OK, I was summoned this time, nobody gets to complain… 
What Ryan was unaware of when he switched forum software, years ago, was that the new software came with an undocumented “feature”:

Got a pile of parts in the mail today! Manta M8P with 2209 drivers, CB1 and heat sink, BL Touch, BTT EBB36 Can Bus tool head and my aluminum for my bed.

Also wanted to show the starting point for my Hemera to H2 adapter.
It will require some heat set inserts but I could make it with nut recesses to aleviate that.

Next gen version of the Hemera to H2 adapter in the making. It will also serve as rhe mounting for my EBB36 CAN board.

Waiting for new parts to print and couldnt resist playing with the electronics.
I am planning on running Klipper on this. I figured that a good start for the configs would be the Voron Trident as it uses the same three point leveling.
The Manta M8P is supposed to support CAN bus operations onboard. The documentation is severely lacking but it looks like I can set the board up as a USB to CAN bridge and it will work. It changes communication within Klipper to CAN vs serial and enables the onboard CAN headers. I will be using the EBB36 as the toolhead board which seems to be well documented.
Wish me luck!

I have pretty much the same setup, Manta M8P V1.0 (No CAN) U2C and EBB42 and the H2.
I redesign the extruder carrier to accommodate the H2, and design a fan mount (2 -5015 fans) that also holds the EBB42.

That is cool! I know I can use the U2C just wanted to see if I could get the new onboard one to work.
I looks like we went close to the same way for the mount design!
Would you be interested in sharing your config files for Klipper?

Cheers for all the info sharing! Hoping to use yours/someone’s adaptors and/or carriage mods if that’s ok.
Sounds like @probrwr has BiQU H2S Revo and @gpagnozzi is using BIQU H2 V2.0?

That is right, H2 V2.0, and the M8P V1.0 at the same time, months ago…
And yes, I will share my files once the printer is working.

I do have the REVO. As soon as i have all the bugs ironed out of the mount I will share it with you.
I used the fan shroud from another user on here. It came from @InoxDragoon from the repeat H2 Build thread. I tried the BLTouch mount but it would have interfered with the Homing so I designed one that sandwiches between the fan and heat sink. The fan mount one will work great on my Ender3 with H@ if I decide to add a BL Touch.

Working on an alternate option for bed mounting on my machine.
I made brackets for the ends that overhang the z trucks and are pinned down by springs like the standard bed to allow movement. The holes are close fit and then filleted over from the top so they give some flex space.
I plan to mount the bed on silicone deb spacers using tnuts into the extrusion.

NICE! That was actually my original plan!
Hey where did you get your 12 x 12 by quarter inch thick aluminum plate? And how much did you have to pay for it?
Appreciate this question, curious too.
Bought Alu for my LR3 XZ plates from https://www.amazon.com/gp/product/B095HBG4YF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, my other option was local metalsupermarkets.com

This is the bed. I expect it is not as good as a full MIC-6 plate but i am pretty impressed with the finish on this piece.
One did get lost in shipping on the way. USPS for the win.
