Netbob with Beamicon2 (interface board for CNC control of up to 6 axes via Ethernet)

Brief product description
The interface board enables the operation of up to six stepper motor or servo output stages with the Beamicon2 CNC software. A normal network connection with RJ45 cable is used for data transfer from the PC. No LPT port is required and the well-known limitations of stepping frequency and timing problems are a thing of the past. The board can be set to many different configurations. Depending on the selected configuration, additional functions such as control of a frequency inverter or speed controller, reference switch, up to 9 outputs (24V) and up to 16 inputs (24V) are available.
All signals are galvanically isolated from the PC to ensure maximum interference immunity. All machine-side signals are designed for 24V levels, ensuring robustness and compatibility with industrial sensors. Ready-made connection cables for BEAST stepper motor output stages, UHU DC servo controllers and brushless servo systems (SpeedCube and Sanyo-Denki R series) are available (not included in the scope of delivery), so that fast and error-free wiring is possible.

Functional description
In contrast to conventional breakout boards with LPT interface, which only forward the signals from the PC and adjust or amplify the signal level if necessary, the Beamicon2 interface board has a powerful 32-bit processor that can generate step and direction signals in real time independently of the PC. The PC only sends coordinates at regular intervals via a network interface (Ethernet IEEE802, 10MBit/s). All hardware-related operations run on the interface board, so that the PC is relieved of time-critical tasks and is only needed for the user interface.
Significantly higher step frequencies are possible than with LPT port-based solutions, and the timing is more precise and reliable. Compromises in the choice of resolution in connection with the maximum possible speed are therefore no longer necessary. Servo drives can also be operated with high resolution and speed. Step losses due to brief "dropouts" of the PC (violations of real-time conditions due to competing processes) are eliminated.
Setting the pulse duration and spacing, which is often difficult for the user to understand, can also be completely eliminated. The breakout board always generates the step signals with a duty cycle of 50%. Direction changes always take place in the middle of the pauses between clock pulses. This ensures that the maximum pulse duration matching the frequency is always output. Violations of the setup and hold time due to simultaneous changes of the step and direction signal status are avoided. Compared to the NetBob1, 6 instead of just 4 axes and considerably more inputs and outputs are available. The step/direction signals are differential (RS422), which simplifies the connection of servo controllers that require differential signals. All enable and status signals are available separately for each axis, so that even mixed axis drives (stepper motors and servos) are no problem and diagnostics are easier in the event of an error.
