Fixing up a used M2

Post by Karl_Williams » Thu Feb 11, 2016 1:56 am

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.

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. :D

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!
