I just recently got my Maslow CNC kit in and I am extremely excited with the potential that this kit has to offer, the amount of customization that you can apply to it, and the community backing it.
I have been doing a lot of reading on this site prior to building my frame so I can try to capture as many lessons learned as possible, but I want to make sure I do not miss anything major/important.
This is my current plan for the frame:
- 12’ 8020 Beam for the header (reduces deflection, able to adder roller to guide cables)
- Unitstrut rails to make up the rest of the frame (1/2 Height slotted hole)
- Ability to adjust distance between motors (Accuracy tuning)
- Ability to adjust distance between work plane and motors (acommodate different material thicknesses to keep the chain planar)
- 3D Printed chain guides to keep chains engaged on gears, and to lock in place when not in use
For the sled:
- Replace bricks with cylindrical containers that hold lead shot (or diving weights)
- Round edges to reduce chattering of the sled
- Connect shop-vac hose to reduce sawdust
- Using Siemens NX 11 to create G-Code
- Need to ensure linear coding is used not parametric
There are still a few things I could use help with, but I might tackle these after the frame is built:
- Cable Tension (How to improve tension in the corners to increase accuracy)
- Improved Z-Axis control methods for the sled
- Configuration of spoil board / excess
Let me know if you think I have the full scope covered, or if there are some other things that I should be considering. Also if you have a particular forum post you think helped you greatest, feel free to share.
