Progress / To Do
This stuff should be moved to a development board and/or github:
The mechanical structure is already built. Steps needed include Steppernug open source stepper motor driver, Arduino stepper controller, z-height control, trigger, endstops, and CNC toolpath toolchain. Further development involves test-driven design with Cool DRV, RAMPS, DRV-based Pololu. Building towards universally scalable stepper controller as we begin Power Electronics Construction Set.
In particular, a big piece of development is a robust, open source Height Controller for oxyacetylene and plasma torches.
Additional Notes
- As a large x-y-z coordinate table, the Torch Table has potential applications with other tooling besides a cutting torch. One limitation is that the drive system is not powerful enough or stiff enough to support heavy cutting-tool forces.
- A modular tool mounting (possibly dual mounting, so two tools could be available simultanously) would facilitate tool changeover.
