Two (2) outputs are buffered twice separately and connected to independent terminals to enable hardware slaving of two stepper motors in parallel, if needed, in gantry style CNC machines. Moreover, LED indicators are provided for these three signals for easy diagnostics. The other 2 signals can also be reclaimed for other usage making the system flexible. Charge pump circuit can be disabled and the output can be used for other purposes if charge pump is not in use. Charge pump circuit operates from as low as 200 Hz to more than 15 KHz. The CNC Parallel Boards are specifically designed for CNC control with features like charge pump CPGD for safety, emergency stop Estop, Relay on. Tiny Controls offers a range of fully-assembled and tested Parallel Port Break-out Boards for interfacing your CNC machine to a PC based controller like Mach3, Turbo CNC, EMC2, KCAM etc for CNC controlling.Īll the outputs are fully buffered and the inputs are opto-isolated, filtered for noise and buffered. thanks guys.Parallel-port breakout boards: Fully Buffered, Specifically Designed for PC control of CNC machines in fact i am heading out to the garage to do more testing and checking. as i progress further into this non movement problem i will continue to post the out come good or not. I have wired everything according to specs and had 2 other people check the wiring to make sure its right, general consenses is that the wiring is correct. at this point I am asking everyone to see what suggestions they have for the non movement of my motors. when testing the motors in the MIDI tab with G00 x1 I get no movement the motors but the program says its moving.
right now i have set up Mach3 and set my limit switches and motors. they say i should change my LPT cable to the break out board first then see what happens. since I built my machine myself and used an electronics package recommended by the people that made the plans for my machine I have touched base with them on a none movement issue for the motors.
Hood, no I didn't have Mach3 open when I did the test.
Ger21 I have XP 32 bit (desktop), in fact it only has XP, Mach3, Lazy Cam, Norton and the software for my Nvidia card and the wireless card (to keep it updated) Vcarve isn't enen install yet.
