SwiftyJ, apparenlty my last post went in after yours LOL. I tried a bunch more stuff since then to no avail

It looks like you have been busy with what you did. I thank you a bunch for doing all of that!

I am about to give yours a try and say a little prayer and maybe sacrifice a chicken to the Lua gods or something in hopes that it works I will report back!

SwiftyJ,
Got it all loaded in. I get an "Error starting continuous jog" when booting up Mach4, but ignore it and continue....

With that said, this is kind of working and certainly must be a step in a better direction? It is actually completing an incremental move!

However, what I notice is that it is changing the Jog Rate and Incremental Jog Step  on the computer screen. My intentions were for this not to do that and only affect the Jog+ and Jog- physical buttons on the control panel. Otherwise you always end up on 2% Continuous jog. You have to cycle through those Continuous Jog positions on the switch to get back to the step jog settings and the last one hit is 2%.

This opens up a lot more for me to think about though. If you have any ideas to make it only affect the control panel and not the "on screen" jogging, please let me know.

I am thinking maybe the jog rate of the screen could be recorded before any of this happens somehow and put back when all the continuous jog inputs are at 0? so that the step jogs default back to whatever is on the screen when you go to those positions?

Again, thanks for taking the time to help me with this! In the mean time I will drink more coffee and brainstorm how to solve the above issues....getting there though...!

Missed my editing time window for above....I was going to mention...

I do have an off position on the Axis Selector of control panel. If that is useful for anything...

It looks like I can change this and it will put it back to 100% jog rate for the incrementals when you go there....not sure if this how it should be or not.
I still have to get the feedrate override selector going too....
function setJogInc(inc)
local rc, axisNum
local inst = mc.mcGetInstance()
--For each axis set the incremental value and jog type to inc
for axisNum=0,5,1 do -- X = 0, Y = 1, Z = 2
rc = mc.mcJogSetRate(inst, axisNum, 100)
rc = mc.mcJogSetInc(inst, axisNum, inc)
rc = mc.mcJogSetType(inst, axisNum, mc.MC_JOG_TYPE_INC)
end
end
Is Step jog usually done at 100% and slowed down with Feedrate Override (if you wanted to slow it down)? I do not have experience with other CNC mills. Maybe other mills only have switches for control and not duplicate "on screen" options?

Another note to solve:

If the axis selector knob is on the off position it breaks the code since none of the ones it is looking for is on. Having it in the off position activates pin 43

I will have to see if I can figure out how to make it disable the jog + and - buttons if it is in this position and not break the code for the other positions.

I wasted a bunch of time testing my changes using the Jog- button and nothing happening LOL. I finally figured out you had it on input 50 instead of 52.
I was able to solve the crashing if the Axis selector switch was in the Off position.
I also fixed the Jog being at 2% on any of the Step-Jog positions by adding a command to set it to 100% when any of the Step-Jog positions are selected.
The one thing I have not fixed yet is getting the  "Error starting continuous jog"  from popping up at Mach4 boot up.
This may be the only thing left to find a fix!
The error at bootup does not occur if the Axis selector switch is in the Off position, since this stops it from calling the jogAxis function.

I am tempted to just comment out the error, because it seems to work fine if you just ignore it on first bootup...
I am down to getting this on first bootup, even though things seem to be working okay and the ESS error seams unrelated to the topic of this thread. It is there even if I disable things for this thread.

-----ESS: Limit Switch triggered on
Error starting continuous jog
Error starting continuous jog

One other thing to note is that every once in awhile if I am on the x1 switch position, a jog will go 2 inches instead of just one...this is random so far as I can tell. Maybe to do with switch bounce while it is still moving? It thinks you hit it twice so it goes 2 inches instead of one. I wonder if there is a way for it not to accept another input until it finishes the move? This way if there was some switch bounce it would be ignored if it occurs after the initial press, and before it finishes moving the command distance from the first press.

If you want to stop the new code affecting the screen jog controls I can rewrite some of it using registers which would sort this out.

I think the reason you're getting the errors during start up is that Mach4 see's the input high and runs the jogAxis function. You can fix this by checking that the Mach is enabled in the Jog Plus and Jog Neg code in the signal library. There is a global variable that is set up at the top of the screen load screen 'machEnabled'. I believe you can use this e.g.
[mc.ISIG_INPUT50] = function (state) -- Jog- Input
if (machEnabled == 1) then
local axisNum = getAxisToJog()
if(state == 1) then
jogAxis(axisNum, mc.MC_JOG_NEG)
else
jogAxis(axisNum, mc.MC_JOG_STOP)
end
end
end,
Regarding the speed for incremental jog moves, Mach uses the current jog rate % when performing an incremental move. The feed rate control only affects g-code. You could set a different rate for each increment using the setJogRate() function

I've rewritten it using registers which tidies some things up a bit more, and also helps with diagnostics as you can see through the register diagnostics what the jog values are currently set to. It also doesn't affect anything on the Mach screen.

I have added checks to the Jog+ and Jog- signals to check that Mach is enabled (this should prevent errors on startup) and check Mach is at idle (this should help prevent sending a jog command while it is jogging, and also prevent errors if a button is pressed when running g-code or something).  It also looks at input 43 to check that the control panel isn't set to 'Off'

I have added code to input 43 so that if Off is selected while it is jogging, the jogging will stop. You can remove this if you want..

For each of the increment inputs I have added setCpJogRate(100) to set jog rate to 100. You could change it so you have individual speeds for each increment.

There are a couple of functions added/removed and signal library has changed so best to delete what I sent before. You will also need to add the registers via Configure - Plugins - Regfile  (Mach may need to be restarted after)

Double check all the input numbers, I think have them correct
