thanks, i got it working. i figured it would not be a good idea to fire it up without an estop.
i also tied in the stepper drive fault back into the board. Took a bit of trial and error but i got it with this. I tried originally to use axis instead of joint as i found reference to doing it that way but i could never get it to work. am i doing this correctly or am i off base?
Code:
# ---Axis fault --- net axis.x.fault <= hm2_7i76e.0.7i76.0.0.input-13 net axis.y.fault <= hm2_7i76e.0.7i76.0.0.input-14 net axis.z.fault <= hm2_7i76e.0.7i76.0.0.input-15 net axis.x.fault => joint.0.amp-fault-in net axis.y.fault => joint.1.amp-fault-in net axis.z.fault => joint.2.amp-fault-in

MIne's a bit more complex
Code:
# --- ESTOP CHAIN STARTS --- net latch-reset <= iocontrol.0.user-request-enable net latch-ok-in <= iocontrol.0.user-enable-out net latch-ok-in => estop-latch.0.ok-in net latch0-out <= estop-latch.0.ok-out net latch0-out => estop-latch.1.ok-in net latch1-out <= estop-latch.1.ok-out net latch1-out => estop-latch.2.ok-in net latch2-out <= estop-latch.2.ok-out net latch2-out => estop-latch.3.ok-in #net latch3-out <= estop-latch.3.ok-out #net latch3-out => estop-latch.2.ok-in net latch-reset => estop-latch.0.reset net latch-reset => estop-latch.1.reset net latch-reset => estop-latch.2.reset net latch-reset => estop-latch.3.reset net latch-out iocontrol.0.emc-enable-in <= estop-latch.3.ok-out net estop-out estop-latch.3.fault-out # --- EXTERNAL ESTOP SWITCH - CONTROL BOX--- net external-estop <= hm2_7i76e.0.7i76.0.0.input-00 net external-estop => estop-latch.0.fault-in # --- EXTERNAL ESTOP SWITCH - CONSOLE --- net console-estop <= hm2_7i76e.0.7i76.0.0.input-31-not net console-estop => estop-latch.3.fault-in # --- PENDANT ESTOP SWITCH --- net pendant-estop <= hm2_7i76e.0.7i76.0.0.input-26-not net pendant-estop => estop-latch.1.fault-in # --- TORCH BREAKAWAY E-STOP --- net torch-breakaway <= hm2_7i76e.0.7i76.0.0.input-06 net torch-breakaway => estop-latch.2.fault-in # --- E-STOP STEPPER DRIVE DISABLE --- net estop-out hm2_7i76e.0.7i76.0.0.output-05

I think I'd like to take the breakaway out of this chain and just make it pause the machine.

If you have connected it correctly the Plasmac branch will handle torch break away well with the plasmac component. I have lots of experience with it now! I actually haven't lost a part since starting to use Plasmac. You do actually want it to pause and not put the machine into estop if you don't use Plasmac.

Rod,
I have written a configurator to create a plasmac config. I have posted it in the Another plasma component and you may want to link to it in the first post.

Cheers, Phill.

first of all thanks to those who are doing this good job.
I'm doing the first tests with a 7i80 + 7i30 + thcad 0-10, the motors work and the voltage is read .. I would like to know how to use this thcad mode 0 or 1? I also have the arc-ok signal that I used with an analog thc.
Thanks in advance

The THCAD mode select (W1) should be down to select unipolar mode. This gives you a 0-10v range not -5v to +5v
You should also select the divider link to 1/32 and adjust your full scale frequency and offset accordingly (eg divide the calibration spec by 32)
