| + | == History == |
| + | * 2014-02-25 - discussion open on member list |
| + | * 2014-03-20 - open meeting held at PS1 to discuss the purchase |
| + | * 2014-04-01 - Announced |
| + | * 2014-04-08 - Vote passes |
| + | |
| + | == Background == |
| + | |
| + | The proposal is to buy a large format CNC router. The current CNC has work area and cutting power limitations that limit it to very small parts and slow speeds. |
| + | |
| + | At an open meeting we discussed (3) possible options. |
| + | * Build our own |
| + | * Buy a used industrial machine |
| + | * Buy a Shopbot |
| + | |
| + | The consensus was buying a Shopbot was the most likely option to achieve our goal with minimal risk. A Shopbot is a turnkey solution with a 2 year warranty and has a smaller footprint than industrial machines with similar work areas. The included Shopbot CAM software is basically the same as the smaller machine so certifications will be easier. |
| + | |
| + | Extra stuff: |
| + | * Shipping |
| + | * CNC Router |
| + | * Dust collection - If a larger, shop wide dust collection system is desired the money would be transferred to that |
| + | * Wiring - The power requirements (see below) are simpler that the bridgeport, but there will be expenses to do a proper and robust installation. |
| + | |
| + | Receipts will be linked below. |
