PoKeys / Tool Height with Pokeys

« on: July 17, 2015, 07:23:10 PM »

Hey all,

I have a Pokeys56U driving my router. I'm trying to get the automatic tool height script to work with it but it won't play nicely.

I've set the pin up correctly. Under the diagnostics tab the Digitize LED flashes on and off in sync with grounding the appropriate input, but it just will not work with the script.

With it open circuit, hence pulled high by the pull-up resistor I get the error: "No input setup for probing", but conversely if I short it to ground I get "Z-Plate is grounded. Check connection and try again." I can't win!

Does anyone have any ideas?

Thanks, Rob.

One more thing.... When you do the MPG calibration, do you think it works or not? All the boxes just appear to be filled with 0s after going through each of the three steps.

Hi Llaves, I have the same issue and understand where you are coming from. Unfortunately I believe I have the answer for both of us, and it's not great.

The link above is by a guy who reverse engineered the USB protocol for the HB04, it states that the variable which is used to communicate the wheel status consists of 21 descrete steps to describe the speed of the wheel from full speed reverse to full speed forward. As a result this provides very little speed resolution, which is why the caching occurs.

Now what I don't understand is why there is so little reference to this issue for such a popular pendant? Maybe it's specific to our own machine configurations?
