You want to start at M100 and go UP in numbers. The reason being that teh numbers M00 - M99 are considered internal Mcodes to Mach3 and CAN cause problems to use externally. 

292
The problem with that is there are some things that were fixed in V.066 but it also broke a few things. So the ones that NEED V.066 need it available.

It is the SAME with V.067

I don't think anyone at Artsoft is interested in doing anything Mach3 wise.

AND it has been posted a million times here so IF you don't know that V.066 CAN have problems nothing else will help you.

It would depend on what teh signaling requirements would be for teh device(spindleselection) Normally THAT would be controlled from a PLC and then teh PLC and Mach3 would talk to confirm actions.

ANti corner dive in Mach3 has an On/OFF control AND you can set teh level at which it kicks in as a percent of feedrate. IF you set teh level at 80% then when teh Combined Vel in Mach3 slows to a level of 80% of teh called feedrate it should LOCK out the thcdown motion. When the Comb Vel gets back above 80% it releases teh lockout and THCdown can work again.

The actual THC up/down with an outside controller is controlled at teh Controller itself NOT mach3  > IF you tried to let Mach3 do it it would be MUCH too slow.

NOW a GOOD THC controller has a screen interface that allows teh OP to setup teh THC control parameters ON SCREEN.

In the case of the CSMIO "IF" the internal controls of the THC are  done correctly it would be perfect.

I call that anti gap dive and yes it HAS to be controlled at teh THC level as it kows what teh voltage levels are.  Anti corner dive is a setting controlled from Mach3 BUT in the case of an outside controller the controller has to actually monitor teh process(Mix Vel) and restrict ONLY THCdown not up.

It is always much better IF you can controll all teh THC functions from Mach3 instead of manually setting teh THC values.  This makes it easy to base you cutting parameters based on material cut.

You can use Mach3 tool table to store and update values at program load . Then in your Cam you base your materials on tool# THAT works very well.

And that brings up CAM. I normally use SheetCam as it has been developed with plasma in mind not as an after thought.  Very adaptable to ANY plasma needs.

OK there are good things about a fast thc and bad things about a fast thc.

A fast THC makes it much more sensitive to things like corner dive, gap dive. With a fast thc you may find yourself having to set these features based on Plate thickness. What works well with thin sheetgoods may not work well with heavy plate.

DOes the CSMIO do anti corner dive based on Mach3 settings ?  Like Mach3 would do. Does the THC do anti gap dive ?? how adjustable is it ?? Does it have a spanvolt(deadband) setting ?  Can you adjust these from on screen ??

OH boy Hood are you in for an edumacation. With plasma you HOME z to find teh top of the material not to establish a real Z home. There are 3 main sensing methods ohmic tip, Remote offset switch, and floating Switch on Z. AND 2 possiblities of motion with each, G28.1 and G31

Now that is with the standard Mach3 methods. THere are actually many more but that is another story.

I would hook it up as a normal Mach3 thc setup , USE it for a while . I would bet you will not have any problems cutting what you cut.  I do it about every day with a slow stepper setup (;-).

Post exactly what you have in the script and a play by play of exactly what it does .

First where do you have teh ohmic sensor signaling to the Home or Probe input. That will determine whether to use G28.1 or G31.
