So not too much to add to my build status...lot's of wiring!
A few notes on that progress pic...
* Again I curse the instructions for making some steps harder than they need to be and some steps just really need that one last step, to affirm you are doing something right!
* I used the provided silicone wiring harness to extended the pancake, aero fan, thermisistor, hot end and so on to the rear. I added a 2 wire length for a future part cooling fan. I really wanted to use the Igus chain flex but given I would need additional connectors (Dupont style it seems) already on the harness, why not. I figure if the ehternet guys are fairing ok with their wiring, the silicone should do good too.
* I purchased a MOSFET and installed that on the top piece of electrons box, using some 1/4" plastic stand offs I bought at Lowe's. There was conflicting information on the Fugatech video about if this would work on the shipped aluminum bed. He uses a silicone bed and what came with his kit a year ago is different than what I received in March (and to date).
* I ran out of silicone wire and purchased some more. Also, since I am plugging many wires into screw down connections, I thought back to the Duet Wifi documentation I have been reading. They advised using Bootlace Ferrule connectors on the wire, then inserted into the board connections. I read a bit about those and think it's a great idea. I sourced a crimper and 800 connectors on eBay for under $30
* One of the builders posted some before and after print pictures of without direct stepper driver cooling and with. It's an impressive image and showed great gains in details if the drivers have a steady cooling airflow on them. Following his lead, I have purchased a 120 mm case fan. I'll cut a large hole in the electronics rear door for it. That'll be a lot of airflow in there!
* A few mysteries I need to resolve are the esteps for the pancake motor/Aero/Titan combination, the PID tuning and a good part cooling fan solution.
