The next step is to attach the back assembly. It comes pre-assemble with the power supplies wires.
It took about 8-10 screws to attach it.

Next you open the extronics sections and finish some fo the wiring.
I really like the new connectors and PCI connectors for the drarf boards.

You really have not smelled any thing bad until you smell one being drained in the desert heat of Iraq. Gag a dog off a gut wagon.Ya they are real sweet in the summer time.
It is interesting in the printer design that the top rails are partly cantilevered.
Yes and it is sturdy.
This is the back with 2 power supplies and the electronics. Time to wire. It came with most of this assembled.
Print Bed Porn:
The print bed is comprised of 16 individual PCB heat beds.
They are individually wired to a junction box on the bottom of the bed. They use Molex connectors, so the harnesses are easily replaced.
The best part is that the bed came assembled.

Bed, Side Pannels, and extruders were added next - pretty easy printer to install.
It took me 6 hours to build. I spent 3 hours on support chat because i corupted the firmware. It is now working perfectly.
Why would I recomment the semi-assembled kit? Eventually you are going to have to fix it and you will learn how to take it apart. That and it will save you $500 plus $100 shipping.

Quite a few actually, but I'll begin with just these two.
1) Footprint, how much more countertop space does it take up compared to the MK3S?
2) When run open, is it quieter or louder then an MK3S?

What is the max print height?
36 cm x 36 cm x 36 cm or over 14 inches.
1. about 30-32 inches x 32 inches. I have it on a 36-inch x 36-inch table with room to spare. So it requires about 10 inches more in depth and width.
2. Much quite. Even the tool change is quieter.
Any more questions?

Are any of your printers logical to bring to the launch site to either let people see and understand the process. Sure, I think most in rocketry right now are pretty familiar if they're intersted in that technology, but for people who don't, seeing one making random whatnots at an event could be interesting. I know my resin printer would be a bit awkward to set-up, level and use, but if any of your printers are easy to quickly set-up and wouldn't be negatively affected by the field environment, it might be an interesting thing to consider someday.
Regretfully, I'm missing Freedom Launch this year, but that would probably be a good way to expose some people.
Just a thought.

How will/does the XL enclosure work?
That has not been finalized yet. I suspect two optional additions will be: 1. An accordion enclosure on the outside or 2. A full enclosure that is a beheamoth.
Not at freedom launch, but I might be able to bring a Prusa Mini to a NAR launch. I need someone else to run the launch.
Did you say how many tool heads your XL has? One to start? Any MMU upgrades for the XL planned in the future, or just add more nozzles?
- Did you say how many tool heads your XL has? Two.
- Any MMU upgrades for the XL planned in the future, or just add more nozzles? No announcement on this. I suspect not in the short term. They are planning the two enclosures above and I am not sure if either, one, or both will make the market.
Review:
The build was straightforward. The most challenging part was the wire management and hiding it. A little frustration with the calibration, but that was corrupted firmware. That can happen with any printer.
Comparison to other large printers:
I own a CR10S Pro, Anycubic Chiron, and Anycubic Predator. I have seen a bunch at trade shows and have also watched a ton of videos. The XL is straightforward to use and simple to set up. It is the quietest large printer I have ever used. I would guess 1/4 to 1/2 the noise.

Pros:
- Multi-head / true multi-material - up to 5 heads
- Quiet
- Sturdy as hell
- It comes in a kit to save $500+
- The perfect flat first layer every time
- High-performance Nextruder with planetary gears
- Print bed with separately heated segments
- Reliable and easy-to-use
- Open source
- No cloud requirement
Cons:
- Pricey. The cost is $2500+. 3500+ for four heads
- Large - expect to need 3'x3'x3' (0.9 meters squared)
- Input shaper pending
- It may have an issue with textured sheets

Thanks for all the detailed info. I'm envious.
That's good info - thank you.
I appreciate the detailed information you've provided. I'm curious how you've determined the Prusa XL is reliable at this point? Reliable to me means that the device runs without failure for a long period of time. You've only had the printer running for a few days. Do you have a different definition of reliable?

Does the XL have the same firmware as the Mk4? Sans the frame, are the components the same?

For input shaping my understanding is that the accelerometer based XL firmware is on a separate development path from the MK4 which does not have an accelerometer.
I have heard rumors both ways. The Mk4 has an upgrade with an accelerometer if they ever bring it to market. I do not know much, but a source confirmed this.

Yes. Apparently there is a school of thought that open loop input shaping MK4 works well enough that the accelerometer is not needed. I would like to see one come out anyway for the MK4 upgrades since those configurations will not be as well characterized for open loop input shaping.
The alpha is pretty impressive, but I cannot figure out some things. I printed one item faster on the MK4 then the P1P by 4 minutes on a 38-minute print. Another was 22 minutes slower on a 4-hour print.
