The problem is that 1.5mm retraction is too little for a bowden printer. The conversation you linked is from a Wanhao Duplicator group which is a direct drive printer.
I also got a micro swiss some months ago, and after some time I found out that going back to a brass nozzle instead of the steel one included in the kit helps with stringing. I also couldn't keep the previous retraction settings of 5mm (tried a benchy and clogged the hotend after 30 mins), I'm now running 3.5mm at 30mm/s speed and I've pretty much solved the stringing problems. Also disregard the micro swiss suggestion of raising the temperatures, 200 is fine.
