What kind of fan mount do you use on your FT prusa to cool the PLA filament?
I have done some searching on the Thingiverse and I got some ideas from a couple of designs, but maybe I'm overthinking the design and there is already a solution on the cyberspace!!!!
I don't use anything! I don't understand WHY I would want to. I extrude at 190 C and I would want each layer to bond to the next while they are still hot. Cooling it would be counterproductive IMHO. Maybe it's different with ABS, but I have avoided that hassle so far. I get a good bond with each layer, I get very minimal stringing, and there's no evidence of over extruding or sagging of the layers.
Maybe someone can enlighten me. Perhaps it's for very intricate forms.

Sorry, that the off set from the feed of the 100 mm
Ok. So was it that much less than 100 or that much more? And then what did you get for your EStep number after applying that correction in the formula? (100/Actual mm)*90.

I marked 2 spots on the filament for the 100 mm, then position the first one at the top of the hole in the extruder (first mark was close enough to line it up). enter the commands to do the feed, and there was 12.35 mm of filemant left of the 100 mm. So if i understand this right, the Estop should be 100/12.35*90=728.74? or 100/87.35*90=103.03?

So I finally ran trough a whole 2.2lbs roll off black PLA. Im getting more comfortable with my printer. So I ordered a bunch of different colors of PLA on Amazon yesterday (should be here tomorrow). But I had the bug to keep printing. And I remembered I had a sample of green PLA from Folger tech. The heat setting said 219 on the package. I soon realized that was way to hot for my setup. The filament was getting too hot and would not extruded. Had to take apart the extruder a few times to get the filament out. To make a long story short after getting the heat down (I ran my black PLA at 180c and I got this green to look pretty good at 195C) I didn't have much left to play with. But I did print a couple test things to see how it printed. I printed off a toothed linear bearing from Thingiverse. Toothed linear bearing I printed this in the fastest setting at .3 Just because I want to see how it came out and I didn't have much filament left. When I get my other rolls I'll try it at .1mm. Has anyone printed these and tried them in there printer?

Folger's recommended temperature for PLA is way off.
I have not tried them in the printer, but I did print a few different designs of linear bearing and tried them on a spare piece of chromed rod. The problem was that they showed stiction, that is once they started to move they were OK, but there was a lot of static friction to overcome before they started moving. This seems like it would be a problem as there are lots of starts and stops ratehr than continuous movement when you are printing. I was moving them by hand, and this was not a very scientific test, but was enough to put me off taking apart the printer and fitting them. IIRC, I tried this with PLA, PLA/PHA and PETG.

You need the fan for pla on something with a bridge or an overhang. I didn't think I needed one either until I printed something with a bridge.

You almost had it right. 100/87.65 * 90 = 102.68, as woodknack said. You can either enter it with your LCD screen or hook up your computer, start Arduino, change the value in configuration.h, compile it with the left button, and then save it. As woodknack also said, do the test again to make sure. You should really mark a longer length like 150 just in case it extrudes more than 100 mm. That's what he did in the video for that reason. Mine, FYI, came out to 99.
NOTE: if you use the LCD screen, make sure you take the step to save the setting otherwise it will go back to 90 when you turn it back on.

ok, so my config.h file reads "#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,90}" so i need to change the "90" to "102.68", right?

After you get that all set then do the same to your x,y and z axis. I got mine close with a caliper then i did a calibration cube and had to adjust it more.Quote

Ok, so I ran through this several times and settle on 96.8. I decided to try a 20 mm square cube and the attached photo is the result of the print. It's close to 20 mm square, if I can smooth out the print. First photo should be top and sides, second is bottom and sides.

I'm on the fence with this one. Clearly you are one of the more knowledgeable gurus here so I respect your opinion. The Z axis is the least used axis as far as cycles go. Yes, movement must be accurate to have accurate layer thicknesses. However, the lowly threaded rod, once calibrated, should yield accurate movement. The X carriage and extruder assembly all hang on the Z threaded rods, so there's no backlash or looseness there since the nuts are always being pushed down against the threads. What are the real advantages of using the lead screws other than it looks more professional?

Man I am really wanting to print this but no matter how I try I cant figure it out. I have split it into parts with cura but I cant figure out the best way to print it.
This
