I recently purchased the JIETAI Metal J-head V2.0 Delta Rostock Bowden extruder & cooling fan on ebay from Tenovo2010

The filament keeps on jamming in the in the stainless steel feed pipe. The feed gets to hot even the fan running at 100%. I've tried different temperature settings ( 180 deg c to 235 deg c). The results are always the same the filament always melts in the feed pipe before reaching the nozzle.

Hi
Please clean the extuder, and then keep the cooling fan poweroff when using. Let us know the result and we are desired to if we have given your an effective advice.

I have thoroughly cleaned numerous times so that I could try the different heat setting as per my posting. The fan is always set at 100%.
The issue is that filament starts getting soft before the nozzle, the design of the nozzle does not provide enough insulation to prevent this.

Could you please send us some pictures of your J-head and let us know more detail about it ?
