General Mach Discussion / MPG Mode won't stay on.

« on: June 03, 2015, 08:41:32 AM »

I have a 4 axis MPG pendant.  I am using a brain to turn on Jog Mode ---> MPG when the MPG pendant is switched to any of the axis "X,Y,Z, or A"; respectively when I switch the MPG pendant to "OFF"  the brain switches to Jog Mode ---> Cont. 
I know this brain works because I am using it on 2 other machines.  However, on this machine when I switch to an axis on the pendant it switches to MPG mode for a split second and switches back to Cont.  When I manually hit tab and cycle through the jog modes it doesn't switch to MPG Mode.  I have MPG 1 active in the ports and pins so it should at least toggle to MPG Mode but it is not. 
Side note, I do not know what shuttle mode is, but whenever i enable it it switches to MPG mode but it will not allow me to use the MPG Wheel.   ANY IDEAS???

Thanks TimGS!  I'll give it a look.  I'll be able to do some testing when I'm finished with a machine I'm working on.  I really want to get Mach 4 put on it.  Still have a little ways to go to get an understanding of Mach 4 and especially Lua.

General Mach Discussion / Axis calibration is changing.

« on: May 27, 2015, 02:48:42 PM »

We just redid a Johnford Super Vertical with Mach 3 and it has been running for about a month with no issues.  This morning we get to the shop and the calibration is off on the Z axis.  We have restarted the computer and even turned the entire machine off to reset anything that might be weird in the settings.  The servo drive has no issues; we reset it to default settings just to be sure.
We can just recalibrate the axis to work but we are afraid that it will do the same thing down the road. 

Any suggestions??

Thank you TP!!  I will just continue with the Macro then!

Hey  TP
We are doing that on one of our mills already, using a macro to deactivate and activate before and after A moves.  We were redoing a mill with Mach 3 that had Fanuc controls on it.  The Fanuc controller would automatically turn the brake on and off when the A moved, whether you are running code or just hitting the button to jog.  I was just hoping that there was a way to do what fanuc does inside Mach 3.  Thanks for the input though! Greatly appreciated!

General Mach Discussion / A Axis Brake

« on: May 18, 2015, 11:33:19 AM »

I am wanting to have a brake on my A Axis turn on when it is not moving and off when it is moving.  Is there a way to do this in Mach 3?
I would like for it to have a half second delay also.  So when I hit my keyboard Jog A + button it disables the brake and THEN starts jogging.  When It stops jogging it enables the brake and waits a half second before doing anything else.   ANY THOUGHTS??

In Mach 4 configuration do I need to do anything to setup the MPG?  That's more along the lines of what I was asking, sorry.  I haven't seen anything in Mach 4 that does anything to do with reading inputs from the MPG.

Mach4 General Discussion / MPG Setup ????

« on: May 15, 2015, 09:25:56 AM »

I have an MPG that I want to work with Mach 4.  I am using an Ethernet Smooth Stepper (ESS).  Under the ESS I/O configuration, I have my 2 input pins set to MPG/Enc 0-A and MPG/Enc 0-B.  From there I do not know what I need to do to get axis movement.  Eventually I will have a pendant for the machine so I can set up in the PLC script the inputs for axis selection and jogging speed/mode.  But for now I need to know just how to get movement via MPG wheel.

Mach4 General Discussion / Re: Output Control

« on: May 06, 2015, 01:37:46 PM »

A little bit more help.  This is what I'm using to give a start signal momentarily.  Turns on Output 2 for half a second then shuts it off.  I also show a message that it turns on and off.
Hope this helps.

--TEST CODE OUTPUTS!!
function m1010()

local rc = 0;
local inst = 0; -- mc.mcGetInstance(mInst)

-- Turns on output 2.
hsig, rc = mc.mcSignalGetHandle(inst, mc.OSIG_OUTPUT2);  
mc.mcSignalSetState(hsig, 1); --sets OUTPUT_2 to True

--Messages are written like this.
mc.mcCntlSetLastError(inst, "Output2 ON");

wx.wxMilliSleep(500) --Same as sleep in Mach 3.

-- turns off output 2
hsig, rc = mc.mcSignalGetHandle(inst, mc.OSIG_OUTPUT2);  
mc.mcSignalSetState(hsig, 0); --sets OUTPUT_2 to False

--Messages are written like this.
mc.mcCntlSetLastError(inst, "Output2 OFF");

end --This is for the end of the function m1010()

--This next part does not have to be in here to run in Mach 4.
--It does need to be in here to step through and test.

if (mc.mcInEditor() == 1) then
   m1010()
end
