his is a new Combo break-out board developed by Jim Cullins to be used with the Mach2 or Mach3 PC controller. Jim Cullins removed the step and direction LED lights and put them on a small PC board. On the back of the board is a binary (2,4,8,16 count down) that lets you better view the step pulses. If you like you can mount the LED board to the front of your control box. The LED board is also available for use with the standard breakout board. The price of the LED board with the Standard breakout board is $24.95. The LED board is provided free with every Combo board. The Rev 5 board uses a PIC processor to process the spindle speed pulses. The Combo board was requested by a large customer. The main advantage of the Combo board is space. The Combo board fits in the same space as a breakout board (6” by 5 5/8”). The cost is $20 less than the combined three boards. Even less now if you want the LED board. For some customers doing retrofits, space is a necessity. All combo boards ship with a LED board if requested. The purpose of the Combo board is to interface the PC parallel port to the Gecko stepper motor drives and to control four relays for powering on aux devices such as spindle, vacuum pump, and coolant pump from 115VAC. The combo board also includes the spindle speed function that can control a variable frequency drive (VFD) through an optically isolated 0~5 VDC or 0~10 VDC. The Combo board also has an output for one Quadrature encoder that can be used for a manual pulse generator (MPG). Mach 3 can output a 15khz pulse string to pin 17 on the parallel port. The new break-out board detects this pulse string and enables pins 1, 14 and 16 for outputs. the outputs can be uses to turn on things like spindles, vacuum pumps or coolants (through a solid state relay). If the 15khz signal is not present, the outputs will not be enabled. This will prevent outputs from coming on when Mach2/Mach3 does not have control.
