Power supply: Maybe one or two recycled computer supplies can be used drive it. If 24V is needed, connect output in serial. On some PSU
it is easy to adjust output voltage a bit.  --[[User:Jth|Jth]] 19:07, 25 July 2012 (CEST)

The CNC Torch Table uses the heavy duty [[Electronics Case]] with the reliable [[Arduino Uno]] microcontroller that controls open-source stepper drivers called [[Steppernug]]s
External wiring is easy with the use of [[Terminal Block]]s
Fans can be powered with the voltage regulator.

=End Effector=
This is the plasma cutter that the CNC Torch Table will be designed to work with. In the event that this cutter is no longer available here are the important specifications:
Adjustable Post Flow (power plasma only) control up to 60 seconds to improve consumable and torch life. Front air pressure adjustment makes adjusting pressure easy and painless. (PowerPlasma only)
Front air pressure gauge allows quick verification of air pressure. Over Current and Air Pressure light indicators keep you updated on your units operating condition. Suitable for use with 11,000 W "clean power" generators
60AMP 120/220Volt 50/60HZ Plasma Cutter. Cuts 3/8-Inch to 1-1/4-Inch

==CNC Torch Table Prototype II'''==
Design is finished. Stepper motor controller is under way.

*First Run of Prototype II:

The first cut was done by "jogging" a single axis. This essentially verified the ability to control the torch (end effector) with a computer interface.
*need to test jogging on both the Y and X axis, Z is low priority for now because we can manually adjust the Z height for each cut.
*need to make a strait cut without Jogging, this would demonstrait an ability to control the end effector with more automation.
*need a more simplified list of instructions for software installation.
I would like to begin a '''manufacturing procedure''' for the Torch Table. This should utilize parralel fabrication, and have a complete list of skills needed.
*To fully complete Prototype II I would like to see the following
**manufacturing instructions
**parts list
**software tutorials
**user manual
***how to cut a strait line using the arduino.
***how to cut a X inch diameter circle.
***how to cut an arc.
If we can finalize a Prototype that can do these 3 things we will have both '''another useful machine at Factor e Farm''' and '''somthing people will want to replicate and improve'''. Then we can start working on other vital machines, and after people have had time to replicate the torch table and generate feedback, we can start prototype III.
*Results: the mechanical structure is robust and lends itself to torch and CNC wood milling operations. Gantry design by [[Ben Horton]]. The innovation here is the Arduino-based stepper motor controller, [[Steppernug]] - which can be milled on a CNC circuit mill. This system is a replacement for a proprietary version equivalent to the Gecko G540 in terms of current-handling ability.
