If you have Probe configured active low and configured to pin 10 and enabled then connecting pin 10 to GND (pins 18 - 20 of the parallel port) will light the Digitize LED.

Perhaps you are not connecting pin 10 to GND (the machine spindle or machine frame may not be GND).
Perhaps what is labeled pin 10 on your BoB is not actually pin 10 (check continuity of wiring).
Perhaps pin 10 on your parallel port has died (try another input pin#).

OK.
Now if you connect pin 10 (probe) to GND the Digitize LED on the Diagnostics page will light. Why would you need any other verification of the operation ?

Are you configuring the input pin# you are using to the Probe input in ports and pins and enabling this input ?

What type of controller board is it ?

No prizes, but who can suggest the best caption for this photo which I took this morning ?  ( bugger has already been used ).

I'm sorry, circle pocket works fine, but the Roadrunner is very slow and also a lot of noise. Another thing is that when I run the Roadrunner the router almost doesn't move but the motion on the screen move fast.

Marcin,

Just a thought but the Roadrunner code is in imperial units. If you machine is set-up in metric units the roadrunner image would be only 7mm x 6mm. (you could try putting a G20 at the beginning of the code)

Craig,

Any input pin# is OK.
Whichever you choose has to be configured to Probe in Ports and Pins.

Hi Beefy,

As luck would have it, despite many computers, I have never had this problem except with an old Dell Inspiron laptop and even then the XP optimization cured the problem.

It seems that your PC is running something else in the background perhaps the Windows Task Manager may shed some light ?

The resistor is used to pull-up the voltage on the the plate to +5 so the resistor goes between the plate (pin10 ?) and +5 volts. You could get the +5 from a spare USB socket if you have a USB lead you can cannibalise.
When the tool touches the plate it should then make the plate (pin 10?) zero volts.

Beefy,

If your PC has onboard video graphics there is a high probability that it will not work. Fitting a plug-in PCI video card then enabling this and disabling the onboard in BIOS often does the trick - but not always.

Hope this helps.
