Mach4 General Discussion / Re: Pause loaded cycle after certain amount of time

Oscar,
I'm not sure about the m30 not stopping the timer.  I don't see why it wouldn't.  Be sure it is saved as a lower case m30.mcs   . 
Also, you should be able to add the m3 to your resume timer.

That's entirely up to you.  I have a Carbide Knife Grinder in the shop that can move at 200+ IPM but I've got it set to 40-50 IPM because I don't want the operators to crash the machine because they aren't paying attention.

Bill,
There are already buttons to adjust the FRO. 
But you can use the code in this post below, see if it works.

Oscar,
You can make your own m30 that has the scr.StopTimer() in it.  All you have to do is make a new macro and name it m30.  
This will override the stock m30 that Mach4 uses.
Be aware of the functions that m30 takes care of automatically.  
Steve does a great job explaining what needs to be put back into a custom m30 in this thread.  His post is the 4th one down.

So when you make a custom m30, be sure to add back in the listed functions as well as adding your scr.StopTimer().

Gerry is correct.  lol  You will know when it stalls.  The table will stop moving and it'll make a funny noise.

I think Craig has given someone a good "formula" for stepper velocity before, somewhere on this forum.

But here at the shop, I keep bumping the velocity up a little at a time until the motor stalls; once I find where it is as fast as possible without stalling, I back off about 20%.  Works pretty good for us.

Daz just did a video on timer scripts.  I haven't tried this, this is just a theory.  Have a timer script to call a Feedhold and start another timer; once the second timer reaches it's limit call Cycle Start and restart the first timer.

Just an option, don't know if it would work, but that's where I would start.

Mach4 General Discussion / Re: Mach4 Spindle lag problems

I didn't have this problem when I first started using Mach4 on this mill.  Don't know what changed. 
I don't have this problem on any of my HiCON Integras.

My spindle does the same thing.  I'm running an AC motor with a VFD and not a servo, but none the less, after I jog it will sometimes wind down for a fraction of a second and wind back up.
Also running the ESS

Mach4 General Discussion / Re: PMC. Need help to toggle an output

« on: September 24, 2018, 07:12:27 PM »

As far as the FRO and SSO.  I plan on adding panel buttons to a lathe to adjust the FRO and SSO so I went ahead and worked on some code to do this.

--FRO is read from 0 - 250
--FRO + 10%
function FROPlus()
    local inst = mc.mcGetInstance()
    local FRO = mc.mcCntlGetFRO(inst)
    if FRO == 250 then
       mc.mcCntlSetLastError(inst, "Can't increase FRO anymore.")
    else
       local NewFRO = (FRO + 10)
       mc.mcCntlSetFRO(inst, NewFRO)
    end
end

--FRO is read from 0 - 250
--FRO - 10%
function FROMinus()
    local inst = mc.mcGetInstance()
    local FRO = mc.mcCntlGetFRO(inst)
    if FRO == 0 then
       mc.mcCntlSetLastError(inst, "Can't decrease FRO anymore.")
    else
       local NewFRO = (FRO - 10)
       mc.mcCntlSetFRO(inst, NewFRO)
    end
end

These are functions I made to increase and decrease the FRO by 10%.
You can add the function to a button in the signal script.  
Again, much like the coolant toggle discussion, just add this function into the signal.

The Spindle Override will read from 0.5 - 1.5.  So when you make the Script for them, just make it SSO = 1.5 and SSO = 0.5  and increase and decrease by 0.1

You can also have a "Reset FRO" and a "Reset SSO" button to set it back to 100%.
Just use the Set command and set it to FRO 100 and SSO 1
