Hello Maslow community
I am new to this and I recently ordered a Makermade M2 (waiting delivery). Maslow M4 seams to be a good project, but I arrived to late for the Kickstarter. Anyway, see later how it is working.
I was thinking about the frame fabrication, but I was not very satisfied with the standard or XL frame propositions.
I need a frame which can be folded vertically on the wall to save valuable space in my garage…
Also I was not certain about the wood option, for the following reasons (I may be wrong):
- Once fabricated, it will be difficult to modify if I need to make some adjustments or changings
- Difficulty to obtain assembly with good accuracy (within 5mm) due to wood deformation, etc. This will make the calibration operation even harder.
- Heavy assembly, difficult to disassemble / move if needed one day
I saw the alternatives, using Unistrut or Rexroth profiles, but it is not so easy to procure for me in France at a reasonable price.
Also I wanted to take opportunity to use my 3D printer. So I was inspired by the RS-CNC32 (MakerFr), which use aluminum profile for the frame (100 x 18 mm in France, 100 x 20 mm in the rest of Europe). And I designed a frame.
The frame use the aluminum profile beams and 3D printed parts for the assembly. It is still a draft and I will need to update when I will receive the M2 (after checking dimensions, etc.).
I took care to design with 2 configurations (10 and 12 foot top beam). And with variables to allow adaptation If needed (e.g.: profile dimension 100 x 18).
Also, I kept in mind the possibility to convert/adapt the frame for the M4 in the future. See at the end a quick draft design for the M4 frame using the same assembly system and profiles. But I will not work more on this for the moment…
I am very curious to have your opinion, on my project. And I don’t know if someone already made a similar frames ? If it was a success ?
If it works well, I will maybe share the files and drawings. I will also try to take pictures during the assembly of the frame. Maybe I could make some tutorials later if I have time. I am quite sure this frame could be convenient for beginners with a 3D printer.
The bolts are not showed, but you should understand the principle.
First set of bolts are external from the aluminum profile (sandwich) to make the first assembly and setting. This assembly can be adjusted.
When the setting and accuracy of the frame is good enough, the profile will be drilled trough the 3D printed part, then a second set of bolt can be added to block the frame geometry (it give possibility to disassemble / reassemble keeping the settings).
Edit: I cannot post more than one picture (new user), so I did a big one for the moment…
