A project log for Voron V0.1 Stock

Building a stock v0.1 to learn and make judgements on the methodology to influence my custom printer.

This log is likely to appear nit picky. There's a reason for that. I really don't want to just write a project log for a project that's been done to death. A Voron 0.1 is the subject of many videos and project logs all over the place. Doing just another one adds nothing. So to make this project worth documenting I have to do something more. That means being nitpicky and pointing out where things can improve. Overall, none of the things in this log are things I would consider "bad," so don't take it that way. They just aren't perfect.

First up is my own mistake: I ordered a DragonFLY when the PIF system only allows me to select a Dragon by default. Thankfully, when I got to the top of the PIF queue, it begins with a conversation, and I was able to explain that and it was no problem. I probably COULD have asked for a Slice hotend with this process, but I intended to go through the most common defaults/recommendations, and that meant Dragon.

My PIF person (who I won't name yet, because I can't realistically UNname them once I do, but so far they've been nothing but awesome) not only handled the mixup easily, they also pre-preemptively asked me about the nut guide. Turns out, the printed version of the nut guide exists, and works, but it's "a nightmare" to work with. They recommended a metal one, sent me to a place to buy it.

Since I am not that price constrained, and the nut guides shouldn't impact the end result in a way I care about for a testing platform, I decided to go that route. So that's one more part I need to buy eventually, but it'll save some headache.

I ordered a Dragonfly, heat sock, and heat set inserts from Deep Fried Hero. I won't really know much until I use it, but I have no problems with the sock at a glance. The heat set inserts come in a pack of 100, and I originally thought there was no way that I got 100. It looked like maybe 50. So I decided to count... it was 105. These things are small enough to throw off my gut feelings about count. 5 is such a nice number that I am willing to bet that DFH aims for 105 in every package, so that it's still at least 100 if they/the machines mess up. Good plan, and I got more than I thought I paid for, so I'm happy.

Now, that Dragonfly. My mistake that I got the wrong hot end, but I won't hold that against Phaetus or DFH. First, I ordered the sock, because I wasn't sure if the Dragonfly came with one or not. The description on the site is non-existant. That could be improved. Overall I'm happy I did get the second sock though for two reasons: one, it's always nice to have a spare, secondly the one that came with the Dragonfly isn't my preferred color.

The Dragonfly itself came in a sealed box, so I assume that all of my constructive criticism about it is on Phaetus, not DFH. The instructions tell me how to assemble it... but it comes assembled. Bit odd.

Except it's not assembled exactly like in the instructions. There are some screws that aren't installed by default. Now, those screws are interesting. Community opinion is split on whether they SHOULD be installed or not... but the instructions say to do it, and it's not done for you (even though everything else is).

EDIT: I got this wrong. I misinterpreted the (badly translated English) instructions and thought there was supposed to be screws connecting the hot end and the heat sink. Those exist in some other hot ends, and that's what I'm referring to above when I say community opinion is split. The Dragonfly does NOT have that option, what I saw was grub screws.

The tin coating around the copper is flaking off in a few minor places. I don't think that will really impact anything, and it'll be under a sock anyway, but like I said, I'm being nitpicky.

It came with a set of wrenches, but NOT the right size to put on (or take off, since it was pre-installed) the adapter. I want to take mine off, so I will need to use pliers and put more pressure on it than is ideal. But if all goes well, I won't be using the part that will have (cosmetic) damage, so not a huge deal.

Are there really no retaining screws for the heater element/thermistor? That seems ... weird.

EDIT: There are retaining grub screws. I got them mixed up with screws that connect the hot end with the heat sink that exist on some other hot ends. My bad!

The nozzle that came with is nice, and the way it sits into the sock is perfect. I know it won't look this clean once I start printing, but it's probably the nicest looking hot end I've ever personally held. 

Also arriving: the bulk of the screws I need. I'm not going to count every one, so I'll just say for now that they are fine. Any issues that could in theory exist will be found when I'm actually building.
