Voron 2.4 350mm build upgrades

[mvdveer]

My interest was peaked by the OPENAMS development posted here a while ago. And I decided - why not. My excuse was that it would give me a good comparison between the openams and the box Turtle which I have become to love. 

Had to have a machine to put it on. Seeing I did not use the ERCF mounted on this machine, the decision was made. ERCF to the TUBS you go. 

Replacing the mainboard in the Bambulabs AMS was a breeze following the Bambu labs Wiki. A warning to those wanting to attempt this conversion - The openAMS documentation is sparse to say the least. A lot is assumed in the documentation and there are some errors in the sample configuration files. BUT - the developer of the project on discord is SUPER helpful and responsive. 

The FPS board replacement had no instructions, but was not difficult to figure out. Basically you need to reprint a new housing, use the sensor portion that accepts the Bowden tube, the new spring that is supplied and away you go.

Flashing the boards was a bit of a hassle as the latest edition of katapult caused some boards not to display their UUID after flashing. @KnightRadiant on discord was quick to the rescue with a workaround. However the FPS did not show up once connected via the can interface. Turned out the 1A mini fuse on the board was blown. Bypassed the fuse by soldering the two poles and soldered a 1A fuse into the power input. 

Both boards flashed without a problem.

Preparation of the Voron 2.4r2 350 (Stormtrooper themed Voron)

1. Removed the ERCF and Hapy Hare Software
2. Installed OpenAMS and the config files
3. Refurbished the blade in the Filametrix Filament Cutter. This machine still has a CW2 extruder but I plan to upgrade to a galileo2 in due time. (Just did not have a kit handy). Also moved the cutter to the rear right, close to the Blobifier.
4. Installed the Blobifier - another mod, I am really impressed with.
5. Removed the silicone brush and installed the bambulabs silicone pad
6. Installed the horizontal Z-Chain. Had a look at a Z-Umbilical but the chain install was easier.
7. Installed the FPS at the back of the printer
8. Placed the OAMS (Open AMS) onto of the printer: Going to run a couple of extrusions across and mount the OAMS to those.
9. Installed a Mellow Fly Canbus Extender in the electronics compartment

         

Fired up the machine and loaded the spools. 

On to the initial test. Will do that tomorrow. Decided to finish one project at a time, thus the LDO Box Turtle is gathering dust for the moment.

Also currently printing the parts for the AMS Hydra Pro - Don't know if I will proceed with this mod or not. Time will tell.

Here she is:

     

 

And for size comparison the OAMS and Boxturtle side by side:
