everything looks fine but NO PRINTING

Recommended Posts

So i tried to print for  3rd time and a new roblem came up with the nozzle and the pla . i followed the intructions of the moderator because i had the same problem before one week or something and  i thought i fixed it. today i send a print and it was 28% and it was still printing a really small amount of the project. the photos that follow is from the process i followed but stlli cant understand why the pla is melting around the nozzle and doesnt go out properly.

Can I see a photo of the feeder when it's closed and ready to print?  If you are new with this printer you might not be closing it properly (this is a common problem for first time users).


Is this your first time printing or have you printed 100s of parts just fine in the past?


With the nozzle at 200C and the feeder open such that the filament slides easily in and out you should push on the filament with about 5 pounds (3kg) force and see filament coming out of the nozzle.  Does it squirt out just fine?  If so the problem is at the feeder end and not the nozzle end.


If it does *not* feed well one test is to remove only the nozzle  (while hot - anywhere 120C to 180C) and then let it cool to room temperature and then feed the filament through the head to see if there is a tight spot somewhere - it should slide through easily with the nozzle removed and everything cold.  I suppose there could be some hardened left over filament in the head so maybe you have to heat the block to about 100C and that should be plenty warm enough to slide fresh filament through without making a mess.  Once it starts passing through the head lower the temp and pull out the filament - you don't want it stuck in the threads.  Then try again at temps below 50C (52C is the softening temp of pla).

this is my first printing

i put together the main piece (without the fan) so thatyou can check it out.

i heat it and pulled the pla and it didnt feed so i remove the nozzle and it was sliding normally. 

the problem is   on the nozzle

please check the photos  i send you

Sorry - this new forum isn't good about notifications.  I get too many that are duplicates and miss some among the many notifications.


Oh my - did you destroy it?  The only way to know if it works is to power it up and check the temp and if that is good to heat it up and make sure the temp rises.


I think I suggested in my post above that the problem is more likely in the feeder - did you check to see if it could pull several pounds/kg of force?  You can test this even with power off, just hold the gear with one hand and pull hard on the filament with the other.


If the feeder is fine and it looks like it's feeding without the nozzle that kind of leaves the nozzle, right?  It might be clogged.  Dust can get on the filament and take a trip through the bowden with the filament and end up clogging the nozzle tip.  This is not very common but it does happen.  You can fix that with something called a cold pull.  Read up on that and watch a video of a cold pull in action.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
