Are you using firmware with acceleration? If so it is the reason for the times being off. You could try this estimator program to get the right timesby Sublime - Skeinforge
Just realized I was wrong again because you are using 1.75mm filament not 3mm so I don't know the math to convert it from extruded to input.by Sublime - Skeinforge
OOPS just realized you are using SF41 and I am using 39 so my setting are extruded length. Divide them by 30 to get the input length. 600mm/s extrude = 20mm/s filament input? So set you max at 20mm/s (1200mm/m)by Sublime - Skeinforge
No 600mm/s 36000mm/m That is as fast as my extruder will turn without the hotend attached but with the filament in it. I use teacups old acceleration set to 50,000 and its default is 500,000. I went from having it set at 120mm/s (7200mm/m) to 200mm/s then to 400mm/s and found it improved the blobs until I reached what is my bodged extruders reliable limit of 600mm/s (36000mm/m). At 200 steps oby Sublime - Skeinforge
I just reached 120mm/s with my bowden one of the things I did to get rid of the blobs at those speeds was to set my maximum E speed in the firmware to 600mm/s. At least in teacup if you set the E_startstop_steps to 200 it will retract on its own at the above set speed of 600mm/s by 200 steps every time it goes from an extruding move to a non-extruding move and add it to the beginning of the nexby Sublime - Skeinforge
I was down for a few weeks while waiting for a new Pololu driver and when I got back to printing I downloaded this commit to find changes to acceleration in the config file without as much as a note to how they related to the old ones and after attempting to use it I found that Xon/Xoff no longer worked so I went back to using commit .

I personally use GTKterm to send the raw files to the port using Xon/Xoff with teacup firmware. This eliminated all of the communication issues I was having.by Sublime - Skeinforge
I haven't had great success using RepG or Repsnapper to send code either. So I just use GTKterm to send the file to the machine. I use Teacup with Xon/Xoff enabled. Before using it I could only get through fifty percent of my builds without have to recover in the middle. Since using it I have printed an entire prusa and a pile of other art objects without so much as a pause.by Sublime - Skeinforge

The reasons to have a removable nozzle are to make it easier to clean/re-drill as well as having different nozzles .35 .4 .5 etc aby Sublime - General

I run a bowden and had the same issue with blobs on layer change. My solution was to turn up the z speed to 5mm/s and no more blobs.by Sublime - Skeinforge
I would personally start by disabling the end stops in the firmware, this way you can confirm everything else works the way it is supposed to. If it works fine you know its an issue with the end stops and you could try inverting them. I would also use ReplicatorG for your host/slicing.

I'm not the best person to answer that question, but I have printed an entire Prusa at 20% and it is very strong. I also did a quick google, reprap wiki and reprap forum search and came up with these.by Sublime - General
Its not that you cant print things at 100% it just takes forever and takes a lot more plastic. I have intentionally printed a few pieces at 100% for strength reasons (hamming on them) and if all your other settings are correct I would assume it wouldn't cause any issues. But if you are depositing a tiny bit more material then you need it will cause an over flow effect after a little while, this dby Sublime - General
