@mavin I use TinkSeal, it is the best lubricant for 3D printers I have found. Use it very lightly, except for inside the slide bearings, pack as much in them as possible. TinkSeal is not a grease, its all nano particles, so once its on, you can wipe off with a cloth and there will still be a coating on the surfaces. It is also great for plastic parts you print, very slippery. You can google it or I think tinkseal.com works.
@mavin If you are using a hardened nozzle, increase your hotend temperatures by +15C over recommended filament temperatures. Steel conducts heat poorly compared to brass.
@rbradford1111 Inductive probe is considerably more expensive than a micro switch.
@rbergins Maybe you can cut around the center screws with a sharp exacto knife?
We are still here and I answer questions from time to time. I am just busy printing in the meantime. 
I'm glad you got it figured out. Yes, the Mosquito has advantages and disadvantages. Removing the nozzle without holding the heat block is awesome until you really get a clog in there. At that point, the E3D V6 is nice to work with.
@mavin It should just snap on there if I remember correctly.
@mavin You have to push down and pull up. These fittings were originally designed to hold water or liquid pressure, much like the sharkbite fittings you find at your local hardware store.
@mavin Are you letting the hotend come up to full temperature before loading filament?
@mavin Those are great until they clog. Hardened steel can be heated with a blow torch to burn out the plastic. Just make sure you quench it in antifreeze to retain it's hardness.
@mavin Use Prusa MK3s profile. Double check the print area is 9" x 10".
I'm on Linux at the moment, but I will spin up a Vm a little later and try everything out. Thanks!
Printer x-axis is still perfectly level. I am in about 15,000 parts since the creation of the modification. I checked the clearances with my calipers and it is still right on. No longer worry about part separation or mid print failures from the gantry being out of sync. Before printing, I set Z=0, probe the bed in 106 spots, load height map and print.
@cpat You either have a E3D V6 or a Sliceengineering Mosquito. If you post a picture, I can advise you on nozzles. Either way, I would suggest purchasing hardened steel nozzles.
