FlashCut CNC Architecture and Driver Compatibility
FlashCut CNC performs all motion processing in its proprietary signal generator hardware rather than on the PC, so the software cannot drive any motor driver on its own. For third-party drivers such as the Logitrol unit, the signal generator outputs step and direction signals, which are the standard interface these drivers accept. Compatibility therefore hinges on purchasing the FlashCut Software/Signal Generator combination and cabling the signal generator outputs to the driver's step/direction inputs.
Demo Version vs. Licensed System Capabilities
The downloadable demo version is functional for offline work but will not produce motion. If the demo will not let you set the controller online, that is expected behavior, not a fault. Make sure to download the demo version rather than the live version when evaluating the software.
| Capability | Demo Version | Software + Signal Generator |
|---|---|---|
| Create G-code | Yes | Yes |
| Import DXF files | Yes | Yes |
| Full simulation | Yes | Yes |
| Cut parts (machine motion) | No | Yes |
Integration Procedure for an External Driver
- Purchase the FlashCut Software/Signal Generator combination; the signal generator is mandatory for any machine motion.
- Fabricate a cable connecting the signal generator's step and direction outputs to the corresponding inputs on the driver. The evidence does not specify connector pinouts or signal levels, so confirm both against the FlashCut signal generator documentation and the driver manufacturer's input specifications before wiring.
- Create or import the part program in the software (G-code or DXF) and run the full simulation to verify toolpaths before enabling motion.
- Enable the drive and run a low-speed verification move, confirming each axis follows its commanded step/direction direction and distance.
FAQ
Does FlashCut CNC work without the signal generator?
No. All processing is done in the signal generator, so the software alone cannot cut parts. The demo version only creates G-code, imports DXF files, and runs full simulation.
What signals does the FlashCut signal generator send to a motor driver?
It outputs step and direction signals, which connect directly to the step/direction inputs of third-party drivers such as Logitrol units. You need to make a cable between the signal generator and the drivers.
Why won't the FlashCut demo let me set the controller online?
That is by design: the demo has no signal generator attached, so online control and cutting are disabled. Download the demo version (not the live version) to evaluate G-code creation, DXF import, and simulation.
