Nozzle repeatedly clogging while printing Ninjaflex TPU
Hello,
I'm having a problem printing white NinjaFlex TPU on an Airwolf3D AXIOM Dual Direct Drive printer. I am trying to run some test prints of a face mask ear strap but am having problems with the nozzle clogging shortly after the print starts (within the first 5 or so minutes). What happens is the print will start printing the first layer without a problem, but after printing the brim and the outline of the part, the nozzle starts clogging as it prints the infill for the first layer. I used the recommended profile settings on the NinjaTek product page as a guide for the settings and am using Apex (Airwolf3D’s rebranded version of Cura) for the slicer with the standard TPU profile modified with the NinjaTek settings for speeds.
So far, I have tried a deep clean of the nozzle (which was using ABS previously), and tightening the hobbled bolt in the direct drive hoping that would help. I also tried changing the Z offset from the table in case the nozzle was too close or far away from the bed. I have attached an image showing the part I tried to print, and a copy of the profile I used for the test print (you can still view the settings without having Apex). Can anyone give me some advice on what I can do to solve this issue?
Thank you!
