I've been testing the printer the last few weeks and I think I have it dialed down now, today I seem to have arrived to the correct settings to prevent stringing/globing and I can say that the print quality is excellent.

I ran a test to get the right retraction length and speed settings and 4mm at 40mm/s works pretty well, I'm quite happy with the way the extruder works and I'll be uploading the STLs as soon as I organize them.
Here's the test I just did, 15mm high truncated pyramids, 1cm base, 0.5 at the top printed at 40mm/s and 0.2 layer height; have to zoom in really close to spot the seam, let alone any oozing signs.Attachment 9519




Now I'm going to change the hotend for another E3D V6 to check what's the issue with the hotend temperature, the one I have now I have to set it up to 270 C to extrude ABS, either there's a problem with the termistor, the wiring or something else.
