The available evidence does not define a working torch height control (THC) configuration for the Centroid Acorn controller and MillPro software. It identifies the required engineering decisions—THC wiring, arc-voltage adjustment, voltage display, and software integration—but provides no manufacturer schematic, terminal assignments, configuration values, or verified installation.
Confirmed System Information
The described system uses a Centroid Acorn four-axis control board with the MillPro software package for a plasma-table application. The purchaser reports that MillPro was recommended for plasma use, while another prospective user reports seeing a statement that THC is supported. Neither statement is accompanied by product documentation or a demonstrated configuration, so treat both as claims requiring confirmation rather than established behavior.
Configuration Gaps That Block Integration
| Required item | Evidence status | Decision needed |
|---|---|---|
| THC electrical interface | No schematic or terminal assignments supplied | Confirm how the selected THC connects to the Acorn inputs and outputs. |
| Arc-voltage adjustment | No adjustment method identified | Determine whether the THC, control software, or another component sets the target voltage. |
| Voltage display | No verified display method identified | Confirm where the operator reads the measured or commanded voltage. |
| Software configuration | No settings or procedure supplied | Obtain the MillPro setup requirements for plasma THC operation. |
| Compatible THC hardware | Proma and Neutron are mentioned only as possible systems | Require a documented compatibility statement and wiring diagram for the selected device. |
Resolve the Interface Before Wiring
- Request the Acorn-to-THC application drawing, electrical schematic, and MillPro configuration procedure from Centroid through an official support channel.
- Ask Centroid to identify the supported THC signal architecture and the controller terminals assigned to it. Do not infer connections from the four-axis description.
- Obtain the selected THC manufacturer's interface documentation and compare its required signals with the Centroid documentation.
- Confirm which component provides target-voltage adjustment and where the operator can view the required voltage information.
- Proceed with wiring only after the two manufacturers' documents agree on signal purpose and interface requirements.
Acceptance Criteria for a Viable Plasma Setup
Consider the combination resolved only when documentation identifies the THC hardware, every required controller connection, the MillPro configuration method, the target-voltage adjustment point, and the voltage display location. A statement that THC is supported does not replace these details. If Centroid cannot provide them for the selected THC, the evidence does not establish that the proposed combination is viable.
FAQ
Does Centroid Acorn support plasma torch height control?
The evidence contains a report that THC is supported, but no manufacturer documentation, wiring, or verified installation confirms how that support is implemented. Obtain the application drawing and MillPro configuration procedure before selecting hardware.
How do I connect a THC to a Centroid Acorn controller?
No terminal assignments or electrical schematic are present in the evidence. Use matched documentation from Centroid and the THC manufacturer; do not derive the wiring from the controller's four-axis capability.
Where is plasma voltage adjusted or displayed in MillPro?
The evidence does not identify a MillPro voltage adjustment or display. Confirm whether these functions reside in MillPro, the external THC, or another component before commissioning the system.
