Second Probe

How would one add a second, inverted probed onto a 7i96 card? I currently have a touch probe that closes a ground loop between my router bit and a metal plate. I built a touch probe for G-Ripper that opens a ground loop, therefore they can't be paralleled. Does one need to use motion.probe? Can one add another pin that will act like the same?

Hi

I guess if I look at the forum list, I might have seen this
I followed the text file you posted, but the error I get upon opening axis is that and2 already exists at loadrt and2 names=and2.combined.setter.
Here is what I changes the text to, in my custom.hal file if that might matter:

# --- probe signals separated for probe + toolsetter with status checking and possible bypass from macro ---
loadrt or2 names=or2.combined-touch
loadrt and2 names=and2.combined-probe
loadrt and2 names=and2.combined-setter
loadrt not names=not.combined-probe-on
loadrt not names=not.combined-setter-on
addf or2.combined-touch servo-thread
addf not.combined-probe-on servo-thread
addf not.combined-setter-on servo-thread
addf and2.combined-probe servo-thread
addf and2.combined-setter servo-thread

I appologize with this setup you need to use

[HAL]
TWOPASS=ON


or you need to do the loadrt in only one line like thi exemple
loadrt and2 names=and2.combined-probe, and2.combined-setter
loadrt not names=not.combined-probe-on, not.combined-setter-on

That worked, but I had to do this in the hal fil, change from
#loadrt [HOSTMOT2](DRIVER) board_ip=[HOSTMOT2](IPADDRESS) config="num_encoders=[HOSTMOT2](ENCODERS) num_stepgens=[HOSTMOT2](STEPGENS) num_pwmgens=[HOSTMOT2](PWMGENS) sserial_port_0=[HOSTMOT2](SSERIAL_PORT)"
to this
loadrt hm2_eth board_ip="192.168.1.121" config="num_encoders=1 num_stepgens=4 num_pwmgens=1 sserial_port_0=1"
The debug from starting the file was telling me I had a rtapi-app-main:permission denied in the start-up

BUT,
now when I start the cnc program, I can't home the Z axis easily, as it stops on probe input, and then the Y axis claims it is not in sync (dual motors). I took out the twopass, and tried
loadrt and2 names=and2.combined-probe, and2.combined-setter
loadrt not names=not.combined-probe-on, not.combined-setter-on
starting the cnc debuged out "Invalid parameter 'and2.combined-setter'
