We currently have great CNC milling capabilities at PS1 (especially for wood and soft metals), to round out our capabilities we'd like to propose CNC cutting of large sheet metal and plate. Adding a CNC plasma cutting table would allow us to utilize our existing plasma cutter for high quality CNC cuts. Bart Dring has offered to provide a CNC torch head, which would allow mixed use as a CNC and hand-operated machine, by simply switching the torch connected to the plasma cutter. We expect the purchase of this machine to be made once more space is available, after PS1's expansion into the space next door. Currently the proposal budgets for a 4x8 table, but can be reduced to 4x4 (reduces overall cost about $1500) depending on space constriants.

He also has offered to provide a torch height controller that is optional on some variations of the machine but is included on the proposed machine below.

A [https://docs.google.com/spreadsheets/d/1GL4fawisNbxL4MniDzefcDPFN-h6mwWzHrsjW0IDVm8/edit#gid=0 spreadsheet] shows the various options for a proposed CNC machine. The currently budgeted model is a 4x8 Plasma Ready Table, a kit that contains all the software, electronics, and hardware to build a CNC plasma cutter.

PS1 will match up to 60% (up to $7000) of the required funds for the purchase of the CNC plasma cutter, from the discretionary budget.
PS1 will contribute up to $7000 of the required funds for the purchase of the CNC plasma cutter, from the discretionary budget. This amount is slightly more than %60 of the total machine budget plus 15% additional funding buffer to account for unforeseen expenses, price changes, etc.
