Hello everyone. Having a time with my tool set. When I push the "tool set" button it will drop maybe .5 inch (sometimes more, sometimes less, sometimes not at all) and immediately retract. Never getting close to the actual touch puck. I know the puck itself is a simple wire to complete a circuit. However with it not even wanting to drop at all im kinda at a loss. any help is appreciated.
The z is zeroing in mid air when trying to use the set tool. even with out the puck being touched or plugged in for that matter. I have not tried touching the puck up that high yet. I normally press the button touch the spindle just to ensure everything is working properly and it does not drive a bit through the puck. and then set my working z zero. but since its been doing this ive just been setting my z manually.
The whole circuit for the Z touch is pretty simple. There is the wire you plug into the AR, which is fastened to the puck by a screw on the puck bottom. You could check to see if that puck wire has come loose. When the tool touches the puck the normally open circuit closes. If you don't have any success at the puck, you could pull the gantry cover off and check those connections. Inside the gantry arm the wire from the puck goes into a molex connector, and that wire runs into the control box. The ground also goes into that molex as I recall and it's connected to a screw attached to the gantry frame.
It sounds to me like there is a short circuit somewhere here that is closing that circuit prematurely.

I started with the puck just to verify the connection there is good. however spindle lowers and "zeros in mid air" even without the puck. i did take the gantry cover off and everything under the cover seemed ok. im in the middle of a project so havent had the time to follow all the wiring just yet. but that is next on my list once this project is done. It seems something is completing the circuit as you stated. just not sure where it is at this moment. Ill update when I have located the issue.
If it helps, my AR5 ProV6 has the following wiring: X1, X2, X3 are limit switch inputs. X4 (oddly marked TS) is the index for the 4th axis. X5 is the wire coming in to the RichAuto board from the toolset.
