Pet+ as a good alternative to ABS

[RobH2]

Great feedback. Firstly, boats. I hate them and love them, but, love them more. I have become a marine mechanic out of necessity. I actually delivered a sailboat up the Chesapeake Bay today. It was nice to get out. We've had such a horrific winter. Viking makes some nice large motor yachts. I like how clean and minimalistic the designs are. I can imagine how #1 was a result of #2. I do sailboats and can't get on the water enough and luckily I only have one.

I read on another forum to NOT use a fan so I'll try your suggestion TO use a fan. My extrusion feed is perfect. If I extrude 20mm of filament, it moves 20.03mm. I think that's close enough so I'll need to look at other causes of blobs. I'll also check my nozzle height so I can smush that first layer in a bit more. It might have risen a bit. I'll go back to a simple calibration model like you mention. I was jumping the gun. I actually did print one of my favorite torture/calibration tests first and it looked pretty good. You can see the retraction is off but for the most part the layers look good and the little 6mm diameter towers look good except for the retraction bits.

I'll do a new print now and copy your settings as a starting point. I've also posted the same torture test from the same machine with black ABS. So, you can see the machine is capable of very clean prints.

What slicer are you using? I haven't see 'coasting distance' in any of the ones I use (Slic3r, Cura, Kisslicer).
