ok.

I was a little quick like normal.
My hopes of being a Mach4 Lua Guru are being dashed. LOL
I no longer get an error but it executes the move regardless of weather the switch is activated or not.

Thanks all again.

Craig,

The script goes in a macro.

It is at the start of a special homing macro I made.
Sometimes the Home Switch will be activated at the time I need to do the special homing routine.
So I want to look and see if the switch is activated then move back a set distance.

Mach4 General Discussion / input signals

Well all I am back with another episode of "I just don't get it" or "What the hell did I do wrong this time".
Once again thanks to everyone for all the previous help.
I thought I was getting to be a Mach4 Lua Guru........screeching halt here we are. LOL

I need to check if the motor 0 home switch is active and move off of it.
Through much searching I am unable to find anything that makes sense to me and I can get working.

Here is the code I tried.

local inst = mc.mcGetInstance()
   
   local hsig = mc.mcSignalGetHandle(inst, ISIG_MOTOR0_HOME)
   local MatHmLimit = mc.mcSignalGetState(hsig)
   if MatHmLimit == 1 then
      mc.mcCntlGcodeExecute(inst, "G91 G0 X-5")
      mc.mcCntlGcodeExecute(inst, "G90")
   end

Any and all suggestions other than jumping off a cliff are greatly appreciated.

Sorry I should have been more informative.
I am talking about the PLC Script in Mach4

Mach4 General Discussion / plc from macro

« on: March 15, 2019, 07:50:07 AM »

Is it possible to run something in the plc from a macro?
I guess what I am asking is if I have the plc look for a setting to do something else at that time.
Somewhat like Daz used in his video about homing workaround.

Mach4 General Discussion / skipping lines

« on: March 15, 2019, 07:45:05 AM »

Attached is a macro I made.
If I step through in the editor it works fine.
The first time I run it it works fine.
If I run it again it skips the second G28.1.
If I restart Mach it runs fine the first time again and so on.
It has a lot of commented out things that I have been trying so please ignore them.

Mach4 General Discussion / Thanks

« on: March 14, 2019, 09:49:48 AM »

Just wanted to put a general thank you to everyone who has helped me recently.
I know I missed some specific thanks.
I am also sure I will be posting more questions in the near future while I try to get my head wrapped around the Lua.

Thanks again,
Bill

Thanks,
