What is a MechMate?
It's an open sourc CNC machine in sizes up to 6' x 20' and 10" to 13" of Z. All the plans and support can be found at http://www.mechmate.com.
--------------
When I first started the build of my MechMate, one of the hardest parts wasn't the physical construction - it was the lack of a single, comprehensive bill of materials (BOM). Over the past four months, I have scoured the MechMate forums and other sources to develop the most comprehensive and detailed MechMate BOM to date. It is my hope that this resource will help take down one of the major barriers to building a new MechMate.
A few notes on this BOM:
Link to the current MechMate BOM in Microsoft Excel (2003 format):
- This list was compiled for my personal build of a 49"x97" (working area) MechMate. If you are planning a larger, smaller or custom sized build you will need to make adjustments.
- All suppliers listed in the BOM are in the US. I hope that non-US MechMate builders will still find the BOM useful as a bolt is a bolt, even if you need to adjust it for metric and/or a different vendor.
- This BOM should not be downloaded and then followed by rampant ordering. It was intended to be partnered with a complete copy of the MechMate plans and an understanding of the MechMate design. If you can't envision the MechMate 2D drawings as a completed unit, I wouldn't start ordering.
- I tried my best to consolidate the number of vendors, even if it raised the cost by a few dollars. Three of the vendors on the list don't have on-line ordering, all the remainder do. I've ordered from every vendor in the BOM and have had good success, if you don't, please let me know and I'll try to address it.
- Included with this BOM is a "time and tools" sheet. As I completed each section of my build, I recorded the time it took me to complete each step and the major tools required. Be aware that these are my build times and the time to complete each step is highly dependent on the skill and tools of the builder.
- The basic cost of the MechMate is as follows:
- Table+motors: $4,500 USD
- Drivers+electronics (less CAD/CAM): $3,000 USD
- Dust Management: $500 USD
- The total cost of a complete MechMate without a spindle or vacuum table, is about $8,500 USD. This easily puts the MechMate on par with commercial units in the $15,000 to $20,000 USD range.
- While I have spent dozens of hours in an effort to ensure this BOM is completely accurate, mistakes and changes will happen.
- This BOM is intended to be printed on the same 11"x17" (A4) paper as the MechMate drawings.
