Some Troubles With Tool Touch Off Device
Posted: Wed Jun 23, 2021 8:00 pm
I purchased a generic tool touch off device.
Wiring is as per this diagram I found on this forum: The KP-3 uses pin 2 for Vcc, pin 5 for output, 3 for ground and pin 6 for probe detect signal.
My "generic" TT-1 uses pin 2 for Vcc, pin 5 for output, pin 3 for ground and pin 4 for probe detect.
So the only difference is that I am using pin 4 for probe detect (per TT-1 manual) whereas the KP-3 uses pin 6 for the probe detect signal. The signal output pin is the same. Pin 4 is wired in the header right to ground so that when my tool setter is plugged in it is detected.
The parameters I used are from the TT-1 sheet I found on here: The issue is when I go to the Offset Lib and go to auto set Z-Ref (F1). It works and Z goes to the tool setter just fine only if my KP-3 is plugged into the other socket, otherwise I get a "probe not found" error.
When I do an Auto Measure (F3), It does not work if the KP-3 is plugged in and it says that TT-1 is not connected. If I unplug the KP-3, the Auto Measure works just fine with my tool setter.
So it appears that the auto Z-ref (F1) is looking for a probe to be attached, and the Auto Measure (F3) is looking for the TT-1 to be attached without the probe.
I assume that the TT-1 should work all by itself with both Auto Measure and Z-ref auto, but it only works fine by itself in Auto Measure.
I am thinking that one of the parameters is wrong, but the documentation on some of these is clear as mud to me.
Thank you,
Scott
