Hello,
This my build thread for a 2x3 desk top which I developed over the last few years. Hope you enjoy it!

Hello,

Attachment 411246
Side frames have shear panels with anchors and carbon fiber reinforced epoxy inside the extrusion slots. They are structurally rigid single pieces.
Attachment 411248
All holes and access points required for assembly are pre-drilled.

ASSEMBLY OF MACHINE FRAME:
Attach braces to the 3030 cross beam:
Attachment 411252
Front cross beam installed:
Attachment 411254
Both cross beams installed:
Attachment 411256
Main frame assembled:
Attachment 411258
Feet for the machine are 1" HDPE pucks with pressed-in 1" bolts:
Attachment 411260
They screw directly into the bottom of the extrusions:
Attachment 411262
Feet installed:

BED AND TABLE
Bed is a 2x3 aluminum sheet and 1515 stringers. All holes for assembly are pre-machined:
Attachment 411268
Install stringers:
Attachment 411270
Various 1" HDPE parts will be attached to the bed sheet. Spread out an even coat of open gear grease to all the mating surfaces of the HDPE pieces. Make sure all mating surfaces are covered:
Attachment 411272
Attachment 411274
Install the pieces, making sure grease is squeezed out a bit:

Looking good. As with others of this design...how's the side load stiffness?
Thank you fretman_2.
It feels stout so far. I think the epoxy embedment along the full perimeter of the shear plate makes the side panels quite twist resistant. There are three 3030 cross beams connecting the side panels with large corner brackets. One of them is not visible behind the gantry. See attached pic. So far I didn't see a need for them but larger flat brackets could be added to front and back if necessary.

With the main frame assembled, 20mm linear rails are installed:
Attachment 411382
Pretty straight forward:
Attachment 411384
Attachment 411386
Gantry Beam and Y/A Carriages:
3060 gantry beam:
Attachment 411390
Install 20mm linear rails top and bottom and then the Y/A carriages to the bottom:
Attachment 411388
Turn gantry around and place it onto the linear cartridges:
Attachment 411392
Attach the carriages onto linear rail:
Attachment 411394
Machine frame with the gantry:
Attachment 411396
Install big braces to gantry beam and the Y/A carriages:
Attachment 411398
Attachment 411400
Install end caps:
Attachment 411402
Attachment 411404
Attachment 411406
To finish the assembly of the main frame, plastic trim needs to be installed as shown:
Attachment 411642
Same as with other plastic parts, use open gear grease on mating surfaces:
Attachment 411644
Attachment 411646
Basic assembly of machine frame is finished:

Btw, how do you make the posted pictures show up larger? They all end up posted as smallish thumbnails but are at the 1025 pix and 500kB limit?
I tried it both as attachment and as image but no difference. Thanks.
test...
test 2
sorry.......still trying to figure out how to upload a full size image and not a thumbnail
Nice work.
