My BLV MGN cube build/upgrade saga (ongoing)
-
You don't need to have Facebook for it and it's not really an "official" beta. The parts have been released to only one specific supplier on Aliexpress. Anyone can order them. There's no signup to get them. You just buy them
-
@dhusolo
can you answer some questions?where do the endstops on the x carriage go now? the bottom seems to be different and no space to mount the endstop.
are the mounting holes on the x carriage compatible with the hemera?
does the original hotend cooling fan cover fit?
does the original part cooling fan duct fit? -
@Veti I'm not entirely sure. I haven't seen any of the cad drawings to see how it's assembled. I won't purchase the metal parts until a suitable triple/quad independent Z axis is developed.
However I was mistaken. You do need to be on the Facebook group to have access to the beta metal parts
-
I used blind joints with my Misumi extrusions and it was worth every penny! Misumi's cuts were spot on and when done, no angle was off my more than .3 degrees using my digital square. And SOLID as a rock to! Thanks to @Nuramori for the suggestion!
-
the metal parts have now been released.

not sure if i will get them as i like a direct extruder setup, and so far its only bowden
-
@Veti that looks pretty great!
-
@Veti Ben will be making a direct drive version. I also talked to him and I'm going to be alpha testing the independent triple Z setup when he finishes it
-
@Veti I just assembled the kit and I think it's worth it even if you don't use the extruder parts. I also skipped the extruder parts because I'm using a BMG-M with Mosquito.
And I'm currently working on a three axis setup
-
Ben just posted a video about blind joints
-
@Veti Yes, I'm very interested but I think I can't wait until it's available. I need my kitchen
-
not by ben, but for 1204 there is a metal kit
-
@Veti Very nice. Did you try it?
Wondering if there every will be a point in time where a build is finished. Don't think so
-
no i made my own 1204 mounting with metal parts.
-
Very cool! Love to see the ballscrews.
Looking forward to seeing the finished product!
-
the bed is rock solid and does not move under pressure.
-
@Veti Can you please share details of your reinforcement rods and mounts? Where can I get them?

Thanks @Veti

Simple can work as well.
The part with the V groove attaches to the bed support frame, which is not shown for clarity purposes.
I like seeing the wide variety of solutions to common issues.

Amazing mod! The independent triple z-axis system from @Nuramori seems unavailable though: the zip file on Thingiverse contains only one small file (chain_mount_-_bed.stl). What happened to the design?
