CR10S Pro Upgrades

It started with a clog, and ended up with a new sapphire MK8 0.6mm nozzle, a new copper heat block, a new BMG clone extruder (because I broke the arm on the old one when I dropped it), a new 50 tooth POM gear for the BMG, a new cartridge thermistor, a new 40W heater (because the old one was stuck in the block), and a repaired part here and there.  The POM BMG gear did require some work to fit though, aside from shims which help to center the filament grove in the gear, I had to drill out the cover of the old BMG extruder, since the shaft on the new gear was too long by a couple mm.  Instead of re-running the thermistor wires, I spliced the new one in using some of these heat shrink butt connectors, which have a bead of low temp solder which is melted by the heat gun (really cool).  I should also say that, aside from the BMG and thermistor, I had been collecting the parts for a while, and just needed an excuse to install them.

Now that it's back together, I did the following:

1. upgraded the firmware
2. reset the probe offsets and reset the z-offset (M851 X0.00 Y-56.00 Z-1.80)
3. roughly set the E-steps back to what they were (M92 E421.00)
4. ran a PID auto tune on the nozzle
5. ran another e-steps calibration and got the same value as originally (421.00)
6. Re-leveled the gantry using some blocks I previously printed
7. Performed the aux leveling (using the menu and adjusting the corner wheels)
8. Ran an ABL
9. Ran the "validate mesh" program from the "Aux Leveling" screen (was almost  perfect)
10. Saved the config using M500 on the Octoprint terminal window.

I almost went all out and installed the belted Z-axis remix I was working on (and printed) back in September, but I didn't have the time, and need this printer back up.  Once the Voron is done and working, I can do that upgrade.
