Lots of cool stuff happening here and I felt like it would be good to try to put together a simple, concise list of ongoing work and ideas in one place. I think this will be helpful to try to paint a “big picture” of what is going on and where we are headed to help focus the efforts of the community on moving forward together. So, in the spirit of organization, here is a start that is probably a bit inaccurate. Please comment below with corrections and additions as necessary and I will update the post to reflect that. If there is a “definitive” forum topic that covers an item, please include that in your post and I will link the topic to the item in the post. If there is not a definitive topic on these, I’m happy to facilitate and link back here.
- Top Bar
- Stock – 10’ wide, 18”? above work surface.
- Improved – 12’ wide, 30” above work surface.
- Stock – 15 degrees
- Options – We know that 20 degrees is too much and 5 degrees is too little.
- Chain Slack
- Stock – bungees and slack down the side
- Improved – counterweights, slack across the top
- Stock - 10 tooth, visually set 12 o’clock
- Improved - 10 tooth, set 12 o’clock with a level
- Options (experimental) - higher tooth count sprockets
IMPORTANT TOOL - David Lang developed a spreadsheet to inform the theoretical ideal frame
- Linkage (Triangular Kinematics)
- Stock – Ring
- Options – Top Mount linkages. Although proper comparison tests have not been completed, theoretically these can provide better performance. They are also cheaper and, arguably, more simple. Doing comparison testing is hard.
- Automated Z-Axis
- Stock – Ridgid R2202 driven by a DC gear motor and encoder
- Options – There are currently a lot of designs for c-beam, linear rail systems and more universal clamps to fit a range of routers that can provide a more repeatable/durable solution but is more expensive. Free designs available on communitygarden and for sale
- Cutting System
- Stock – Router, Ridgid R2202, although the actual router used is a regional issue and we are at the mercy of manufacturers who will eventually redesign their product.
- DeWalt palm router which is cheap and available in 120v and 240v versions.
- Spindle – Quiet and offers a more detailed control over the cutter. This can be considered experimental for the maslow cnc. Cool example project (no feedback from owner on how it cuts, though).
- Universal Router Clamp – Free designs in Community Garden (Maslow tab) and items for sale (Market tab in garden)
- Arduino - Available for sale in the Community Garden
- Stock: Arduino Mega 2560 R2 or R3?
- Arduino Mega 2560 R3
- Arduino DUE – Development is ongoing. A small group of testers are using it in place of the Mega.
- Next Gen Controller – Current state is: Ideation among community members on available options. The goal is to keep with the Maslow CNC mission of making large scale CNC accessible to the most people by keeping the cost of the machine as low as possible while providing an easy path for optional upgrades.
- Stock – Unavailable (SOLD OUT)? – “original” v1.2b compatible with Arduino Mega 2560
- Options - Free designs available on communitygarden and for sale
- Shield v1.4 TLE5206, compatible with Arduino Mega 2560
- Shield for Arduino DUE (v1)
- Ground Control and Firmware
- Stock: Same routine since v? How To: Get Calibrated!
- Optical Calibration – Custom hardware/software being developed by Madgrizzle.
Holey Calibration – Started by Madgrizzle and lately carried forward by Joshua. Custom GC/FW under development. Small group of testers. Work is moving toward being merged into main branch.
Manual Calibration - c0dePr1sm has developed this technique that generated amazing results.
- Webcontrol – Developed by Madgrizzle. GroundControl on the web!!
- MaslowCreate – CAD/CAM software developed by Bar!
