So I realize I haven't officially updated this in a while, but I wanted to give you a sneak peek behind the scenes at what I've been working on.

The enclosure will feature a GX16 connector for the heated bed, D-Sub DB9 connectors for stepper motors and limit switches, and a D-Sub DB25 for the hotend (running the heater cartridge in parallel, even though the pins are rated for it).

This enclosure will host the Melzi board and a Raspberry Pi 3B+. The lid will hold the TL Smoothers and a fan for active cooling (fan size TBD, probably 60mm). In theory, I should also be able to fit a LM2596 and a small BUSBAR in here without issue as well, achieving the initial goal with a simplified solution.

You should do a mock-up in Fusion 360 so that it makes more sense and also you'll get an idea of spacing. Some people need visuals.

I've actually been tweaking this finding exactly how I want to lay it out based on how I'm vamping my Enders (which has changed dramatically).

I'm going to stay true to my standard design, but also want to incorperate 2 printers per PSU (Meanwell RS750) for example while minimizing wall space required.

I haven't forgotten this project I just didn't want to keep spamming it with updates until I settled on what layout I was going to go with.

I don't know if I would want all my printers on a shared PSU unless it had backup power. I was going to do the same thing with my Raspberry Pis but I need to get some switches just in case I need to power cycle.

I don't know if I would want to print without a battery backup :)

Comments deleted.

Could you explain how these boards are supposed to be installed on the printer?
Are you supposed to stack the on top of each together (e.g. the circuit board sits on the TL smoother board)?
Do you mount each/both into the Ender 3 circuit board chamber, or where?

These mounting boards are actually designed so you can remove the circuit board/TL Smoothers/etc from the printer and mount them on another surface. In my case, they will be mounted on the wall directly behind the printers. This is what I was referring to when I was talking about extending the cables.

I've included a poorly-drawn paint diagram to depict the layout until I can get everything printed, circuitry mounted, and some pictures taken.

Heya! Thanks for stopping by. I'll try to be active both in the comments and the info page with updates, discussion, etc. Let me know what you want to see.
