Feedback on our XL build - Adding pictures to the hardware documentation would be of great value (and other stuff)

We are almost done assembling our FarmBot Genisis XL and it is going great!
The build has gone well, and the hardware documentation has been very good, for the most part.
The only parts that have caused us concern or confusion have been around cable management and wiring layout. What would help, I think, would be photos of what the result should look like at a few key steps.

Here are those steps:
1). When placing the cables into the cable carriers. During and after. Especially where the instructions note to avoid “criss-crossing”, as this is very hard to do on the Z & Y cable carriers. One thought would be to recommend doing it on a hot day so that the wires & hoses are more pliable. (Or cautious use of a hair dryer or heat gun)
2). After plugging in all the wires to the electronics box, we are left with quite a bit of extra cables (slack). It would be helpful to have the “FarmBot-Approved” way of managing the slack. I want to ensure that whatever method I use does not impact the functionality of the robot.
3). All the CAD drawings note “Not Pictured: The cables and tubes…”. It would be highly beneficial (imho) to have at least a CAD, at best a picture, of the end result for each of the cable carrier ends, with wires & hoses.

One other part that was tricky was plugging in the two electronic connectors to the UTM. There is not enough space to get it there and the insulation to the main cable is pretty close to the plugs. Thoughts would be:
1). Provide some type of tab on each plug that one could use to better guide and insert each plug.
2). Fuse the two plugs together so that they can be inserted as a single unit. I was about to super-glue them together, then insert them as one piece, but I managed to get them in separately.
3). When constructing the cable, separate (unwind) enough of the individual wires so that the two plugs can be moved around with greater ease. Because the wires are wrapped close together between the end of the insulation & the plugs, it made moving the plugs to orient them on their respective locations on the UTM a bit of a challenge.

And one more thing…
About the electronics box:
1). It would be a nice-to-have a tab on the door & box for adding some type of locking mechanism. (Small padlock, zip-tie, etc. Nothing elaborate, just enough to keep little, inquisitive hands out and help keep the honest folks honest. I have some long zip ties that wrap around the entire box, but we need to “burn” one every time we want to get into the box.
2). The box looks awesome, but when I close & clamp it, it does not seem like very much pressure is applied to the lid. Maybe on the next build shorten the clips just a smidge to make the seal a bit tighter…?

And yet even another thing…
It would be another nice-to-have a section in the hardware docs titled “FarmBot Build Pictures”, and populate that section with many photos from many angles of the FarmBot. Close up & high resolution. At least for me, this would help me understand & verify each step.

I hope all this feedback helps!

And even more “one more thing”…
It seems that the water solenoid is the only electronic device that does not have a cover to protect it from the elements.
I will pose this concern/challenge to the 7th & 8th grade students and see if they can design, model and print a box for it, as they have access to a 3D printer (but I fear I will have to find another one, because the one they have is pretty rudimentary.)
Having said that, it would be nice if future builds of FB came with a nice shiny grey box!

The part already exists! I had @Marc (https://forum.farmbot.org/u/Marc) help me and he brought along some spare parts. I got lucky and he gave me one that fit perfectly over top, tee nuts used to anchor it and I only had to drill one hole in the piece. … gotta love google photo… I found my picture!

Thank you for this detailed feedback!

I agree that we can improve the documentation when it comes to cabling/tubing, and completed build photos that show an ideal setup.

We’ll also look into making future electronics boxes lockable, a housing for the solenoid valve, and further improvements to the UTM to make it easier to connect the cable.

Cheers!
