Fixing up a used M2

I lucked out and bought a used M2 for $200 Canadian ($140 US). The previous owner wasn't skilled mechanically or with firmware and managed to destroy the entire extruder system. I originally thought that the Rambo board was destroyed but it turned out that all of the fuses were blown. I ordered the V4 Extruder upgrade, geared stepper, extruder wiring harness, Rambo 1.3 board and Metal case, Boro glass plate and a few other things. I'm about to put her back together so I'll post with progress photos as I go. This will be my second M2. My first M2 has the dual power supply and has been printing perfectly for almost 3 year now.

I got some work done on the M2 rebuild last night
Mounted the Rambo board in the new metal case:
Printed the V4 wiring box on my working M2:
Attached the V4 mounting plate:
Attached the metal motor mount:
Mounted the geared stepper:
Attached the wiring box:
Mounted the V4 hotend:
Filament guide attached to stepper gear box:
Keeping it cool:
Extruder harness wired up with connectors inside the box:
The Next steps will be to:
1. Attach the new Z-Axis endstop
2. Wire everything to the controller
3. Update the firmware
4. Level the bed
5. Set Z height
6. Test print!

The M2 upgrades are done and the prints are looking great
I'm really loving the V4 upgrade.
Added the new Z-Axis end stop:
Wired up the new Rambo board:
Mounted the electronics in the metal enclosure and attached it to the frame. Uploaded the firmware:
Leveled the bed and set the Z height. Set up the M2 profile in Simplify3D and printed a test object:
All I need to do now is add some white lithium to the X and Y rails.
The M2 is the best!

Excellent score. And yes, the factory fan guards are garbage. Loud garbage.

That new metal electronics case is sexy I might have to get me a few of those.
Aren't you just suppose to oil the rails not grease them?

I think it's 2-in-1 for the round rods on the Z-Axis and greasing the X and Y linear rails and Z threaded rod with white lithium?

And all this time I thought the fans were the source of the noise...not the guards. Life has been changed.
Also this is a really cool post. Thanks for sharing!
