It has taken a little time, but I've crafted an enclosure. I don't like it, the holes are in the wrong positions, there isn't enough clearance in some places, too much in others, but it is good enough for me to keep things contained.

Here is the controller in its box. Most of the time has been me and Marlin working together to solve some problems.

Challenges:

One of the two BL Touch units I have is bad. It goes into probe mode, but when making contact with the bed doesn't trigger. My other one triggers just fine. I have two extruders I'm configuring so I can live with one while the other is replaced.

Some of the driver modules I have from BTT are reporting a TMC Communications Error, I'm working with BTT to get those replaced. I have an extra module so I'm able to continue.

Progress:

All Steppers are moving! Better yet, moving in the correct directions.

I've configured the system for dual Z steppers. I don't have a dual extruder, nor do I intend to add one. I've configured the second extruder channel to be a second Z axis stepper. The board supports one Z stepper driving 2 motors, but why have that extra load on the driver. Additionally, that enabled me to auto tram the Z and X axis.

BL Touch is working. I have auto bed leveling and am using the BL Touch as the Z Axis probe.

Things I have left to do:

1. Case Fan

2. Finish the BL Touch calibration

3. Filament runout sensor configuration

4. RGB Light configuration

5. Connect in with the Octo-print system I had before

6. Calibrate all the other printer bits.

A lot to do, but progress is being made.
