Just to make sure it is CLEAR teh first stage of G28.1 routine is made at Rapid feedrate then from teh waypoint to teh switch location it travels at teh predefined value you set up in teh Homeing Config page. THAT rate is a % of rapid rate. 

It has NOTHING to do with the Fword call.

Teh G28.1 Z value is a way point to get back to home via that point . In this case IF teh tip was touching teh surface it would rapid UP to teh Z waypoint then probe back down to the surface . IF it is already above the waypoint it rapids DOWN to teh way point then further on to teh surface.

YOu may also want to consider increasing teh G28.1 intermediate point distance  5mm(.200") is pretty close . Here I use a minimum of .500"  . IF you have a wavy piece of metal 5mm may cause  switch contact problems

Also remember IF you have to hit the Estop that means it requires a complete reset of teh program values to be safe . ESTOP does not mean STOP it means DUMP everything. 

Just a thought, (;-) TP

The only thing I would change its to add the dwells for the switch motion to the macro  1 for extend and 1 for retract  use Sleep(200) after the call to activate/deactivate the switch.

Then remove the G04 from the Sub.

You also need to make SURE that you CAM is going to reset teh Feedrate to programed FeedRate after each  Sub Call  otherwise the next section of Gcode will run at F1300 Feedrate. Actually I am not sure WHY you are calling teh F1300 in the sub What are you trying to set  the feedrate for ALL the moves I see COULD simply be done at RapidRate (G00) and avoid teh posibility of a problem.

mach3 can Speak,  Play a wave file(sound) or signal a Beep.

It is covered in the manuals "somewhere" (;-)

This is what you are looking for.  I would steer away from the CandCNC products as they are far to complicated for the average DIY plasma cutter

You cannot just use any relay it must be compatible with the output signal of your board. Can you give us teh make and model number of your breakout board ?

NOW IF you cannot get it to work with your system like you want you MAY consider doing away with teh brain and just use a set of macros to turn the output on /off.  That way teh Solenoid will never fire on load IF you have that box checked in config.

OR you can do it all in the macropump where you have access to Isloading() to have it NOT activate while Isloading().

OK I downloaded the program file and the sub file and the brain AND it all works fine here. Everything fires when it should and doesn't when it should not.

I will say that teh CandCNC program file is severely overloaded with gizmos that don't add to your cutting experience one bit . MOST of that is not needed to run an AIR Plasma CNC cutter.  Can you explain what all teh M00 and M01 are all about ?? You may consider doing away with a lot of teh Mcode traffic in the cut file.

NOT that I am picking on you it is that I have never seen that much traffic on the Mcodes in plasma cutting before.  And Yes I do use CandCNC products from time to time BUT  I eliminate 95% of those special gizmos that have little to no REAL value.
