Mach3 USB for CNC: RNR Universal USB Motion Card is designed for Mach3 software. Its functions and features are as follows: - Supports up to 4-axis linkage control. The 4th axis can be set as the slave axis. - The output pulse is 100K. The minimum error interpolation algorithm is high processing accuracy. - USB interface, suitable for any netbook with USB interface, laptop, desktop and tablet PC compatible computers - No driver Designed to be better compatible with various hardware and software environments (x86 and x64 bit). We have tested it with Windows 10 systems and it seems to work fine. - Supports automatic homing (return to zero) - Slave axis auto-levels at homing - Supports automatic tool setting - Supports emergency stop input - Support limit switch access - Support spindle control (PWM mode and relay mode) - Provide 4 channels with optocoupler isolated digital signal input - Provide up to 12 digital signal inputs - Provide 4 channels with optocoupler isolated relay output - Support handwheel Interface - Interference design, imported industrial components, high reliability
