Connecting touch probe
« on: April 22, 2016, 03:17:57 PM »
Hi,
 I need some help please. How exactly to connect a touch plate for tool probing to Pokeys 57CNC ver.1.1?

i connected a cable to pin 19, opened the " input" dialogue in Mach3 and i think more or less did it. Now i touch the plate to spindle and shows blinking light at diagnostic screen istead constant light. Manual says "Probe input On PoKeys57CNC v1.0, v1.1 and v1.2 external pull-up resistor must be used"

How  do i do that and what resistor i need?

Thanks!

Hi guys .. i just ordered a Pokeys57CNC and also a bit confused about this. I understand the concept of a pull up resistor, but where do we get the VCC from for the pull up for the probe input. Any +5v on the board ?

or thinking about it now, is the resistor just inline with the probe input pin ?

The resistor should be put between the probe input and any 5V pin you have available on the board (see the pinout diagram here: https://www.poscope.com/PoKeys57CNC#tab-custom-0
