Hi I have just bought a Texas Microcircuits serial port speed control board (apparently developed by SoundLogic) I have loaded the plugin and using the XML suggested.....nothing narda zip ... an M3 command does nothing at all... Any ideas folks??

If you are using the parallel port driver you will need to enable the spindle relay option. You dont actually need relays hooked up, just Mach requires you have that setting enabled. You can set up fictitious output numbers for the relays. You will find that setting from Config menu then Ports and Pins then Spindle Setup.

Are the LED's on the PCB operating correctly ??  (do they come on and show CW rotation etc when spindle is turned on/off within Mach - M3 / M5).

Also it is important that you are using the licensed version of Mach and not the Demo version.

Tweakie.

Hi

Thanks for the replies...but..yes the relays are enabled and No LEDs  at all

Could anybody send me a tested XML there are some odd settings in the one I downloaded from Texas microcircuits site (might be right what would I know!)

Sorry - within Mach 3 leds do come on just fine

Perhaps crossed purposes here 

Do the leds on the Texas Micro board operate correctly ??

Sorry - being stupid . No the LEDS on the board stay off. On the computer screen in diagnostics the output LED flashes.

No sign of life on the board at all

Attach your xml and maybe someone can see a prob.

I presume you have checked that you have 115V or 240V power going to Texas board and that the fuse F1 is intact (test with multimeter).

Tweakie.

yes fuse and power are ok

I will get back to you with the XML that texas MC provide
