Coolant ON OFF / M8 M9 using Mesa 7i76e for non-Tormach machine

Hallo Everybody,

I'm sure this is a very basic question but my very limited linuxcnc knowledge is a great disadvantage.

I have Pathpilot V2.0 controlling a Denford lathe using a Mesa 7i76e card and most functions are running except the coolant ON/OFF from the interface or using a M8 / M9 command. I would appreciate it very much if someone can help me with the hardware setup and .HAL file, currently my Emergency STOP and limit switches are wired to 7 and 6 of TB6, respectively. I find it very difficult to understanding the mapping of the physical pins from using the PnCConf Wizard to the .HAL file.

Thank you very much, Danie

I'm using Axis and this is how my coolant signals are connected. I am using a 5i25+7i76.

# ---coolant signals---
net coolant-mist <= iocontrol.0.coolant-mist
net coolant-mist => hm2_5i25.0.7i76.0.0.output-00

The iocontrol.0.coolant-mist is connected to the signal coolant-mist and then the signal coolant-mist is connected to the physical pin hm2_5i25.0.7i76.0.0.output-00. The "<=" symbols are just for the human reading the file and is not an actual operator so you can think of the signal path like this iocontrol.0.coolant-mist => coolant-mist => hm2_5i25.0.7i76.0.0.output-00

Hi,

Thank you very much for the feedback, solution and explanation. After some troubles I found placing the following code in the HAL file:

net coolant-flood <= iocontrol.0.coolant-flood
net coolant-flood => hm2_7i76e.0.7i76.0.0.output-00

enabled me to trigger output 0 on Pin 17 of TB6 using M8 and M9.
Pushing the Coolant button on the PathPilot interface still has no effect - I assume some additional mapping is still required.
