflex profile that I have been using recently - you can try this instead.
@chrisyt thank you but that don’t work, I think I am not in the good folder.

diStudio3D@calexfr I think it’s because your files have the ‘.txt’ extension - you need to remove this, as the file extension should just be .roboxfilament. Although they are just plain text files, AutoMaker will only load those files with the correct extension.
I’ve been having a little play with NinjaFlex this evening and wanted to eject it and put it in its bag.
I hit the “Eject filament” button and the head heats up and then filament starts ejecting… then it stops.
I searched for a method to eject filament manually and came across: http://www.cel-robox.com/forums/topic/filament-loading-issue/
I followed that and didn’t get any more success.
From what I can tell, once the filament is loaded into the head (Loaded and Index are lit), running the Eject will eject about 3cm of material (maybe less) and then stops. The filament doesn’t look like it has exited the print head as I can still see it in the Bowden tube at the back of the print head.
Manually attempting to eject it with the Adjustment controls (Advanced) do nothing.
I *think* I need a gcode command to heat the head to a high enough temperature and then eject the filament.
Hopefully someone might have an idea on how to recover from this situation!
Yes - that reflect what I experienced, too. To heat the head you can use
M104 S190
(or any other temp than 190 - can’t remember what is for ninjaflex). Oh, and don’t forget to shut it down at the end with:
M104 S0
Also, I used manually to pull the filament out with
G0 E-100
(or longer - substitute -100 with -200, etc). Also, at the same time, I would literally pull the ninjaflex filament out - helping extruder along the way. If not pulled out - extruder would just squash it behind it while thinning it on the other end causing gears not to have proper grip. It is worth pushing it in a bit, heat the head extrude a cm or so, and then pull it out (with G0 E-xxx command and at the same time gently pulling it by hand).
Thanks @click, this sounds exactly what I needed to know!
I’ll try it later when I get home.
I’ll do the same as I am due to print some tyres with ninjaflex and missed setting it up yesterday - so will be ‘pushing on ninjaflex’ this evening.
BTW don’t forget using piece of bowden tube to feed it to the extruder if you are not already using it.
@click, you sir are a life saver. That worked PERFECTLY.
I did use a piece of Bowden tube when inserting it as there were two included in the DM kit I installed a few months ago and read up that they were for flexible filament loading.
Once again, thanks! I’ll have to do some research on all these G-codes.
Glad to help. At least it worked for you! Yesterday I had hard time trying to print 3:30 print (abandoned it around 10-12 layer) - first if filament wasn’t under some kind of gentle pressure after extruder (in bowden tube leading to the head) ‘loaded’ switch wouldn’t be activated. Next, after a while index wheel stopped moving along the filament and it started detecting problems and complaining ever so often.
Might try today again 🙁
My findings with Ninjaflex are the material reel needs to have as little resistance to movement as possible. Even the slightest resistance causes the material to stretch which means the encoder wheel won’t turn at the rate expected in firmware. I ended up designing a bearing loaded reel holder which has allowed me to print without any issues.
The other issue I found is that the filament detection switch would not be activated with extruder two supplied as part of the dual material kit, but works fine with extruder 1 which has the upgraded grey housing.
