Update 24-10-2017.
Hey guys.
Time for an update.
I must apologize for the delay in updates, but I've had some serious issues with my printer, as will be shown below.
As you can see, my print quality has started to go down hill, here the crotch for the midsection:
Here is another part from the midsection, here you can see the supports being affected by an excessive amount of stringing: (The hair like mess in the back)
Here's the midsection completed. You may notice some layer separations:
New back of the neck, scaled in a more correct size:
Taking a closer look, you can clearly see the layers have separated during printing:
Hip joints, not so demanding for the printer, until bridging is needed, you can see here as well it failed miserably:
And here:
And this:
Now at this point I was starting to get a bit frustrated. I'd at this point disassembled the extruder maybe 10 times, looking for clogs, misalignment of the extruder, changing the extruder gear, changing the thermistor inside the hotend, changed the filament, thinking moisture might be the cause... I'd changed and tested A LOT of different retraction and temperature settings in the slicer, but nothing made a difference.
Running more tests and trying to figure out what was wrong but testing with a 3DBenchy, again epic fail. At this point I noticed excessive oozing from the nozzle and was certain that this had something to do with it.
Tried a string test:
I now started to suspect the firmware in the printer itself, maybe something had gone horribly wrong, since I knew I was using unoriginal beta versions of a different firmware. I formatted the LCD, and uploaded new firmware to both the printer boards and LCD.
After the firmware update I did a new string test, which was somewhat improved:
Then did some more Benchies, ALL FAILED!
Now going back to try and figure out why the hotend was oozing like crazy I had a bad feeling that the stepper motor was broken. I disassembled the motor and lubricated the bearings and cleaned out everything not supposed to be there.
This gave me a result I hadn't had for days, but unfortunately still some layer separation at the top:
At this point the printer was starting to make strange clicking noises as well, giving me reason to believe that something was now wrong with the gear and that it wasn't gripping the filament as it should thereby causing the clicking noises. I noticed very small fractures of filament between the gear bladed. It took 3 days of non-stop tinkering with the slicer,firmware and extruder, just to realize that the lever pulley was worn down causing the filament to bend inside the extruder, making the gear slip it's grip and grind the filament instead of biting in to it like it was supposed to!
I did the only rational thing possible! I printed a new lever:
Which resulted in no more layer separation or strange clicking sounds:
I am now up and running again and will post more pictures of the suit as I get more parts done.
Now while it's working again, I am throwing my energy at adding a remote controlled feature to the helmet, so I no longer have to use a button switch to open and close the faceplate:
I hope you approve and thanks for looking
