3D Printing doing my head in - Help please!

[cropwell]

I printed the file that Andy fixed for me and then the printer refused to extrude evenly, to the point where prints were failing. After raising the nozzle temp to 240C, I finally got a print, but I had to do it in bits and glue them together.

The object is a nozzle for the vac, to be fixed onto the profile at the bottom of the Z axis. I have added a 10W Cob LED and heatsink (I had 3 of them left over from a job).


The offset is because there is the Z home switch target in the way, but I may be able to shift that and reprint with a full width nozzle.

Cheers,
