− | We would like to see a large format CNC router capable of basic and advanced work brought into PS1.
| + | 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 |
| | | |
− | * For the purposes of this authorization, the CNC router and associated accesories should be substantially similar to the description here:
| + | 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. |
− | ** A CNC router with capacity similar to a PRSstandard, with a work area of aproximately 4' x 8' x 6".
| |
− | ** A dust collector, a computer capable of running the CNC router, and a high frequency spindle of at least 2HP

| + | * Wiring - The power requirements (see below) are simpler that the bridgeport, but there will be expenses to do a proper and robust installation. |
