Ok, no idea about your printer but here is what I do with my Makergrear m2
Had to replace the OEM extruder housing with one that had been modified for TPU open spaces were tightened up to keep the filament form getting jammed.
Tension has to be very light or filament will squish and then get jammed
Nozzle size must be .5mm or larger for good results.
Speed must be 15mm no faster
retraction must be no more than .4mm (direct drive)
temp on my printer i 230 and cold bed (sticks too tight to polymide tape
Nozzle is always cleaned with esun cleaning filament before changing material and a a couple feet wroth of thread is extruded to remove cleaner or the print will not adhere.
Filament is mounted on a bearing supported gravity feed rig
filament diameter in slicer is set to 1.65 and extrusion multiplier is bumped by .1 (most every filament I use has an extrusion multiplier of .93 on my machine assuming I set the actual diameter of the filament.
Just printed some vibration dampers yesterday with no issue using the above but I use S3d to slice .
My guess is your are probably printing way to fast.. start out at 10mms and work up 2 of 3mms ..
Good luck
