8.0 Specifications
6 axes of coordinated movement plus a spindle.
Spindle control may be Step & Direction, PWM, or discrete on/off.
Maximum Step Frequency is 4 MHz
I/O: Port 1: 12 Outputs and 5 Inputs
Port 2: 12 Outputs and 5 Inputs -or- 4 Outputs and 13 Inputs
Port 3: 6 Inputs (3 differential and 3 single-ended)
Grand Total: 24 Outputs and 16 inputs, or 16 outputs and 24 inputs, depending upon
configuration.
All outputs are 5V CMOS logic.
Port 2 pins 2-9 have CMOS thresholds (input and output).
All other inputs are TTL, except for 3 of them that are differential and are intended to be used with an
encoder. Except for Port 2 pins 2-9 and the differential inputs, all other inputs are Schmitt Triggers.
All outputs capable of sinking or sourcing 32 mA.
An expansion port is available for future expansion, which will allow for practically unlimited I/O that
does not have a high speed requirement (roughly 10 Hz, which is as fast as Mach3 processes most I/O).
The interface to the computer is through an FTDI FT245RL USB chip. The interface is Full Speed USB,
which is 12 Mbps. USB 1.1 or 2.0 required
Power Requirements depend upon load. You may optionally choose to power from either the USB 5V or
an external 5V (via screw terminals or pin 26 of either 26-pin header).
