Apparently systematic nozzle clogging
The Micro Swiss hotend uses an all metal hotend. These type of hotends are more difficult to operate considering they do not have a Teflon liner that shield the filament of heat creep. From this article: 


  Jams and clogs are often from a combination of excessive heat and
  non-optimal material flow. This effect is worsened by poorly cooled
  all-metal hot ends, high torque extruder gears, small nozzles/layers,
  slow printing speeds, too thin first layer, and excessive retraction.


The bold faced text in the quote sums up what is causing this. A smaller gear requires more force/torque as the arm i.e. the radius is smaller.

The article describes what steps you could do to alleviate the problem. Of all the suggestions, "Minimize retraction", seems a possible candidate for you to look into considering the posted print settings. As this is a heat related problem it is advised to also increase your printing speeds, these are pretty low (30 mm/s for slow and 60 mm/s for normal printing) and also check the cooling of the "cold end" (the fan that cools the radiator fins). Also reduce the printing temperature, 210 &deg;C is pretty high for PLA filament, personally I don't go over 200 &deg;C (note that this depends on your filament, but most PLA brands can be printed in the 185 - 195 &deg;C range).

You have a pretty large retraction specified. The Ultimaker default is 6.5 mm is considered to be large, but works perfectly for Ultimaker machines (read Bowden tube setup). In my Ultimaker 3E which uses all metal hotends, or, in my custom HyperCube Evolution, also Bowden, but with a lined hotend, 6.5 mm retraction works perfectly.

Please look into this answer and this answer. Both describe that the retraction performance is worse with all metal hotends. My experiences are exactly the same with metal hotends, at least the cheaper production ones (I tested cheap all metal hotends, but also ran into problems because of production and design errors, I have not tried the better quality heat breaks/throats yet).

Please lower the retraction setting considerably to see if it has an effect. The Monoprice Maker Select uses a direct drive. Direct drive extruders do not need a large retraction length setting. If the filament is hot in the throat (as there is no PTFE lining that in fact acts as an insulator), too large of a retraction may not be reversed when the filament cooles during the retraction.



I think you might be experiencing what is described in this question: "Extruder prints fine up until further down the print". This answer describes issues of the metal heat breaks.

To comment on your statement in comments above, I am not suggesting you should use a liner in your current extruder. I'm pointing out the differences. Metal hotends are just more tricky to operate regarding retraction and heat management.
