Heads up Now there is slight cheaper Arduino Leonardo version instead of Arduino Uno
Stepper motors info
Power supply info
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. --Jth 19:07, 25 July 2012 (CEST)

CNC Torch Table Prototype II
Design is finished. Stepper motor controller is under way.
- Sketchup Model
- Solidworks model - In progress
- First Run of Prototype II:
- 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.
- Computer Control Overview
Cutting Torch
- Oxyacetylene, oxypropane, oxy-biogas. Oxygen: commercial bottled gas or on-site oxygen generator (purchase [1],[2]) (build [3]). Steel only. Best on thick (1 inch +) steel.
- Plasma torch. Cuts aluminum, stainless, others in addition to steel. PP60 Everlast_Plasma_Cutter (alternate Everlast_PowerPro_256). Plasma gas: air or oxygen
