That bed clearance is screaming for help. That first layer it’s fugly
@Felix_Garcia_Chaco What do you mean? Nozzle too high or too low?
Nozzle is to high from bed. Clearance being too much. There’s not enough “squeeze” from first layer into the bed. Then the second layer seen on the gaps are too “round”.
@Felix_Garcia_Chaco Right, got you. Ok, I’ll look at the probe offset as well.
what I see is the filament is dropping off the overhangs from too much heat retained after it is extruded, more air, less heat, slower speed and maybe less extrusion ratio. I would like to see your ‘proper part cooler’ setup, I would suggest more airflow on a bowden since they do not like resistance from low temp extrusion in the hotend, but you say you just did that. Still, let us see the printer and the prints in better detail/more angles. start with just dropping the temp. suggest a multi temp simple test print. dropping 2C degrees temp every 5mm on a 30mm+ tall angled tower, around 55d angle overhang which an OK tuned setup should print easily. BenchyMcBoatface is more of a show off after tuning, takes too long and is too complex to isolate issues, simple geometry designed to test one or two things at a time is more effective. Test print model should be like a 5 minute print at most that tests exactly the issue you are trying to see and evaluate.
Looking at the one I use, still wastes a bunch of time and filament printing areas that are not diagnostic. If I CAD an improved one soon I will post it, got a few other pressing things to do first though.
@AlohaMilton Thanks, yeah I only started benchy because I thought it was better after the extruder. I’d need to edit the gcode manually to insert the temp drops I guess? A slic3r won’t do that for me?
Something like this? Doesn’t lean, but has inner overhangs http://www.thingiverse.com/thing:923348
@Paul_Murphy yeah that looks pretty good, maybe a little tall and complex as its going to seriously test retraction with the small details retracting and then extruding over the same small section of filament a few times, that is a torture test for a bowden.
Here is the one I made for specific issue I wanted to test but may work ok for you.
It tests a few simple things, light retraction test when its making the overhangs but it prints enough inbetween that the retractions do not overlap and grind through easily even with longer bowden retraction settings 5mm+. So this will test your temps and overhangs to 45, 51, 59 and 62 degrees without dragging other issues into the equation until you are ready to deal with them. If you can print the 62 degree angle and it bridges cleanly after your tuned better than me I get a little hanging and noodling on the bridge after the 62 degree, but my Benchys are fairly clean for an all printed parts delta.
Keep it simple, test one thing at a time, you will get it sorted out in no time at all.
Since your friends with Jeb and Bob and Bill and Val, I am more than willing to help however I can :o)
I once made a 3km drill pipe, from a drill ship, trying to reach the bottom of Kerbin’s ocean with a physical object… I had to shelve that project until 64bit it was like 2 frames a minute drilling operation at the end, never got there :o(
that’s made it in game, every section having 3 kerbals doing different tasks using KIS CAS and infernal robotics to attach sections of I beams… no inventory hacks just a big ship and a lot of container storage space, 3 km worth… trying to reach the ocean floor at a deep point a few hundred KM offshore from KSP. Kerbals are amazing little buggers with their crazy notions of what is fun 
And KSP is an endless game, I am 1200 hours in and still haven’t explored gameplay changing mods (KIS, IR etc). I am pretty much stock with a few visual and usability enhancements.
That is an interesting test thing, I can’t get the 3d view where I am now, so I’ll look when I get back home.
My bowden is around 50cm long - is 5mm a good retraction setting for that length?
Spaghetti!
