I got my first prints done today. Photos later, when I've done some tuning. I am using RAMPS+Mega for now, as the Azteeg board is out of stock, and because I'm not 100% sure what controller I want to use. It seems like there is a lot going on in 32-bit controller right now. Similarly, I am just using blue tape on the heat bed for now, as I haven't decided what print surface I want to use long term. I made a few changes from the official parts. For the E3D, I use this thermistor: www.ebay.com/itm/321490496841. It screws in, which make it much easier to attach. Two of the part from RobotDigg on the official BOM didn't work out for me. The T nuts you get with part number PreNut20 are the drop in type, and these come out very easily when you are trying to tighten things up. So I substituted these slide in ones: www.ebay.com/itm/182045608709. The thermistors with part number MF58-100K1 are an inline type, and so they don't fit very well in the hole in the heated bed. I used www.amazon.com/Anycubic-Thermistor-Teflon-Wiring-Printer/dp/B01B41K7OM instead. Also, I used some M5x10 (D11) where the instructions call for M5x8 (D10), as the count in the BOM (12) is not consistent with the number in the instructions (20 in total).

A couple of extra observations and comments.
The heated bed adjustment screws are a bit hard to use, as sometimes the whole screw turns instead of the thumbscrew. I added a lock washer on the top end of the screw (above the bed) and this helps a little but not enough. The same was true on my Prusa, but there is was less of a problem as the screw head is more accessible so I could hold it in place. Any suggestions? Maybe a nylock not under the bed?
I'd also like to see if there is a way of moving the cooling fan from the front of the extruder to the back or one side. I find it convenient to be able to see what is going on to catch any extrusion problems as soon as possible, and also to occasionally remove ooze before printing starts. It's hard to do this with the present arrangement.

It's hard to do this with the present arrangement. Solution for bed adjustment is to add a m3 nut to the bottom of the bolt right against the bed, this will hold the bolt in place and keep it from turning. However, this will mean you can't move your bed down as far as before so you will need to get a new endstop bracket or use something like a quarter taped to the z gantry in order to trigger the endstop sooner, hopefully that makes sense! Anyway, for the fan positioning, I know it is in the worst possible place but unfortunately that is the only place it would fit without losing travel! Perhaps someone else can come up with a more elegant solution and somehow duct it around from the side (back would probably be near impossible) but anyway it wouldn't be easy!
