@Veti Can you please share details of your reinforcement rods and mounts? Where can I get them?
-
4x 8mm linear rods (had them from an old printer)
8x SK8

4 SCS8LUU (screwed into 2020 profile with m3 t nut)
https://www.robotdigg.com/product/422/SCS8LUU-Linear-Block2 Nema 17 2020 mounting brackets (the store from which i ordered does not sell them anymore, similar item)
https://www.aliexpress.com/item/32892098907.html2 SFU1204
the sfu1204 mount will be replaced with when i replace the other parts with the blv metal kit

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?
-
@flux_capacitor That's because he's using a different source file due to all the changes he's done.
Z Drive System.zip
If you want to stay up to date with the project join the facebook page. Thingiverse went to crap after their last update and they don't seem to keen on fixing it. -
@dhusolo Yep, thingiverse crapped the bed.
I should look at putting things on github instead.

@whopping-pochard you said: "The IR sensor. The mini IR sensor, presumably a clone, appears to have an old version of the firmware which causes premature triggering."
How can i check the firmware version and mitigate this ? thanks. -
@whopping-pochard said in My BLV MGN cube build/upgrade saga (ongoing):
@Nuramori thanks for your beautiful design! It was a big inspiration for this.
Happy to help! Looks great!
-
@flux_capacitor if you need it let me know. I'm on here too...

@whopping-pochard
hi, can you share a link or files of the back wall and electronics mounts? thanks -
As far as I gathered, if it displayed the issue, it had the old firmware. Specifically, what it looked like was it would trigger twice -- once around 8-11 mm away, and once at the proper trigger height of ~2-3 mm. You could see it as a sort of intermittent illumination at the 8-11 mm distance. I don't think you could actually check the firmware directly without an AVR programmer, which I didn't happen to have. I solved the issue by buying a genuine part.
I will carve out some time to update my files this weekend. I'm now hosting at PrusaPrinters because Thingiverse is too unreliable. Will ping here when I get them up!
