I wanted to make a note that THIS MOD CURRENTLY ONLY WORKS WITH THE EASY TO LEVEL BUILD PLATE. Sorry for any inconvienence, but I will likely look into a workaround in the near future.
It was brought to my attention that 320mm rods were too long, and that 310mm fits just right. I have updated my link and BOM to Misumi 310mm rods, As I believe that is the only place you can get 310mm (or any custom size for that matter..). Sorry for the confusion!! In the meantime if you already have 320mm rods they can be cut, but just needs to be cut slow as to not warp the rods.
I finally finished the assembly manual for the Project Tripod. I tried to be as thurough as possible, but if something does not make sense or there are grammatical errors, please bring them to my attention. THANK YOU!
My confusion.. I had the wrong corner bracket in the file download (connects the bottom rod holder to the Moai). I have updated with the correct part. If you downloaded anything before 2/19.. please make note and get the correct file. Sorry for the mess-up!
Added a BOM "Bill of Materials" To the download files. Should have build instructions within the next few days.
I have added a new rod holder for the top which eliminates the need for the shim. you still need to of the "lower rod holders" for the bottom. I am leaving the shim available for those that still need it, but if you are downloading for the first time you WILL NOT need the shim for the upper rod holder.
I have had my Moai for almost a year now and have always told myself that the Moai (as good as it is) COULD be better… A LOT better! I rely on the Moai for jewelry so there really needs to be a strong degree of accuracy preferably without little lines, warps, etc etc. Now I know some people have pretty good machines that are calibrated just right and have no mechanical issues, but I believe the Moai (along with most resin printers) have one design flaw…having only one z-axis rail for support!
If you look at the Moai and just barely touch the build plate you notice it can wobble without using much force. I know many will say that it really does not matter and that it really does not move during printing OR the popular… did you tighten all the bolts!!
I personally believe that even the smallest bend in the z-axis screw, or rail can deform a print or cause wobble. Some of don’t even notice it because you are printing small non-geometric shapes. Heck, sometimes I don’t even notice it…that is… until I am doing cleanup on my casted jewelry and I notice bumps/waves in the metal.
With all that said I wanted to share a project I have been working on that I have named Project Tripod!!
Build instructions with Bill of Materials have been added to files, but a quick reference....
You need to print:
1 Build plate Bracket
4 L shape extrusion brackets (for mounting the bottom rod ends to the Moai).
2 End Caps
2 Lower Rod Ends
2 upper Rod Ends
You will also need two LM8UU bearing holders found here:
Other stuff needed to complete the build:
Two LM8UU Linear bearings (I dont recommend using cheapies).
40x20 v-slot extrusion
Cylinder Linear Shaft 8x310MM-- https://us.misumi-ec.com/vona2/detail/110302634310/?CategorySpec=00000042688%3a%3aa&curSearch=%7b%22field%22%3a%22%40search%22%2c%22seriesCode%22%3a%22110302634310%22%2c%22innerCode%22%3a%22%22%2c%22sort%22%3a1%2c%22specSortFlag%22%3a0%2c%22allSpecFlag%22%3a0%2c%22page%22%3a1%2c%22pageSize%22%3a%2260%22%2c%2200000028941%22%3a%22mig00000001498696%22%2c%2200000028938%22%3a%2200000028938.a!00001%22%2c%2200000028939%22%3a%2200000028939.b!00002%22%2c%2200000028940%22%3a%22b%22%2c%2200000028942%22%3a%22d%22%2c%2200000028943%22%3a%22310%22%2c%22fixedInfo%22%3a%22MDM00000540771110302634310-1518478229%7c13%22%7d&Tab=wysiwyg_area_0 IF YOU HAVE LONGER RODS AND HAVE TO CUT THEM, THEN DO IT SLOW AS TO NOT HEAT UP THE RODS!!
