I just built my LR3 last spring, and my 3d printer at the time was dying, buuuut now that Ive got a new printer, I’m upgrading the 3 to a 4 . I’ve been printing the parts remotely while I was out of town (had a buddy removing stuff from the print bed for me). and came home to this pile of prints. upgrade parts are supposed to arrive today, just need to get the conduit to verify the size before printing braces. (and will cut struts with lr3 before tearing it apart).
Used a ‘carbon fiber’ look on the faces of the outer YZ plates, jsut to give it that look.
everything is printed in PLA+
Since it’s an upgrade, I’m using my existing lr3 table, but I’m thinking of making it so it can flip up almost vertically for storage. It’s a 4x8 bed (so table is obv. larger than that), so cant quite flip it up fully vertically in a 9’ ceiling room
Cool!
One mistake I made was cutting the struts on my LR3, before realizing later that my tube+strut lengths were different to match my LR4 to my LR3 table. Not a problem to cut new ones later, but just a tip to make sure you know what your strut lengths need to be, as the LR4 is more efficient in use of space on the X axis. Or just use printed struts for the LR4 at first, in case you need to make adjustments to the tube lengths like I did.
yeah, ive been looking at a lot of calculations to make sure the Y axis rail and left side bearing wheel will land on the same area without having to redo that part of the table =\ I thiink ive got the correct lengths calc’d but will def. re-measure everything before cutting the new rails and struts.
Finished the upgrade during my lunch break today.
Upgrade went smooth & the build was pretty straight forward.
I used the table (full sheet cutting area + some for approaching from the side) I had built for the LR3, just had to move the rail to the right of where the previous one was set. and will need to move my spoil board a little as well.
