I started and nearly completed the build minus the wiring. There are some tips and corrections I think could be useful to others. Don't use thread lock on any screws where thread lock could come into contact with the plexiglass panels - they will crack (mine cracked). I would say "hand tighten" for plexiglass should even be "stop at resistance". Since I have to remove my panels I might actually look for plastic/rubberized washer to go between the metal and plexiglass because you do move the machine around a bit while building. I wouldn't bother putting the two side panels on until after section 9 - just makes it easier to work inside the printer. In addition I wouldn't do section 7 (spool holders) until the side panels are on so after section 9 as well. Skip section 6 (bed install) until you get to wiring. You need a M3 and a M2.5 thread tap. Correction for section 2 (electronics) step 4 within says "16 x M4 8mm Button Head Screws" and "16 x M4 6mm Button Head Screws" but I am pretty sure I only needed 8 of each. If your Titan clicks or feels like it has a weird bump when manually spinning the gear you likely did what I did and one of your motor gears grub screw is on the wrong end. Grub screw hole needs to be closest to the motor away from the plastic gear. The picture shows it correctly, I just did not notice. For the Titan gear spacing I used a long M3 screw to get the "3mm" depth for the Titan gear and it was exactly right every time. I had trouble popping out the motor mount plexiglass discs so I ended up using an exacto knife to weaken two connections the circle makes to the rest of the plastic.
